Develop with Bluetooth Technology, You Must Know The Basics of Bluetooth Certification & Bluetooth SIG

2012-01-08T18:48:00.001-08:00

The previous article had been introduced the new technologies of Bluetooth v3.0 + HS and Bluetooth v4.0 + LE, so we will realize that Bluetooth wireless technology is making big breakthroughs in new markets. Next, let’s see how the Bluetooth SIG can help your company find new opportunities for your products.

Basically, the major test of Bluetooth certification can be divided into three dimensions, including

1. Radio Frequency:

To test the electric property, power, modulation and phase converter of Transmitter.
To test the sensitivity and anti-interference ability of Receiver.

2. Protocol:

To test the capacity of Protocol by verifying the language communication and command response accuracy

3. Profile:

To verify the relevant specifications, protocol and interoperability according to different purposes.

The above tests all have its corresponding test items which are set based on product categories and declared function. And the execution of each test must be in accordance with Test Case Reference List (TCRL) published by Bluetooth SIG. TCRL defines the types of test case under conformance test and interoperability test which are required for certification. The test cases can be divided into the following four categories:

Category A:

The test case is a mandatory testing and must be performed by an accredited Bluetooth Qualification Testing Facility (BQTF).

Category B:

The test case can be performed with/without a recognized BQTF, but it must use approved equipment to test, and submit test data as test evidence.

Category C:

The test case must be performed with certified products, but no test evidence is required. Only needs self declaration.

Category D:

The test case is preliminary or about to be retired. It has no official qualification value so no test is required.

As mentioned above, we can realize that there are many details must be noted regarding Bluetooth certification test cases. Moreover, the procedure of Bluetooth certification becomes more complicated than ever before because of the quantities of Bluetooth versions and the divergence of Bluetooth specifications.

How to determine which Bluetooth specification your products belong to? The Qualified Design Listings (QDLs) developed by Bluetooth SIG can help. QDLs defines the types of Bluetooth devices, including Controller Subsystem, Host Subsystem, Profile Subsystem, Component, and End-Product. These devices are regarded as different Bluetooth device specifications upon the different versions adopted by their components. Figure 3, which shows a decision table of Bluetooth device specifications developed by Bluetooth SIG, can help the manufacturers on how to determine which Bluetooth version their products belongs to. However, because there are plenty of possible combination in devices, it is still difficult to identify the right version even with the decision table.

Other than the difficulties of version identification, there are also many restrictions and regulations while the practical certification test are performed. Take the certification of Bluetooth v3.0 + HS as an example; the subject must conform to the following precondition for application:

Bluetooth controller must be Bluetooth v2.1+EDR or Bluetooth v3.0.
WLAN 802.11b/g controller must be Wi-Fi certified, and follows Bluetooth 3.0 Host Stack structure and 802.11 PAL protocol.

As to Bluetooth v4.0 + LE, because its Bluetooth architecture is different from legacy ones in the physical layer, protocol layer and application layer; also, Bluetooth v4.0 + LE has single-mode and dual-mode, the certification requirement is much more different from the past.

BQE－the powerful assistant for the application of Bluetooth certification

Both the diverse regulations and sustainable technical updates cause the manufacturers much trouble while seeking Bluetooth certification; for this reason, it highlights the value and importance of the Bluetooth BQE (Bluetooth Qualification Expert). The professional Bluetooth BQE is recognized by Bluetooth SIG, and its main mission is providing the consultation for Bluetooth certification. When the device manufacturers want to get certification for their products, they can nominate a Bluetooth BQE for QDL registration. The Bluetooth devices which are certified and finished the QDL registration by a Bluetooth BQE will not be audited within three years, and it also represents the trust of Bluetooth SIG for the profession of Bluetooth BQEs.

Figure 4 shows the procedures of Bluetooth certification of Bluetooth SIG. Based on the procedures, Allion Test Labs can provide many consultations which include:

The consultation and technical support about the specification and version of Bluetooth device.

As mentioned above, the difficulties of Bluetooth version identification is that it’s hard for the manufacturers to identify the Bluetooth versions of their products even with the decision table; in this case, they need the professional assistance from a reliable Bluetooth BQE.

Test item evaluation including the required test projects, test period and test fee.

Bluetooth certification test is very complicated, especially the test cases may be varied upon the types and controller versions of each device, the Bluetooth specifications, and the regulations of the present TCRL. Thus, in order to avoid the misjudgement that might cause unnecessary retest, The mandatory test cases must be confirmed before practical testing. Otherwise, Bluetooth BQE can pre-estimate the period required and predict the certification test fee to assist the manufacturers in schedule and budget control.

Bluetooth documentation consultation and review support

During the process applying for Bluetooth certification, there are many documents and forms must be completed; for example, the manufacturers need to fill out the Protocol/ Proﬁle Implementation Conformance Statement (PICS) which includes all applicable functions of Bluetooth devices. Also, all features stated in PICS must be tested with the regulations of Bluetooth SIG. And Bluetooth BQE hereby stands a role to assist the manufacturers in filling out relevant documents which contents should conform to actual situation and test regulations. In addition, Bluetooth BQE can also assist the manufacturers in developing the test plan or reviewing the applicability of the test plan to avoid the possibility of application rejection or errors found in following audit.

Find suitable Bluetooth Qualification Test Facility (BQTF)

Although all BQTF are recognized by Bluetooth SIG; in addition to execute the certification test, each BQTF has difference service coverage, amount of equipments and the ways of schedule arrangement. Thus, it will be the most time-saving way to choose suitable BQTF through Bluetooth BQE.

Problems debugging and issue identification

Besides consulting support before testing, Bluetooth SQE can also provide problem debugging and issue identification support based on the test result. Due to the regulations of Bluetooth SIG, Bluetooth BQE and BQTF must belong to different executive departments, and often different institutions, to maintain the independence and reliability of Bluetooth BQE.

Test Result Review

To ensure that the test result conformed to the regulations and the content of submitting PICS, Bluetooth BQE is able to review the result after testing to reduce the probability of rejection by Bluetooth SIG.

Upload the result of test (TDU)

BQE will help the manufacturers upload the TDU to Bluetooth SIG for further examination. This action will be specified and represents an initial review is done by BQE.

Qualified Design Listings and Qualified Design ID

Continuing the previous description of the BQE services, the ultimate goal of the manufacturers is to make the device pass the certification test, list in QDLs, and get the QDID. All above are also the consulting ranges of BQE.

Figure 4: The procedures of Bluetooth certification.（Source: Bluetooth SIG）

In sum, BQE plays an important role in the entire certification procedure. From the membership application, test plan submission, certification test execution to product listing, BQE can provide substantial technical support. Therefore, BQE is considered the best approach for most manufacturers seeking consultant and troubleshooting service.

The spectacular innovation of Bluetooth technology

Diversified developments of Bluetooth technology attempt to create a more convenient environment for consumers, so that they can enjoy much easier, simpler and faster life applications. For the manufacturers, the precondition is to ensure the products are conformed to Bluetooth specification with high interoperability. All above have to depend on the endorsement of Bluetooth Qualification Test, and further the device interoperability test.

Allion Test Labs is a global engineering service and validation consulting firm conducting certification, interoperability, performance and compatibility testing services for companies all over the world. In addition to provide BQE service and support, Allion Test Labs prepares a large number and variety of Bluetooth devices to satisfy the demand for Bluetooth interoperability test in the market today. In the future, Allion Test Labs will look forward to help more manufacturers be certified and provide consumers with higher quality of Bluetooth products.

The Next Bluetooth Wave: High Speed & Low Energy Technology

2012-01-02T18:32:00.000-08:00

Without external network connection, Bluetooth technology defines a uniform structure for a wide range of devices to connect and communicate with each other. Thus, among the wireless transmission technologies, Bluetooth technology is a short-range communications technology that is very convenient and secure. Nowadays, you can find it in billions of devices ranging from mobile phones to desktops or laptops.

However, with the innovations of Bluetooth versions(Bluetooth v2.0/2.1 + EDR, Bluetooth v3.0 + HS to Bluetooth v4.0 + LE), constantly-evolving Bluetooth profiles, and the pervasiveness of multi-mode application, the whole concept of Bluetooth implementation becomes more complicated than ever before and further turns into a challenge for corporations seeking certification. To help you get a clear picture of Bluetooth certification, this article will introduce the latest Bluetooth versions and clarify some commonly confused concepts.

Let’s understand Bluetooth v3.0 + HS, Bluetooth v4.0 + LE, and what’s multi-mode application?

Currently, Bluetooth v2.0/2.1 + EDR are still the most common versions in the market, the recent Bluetooth v3.0 + HS and Bluetooth v4.0 LE are released though. It’s very important to understand each characteristic of Bluetooth v3.0 + HS and Bluetooth v4.0 + LE.

1. Bluetooth v3.0 + HS

The so-called “HS” of Bluetooth v3.0 + HS means “High-Speed”, which makes

the transmission application of Bluetooth extends to larger files, including high resolution images or video/audio data. Thus, Bluetooth v3.0 + HS is often referred to as Bluetooth High-Speed technology. The main characteristics of Bluetooth v3.0 + HS include Generic Alternate MAC/PHY Protocol (AMP), 802.11 Protocol Adaptation Layer (PAL), Unicast Connectionless Data (UCD) and Enhanced Power Control (EPC).

Among all these features, Generic AMP is a major breakthrough of Bluetooth technology. That is, when large amounts of data need to be sent, the high speed alternate 802.11 PAL will be used for data transmission through AMP. In addition, UCD permits small amounts of data to be sent without establishing L2CAP channel. It is intended to lower the reaction time and power consumption while rapid connection or small data transmission is needed. Last, EPC allows devices to enhance the capacity of power control to support multiple modulation modes, so that can optimize the transmission distance.

Bluetooth multi-mode application is beginning to take shape by both Generic AMP and 802.11 PAL. It means that under the premise of preserving the original pairing connection of Bluetooth, the device can still use different wireless technologies upon different functions and demand for transmission. For consumers, they can remain the same operating mode as Classic Bluetooth to experience the multi-mode application without any manual settings for different wireless connections. For instance, data transmission and connection over Wi-Fi, is a typical case of Bluetooth multi-mode application.

How does the Bluetooth multi-mode application begin? In fact, Bluetooth SIG which proposed the concept of integrated wireless communication in 2007 tried to take UWB, NFC, Ultra Low Power, Wi-Fi, and other communication technologies under the Bluetooth technical architecture. That is why as mentioned above, the following revision of Bluetooth v3.0 + HS adds the technological application of Generic AMP and 802.11 PAL.

So far, Bluetooth v3.0 + HS has begun to be widely used in transmitting files, such as the adoption of FTP and OPP; moreover, it increases the transmission speed from 3 Mbps to 54/108 Mbps through 802.11g. Thus, the most compelling characteristic of Bluetooth v3.0 + HS is to achieve faster and smoother experience of transmission. While major chipset companies are speeding up the technology integration with 802.11n, Bluetooth v3.0 + HS will be able to support even higher transmission speed. In addition to file transmitting, Bluetooth SIG also integrates the relevant protocol positively to enter the field of wireless video transmission.

2. Bluetooth v4.0 LE

The so-called “LE” of Bluetooth v4.0 + LE means “Low-Energy”. Bluetooth v4.0 + LE, is like three specifications in one－Classic Bluetooth technology(e.g. Bluetooth 2.1+EDR), Bluetooth low energy technology, and Bluetooth high speed technology －all which can be combined or used separately in different devices according to their functionality(Figure 1). The key feature of Bluetooth v4.0 + LE is Low-energy, which means that it enables a Bluetooth device to operate for months or even years on tiny, coin-cell batteries. That is, Bluetooth v4.0 + LE allows Bluetooth devices in sleep mode while idling, and only initiate the Bluetooth functions while transmitting.

Another significant feature of Bluetooth v4.0 + LE is the so-called Single-Mode and Dual-Mode. In Single-Mode, Bluetooth v4.0 + LE can achieve the purpose of low-energy transmission through simple device searching and point to multi-point data reansmission. And in Dual-mode, Bluetooth v4.0 + LE can co-work with different Bluetooth specifications, such as Bluetooth v2.1 + EDR and Bluetooth v3.0 + HS, and then users can switch the operations of high-speed or low-energy upon ones’ demand. Therefore, the manufactures can adopt the appropriate mode, based on the purpose of device-using more flexible. For example, Single-mode can be applied on some devices which need long time but no sustainable data transmission, and Dual-Mode can be applied on some devices which need to transmit with other different products (such as computer or mobile phone) simultaneously.

Bluetooth v4.0 + LE enables classic and low-energy Bluetooth technology to exist independently, but also coexistence of shared; because of this evolution, the application of Bluetooth v4.0 + LE becomes more diverse. On one hand, lower-energy technology applies on healthcare electronics and fitness equipments; on the other hand, high-speed technology allows data-transmitting more time-saving. For example, one sphygmomanometer with Bluetooth v4.0 + LE can run only low-energy to record the subject's blood pressure status, and use classic Bluetooth technology to transmit data or images to the database. Different from the past point-to-point connection, Bluetooth v4.0 + LE uses the framework of Topology to allow more devices connecting with each other easily.

As a global standard, Bluetooth technology is in billions of devices worldwide, including virtually every mobile phone, laptop, tablet, new car, and more than 40 million medical devices. The brand-new Bluetooth technologies, such as Bluetooth v3.0 + HS and Bluetooth v4.0 + LE, will cut through the complexity of wireless communications, enabling devices to communicate seamlessly. In the future, Bluetooth technology and devices will bring simplicity to everyday life through their convenience, freedom, and ease of use.

The Rising Technical Standard (3): Car Connectivity Consortium

2012-01-01T20:03:00.001-08:00

In recent years, consumer electronics (CE) products with smart features have always become the hottest topic in everywhere. Apart from the already widely-spread CE products, the automotive field has also started being part of the“smart family”. For the automotive market, the Smart Car must be more functional and user-friendly to allow advanced technology adoption, such as In-Vehicle Infotainment (IVI) and satellite navigation system.

As the core device for in-vehicle connectivity, Smartphone plays an important role to make car 'smart' in the in-car environment. Thus, two different market fields – Smartphone and In-Vehicle Infotainment, must be compatible with each other. With so many different technologies and functions are added to these two product types, it becomes challenging for them to work together effectively. With the needs of two-way connection between Smartphone and in-vehicle monitor, the latest standard MirrorLink™ introduced by Car Connectivity Consortium is therefore released.

The Car Connectivity Consortium was launched by eleven companies across different industries, which include known mobile phone manufacturers Nokia, Samsung and LG Electronics; vehicle manufacturers Daimler, General Motors, Honda, Hyundai Motor Company, Toyota, and Volkswagen; and system suppliers Alpine and Panasonic. Currently, it has 26 adopter members. The vision of CCC is to develop an open and common connectivity technical standard for IVI and corresponding mobile devices like Smartphone. In addition, the purpose of promoting MirrorLink™ standard is to develop a complete and qualified certification test plan through in-depth technical development and an open infrastructure, hence the quality and connectivity of certified product can be enhanced. As the picture indicated below, to enjoy a convenient in-vehicle user experience through MirrorLink™ is actually pretty simple. User only needs to connect a mobile device with the car to sync Smartphone functions on IVI system such as hand-free answering and audio playback.

Apart from the major applied product lines like Smartphone and MP3, the future goal of product application includes tablet PC, e-book and small notebook. Even though the connectivity technology of Smartphone and car has been recognized in the market from the beginning of the time, vendors still have to keep tracking market demand in order to satisfy different types of consumers. To ensure that a product meets consumer's needs, standard certification plays an extremely significant role in product development. As CCC's Qualified Test Laboratory (QTL), Allion will keep assisting CCC to promote the MirrorLink™ standard/ technology and its certification program.

The Rising Technical Standard (2): MHL

2011-12-27T23:12:00.001-08:00

Along with the mature high-definition video display technology, people have higher expectations on audio/video experience today. For consumer electronics (CE) devices and home entertainment products, supporting HD audio/video transmission has become an essential requirement. However, while the tendency of mobile devices' form factor is smaller and smaller, making a product design embedded HD signal transmission interface has become challenging than ever. Also, the high power consumption of HD signal transmission is also a key element that impact the standby time of mobile devices. With these above situation and the increasing needs of mobile audio /video streaming, the latest mobile HD connectivity technical standard – MHL (Mobile High-Definition Link) is therefore released.

MHL is promoted by the MHL™ Consortium, comprised of five well-known corporations: Nokia, Samsung, Sony, Toshiba and Silicon Image. Currently, it has more than 60 adopter members. Due to the focus of the needs of HD audio /video streaming on portable products, the MHL™ Consortium developed this technology to transfer HDMI signal through an existing micro USB port. As the picture indicated below, we can simply see how this technology works: audio /video content on mobile devices can be transferred to HDTV immediately through a single cable.

MHL technology needs only five pins to support up to 1080p uncompressed HD video transmission with 7.1 channel surround sound, while also supports HDCP. In addition, mobile device can use MHL for power charging and increase the standby time. It also allows TV remote control to control the mobile device for audio /video content transmission and display. These kind of simple applied scenarios allow consumer products such as cell phones, TVs and notebooks to gradually adopt the MHL technology. For instance, Samsung, Toshiba and HTC have released their cell phones, TVs or tablet devices respectively that adopt MHL technology within this year.

As we have observed, the increasing demand for HD audio/video transmission is easily recognized. For mobile device vendors, the biggest niche to adopt MHL technology is that they only need a single micro USB interface, and then they can have all MHL features including battery charging and HDMI signal transmission support. No additional space will be required for individual micro USB and HDMI interfaces. Therefore, this well-integrated interface technology has been regarded as a killer application.

As MHL's Qualified Test Laboratories (QTL), Allion provides certification testing services to help vendor go deep into MHL technology. For more details about MHL and its compelling features, please refer to MHL official website at http://www.mhlconsortium.org.

The Rising Technical Standards (1): Continua Health Alliance

2011-12-05T18:59:00.001-08:00

To pursue a better quality of life, people put a lot more efforts into exercise and diet today. The healthcare market is getting bigger while the rate of aging is rising, many kinds of reasons have raised the importance of medical electronics, and the increasing importance allows healthcare industry to come up with its own technical standard.

The Continua Health Alliance (CHA) was established in 2006 by different health institutes and well-known corporations such as Intel, IBM and Philips. The Continua Health Alliance expects to use its regulated connectivity technical standard to ensure certified medical electronic devices and products can be compatible with each other. Additionally, due to the combination of Information & Communication Technology (ICT) and healthcare equipments, this technical standard can be very helpful in the telehealth field.

How do we know that? The picture below indicates the current technical structure of the Continua Health Alliance technical standard. Under the CHA's technical structure, the applicable range of products includes thermometer, blood pressure monitor, glucose meter and weighing scale. Apart from those products which we can easily see in our daily life, there are also the fitness equipments like treadmill, the healthcare devices like health monitor. Based on ISO/IEEE 11073 medical / health device communication standards, it adopts Bluetooth, USB and ZigBee connectivity technologies as data transfer between devices.

Briefly, this technical standard allows physical records under these devices to transfer to PC through Bluetooth, USB and ZigBee connectivity technologies, and keeps recording and monitoring the patients' health condition through Internet or Wi-Fi to transfer physical records to telehealth service center.

In this way, health monitoring can be much easier and effective, which allows professionals of medical and healthcare industry to understand patients' conditions in real time. Therefore, The CHA technical standard has begun being adopted by related manufacturers. Getting the certification of the CHA technical standard can help enhance the quality of vendors' products and build customers' trust compared to other non-certified products. With years of Bluetooth and USB test experience, Allion is able to provide test solutions throughout medical electronics product development stages. We have involved in and will constantly dedicate in medical electronics field to assist vendors to ensure the quality of its product and create a better healthcare environment.

SSD Quality and Performance Comparison - A Testing and Evaluation Report for SSDs in the Market Today (2)

2011-11-29T02:41:00.000-08:00

Since the last article “Exploring the Quality of SSD – A Testing and Evaluation Report for SSDs in the Market Today” was released in the end of 2010, we have received a large amount of positive feedback from readers and followers. In order to response to all the requests from our followers, we are releasing a follow up test report with latest SSD products. Hoping this report could provide valuable information when you purchasing a SSD drive.

Allion's interest is to perform a fair test and acquire valuable test results. We have pre-defined some criteria of test environment and test condition.

● SSD drives selection

There are four requirements when we select SSD drives for test:

Products can be bought in the beginning of 2011
Products have either 250 GB or 256 GB of storage space
Price range is between US$ 500 to US$ 650
The declared read/write speed of products can reach between 200 MB/s and 300 MB/s

Base on these requirement, we have selected eight SSDs from market for test: (Please refer to Table 1 for more drive information)

Table 1: DUT

● Test Environment

Test system. In this test experiment, we use same test platform for all tests.
Test tool. We have utilize several benchmark test tools from the market and Allion's self-developed benchmark test tool to perform the tests.
Test scenarios. Average Read/Write Performance, Sequential 64K Read, Sequential 64K Write, Random 16K Read, Random 16K Write, Random 4K Read and Random 4K Write. Test was run for seven days.
Test work load. In our test, we adopt several file formats for SSD read/write test.
Test time. We have performed a continuous 7 days test.

● Evaluation Items

Reliability
Performance Evaluation
Performance Stability
Performance Degradation

Result Analysis:

1. Reliability

The purpose of reliability test is to check if data access error will happen during data read/write, i.e., incomplete read/write or data lose. The main task of SSD is to accurately store and retain data, any data loss will result in serious damage to users. The reliability of SSD is a very basic evaluation item in this test experiment.

In our test, we examined if the SSD's SATA connector meet the SATA I-O's requirement. We also verified that the devices detected by test system without problem. After the basic spec checked, a serious of data read/write commands were sent to the SSD drives. Our experts compared and analyzed both data sets to see if there is any data lose. We used Allion's in house SSD stress tool pro to access all SSD drives for quite a long time. All tested SSD drives pass this test.

2: Performance Evaluation

As we know, high speed transmission is one of the SSD highlights. To check if the actual performance of these SSDs match their announced results, we stimulate real user behavior (i.e. different file size, various file formats) to access those SSDs and record the test result. We can look at the result from two different aspects.

1) Performance Test Results Comparison

Table 3 is the result of the SSD performance test on pure read/write test.

Table 3: Performance Test Results (MB/s)

The performance of each SSD is different. Under the condition of same test time (7 days), the total read/write count for each SSD were different. The SSD which has better performance had more total read/write count, vice versa. The test result that we present in Table 3 is the average number of the read/write result over all read/write count.

Picture A: Performance Test Results

Table 3 test result also indicate result from different test scenarios. Turning Table 3 number into chart, we can observe that SSD tend to have better performance when dealing with larger files (64K reading process) compared to smaller files (16K and 4K reading process) on average. In general, the speed of data reading is faster than data writing for storage media, Samsung does have similar read/write performance on all file size. On Patriot SSD drive, we can see an obvious performance drops when dealing with 16K and 4K data file [drops down from 160 ~170MB/s (64K) to 22MB/s (16K), even close to 3MB/s (4K)].

Among these tested SSDs, Adata, Intel and Samsung are having better performance than others.

2) Comparison of Declared Performance vs. Actual Achievement

Most of the SSD product will declare “max read/write” and “average read/write” number on the product specification. What is the actual read/write speed that users will get when they buy the SSD from the market? We also compare the test result from this perspective. We ran a 7 days long read/write stress test. We selected “64K sequential read” and “64K sequential write” test data for comparison since 64K read/write tend to have better performance than other file sizes.

Table 4: 64K Sequential Read/Write Maximum and Declared Performance Comparison

We summarize the best read/write performance result we got during the test from our test data in Table 4. By looking at this table, we notice that OCZ SSD can reach their declared “read” performance. The rests only can reach 83% to 97% of the declared performance. Most of the test drives can reach the declared “write” performance.

If we look at the result from “average read/write” point of view (we average all the read/write performance result to get this number), we will see slightly different result. Table 5 is the summary of test result. We notice that no SSD could reach their declared “read performance.” On the declared“write performance,”only 4 out of 8 SSDs could reach that number.

Table 5: 64K Sequential Read/Write Average and Declared Performance Comparison

Compared the actual results with declared performance from vendor, OCZ is the most outstanding one among these SSDs.

3: Performance Stability

The purpose of this test is to evaluate if tested SSD can still remains steady performance after a long time access. Two factors might affect SSD drive's stability in our observation: long time access to the drive by using sequential and random data type and use up all the storage capacity recursively. We analyze the performance stability from following perspectives.

Performance Normal Distribution:
We use 95% as our analysis criteria. 95% (and above) of the test results need to fall into the range of +/–10% of average read/write performance range.
High/Low Gap over Mean:
The difference of the leading group (mean of the top 10% performance result) and the lagging group (mean of the last 10% performance result) must be lower than 20% of overall average performance result.
Standard Deviation over Mean:
The standard deviation over mean need to be lower than 10%.

1) Performance Normal Distribution

We will observe the overall test result distribution. If all results are close to the µ, it means the drive is relatively stable. If the result distribution fall widely that means the drive is relatively not stable.

We use “95% and above of the read/write performance results need to be in the range of +/-10% of the average read/write performance results” as our analyze criteria. We summarize the read/write performance result in table 6. We can see that four out of eight SSDs can reach the criteria. OCZ is the one has the best normal distribution performance result.

Table 6: Performance Normal Distribution Test Results (Overall Read/Write Performance Test)

If we look at the distribution result by graph, we can see that in best case (graphic B), all test results (blue dots) fall into the upper/lower green lines area (+/–10%). In bad case (graphic C) most of results fell out of upper/lower green line area.

Picture B Case: Good Performance Point Distribution (Read/Write Performance Test)	Picture C Case: Bad Performance Point Distribution (Read/Write Performance Test)

2) High/Low Gap over Mean

High/Low Gap over Mean is an indicator of the stability of a SSD drive. We will compare the difference of the best and worst performance for the designated SSD. The closer the gap is, the more stable it is. In our analysis, we use this criteria: The difference of the top 10% best performed SSDs and the last 10% least performed ones must be lower than 20% of overall average performance.

Table 7 High/Low Gap over Mean Test Results
(Overall Read/Write Performance Test)

We do use that 4 out of 8 SSDs perform as expected while read/write performance test is undertaking, OCZ and Corsair are two of the bests among these four devices. On the contrary, 2 out of 4 drives were having even larger than 60%of the result. Even though the gap of ADATA and Patriot are close (7.63 and 8.22), there is a big difference between means (72.71 and 37.98), therefore, the evaluation results are significantly different (10.49% and 21.64%).

3) Standard Deviation over Mean

Standard deviation over mean is another good indicator to evaluate the SSD drives' stability. In this analysis, we observe every SSD drive's test result against their average result. Out analysis criteria: The dispersion of all test results must be lower than 10% of overall average performance to meet the expectation under this section.

Table 8 Standard Deviation over Mean Test Results
(Overall Read/Write Performance Test)

Let's take OCZ's result for example. It has σ=1.04, μ=78.03MB/s and σ/μ=1.34%. That means most of the read/write test result fell within +/- 1.04MB/s. The σ/μ=1.34% indicate a very stable performance. 5 out of 8 SSDs meet our criteria.

4: Performance Degradation

Performance degradation means SSD's performance declines after certain time of use and wear out. Performance degradation will also impact the usable storage size. Lack of TRIM, Garbage Collection function not well-designed or insufficient Space Provisioning will affect overall performance measurement. In our test, we run a 7 days complete read/write test. The drive is having performance degradation if the difference between first and last cycle of the seven-day test is greater than 10% of average performance (to write data completely into all SSD storage area as a cycle).

We did observe 3 tested SSD has performance degradation. Picture D and E are shown as an example of performance degradation. From picture D we can see that this SSD is able to reach up to 80~90 MB/s of performance in first cycle rounds, then reduce to 70MB/s. The average performance between first (pink) and last cycle (blue) has 11MB/s difference as shown in picture E.

Picture D Case: Performance Point Distribution (Read/Write Performance Test)	Picture E Case: First and Last Cycle Rounds Average Performance Comparison (Read/Write Performance Test)

Picture F SSD Key Point of Product Testing

Even though the features of these SSD devices that we selected to test are similar, we can still see different result in different test conditions. SSD still needs a long-term development process; market acceptance will stimulate product technique to keep improving and growing to the next level. With years of research and product test experience, Allion expects this evaluation index would be a useful reference for readers. Along with the growing of technology, we hope to see more SSD products with the better quality and technique in the near future.

To Look at Developing Point of Technology Standardization from New Technology – TransferJet as the Example

2011-08-23T01:14:00.001-07:00

In our daily life, many different techniques are applied on countless electronic products to render its function. If those techniques are self-developed by each individual company, it is highly possible to limit the industry's evolvement and the technique's further advancement. To avoid the hydra-headed situation, the concept of“technology standardization”is thus given birth to universalize popular technologies in the market. The purpose of technology standardization is to formulate a usable technology to become the applicable standard for all vendors to adopt and use. Therefore it can not only make a technology to be widely adopted, but also to avoid industrial monopoly on particular technology to pursue one's own commercial interests.

To successfully standardize each technology, a third-party and non-profit organization is required to play the key role of promotion and advocacy This kind of neutral association is responsible for many aspects such as internal operating, technical specification defining and certification programs setting. Thanks to the effort from these standard associations, there are numerous technologies have become popular industry standards today. For example, consumer electronic products like mobile phone & cameras and home appliances like televisions & DVD players has adopted current hot technology standard including USB, Bluetooth and HDMI.

As a leading third-party authorized test lab, Allion keeps working closely with standard organizations/associations to jointly promote the technical standards and help manufacturers obtain the association's latest technical updates. In addition to many popular industry standards like we mentioned above, TransferJet is another new technology that we'd like to introduce. TransferJet is developed by SONY and other well-known vendors and the organization behind it is called the“TransferJet Consortium”. It is a stand-alone unit to promote this innovative transmission technology.

To help you understand what should be focus on when it comes to technology standardization, below we take TransferJet as an example to discuss about some key points:

1. Association's strong support for long-run operating

A successful technology standard definitely needs the association's strong support. To be more specific, it's the member companies to actually back up and stand for the standard. A technology standard must have early adopters to attract more supportive vendors to follow up. In this situation, large companies usually have more manpower and resources to do early-stage R&D errands and adopt such technology standard into their spec. Therefore, those associations are often formed by a certain global branding corporations.

Let's take a look at TransferJet. The TransferJet Consortium was initially established by 18 international companies, such as SONY, Toshiba, Panasonic and Samsung. Except for the 18 promoters, there are 36 adopters joining this association cumulative to end of February 2011. These members play the role of checks and balances to provide proper suggestions and opinions in adopters' points of view. To let an association run smoothly, division of labor is required for efficient operation. In TransferJet Consortium's case, three working groupies are divided for technical, certification and marketing purpose. This working pattern equipped the association with a complete and sound structure.

2. Unique and irreplaceable technology

Another key point is that a technology standard needs to retain its uniqueness to keep it self from replacement or duplication. The reason is that vendors would be willing to invest time and effort into a technology standard if it has a highly innovative and exclusive business value.

TransferJet represents its unique technology on this one. The TransferJet Consortium is dedicated in developing close proximity wireless transfer technology which applies NFC (Near Field Communication) technique. The 3 cm data transfer range can easily protect users from the risks of interference or file copy during the transfer process. Unlike traditional NFC, TransferJet allows larger file transferring (up to 560 Mbps) by using UWB (Ultra-Wide Band). This also matches the three declared features of TransferJet: Simple Operation, Safe Connection and Efficient Transfer.

3. Ease-of-use and the potential to be widely adapted

End users care about the most is whether a technology is easy to use without complicated manual settings. TransferJet is an example which applies this concept to its design; data transfer between devices with just a single touch is the highlight.

TransferJet provides some scenarios we can imagine: We want to share photos which are just taken with friends while traveling; we can either send them through email later or burn another Compact Disc after transferring them to the USB drive. Through TransferJet technology, certified devices are able to transfer data with each other in the blink of an eye; therefore, we can share photos immediately and send them to the printer with just a single touch.

TransferJet technology applies to many consumer electronics products such as cameras, camcorders, cell phones, TVs and tablets PCs. It is also planned to expand the future development into digital signage, automotive and healthcare fields.

4. Complete certification management

In a successful technology standard, the third-party test lab is a critical segment in its association to set up the certification testing procedure. The role of third-party test lab is important to assist vendors' products obtain the certified logo and provide consulting service. In addition, the test lab helps monitor the quality of vendors' products and ensure all certified products are well-performed and compliant to the specification. As TransferJet's Qualified Test Laboratories (QTL), Allion provides certification testing services to help vendor go deep into TransferJet technology. Recently Allion is working with TransferJet Consortium closely by holding technical seminars to let local vendors learn more about this unique technical standards, Allion will continue to stand in a professional third-party lab of cooperation with the technical standards to promote the standardization of more industrial technologies.

Is Thunderbolt A New Threat to USB 3.0?

2011-06-22T01:43:00.000-07:00

Thunderbolt, formerly called ‘Lightpeak’, is Intel's new high-speed I/O technology through a single port that is first available on new Apple MacBook Pro notebooks lately. Fast data transfers are Intel's main claim, such as 10 gigabits per second transfers and dual-protocol support. The dual-channel design allows for two channels on the same connector at up to 10 gigabits per second that can support both PCI Express and DisplayPort technologies. Compared with existing technologies, Thunderbolt is regarded as a combination of HDMI and USB 3.0, the loading quantity is spectacularly huge through its co-invented PCI Express 4x, which can connect external devices directly to Macbook Pro.

* Thunderbolt Structure by Intel

USB 3.0, also called SuperSpeed USB, is the latest specification that can transfer data between devices, which is 10 times faster than USB 2.0. Even if USB 3.0 data transfer rates (up to 5 Gbps) are lower than Thunderbolt (up to 10 Gbps), U3 technology is still unbeatable. To recognize more about Thunderbolt and USB 3.0, we analyze the difference between these two technologies through two categories - price and industry standard.

1. Price

Thunderbolt will hold a price premium because the controller is made only by Intel. The cost of making a 10Gbps Ethernet chip is clearly higher than a 5 Gbps USB 3.0 chip. Additionally, a unique five-wire cable is required which is supplied only by Apple. Many other costs could be hidden since Apple is the only one adopting Thunderbolt.

2. Industry Standard

Nowadays, USB has become the most widely accepted and commonly used standard in the PC industry. USB technology has over a decade of adoption since it was originally released in 1995, strong consumer brand recognition has been made due to widespread adoption of USB. The popularity and the consumer demand are even higher along with the recent release of USB 3.0. Thus, a new technology needs time to hold a stable position in order to expand its market share. Intel cannot ignore the increasing demand for USB 3.0.

Now it's been a while since Intel's announcement, but it's too early to tell if Thunderbolt will be a real threat for the already existing USB across the PC OEMs. Which one will become the industry leader in the future? Only time will tell!

Key Points of Product Testing in Automobile Electronics Market: In-Vehicle Infotainment System V.S. Bluetooth Cell Phones

2011-05-02T20:26:00.001-07:00

Along with the trend of smart portable devices, automobile electronics market is now taking a spot besides of smartphone and smart TV. Recently, the majority of people are getting familiar with the term “Smart Car”; user-friendly design that combines automobile with three fields: information, communication and entertainment. In-vehicle infotainment system is now the major trend in automobile electronics product development.

In general, the range of automobile electronics is very voluminous, such as Tire Pressure Monitoring System, Electronic Stability Control, Smart Grid, Electronic Car and In-Vehicle In fotainment. Today we will focus on in-vehicle infotainment system since it relates to end users the most.

In-Vehicle Infotainment Systems and Bluetooth Connectivity

Lately, we can see that some car manufacturers have brought out its own solution, such as Ford and Toyota.

1. Ford SYNC

* Ford SYNC

Ford SYNC platform is a fully integrated in-vehicle communications and entertainment system, which allows users to control their cell phones and MP3 players via wireless connections and voice commands.

2. Toyota Entune

* Toyota Entune

Toyota Entune infotainment system offering Bluetooth is a mobile application which allows users to access five in-car applications from cell phone: Bing, iheartradio, MovieTickets.com, OpenTable and Pandora. Entune provides mobile search, streaming music service, movie ticket and booking dinner reservation. Moreover, passengers can get the latest information, such as sport scores, fuel prices, weather and traffic conditions. The apps can be controlled by using the touch screen or voice commands.

Bluetooth will become one of the top trends in vehicle market because it allows a broad range of electronic devices to connect and communicate with in-vehicle infotainment system, such as mobile phones, MP3 players, PCs and tablets. We can see more companies are responding to customer demand and attaching this technique into product development to support the increasing demand of Bluetooth. The more Bluetooth products are available, the more validations on functionality and reliability are needed.

Case: In-vehicle Infotainment System V.S. Bluetooth Cell Phones

We are taking the condition of Bluetooth cell phones to connect with in-vehicle infotainment as an example. There are several points need to be cared:

Pairing and Connect

First thing is to make sure to pair and connect Bluetooth devices thoroughly, such as the ability to search for other Bluetooth devices or GAP (Generic Access Profile) support.

Contact information Transfer

For safety and convenience, it is common to allow users to import phone contacts into in-vehicle system. To ensure contact information is readable and updated correctly at the same time, we need to pay attention to several points, such as SAP (SIM Access Profile) connection, PBAP (Phone Book Access Profile) and OBEX (Object Push Profile) support.

Phone Function

To ensure in-vehicle system can operate basic phone functions through hands-free kit, such as calling and receiving calls, three-way or multi-way calling, disconnection and reconnection, call transfer and in-call audio quality.

Audio Streaming

Lately, users are commonly loading different formats of music files from cell phone to car music player, so the performance of audio streaming through Bluetooth plays an important role, such as A2DP (Advanced Audio Distribution Profile) functions, play/pause/stop/volume/speed functions and the stability of music files.

Performance

To ensure the quality of in-vehicle system, the performance test with other competitors’ products cannot be ignored. Thus, different Bluetooth devices of in-vehicle system have its own interoperability with each kind of cell phones under different temperatures, therefore, protential problems could be found under interoperability test.

Pairing and Connect
Contact information Transfer
Phone Function
Audio Streaming
Performance

To make driving experience more enjoyable and convenient, Bluetooth technology is almost a must-have application that is applied to many kinds of in-car devices. With years of research and product test experience, Allion is able to provide test solutions throughout your automobile electronics product development stages.

Top Leading Industry Standards (2): HDMI, DisplayPort and SATA

2011-04-14T02:40:00.001-07:00

In the second article, we will continue introducing the next three industry standards: HDMI, DisplayPort and SATA.

4. HDMI

＊HDMI Logo

HDMI (High Definition Multimedia Interface) is a digital interface standard for connecting all HD components. HDMI supports all video/audio formats by one single cable. The CEC allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with one remote control handset. HDMI technology is promoted by HDMI, LLC. According to HDMI Testing Policies, each Adopter must submit the first product of each Licensed Product type (i.e. source, sink, repeater, or cable) to an HDMI Authorized Testing Center (ATC) for testing. Once an Adopter product of each type has passed testing, it is not required to submit to the ATC subsequent products of that type. However, to help ensure HDMI interoperability, we encourage Adopters to use the ATCs.

＊Different Types of HDMI Logo

Due to the popularity of HDMI connector, there are a lot of fake HDMI products without testing, and illegally using HDMI logo on products or packages. This is not only a copyright violation to the association but also a threat to customers. Lately, HDMI is cooperating with Customs and Border Protection (CBP) to enforce the intellectual property and protect the Trademark symbol against illegal products, so vendors have to be sure that the logo is used correctly and legally after an authorized test.

5. DisplayPort

DisplayPort is a new digital display interface standard put forth by the Vide Electronics Standards Association (VESA); it would replace DVI, LVDS and VGA interface. It defines a digital audio/video interconnect intended to be used on PC field and CE field, DisplayPort Compliance Program is designed to ensure that products are standardized by physical layer and link layer test.

＊DisplayPort Logo

Compared to HDMI, DisplayPort not only provides different updated versions, but also develops various specifications, such as DOM, eDP and iDP. DDM (Direct Driver Monitor) simplified the peripheral design for Ultra Sleek Monitors; eDP (embedded DisplayPort) can output the signal through Graphic Processing Unit that reduces power consumption; iDP (internal DisplayPort) is designed for flat TV display interface to control the transmission between SOC and TCON, and its low battery destruction can reduce inner circuit configuration and power consumption.

6. SATA

＊SATA Logo

SATA (Serial Advanced Technology Attachment) is designed to replace the older PATA (Parallel ATA) interface; some technical improvements are including faster transmission speed, easier installation, improved system airflow and hot-plugging support.

Standardized specifications for the Serial ATA interface is defined and delivered by SATA-IO. Vendors have to pass the SATA Certified Logo Program in order to obtain the certified logos without exception.

Lately, SATA-IO has announced a new interface standard, which is called SATA USM (SATA Universal Storage Module), can combine with a variety of products without charging or extra cables, such as TVs, set-up boxes, playstations and computers. Vendors have to pass the certified program to receive the right to use SATA USM logo as well.

SATA-IO Certified Logo Program

To get certified logos through certified programs is the best way to protect product quality

As we observed above, these six popular logo programs are widely accepted in the market.In fact, we has accumulated test experiences of these technical standards for a few years; Allion is a global IT testing and verification consulting firm conducting interoperability, performance and compatibility testing services besides of standard certification for companies all over the world. Technology standardization is the foundation to help accelerate technology industry to innovate, and we believe, through certified programs and regulations would maintain product quality in any specifications.

We expect these two articles would make readers not only receive information in each technical standard, but also realize the significance of obtaining certified logo through certification process. Holding this reorganization would build up the level of technique in the whole industry, and also protect customer right at the same time.

Top Leading Industry Standards (1): Windows, USB and Wi-Fi

2011-04-14T02:33:00.001-07:00

Along with the fast-growing technology, technology standardization is not only promoting technology development but also providing a clear purchase direction to consumers.

According to today's market, Allion Test Labs has collected six top industry standards and specifications here below, which includes Microsoft Windows, USB, Wi-Fi, HDMI, DisplayPort and SATA. In the first article, we will introduce the first three industry standards.

1. Windows

＊ Windows Logo

WHQL (Windows Hardware Quality Labs) is a Microsoft procedure for certifying that the hardware for peripherals and other components is compatible with Microsoft Windows operating systems. Vendors have to pass this test to ensure its product quality before obtaining the“Designed for Windows”logo. In addition, the program allows vendors to leverage the worldwide awareness of the Windows brand through the use of the windows logo. That logo, on the vendor's product packaging, advertising or website, signals to customers that the product has been tested to verify that it meets Microsoft standards for compatibility with Windows.

The majority of vendors are familiar with the Windows Logo Program because the popularity of Windows operating systems in computer market. However, building a self-test platform is an obstacle because of a variety of testing ranges and updated versions. Moreover, the complex Windows logo testing process has become one of the biggest challenges while vendors are performing the test, so most of the time they would ask for a third-party laboratory to perform it.

Windows Logo Program includes reliability, functionality and specification tests. To reach a higher quality of Windows certified logo products, vendors could perform other verification tests to increase its product usability and market value through Allion, the third-party test lab.

2. USB

＊Common USB Logo

The majority of people are familiar with USB, Universal Serial BUS (USB) makes connecting computer peripherals easier by providing a standard serial cable connection, eliminating the need for add-in cards, setting DIP switches or changing IRQs. Printers, keyboards, pointing devices, networking devices, monitors, scanners, and tape drives are among the type of products that use the USB standard.

The USB Implementers Forum (USB-IF) is a non-profit organization formed to provide a support organization and forum for the advancement and adoption of Universal Serial Bus technology. To complement the specification and measurement of compliance in product space, the USB-IF has instituted a Compliance Program that provides reasonable measures of acceptability. Products that pass this level of acceptability are added to the Integrator's List and receive the rights of usage for the USB logo.

We have also included interoperability, embedded host TPL and electrical tests besides of USB-IF logo program. Recently, there are more venders to focus on the latest USB 3.0 specification in product development; therefore, the process of waiting for Platform Interoperability Lab (PIL) to test has become longer than before. Fortunately, Allion has been one of USB-IF Compliance Program testing labs to perform parts of USB 3.0 test categories, which helps accelerate time to market for USB 3.0 products for vendors.

Challenges of Porting Android: Hardware-Software Integration

2011-04-01T03:03:00.001-07:00

Along with the growing of technology, consumers are expecting to get multi-tasking mobile phones with wireless Internet and multimedia entertainment applications even more. According to numbers from research firm Canalys for the fourth quarter of 2010, Android owned 32.9% of the worldwide smartphone market compared with iOS, which held 16% of the market. Google’s Android operating system has been phenomenal to be compatible with Apple iPhone currently because its growth rate of the market share and the unit sales are going up rapidly.

Worldwide smart phone market–Market shares Q4 2010, Q4 2009

Source: Canalys estimates, 2011

Due to the fact that Android is an open-source software stack for mobile devices, free spaces of innovations are welcome to any industry player. However, its flexibility and limitlessness not only could build up the market share, but also could bring many possible risks, such as hardware/software integration.

Basically, there are five major components of the Android operating system, and the architecture of the software stack is designed to develop a unique software platform and its system. The five layers from bottom to top are Linux Kernel, Android Runtime, Library, Application Framework and Application.

* Android Structure by Google

Five Techniques of Android System Integration
To all manufacturers, the biggest challenge is to make its own products compatible with Android system individually. In addition, the compatibility between each technique and application is also extremely important. With years of product test experience, Allion has summarized five techniques of Android system integration here below:

SoC Optimization
The difficulty of developing an Android device is to combine its operating system with System-on-a-chip and any other new techniques and to ensure it works perfectly with each other. SoC is involved in many rendering engines, such as open-source software Dalvik Virtual Machine and WebKit. At this time, some common features can be implemented into integrated SoC platform in advance, such as Bluetooth and Internet; this process would reduce product integration time. However, what to remain and change depends on each vendor's need and its product features.

Linux Driver Porting
A plenty of drivers with different functions are needed to be implemented into Android steadily; those drivers could be different from component manufacturers, such as USB, PCI and Network drivers.

New Technology Adoption
Many new specification techniques are more widely used in mobile phone devices. For instance, NFC (Near Field Communication), which is supported by Android 2.3, is a set of short-range wireless technologies. Every programming language has to be implemented into Android in order to make any new technique work.

Low Power Consumption
Battery duration is always the top concern to consumers because a longer battery life makes life more convenient. The most important feature for developing a portable device is its battery life and the quality of battery, so users can connect to the Internet, watch videos and download music longer and quicker.

Higher performance
Even if all new techniques keep coming up, we still can't ignore the original performance on device but be more cautious in facing with unexpected conditions, such as maintain programming speed and deal with system overload under Android multi-tasking operating system.

We have collected the table here above to show common issue and possible root cause objectively; every detail in product development process cannot be ignored. As a third party test lab, we expect this information would be a useful reference. Product compatibility and validation tests are essential to find out problems and solve it in an early developing stage. We will keep providing the test-related reports shortly, please keep an eye on our Technical Direct.

Smart TV Revolution – the Combination of Humanity and Technology

2011-03-23T02:58:00.001-07:00

To overturn our stereotypes, Smart TV manufacturers have tried to build a bridge between traditional television set and contemporary computer. Smart TVs and Connected TVs were the most eye-catching home electronic products while Tablet PCs were the most outstanding consumer electronic products at CES 2011. Big and thin LCD screens are not the only features to make high-end TV products but more advanced features, such as integrated Internet capabilities and computing ability.

According to the world-famous market research and consulting firm DisplaySearch, the most recent report indicates that 21 % of global TV products which were sold in 2010 have Internet connectivity, and it is also predicted that smart TV shipment will reach up to 1.22 billion units in 2014. Obviously, Internet connection has already become the trend in future television market.

What exactly makes a TV“smart”? To help you better keep pace with the market, we have collected some stunning Smart TV brands that have showcased at CES 2011 here below.

Samsung: 3D is the Power of Smart TV

Samsung won 37 CES 2011 Innovation Awards and was one of the most aggressive manufacturers who spent a fortune on advertising their Smart TV products; one of the most compelling Smart TVs was a 75-inch 3D LED Smart TV, which is claimed to be the largest full HD 3D LED TV ever. Not just only about design, but also about its functionality such as Internet connectivity and a wide range offering of applications. Samsung also displayed some Blu-ray players and the lightest 3D glasses to provide an identical 3D viewing experience to the world.

LG: Make Life Smart and Simple –“LG Smart TVs”

At this time, the target market for LG Smart TVs is to consumers in all different age groups by providing easy-to-access functions and endless entertainment options. LG has reached a higher stage of 3D entertainment by inventing its easy, uncluttered Home Dashboard. Moreover, Magic Motion Remote Control keeps originally simple to operate the four main sections which include TV Live, Premium Content, TV Apps and Launcher Bar without a PC keyboard button. Additionally, the invention of Smart TV Upgrader can make normal TVs to have LG Smart TV functions. LG Smart TVs make cinema-quality 3D possible for viewers by adding theater-alike features, such as flicker-free picture and blur-free images.

↑ LG Home Dashboard and Magic Motion Remote Control

Sony: Believe in Television Redefined

TV redefined is not only Sony's sales pitch for this year, but also its development direction to open the gate of Smart TV market. Since Sony has a comprehensive cross-platform development in many different fields such as gaming, music, picture and technology, the quality of a new series of Sony Smart TVs have been improved a lot in both software and hardware aspects. Except for 3D content and Internet connectivity, Sony is launching its own video-on-demand and cloud-based digital music service Qriocity, and they also corporate with Discovery and IMAX in a 3D Internet TV program “3net.”

Other Spotlights: Vizio, Acer and Asus

The North America top one seller Vizio believes to give consumers affordable quality life, and Vizio emphasizes on VIA Plus products interaction which is mainly between cell phones and flat screen televisions. Plus, two of the biggest Taiwanese PC manufacturers, Acer and Asus, are taking a step into smart electronic products through cloud computing by inventing new product/ platform named “Clear.fi” and “WAVI Xtion.”

As we can see, Smart TV has become a new market in many technology fields. Every vendor is trying to break the original format of Smart TVs into expected styles individually; therefore, new product development is significant in the very early stages. The more Smart TV products are coming out, the more challenges manufacturers will need to face with. Apparently, the importance of product testing and validation cannot be ignored. We also believe, consumers' expectations will stimulate product technique to keep improving and growing to the next level. We will keep providing the latest trend reviews, please keep an eye on our Technical Direct.

Second USB 3.0 Host Controller Certified

2010-12-13T18:08:00.001-08:00

One of the fundamental principles of economics is that greater competition helps to drive down pricing. Well, we’ve got some great economic news for the SuperSpeed USB market: The USB Implementers ForumUSB Implementers Forum (USB-IF) has announced the second certified SuperSpeed USB host controller to pass USB testing certification: the FL1000 by Fresco Logic. This marks an important step in industry adoption of SuperSpeed USB solutions, and promises some major benefits for developers and consumers alike.

Having two certified host controllers helps create a competitive marketplace that ultimately delivers the best and most cost-efficient product to consumers. The NEC µPD720200 was the first host controller to pass SuperSpeed USB certification in September 2009. We can only expect that this latest release is the first trickle in a wave of SuperSpeed USB 3.0 host controller options.

“Certification of additional products supports second source alternatives and competitive ecosystems; the second certified USB 3.0 host controller builds upon the industry momentum for SuperSpeed USB, providing OEMs a crucial building block as they work to bring their SuperSpeed USB products to consumers worldwide,” said Jeff Ravencraft, USB-IF president, in a recent release. “We are pleased with Fresco Logic’s contribution to the SuperSpeed USB ecosystem with its certified host controller. Certification ensures the best experience for consumers, and we encourage all companies developing SuperSpeed USB products to seek certification.”

Certification demonstrates that a product complies with industry standards and shows that it will be interoperable with other devices currently on the market. With these certified host controllers, designers can develop external hard drives, SSDs, flash drives and computers to take advantage of SuperSpeed USB technology, while still being fully backward compatible with USB 2.0 products currently available. For more information on USB certification testing, testing for other industry standards, or for questions on designing end-products using SuperSpeed USB host controllers, contact Allion today.

PCIe 3.0 Released

2010-12-05T23:17:00.000-08:00

A few months ago, we wrote about the industry’s anticipation for the latest version of the PCI Express (PCIe) specification. Well, the wait is finally over: the PCI Special Interest Group (PCI-SIG) has officially released PCIe Base 3.0. These latest specifications are currently available for PCI-SIG members. As a provider of PCI express standards testing, Allion is excited to learn about the newest version of this technology.

The PCIe v3.0 architecture offers notable improvements over PCIe v2.0 and optimizes the trade-offs between manufacturability, cost, power, complexity, and compatibility. The update doubles the interconnect bandwidth, offering a 128-bit/130-encoding scheme and a data rate of 8 gigatransfers per second (GTps). With the data rate expansion, “It is possible for products designed to the PCIe 3.0 architecture to achieve bandwidth near 1 gigabyte per second (GB/s) in one direction on a single-lane (x1) configuration and scale to an aggregate approaching 32 GB/s on a sixteen-lane (x16) configuration,” according to Benchmark Reviews. PCIe v3.0 is fully backward compatible with previous PCIe architectures and is optimally designed for high-volume platform I/O implementations.

“Each new version of the PCIe spec has doubled the bandwidth of the prior generation,” said Nathan Brookwood, research fellow at Insight 64, in a press release. “The latest group of PCIe architects and designers drove the standard forward while maintaining complete backward compatibility for Gen 1 and Gen 2 devices. Rarely has a standard advanced so non-disruptively through three major evolutionary cycles. The ability to pull this off demonstrates not only the ingenuity of the Gen 3 developers, but also the insight of those who defined the earlier versions in such an extensible manner.”

We’re excited that the wait is over, and we look forward to helping developers deliver exciting new PCIe products with our PCI testing services.

Wi-Fi Alliance and HomePlug Powerline Alliance Join Forces for Smart Grid Interoperability

2010-11-21T23:33:00.001-08:00

The last few months have been filled with exciting announcements in the wireless space. From Wireless DisplayPort, to Direct Connect, to the opening of the airwaves for a new Wi-Fi Spectrum, the wireless industry is seeing a wave of movements promising great opportunities for developers. Now, the Wi-Fi Alliance and the HomePlug Powerline Alliance are bringing us a new cause for celebration. The organizations have announced that they are partnering to create joint standards, allowing for interoperability among connected home applications. These standards will also allow developers to conduct interoperability testing for new products.

This new partnership aims to facilitate seamless interoperability between Wi-Fi and HomePlug devices in smart grid applications across home networks. These organizations, both members of the Smart Grid Interoperability Panel (SGIP), are looking to promote Smart Energy 2 Applications Profile (SEP 2.0) across a diverse range of wireless and wired networks. This initial standard will support energy management for wired and wireless home networks. The organizations are planning to jointly promote their wired and wireless technologies to homeowners.

“Working with the HomePlug Powerline Alliance will facilitate interoperability between Wi-Fi equipment and devices connected to power line home networks,” said Edgar Figueroa, CEO of the Wi-Fi Alliance, in the recent release. “This collaboration will help bring about a great user experience with smart home technology.”

WiGig and VESA Team Up for Wireless DisplayPort

2010-11-11T18:14:00.000-08:00

Anyone who has ever set up an IT monitoring station or a living room entertainment system knows that cables can be a nuisance. Luckily, hope is on the way: The WiGig Alliance and Video Electronics Standards Association (VESA) are partnering to create wireless DisplayPort, which will allow users to connect high-definition display and audio systems without the use of cables.

This new technology, aimed at consumers and IT professionals, will allow users to connect devices such as PCs, handhelds, monitors, projectors and TVs without the use of wires. WiGig’s 60 GHz technology offers considerably more bandwidth than traditional 802.11n Wi-Fi, and provides bi-directional I/O capabilities to support the DisplayPort v1.2 feature set. This allows the same high-definition quality as a standard DisplayPort cord. WiGig and VESA are currently partnering to develop a certification program.

The WiGig Alliance has completed the 1.0 A/V and I/O protocol adaptation layer (PAL) specifications, which will be published early next year. The A/V PAL (WiGig Display Extension) supports wireless transmission of audio visual data, while the WiGig I/O PALs (WiGig Bus Extension and WiGig Serial Extension) define high-performance wireless implementations of widely used computer interfaces over 60 GHz. Together, these PALs enable multi-gigabit wireless connectivity between any two devices.

Wireless DisplayPort technology is expected to create a whole new class of interoperable wireless products, with the quality and performance of traditionally wired interfaces. We eagerly await the certification program, and look forward to creating a DisplayPort test for developers of new wireless display devices.

Direct Connect, Here We Come! Standards Compliance Testing for Wi-Fi Direct

2010-11-11T18:11:00.001-08:00

For times when Internet hotspots aren’t available, the Wi-Fi Alliance is now offering certification for a new way to connect: Wi-Fi Direct™. First demonstrated at CES 2010, Wi-Fi Direct enables devices to connect directly without relying on a network access point. Furthermore, Wi-Fi Direct allows users to share data and sync at the same speeds as traditional Wi-Fi networks – as fast as 250Mbps – and at ranges of up to 200 meters. The new certification program is designed to verify interoperability, and certified products will be able to connect with older Wi-Fi products already in use.

The Wi-Fi Alliance’s video, above, shows the many ways devices can take advantage of Wi-Fi Direct.

With several industry leaders – including Intel, Cisco and Apple – backing the technology, Wi-Fi Direct is expected to be adopted across a wide range of products, including cameras, laptops, smart phones, tables, printers and even home applications such as digital picture frames.

Allion is excited to announce our new role as an authorized test lab for Wi-Fi Direct. We have a long history of providing standards compliance testing services for manufacturers working with IEEE 802.11 benchmarks, and we are excited to begin Wi-Fi logo testing for Wi-Fi Direct.

“Allion is capable of verifying all Wi-Fi standards such as Wi-Fi 802.11 a/b/g/n and the latest Wi-Fi Direct,” said James Ou, director of Allion’s engineering service division in a recent press release. “Our goal is make the program simple for our customers and to accelerate time to market.”

Consumers are more connected than ever, with Wi-Fi enabled laptops and cell phones providing virtually seamless Internet access. Now analysts are saying that the next wave of networked-enabled devices will be your televisions.

According to a new report by DisplaySearch, sales of Internet-enabled TVs are expected to grow by more than 200 percent over the next four years. The Quarterly TV Design and Features Report forecasts that more than 118 million Internet-connected TVs will ship in 2014, a significant increase from the 15 million shipped in 2009. The growth of network-enabled TVs is expected to occur in conjunction with 3-D TV adoption.

“It’s an exciting time for the connected TV sector,” said Paul Gray, director of European TV research for DisplaySearch, in the report. “It’s a battleground where TV set makers, Internet video companies, free-to-air broadcasters, pay-TV and the IT industry are all rushing to stake their claims. IPTV [Internet Protocol Television] is moving from being a technology to becoming recognizable service offerings.”

The burgeoning IPTV industry offers plenty of options for designers looking to take advantage of new market opportunities. New service platforms are being developed, with connectivity levels ranging from app-enabled TVs – which allow users limited Internet services – to “Smart TVs” offering full browsing capabilities and sophisticated user interfaces. Meanwhile, broadcasters are launching their own standards and portals such as hbb.TV and YouView.

The demand for connected TVs follows the industry movement we have seen here at Allion. We’ve witnessed products become increasingly connected, with our product validation services enabling us to stay at the forefront of these emerging markets and trends. For questions on the challenges facing manufacturers in this sector or to start developing your personalized digital TV test, contact Allion today.

Consumers Eager for Wireless Charging, Despite Barriers

2010-11-11T18:07:00.000-08:00

Recently we wrote about the growing market opportunity for wireless charging devices. These products will allow customers to charge mobile devices –such as cell phones, laptops, MP3 players and more – simply by having them touching or within proximity of a shared charging station. Such devices would eliminate the plethora of cords required to power today’s digital gadgets. Furthermore, such wireless chargers could be integrated seamlessly into furniture and cars.

Consumers are more than eager for these types of products to enter the market; in fact recent In-Stat research found that consumers are becoming impatient for this technology to mature. With 44 percent of survey respondents calling current charging solutions an “annoyance” and up to 40 percent willing to pay $50 dollars more for a wireless charging device, In-Stat projects that that this market will reach $4.3 billion in total market revenue by 2014.

However, technological barriers are preventing immediate market growth. The variety of digital devices and brands makes interoperability testing a problem. Furthermore, competing technologies could foster incompatibility. Needless to say, consumers will not want to buy multiple wireless chargers for different devices. Without standardization, it could be difficult to achieve widespread adoption of wireless charging technologies.

Despite these obstacles, the wireless charging market has such great potential and natural consumer demand that we expect it to move forward. Manufacturers will not want to miss this opportunity to provide consumers with cutting-edge charging technologies. Allion will continue to provide more information as it becomes available, and we look forward to testing and validating this new wave of devices.

Happy Birthday, Wi-Fi n!

2010-10-13T00:45:00.000-07:00

One year ago the Wi-Fi Alliance launched its Wi-Fi CERTIFIED n compliance program, creating a certification process and logo for the IEEE 802.11n standard. Within that time frame, more than 1,100 products – from cellphones to TVs to enterprise-grade infrastructure devices – have been certified, and consumers have drastically changed the way they interact with electronics.

As we celebrate the anniversary of the certification, here are a few of the landmarks Wi-Fi CERTIFIED n has made in the last year:

127 phones have passed certification testing, reportedly accounting for 20 percent of handsets certified in the last 12 months.
251 consumer electronics products have been certified, including digital audio systems, gaming devices and displays.
441 of these certified products are dual-band products – capable of operating in both 2.4GHz and 5GHz frequency bands – and 143 products can support 2.4 GHz and 5GHz operation concurrently.157 enterprise-grade infrastructure devices and 115 enterprise-grade access points have been certified as enterprise networking vendors respond to growing demand for networking solutions.

This increase in connectivity has made a huge impact on the indus

try in short period of time. As a recent In-Stat report stated, Wi-Fi has achieved “ubiquity, a term often used but seldom realized in technology market-speak.” At Allion, we’ve seen this growth take place first hand, with our Wi-Fi Logo Testing Program – which includes 802.11n testing –

allowing us to support the Certified Wi-Fi rollout for both consumer and enterprise devices alike.

“It’s clear that Wi-Fi’s integration into virtually all areas of the consumer electronics spectrum continues to expand,” said Phil Solis, research

director, ABI Research in a recent Wi-Fi Alliance release. “At the heart of this growth is Wi-Fi CERTIFIED n, which will continue to deliver the

advanced performance these devices require, now and well into the future.”

So happy birthday, Wi-Fi CERTIFIED n! We’re excited to see what the next 12 months may bring.

PCIe 3.0 Here at Last: Welcome to the Future of PCI Testing

2010-10-13T00:41:00.000-07:00

The long-awaited PCI Express (PCIe) 3.0 specification standard is set to arrive in November, opening the doors for a new wave of products featuring faster interconnect speeds. Consumer products using the PCIe 3.0 are expected to arrive as early as the second half of next year.

The PCI Express 3.0 specification will define

operating speeds of up to 8 gigatransfers per second (GTps), delivering a significant boost from the 5 GTbps defined by PCIe 2.0. It also offers 128- and 130-bit encoding schemes, improving efficiency from the current 8- and 10-bit format and leaving nearly the entire bandwidth free for signal processing. Other new features include Dynamic Feedback Equalization (DFE), a sophisticated technique in electrical signaling designed to maintain signal integrity. The updated specification is expected to aid the growth of faster PCIe switches, 40Gbit Ethernet chips, high-end graphics cards, and solid-state drives (SSDs). PCIe 3.0 is fully backward compatible with previous generations of PCI technology. The chart below shows how the new standard compares to older PCI testing specifications.

PCI-SIG, the industry organization chartered to develop and manage the PCI standard, will issue tools to validate designs and start will launch interoperability testing workshops in mid-2011, with specification testing for PCIe 3.0 expected to be completed late next year. We will keep you posted on developments about this exciting specification update as they become available.

USB 3.0 and WiDi Make Waves at IDF

2010-09-20T20:48:00.000-07:00

Wireless Charging: A Whole New Market

2010-09-20T20:45:00.000-07:00

The average consumer uses a variety of electronic devices daily – cell phones, laptops, MP3 players, headsets, etc. – all of which require different chargers for keeping gadgets at full battery. In a market driven by mobility and convenience, charging solutions have failed to evolve with the rest of the industry. Not surprisingly, consumers have become annoyed with all these different, often proprietary, cords and connectors. According to recent surveys by In-Stat, approximately 44 percent of respondents found that “current mobile charging solutions are an annoyance,” and “up to 40 percent are willing to pay $50 more for a wireless charging solution.”

This is creating a new market opportunity for wireless charging systems. According to a recent study by In-Stat, the market for wireless charging systems will reach $4.3 billion in total revenue by 2010. These products can charge mobile devices, from phones to PCs to handsets, simply by having the devices touching or within the proximity of a charging station. These charging solutions can often be hidden, or at least seamlessly integrated, into furniture or automobiles; more than two thirds of the integrated charging solutions are expected to be in cars.

“Despite the long history of the various technologies, we are really just now beginning to see the true market potential for wireless charging solutions,” says Jim McGregor, In-Stat’s chief technology strategist. “Like many other technology markets, it will start with add-on and third-party solutions. Eventually solutions will be integrated into many mobile electronics as the costs decrease and the demand increases. While still a fraction of the overall mobile device segment, wireless charging is just beginning to hit its stride in the market.”

As with all technologies designed to service a variety of devices from different vendors, interoperability will be a primary challenge for product designers. Wireless products also face the added difficulty of avoiding interference with other wireless devices. Allion Test Labs will continue to track this industry trend and provide insight for manufacturers.

All roads lead to China

2010-08-31T19:20:00.000-07:00

* This article is written by Allion Japan office with the business vision and perspective towards the greater China region.

From around the world companies are heading to China. More and more Japanese companies are establishing joint ventures with local companies to get opportunities lying in this huge country. This penetration of the Chinese market is occurring in several domains. Indeed, many types of businesses are looking for new markets in China.

And this move is not an exception for the product verification (testing) market where Allion belongs. After a successful launch of a test lab in Shanghai, Allion just opened another test lab in Shenzhen in August. Shenzhen is known for having one of the highest GDP per capita among mainland Chinese cities. It is also a city home to China’s most successful IT companies.

Allion Shenzhen test lab is intended to respond to the huge demand of IT products quality control and development. The lab will provide HDMI, USB test and also RF signal test; as well as compatibility test between devices.

Nowadays more and more Japanese companies are forming joint ventures in China to move their production there. This leads what is called in Japan “hollowing out of domestic industry” caused by Japanese enterprises shifting production overseas to take advantage of lower labor costs. Many products nowadays are “Made in China”. HDMI LLC reported that Chinese companies make up more than 20% of companies adopting HDMI worldwide. In 2009 all digital TVs integrated HDMI. Being aware of these factors, Allion will also provide HDMI testing services at the Shenzhen lab.

Reverse –import is another factor related to

China

. Some Japanese companies produce overseas to import it back to their own country. It becomes then a necessity for companies testing (verifying) the quality of those products to also move to the countries where products are manufactured. As in the past when Japanese car manufacturers started to penetrate the

market, parts manufacturers had also to follow them and create companies in US to supply them car parts. The same move might be necessary for testing companies.

mSATA SSDs Capitalize on Budget Market

2010-08-27T04:01:00.000-07:00

With consumers looking to take advantage of the power and performance benefits of solid state drives (SSDs), several players have introduced product lines targeting value-conscious consumers. While some customers want the most powerful SSD money can buy, others are looking for a product that gives them the benefits of SSD without breaking the bank. For manufacturers looking to appeal to the more budget-conscious consumer, one option is designing SSDs using the mini-SATA, or mSATA, interface.

The Serial ATA International Organization (SATA-IO) announced last year that it was developing a specification for a mSATA interface connector, allowing for more effective SATA integration in small form factor applications. mSATA leverages the speed and reliability of the SATA interface, providing high-performance and cost-effective storage for smaller devices and enabling more compact integration into a wide variety of applications. As a result, companies can increase their storage and performance offerings without compromising on space.

mSATA SSDs are approximately the size of a business card and reside in a smaller PCI slot than standard SSDs. Instead of replacing a hard disk drive (HDD), mSATA-based SSDs work in conjunction with HDDs. For example, the computer can use the mSATA SSD for the OS and other primary functions, while the HDD stores the data, music and photos. Manufacturers such as Toshiba and SanDisk currently offer mSATA SSDs, and Intel is reported to be developing its own line.

“Initial adoption of most SATA solid state drives has followed the HDD form factor. Using new mSATA modules enable a smaller, internal module connected to the system board for notebooks, mobile and other embedded storage applications to enable designers greater design flexibility,” Scott Nelson, VP Memory, Toshiba America Electronic Components, said in the original press release.

No concrete timeline has been given for when the mSATA test specification will be available, but Allion has many years of experience with SATA testing and working with manufacturers through SSD development and validation, and looks forward to helping deploy mSATA-compliant products.

Solving the Challenges of Wireless Connectivity

2010-08-27T04:00:00.000-07:00

In today’s connected society, wireless connectivity is considered a given. From our cities to our state parks, wireless access has become ubiquitous. We can connect to the Internet via our laptops, our cell phones and even our televisions. Consumers expect that their electronics and devices will be wirelessly enabled. But what does that mean for developers?

Many designers do not anticipate the challenges of developing wireless-enabled devices. Whether in the product development,design validation or testing phase, complications with wireless implementation can have a serious impact on product development time. It is not uncommon to see 3-4 month delays. These delays result in increased development costs as engineers work to sort through the kinks in order to guarantee network interoperability. And with the number of wireless-enabled devices growing every day to meet the exploding demand for Wi-Fi enabled devices, more developers can expect to face the challenges of successful wireless implementation.

Fortunately, Allion Test Labs offers comprehensive product development, validation and testing services that can help manufacturers avoid these types of development mishaps. Allion has more than 20 years of validation service experience, offering our customers end-to-end support to ensure smooth product development. This result: faster development time, significant cost savings and, ultimately, a better product for consumers. By teaming with our engineers from the start, manufacturers can take advantage of this exploding market without risking development delays.

Falling Prices, Growing Demand for SuperSpeed USB

2010-08-27T03:59:00.000-07:00

With all the benefits of SuperSpeed USB (USB 3.0) – including faster speeds, bidirectional data interface and lower power consumption – consumers are eager to adopt this cutting-edge technology. Until this point, one of the main hurdles slowing widespread adoption has been the price of chips. However, NEC, the first company to ship a SuperSpeed USB host controller, is looking to change that. The company reportedly plans to significantly reduce prices for its first- and second-generation USB 3.0 chips later this year.

NEC’s third-generation USB chip models are scheduled to start shipping in Q1 2010, priced at less than $2. Other companies, including ASMedia (an Asus subsidiary), Etron, VIA and Fresco Logic, have all introduced price cuts for SuperSpeed USB products as well, with ASMedia dipping as low as $1.70 per chip for bulk orders.

Market watchers are predicting that 20 million SuperSpeed USB chips will ship by the end of the year, followed by 40 million shipments in 2011. With these dramatic price drops and a growing number of USB 3.0 certified devices, it’s likely that consumers won’t have to wait much longer for widespread adoption.

Lower prices and an increasing number of shipments mean manufacturers have the tools they need to take advantage of the demand for lower-cost SuperSpeed USB products. But despite the falling price of chips, developers still need to be aware of the costs associated with test development and product design validation. By pairing with a certified product development and testing company such as Allion, offering end-to-end validation solutions, developers can improve time-to-market and reduce overall costs, a savings which can then be passed on to consumers eagerly awaiting new SuperSpeed USB devices.

New DisplayPort Cable Adapter Certification Program

2010-08-27T03:57:00.000-07:00

The Video Electronics Standards Associate (VESA) recently introduced a new certification testing and DisplayPort Certified Logo for Dual-mode DisplayPort cable adaptors. These dual-mode cable adaptors allow for seamless interoperability between a Dual-mode DisplayPort PC or graphics card and a DVI monitor or HDMI TV. The certification program was designed to help customers identify cable adaptors that have been thoroughly tested and certified for proper functionality with other DisplayPort products through the use of a distinctive logo and product packaging.

The DisplayPort standard, developed as a replacement for digital (DVI) and analog component video (VGA) connectors, uses simple adaptors to provide interoperability with DVI, HDMI and VGA displays. When plugged into a Dual-mode DisplayPort PC or graphics card, these adaptors can output either Single Link DVI or HDMI signaling. Almost all DisplayPort PCs with integrated graphics or discrete Graphics Processing Units (GPUs) have Dual-mode DisplayPort capabilities.

Certification testing is available for both DisplayPort-to-HDMI and DisplayPort-to-DVI Dual-mode cable adaptors. Dual-mode DisplayPort cable adaptor certification and testing follow the DisplayPort Interoperability Guideline Adaptor Checklist. The checklist was designed to help developers ensure display interoperability and achieve adapter certification. Allion Testing Labs in Taiwan is certified to offer Dual-mode DisplayPort adapter certification testing for both VESA members and non-members for a nominal fee. Once a product passes certification testing, a logo license agreement is available through VESA at no cost for VESA member companies and for $1500 USD for non-members.

For engineers, this certification program represents a new opportunity to distinguish your product. Thorough testing and validation, such as industry standard certification, helps ensure product quality; this can save manufacturers from the high cost and headache of managing customer complaints and merchandise returns. And by choosing a certified testing lab with full engineering support and services, developers can produce the highest quality product while significantly reducing cost and time-to-market.

The Key to Google TV and its Verification

2010-08-02T19:42:00.000-07:00

Being one of the most anticipated high-tech gadgets for this year, “Google TV” is no longer a visionary invention. It has finally made its debut appearance at the Google I/O Convention earlier in May. Google TV is an integrated system which comprises the functions of a PC, Media Player and Internet Device all in one. While most of the details are yet to be released (including the SDK – Software Development Kit), the actual product will not be shipped until the end of this year. Nonetheless, through previewing its design structures we should be able to forecast how Google TV will withstand market competitions with its breakthrough design concepts:

First, let’s take a look at Google TV’s concept in design structures:

Google TV is built upon the structure of complex Hardware, Software, Technology Standards (Specifications), and Content Resources. The combination of each structure needs to work seamlessly to achieve optimum performance; the compatibility and interoperability of each device or element must therefore become critical and essential.

Hardware

Google TV’s core structure is built upon multiple hardware devices as the operating environment; therefore, the interoperability among the connecting devices becomes significant. For example, an Android mobile phone, wireless keyboard and a mouse can all be connected to a Google TV. It is the manufacturers’ responsibility to make sure that all devices can be connected properly and operable on the Google TV platform.

Software

Google TV adopts its own Android and Chrome as its primary Operating System and Search Engine. With its strong intention to replace the functions of a PC, some of key checkpoints such as OS stability, application multitasking, and the friendliness to switch between a PC and TV should be thoroughly tested. The biggest challenge will remain with the release of the SDK, when a large quantity of software starts to emerge. Application testing procedures will become the key factor in determining its success.

Technology Standards

Many of the leading industry standards in wired and wireless connecting technologies are specified in the Google TV devices (i.e. HDMI, DisplayPort, Wi-Fi, Bluetooth, DLNA and more). Google TV is also designed to support the playback of cutting edge video and audio in high resolution. Whether it be in 3D Graphics, MPEG4 Streaming or the proper decoding of HDCP, meeting the basic compliance test guidelines to achieve its compliance certificate should all be the minimum requirement during the QA stage.

Content Resources

Finally, streaming content should be able to be downloaded, decoded and played back smoothly at the specified quality level. The content providers such as Hulu, YouTube and others should endeavor to streamline the test procedure in order to maintain the program and broadcasting quality.

An innovative product without quality will only remain visionary. To many people, Google TV is the first step for a PC and TV to finally integrate as one into our living room. Unlike many transitional products in the past, the Google TV adopts leading edge technologies and is aiming to revolutionize the way people watch and utilize television. It will only be meaningful when each and every feature can impeccably work to prove that Google TV is not just another flash in the pan product.

UPnP and DLNA Poised for Growth

2010-07-27T21:13:00.000-07:00

According to recent research by In-Stat, Windows 7 is expected to jump start consumer adoption of Universal Plug and Play(UPnP) and Digital Living Network Alliance (DLNA) technology. DLNA will see more than a billion units shipped by 2014, a significant increase from the few hundred million units shipped in 2009, with UPnP shipments slightly exceeding DLNA shipments.

The UPnP standard was designed to ensure interoperability among devices from different manufacturers. Building on the UPnP standard, DLNA is a set of guidelines for how to connect PCs and other consumer electronics in the home; for example, DLNA-enabled devices allow consumers to view their computer files on their HDTV. The DLNA guidelines specify the UPnP standard as the connection that all DLNA-certified devices have to use.

Windows 7 not only supports DLNA, but also requires that peripheral devices – such as HDTVs, Xbox 360s, electronic picture frames, etc. – be DLNA-certified to be listed as Windows 7 compatible. Currently, many consumers do not realize their PCs have these interconnection capabilities. As awareness of these capabilities increases, DLNA and UPnP adoption and sales are expected to grow significantly.

DLNA-enabled handsets, PCs and digital televisions are poised to see the most widespread adoption, accounting for 74 percent of the 2014 DLNA market.
More than 85 million DLNA-enabled Blu-Ray players and recorders are projected to ship in 2014.
Digital media controllers, which currently make up the smallest volume of UPnP shipments, will account for the largest growth.

This growth in adoption presents an enormous opportunity for manufacturers, but the array of consumer devices on the market can make verifying interoperability a challenge. Allion has established its Ecosystem Validation program to help manufacturers with product development; this validation tests a product with a complete line of digital products to ensure that it will function properly when a consumer brings it home. With interoperability a critical attribute for today’s consumer electronics, ecosystem validation can help developers ensure that their products will function properly in any home network.

VESA Releases Updated Embedded DisplayPort Standard

2010-07-13T20:06:00.000-07:00

The Video Electronics Standards Association (VESA) has issued the latest version of the Embedded DisplayPort (eDP) standard. eDP version 1.2 offers several enhancements to the original standard release, including increased simplicity and improved performance capabilities. Notebook PCs using the new eDP standard will begin production the first half of 2011.

Major updates in the eDP standard include cable simplification, reduced system power consumption, new display capabilities, 5.4Gbps link rate option and simplified PC chip integration. By lowering the number of required internal cables and interconnect signals, the eDP notebook panels offer simplified internal cabling and significantly reduced power consumption. A bidirectional AUX Channel further reduces the wire count while adding new LCD panel control and backlight capabilities, including dynamic backlight control, dithering, modulation frequency control and more. Data bandwidth for video data channels has also been doubled with support for the 5.4Gbps link rate defined by DisplayPort v1.2. This increased link rate allows for either fewer wires or full HD resolution of higher performance 2D or stereo 3D displays. Finally, eDP’s use of low-voltage, AC-coupled signaling is compatible with today’s sub-micron chip processes, simplifying overall design and reducing the required number of device pins.

eDP v1.2 is another step towards eDP’s eventual replacement of the Low Voltage Differential Signaling (LVDS). Notebooks featuring the eDP v1 interface, which began entering the market this year, will account for 11 percent of the 2010 PC market. eDP is projected to largely replace LVDS by 2013.

The eDP v1.2 standard is free of charge to VESA member companies. Non-member companies can purchase the standard through the VESA website.

Apple’s Avoidable iPhone 4 Problem

2010-07-05T11:43:00.000-07:00

Here at Allion, a company dedicated to product design, validation and testing, it’s always difficult to watch when product defects aren’t discovered until after the product enters the market. Unfortunately, that is exactly what happened to Apple: Shortly after the iPhone 4 made its stunning entrance on the consumer market, stories began emerging of problems with the iPhone’s antenna.

The iPhone’s revolutionary external stainless steel antenna system – one half dedicated to Bluetooth, Wi-Fi and GPS, the other half to UMTS and GSM – is separated by a small black line. Consumers have found that when they hold the phone with their left hand, which most right-handed people are likely to do, their hand can bridge the two antennas, causing the phone to lose reception.

Now, Apple did field test the iPhone 4 prior to launch. However, the prototype phones, made famous by the lost phone picked up by Gizmodo months before the phone’s official unveiling, all had a plastic cover to make them look like a standard iPhone 3; this cover may have prevented Apple from uncovering the problem prior to launch. The lab tests of the antenna were also successful, but they only accounted for the presence of a user’s head, not hands. Apple says that the problem can easily be fixed either by readjusting your hand position or purchasing an iPhone case, but many users are still concerned that the design didn’t take into account real-world use.

Fortunately, these types of design errors are avoidable. Third-party testing can help to uncover the flaws that in-house testing can miss, and also help in the redesign process. The process can not only improve product quality, but also speed development time; manufacturers enjoy faster time-to-market and a product that has been thoroughly validated, and customers receive a product free of defects. This testing can help protect a product’s image from a preventable problem.

Real World Interoperability Testing

2010-06-29T02:05:00.000-07:00

Interoperability testing is a vital step in the manufacturing process. The growing variety of brands, interfaces, standards and electronic functions make it a challenge for manufacturers to ensure that their product will be compatible with other devices. To verify that a product is fully interoperable, manufacturers need to thoroughly test it using a range of real world consumer devices.

Using real world electronics instead of lab simulations provides a more accurate portrait of how a device will function once it enters the market. Testing a product using a variety of devices can help account for the variations between different regions and brands. For example, a product that is only tested and verified in the United States may not be fully compatible with products and regional standards in Japan. Without proper testing, a product may encounter several errors: Product functions may not work, audio and video may be out of sync, or the device may simply be undetectable. For consumers, encountering incompatible products can cause product malfunction and headaches, all while damaging a brand’s image.

Part of the success of Allion’s interoperability testing is the variety of devices we use for product testing. Our comprehensive compatibility testing methodology compiles more than 1,300 consumer devices from all major world markets, including the U.S., Japan, Europe, China and Taiwan. This quarterly-updated list of devices is then ranked using a series of selection criteria, including sales ranking, satisfaction ranking and features, helping to maximize efficiency and streamline the interoperability and validation process. For example, our USB Interoperability Testing verifies a product using 75 camcorders, 322 cameras, 160 keyboards and computer mice, 88 card readers, 243 storage devices, 131 media players and 45 hubs. The results of testing help Allion guide manufacturers to identify and address factors that might prevent full interoperability. The result is a truly interoperable product, regardless of specification or region.

For more information regarding Allion interoperability services, view our Real World Consumer Electronic Interoperability Testing presentation slides from last month’s HD Test Solution Seminar & Plugfest.

TV Broadcasting Signal Test for Brazil

2010-06-01T03:15:00.000-07:00

Brazil has the largest television audience in South America, spurred by the increased buying power and financial leniency stimulating Brazil’s economy. In a 2007 effort to democratize communications and promote the development of local technologies, the Brazilian government began implementing digital broadcast systems in Brasilia, Brazil’s capital city, and 16 other major cities in Brazil. Current estimates are that the transition from analog to digital broadcast will be completed by the year 2016.

According to a recent study by DisplaySearch, consumer demand for televisions in Brazil experiences a surge every four years, correlating with the FIFA World Cup. With the 2010 FIFA World Cup and 2016 Summer Olympics both being held in Brazil, the government is capitalizing on the increased demand; Brazil will soon mandate that all TVs sold in the country include a pre-installed digital tuner. This mandate will be essential in popularizing digital TV and making Brazil the dominant television market in South America.

While Brazil’s growing demand for televisions presents several opportunities for television manufacturers, geographical limitations make actual TV field testing a challenge. Flying to Brazil from any region in Asia requires almost a full day of travel, and manufacturers need to take into account the unfamiliarity of local cities and cultures, as well as the language barriers the field engineers will face. And yet, without thorough testing, manufacturers cannot guarantee that their products will be fully compatible with the broadcasting signals used throughout Brazil.

To accommodate the rising demand to test televisions against the various broadcasting signals used in Brazil, Allion has returned with a series of TV RF signals, including ISDB-T and PAL-M, recorded in all of Brazil’s major cities (updated April 2010). Acknowledged by most leading TV developers, Allion’s Brazilian Real World TV Validation is a revolutionary testing method delivering proven efficiency and results; manufacturers can assess and guarantee television compatibility across multiple regions without having to physically fly engineers and televisions to Brazil.

VESA Issues Internal DisplayPort Standard for Flat Panel TVs

2010-05-27T10:12:00.000-07:00

The Video Electronics Standards Association (VESA) recently issued the Internal DisplayPort (iDP) interface standard to enhance inside-the-box connectivity for flat panel TVs. Based on the DisplayPort 1.2 standard, iDP is designed to replace Low Voltage Differential Signaling (LVDS) by using a simpler and higher-performing connectivity technology.

The VESA iDP standard addresses the connection between a TV controller system-on-chip (SOC) and a TV panel Timing Controller (TCON) within a TV chassis. With only 17 signals, eight differential pairs and one Hot Plug Detect (HPD) signal, the iDP link transports Full HD 240Hz at 10 bits per color, compared to the 96 signal requirement of LVDS. It provides optimizations specific for internal flat panel TV applications, similar to the VESA Embedded DisplayPort (eDP) interface standard used for the internal displays within notebooks and other PC devices.

The standard’s scalability allows iDP to support future design needs. For example, an iDP 1080p 3D implementation requires only two banks of 16 differential pairs and one HPD for 65 signals, compared to the 192 differential pairs that an LVDS implementation would require. iDP also eliminates the many LVDS printed circuit board traces and device pins, reducing system form factor and cost as well as lowering the shielding requirement by reducing electromagnetic interference (EMI). The standard is fully open and royalty-free, allowing for healthy competition among component suppliers, encouraging innovation with manufacturers and reducing costs for consumers.

“Today’s flat panel TV manufacturers are in a constant race to provide better picture quality, more realistic animation, and even 3D video. This continues to push refresh rates higher and has created the need for a new high-speed panel interface standard. VESA’s iDP standard meets that need while also helping control costs,” said VESA Executive Director Bill Lempesis in VESA’s May press release.

The X25-V features 40GB of 32nm multi-level cell (MLC) NAND flash memory and is capable of running up to 32 concurrent operations at nearly four times the speed of a 7200RPM hard drive. Consumers can download the Intel SSD Toolbox, complete with the Intel SSD Optimizer, to easily maintain SSD performance. The X25-V is a significant price drop from other Intel SSD drives, with an 80GB Intel X25-M available for $265 or a 32GB Intel X25-E starting around $380.
Desktop PC users will be able to add an SSD option to a dual-drive set-up, or “boot drive.” The Intel X25-V SSD, loaded with the operating system and favorite applications, is added to the a desktop’s dual-drive configuration with an existing HDD. The SSD allows for faster start time, while the “bootstrapped” HDD drive, or boot drive, serves as a means of higher capacity data storage.
The Intel X25-V is consistent with Intel’s latest strategy to bring SSDs “out of the niche markets and into the mainstream.” With the prices of SSD technology continuing to drop, it looks as though that goal might be well on its way to being fulfilled.

Increasing Automotive Complexity Requires Careful Planning and Execution

2010-03-07T23:17:00.000-08:00

Like so much of today’s technology, in-car technology has evolved at a rapid rate. Modern in-car networks have developed to support not only basic vehicle functions, but also entertainment and navigation systems.

Controller Area Network (CAN). The primary in-car network serial bus in today’s cars is the Controller Area Network (CAN). Originally developed in 1985 by Bosch, CAN remains the international standard for in-car networking. CAN utilizes twisted wire pairs to reduce wiring complexity, weight and cost while providing a reliable solution in high-interference environments. CAN also is able to operate at data speeds up to 1 Mbps, with High-speed CAN used for engine management and brake control and Low-speed CAN used for window and seat operations.

Location Interconnect Network (LIN). When CAN’s versatility and bandwidth is not needed, LIN offers a cost-effective, low-speed serial bus within the CAN network. Requiring only a single wire for physical implementation, LINs allow in-car connection and communication between intelligent sensors and actuators.

FlexRay. This newest vehicle bus standard was designed to be faster and more reliable than CAN. Developed by BMW and DaimlerChrysler for use in drive-by-wire systems, FlexRay offers deterministic and fault-tolerant data transmission with a bandwidth of up to 10 Mbps.

Media Oriented Systems Transport (MOST). MOST is the in-car bus standard for interconnecting multimedia components. MOST, which addresses the increasing popularity of in-car entertainment, navigation and telecom systems, has a maximum data rate of 50 Mbps; future generations are expected to reach 150 Mbps.

USB. Finally, USB technology, which has become ubiquitous on PCs and devices, has also made its way into the automobile. Devices are now being connected in vehicles via USB, allowing for “plug-n-play” capability among a wide variety of media players and devices that consumers expect to utilize in their automobiles.

Modern automobile network architecture has become increasingly complex, increasing the need for reliable vehicle bus standards and performance testing. The number of buses and protocols will increase as our entertainment and system needs grow, and the speed of innovation will continue to require updated and improved standards. The Allion Connect Certification Program ensures reliable connectivity between consumer electronics devices and automobiles.

Allion Puts LG Monitors to the Test

2010-03-07T23:14:00.000-08:00

Allion recently had the opportunity to test the LG Network Monitor , a low-cost solution allowing multiple users to virtually share a PC. The LG monitors were put through a rigorous battery of tests designed to evaluate their performance and compatibility. The results were impressive.
The LG computer monitors first went through the Windows Compatibility Test. Ten monitors were connected to a computer running Microsoft Windows to evaluate their compatibility with the operating system as well as their performance when running multiple applications simultaneously.
The second test performed was the Software Compatibility Test, a “multitasking test” in which various programs ranging from Microsoft Word to professional graphic design software are run simultaneously.
The final test, the Performance Test, measured the frames per second being displayed, examining for any lag or delay in the interconnected monitor installation. Final results exceeded expectations for overall performance and stability. All tests were passed at 90 percent or higher, with several, including the Device Enumeration Test and Power Management Test, passing with 100 percent compatibility. The tests demonstrated the monitors’ exceptional performance under the most demanding circumstances.
LG, in partnership with Allion, produced the accompanying video to document the rigorous nature of Allion’s display test services.

Intel Reveals Strategy to Lead SSD Market

2010-03-01T04:01:00.002-08:00

Intel aims to be the worldwide leader in the solid state drive (SSD) market. The company plans to unseat Samsung as the top market player while bringing SSDs to the forefront. In the SSD retail market, Intel currently claims the lead in the U.S. and sits second worldwide.

Intel’s joint venture with Micron Technologies Inc. has rolled out the first in a family of 25-nm devices, which, in addition to putting Intel almost a year ahead of the competition in terms of technology, gives Intel a significant cost advantage; while 34-nm competitors have an average cost of $1/GB, Intel’s 25-nm NAND part will average $0.50/GB. Intel plans to ship its new line of 25-nm device-based SSDs later this year.

“We want to be a leader in SSDs,” Tom Rampone, the VP and general manager of Intel’s NAND Solutions Group, told EE Times at a recent event. “We want to bring SSDs out of the niche markets and into the mainstream.”

Compelling SSD features, including unprecedented speeds, durability, and silent operation, will bring big benefits to end-users in both personal and enterprise applications. Also noteworthy is that SSDs enable new technologies such as SuperSpeed USB (USB 3.0) to achieve higher data transfer rates than what is possible with traditional HDDs. As we reported earlier this year, 2010 is shaping up to be the year for SSDs.

Crucial RealSSD C300: It's Fast

2010-03-01T04:01:00.001-08:00

After months of screen shots, pre-release videos and an appearance at CES, the Crucial RealSSD C300, announced in December, is nearing its public debut.

Sold and distributed by Micron’s retail branch, Crucial, the C300 uses Micron’s firmware and Marvell’s new SATA6Gb/s solid-state drive (SSD) controller to reach new levels of speed and performance. It is the first SSD to use ONFI 2.1 NAND flash memory, which offers performance of up to 200MB/s while enhancing power management. The C300 will be the industry’s fastest solid-state drive (SSD) for notebooks and desktop PCS.

TweakTown performed a series of SSD tests on the Crucial RealSSD C300 to see how its performance held up to the competition. Using PCMark Vantage, a hardware performance benchmark, to measure and compare performance, they found the C300 far outperformed the other drives on the market. For instance, during gaming the C300 was able to run 201.26MB/s, while the 100GB RunCore Pro V came in second with 154.42MB/s. The C300 ran Windows Media Center at 261.40 MB/s, with the runner up performing at 190.75MB/s. The only exception was its abnormally low performance when running Windows Media Player, which testers believe is likely due to a firmware glitch. After zooming through all the tests, without the chance to idle, the C300 showed no significant decrease in performance.

With its improved reliability, lower power consumption and blazing speeds, the C300 offers a new level of computing performance. As TweakTown put it, “At this point in time, there is no other drive, platter or solid state that is in the same league as the Crucial RealSSD C300.” The C300 will be ready for consumers later month. The 125GB model will be available for $499 and the 256GB for $799.

DisplayPort 1.2 Opens New Data Opportunities

2010-03-01T04:00:00.000-08:00

As we recently highlighted, Video Electronics Standards Association (VESA) formally unveiled the eagerly awaited DisplayPort v1.2 specification. This new extension offers a number of new features: in addition to doubling the data rate and providing multi-streaming capabilities, DisplayPort v1.2 has the ability to transfer audio, video, USB, Ethernet, power, and data from multi-touch panels, cameras, microphones and more. By supporting a wide range of data through a single cable, DisplayPort continues to trend toward a unified interconnect and creates opportunities for manufacturers and consumers.

DisplayPort v1.2 data-supporting capabilities create a more simplified interface while increasing performance and reducing costs. The ability to transfer USB and Ethernet data will allow users to connect their monitor via DisplayPort and utilize the same cable to carry USB signals to the display, significantly reducing cable clutter and creating a simplified user experience. DisplayPort will allow manufacturers to add features to their products while creating simpler designs.

Additionally, the increased throughput of DisplayPort 1.2, which has an aggregate data rate of 17.28 Gbps, greatly improves performance by allowing for faster refresh rates of 120 Hz and, in turn, increased color depth, higher resolutions, and support for 3D gaming. DisplayPort’s energy efficiency as well as its ability to eliminate redundant cables reduces the interface’s energy consumption and costs. In-Stat projected that DisplayPort will see 194 percent annual growth in 2010, due primarily to the growing adoption of mobile PCs and to DisplayPort’s low power consumption.

The DisplayPort standard continues to gain traction in the industry and create opportunities for application development. VESA’s executive director Bill Lempesis has called DisplayPort the “standard of choice across the industry.”

VESA Unveils DisplayPort v1.2

2010-01-31T23:16:00.001-08:00

Video Electronics Standards Association (VESA) has finalized the long awaited DisplayPort v1.2 specification, offering improved performance and a multitude of new features. DisplayPort v1.2, which doubles the transfer rate from the version 1.1 specification from 10.8Gbps to 21.6Gbps, is paving the way for higher performance, faster refresh rates, and 3D stereo display.
Among the new features offered by v1.2 is multi-streaming, allowing users to connect up to four 1920×1200 monitors in a daisy chain or hub configuration while supporting protected content and high performance applications. It can also support bi-directional data transfer, allowing multiple independent, uncompressed data streams, such as USB hubs, video signals, and touch screen panels, to travel over the same cable at up to 720Mbps. DisplayPort v1.2 is backward compatible with DisplayPort v1.1a systems, including existing cables and also the Mini DisplayPort connector.
Keeping up with the 3D bandwagon, v1.2 has improved support for Full HD 3D Stereoscopic displays.

New RF Stream Technology Reveals Compatibility Issues

2010-01-31T23:14:00.001-08:00

Using the new RF stream recording technology, Allion designed a test to assess the level of television compatibility in the United States. RF signals were collected from 11 cities: Baltimore, Chicago, Dallas, Elgin, Englewood, Fargo, Los Angeles, Milwaukee, Minot, Newark and Philadelphia.
We chose three major TVs sold in North America that support the ATSC system:
Sony LC-32GP1U
Samsung KDL-32L4000
Sharp LN-Y3253H
Allion’s RF Stream TestsFor the testing, Allion sent the variety of RF signals collected to the TVs, and once the stream was received, we performed a series of checks to assess performance. We scanned all TV streams to verify that the streams were being recognized, while adjusting the intensity of the signal to determine the TVs’ sensitivity. We verified the audio and video quality, as well as audio/video synchronization. For stream data performance, we verified the display functions, including the channel and program title, caption service, aspect ratio and EPG information.
Our FindingsWhile the Sony had better overall performance than the Samsung and Sharp, we found compatibility problems across the board. The errors we found included mosaic pictures, double subtitles, scrambled text and broken images. Regarding the locales tested, Philadelphia had more failure than other cities, while Milwaukee had 100 percent performance from all three brands.
This case study demonstrates that even major TV brands can face compatibility issues. The field testing that TVs undergo prior to going to market is insufficient to guarantee consistent quality when receiving signals from different regions or countries. By offering a data pool of signals, Allion’s Real World TV Validation testing helps locate and prevent all possible compatibility issues.

New RF Stream Technology Revolutionizing TV Testing

2010-01-31T23:12:00.000-08:00

For TV manufacturers, sustaining the claim of product quality is vital to success; however, the industry has had difficulty consistently delivering on the claim. Broadcasting systems in different countries and regions produce different RF signals, resulting in high error rates. Even well-known TV brands can have compatibility issues when receiving signals in different regions.
While field tests have the potential to reduce error rates, they have intrinsic limitations. Successful field testing in one region does not guarantee that the product will work in nearby areas. Field testing also requires the manufacturers to heavily invest both time and money.
A new way of recording RF stream is revolutionizing how TV manufacturers solve the problem of addressing compatibility with differing RF signals. These RF signals enable developers to test their products by simulating the RF signals from different regions. The TV RF signals can be recorded and saved as the IQ format (TV RF Raw Data), containing the environmental factors and retaining complete parameter data.
The IQ format improves on the previously used TS (Transport Stream) format, where the demodulator reconstructed the signal but lost some of the related features during the process. With this new technology, TV manufacturers will be able to thoroughly test the tuner performance, A/V performance and stream data performance of their products without the high cost of field testing.
Utilizing the new RF Stream recording technology will make it possible for manufacturers to develop products that can live up to their quality claims in any region.

DisplayPort and USB 3.0 Named Among Top Technologies of 2010

2010-01-11T18:02:00.000-08:00

December 17th, 2009
Earlier this quarter, Maximum PC compiled a list of top technologies in 2010. We think this list is worth sharing as it gives some insight into where the industry is headed which will influence the test, validation and certification ecosystem. Several technologies we regularly cover on the Blog including USB, PCI, SATA and DisplayPort are listed. We think this is a good indication that many emerging technologies are poised to make a big splash both within the industry and with consumers next year.

Maximum PC’s full list of top 2010 technologies includes:

Intel Core i7 chip going mainstream – Intel’s new series of CPUs are affordable yet appealing to power users
AMD Orochi chip – the next generation chip can be built on the 32nm processor, rather than the current 45 mn process. This processor will feature more than four cores, over 8 MB of L3 cache and a DDR3 integrated memory controller.
PCI Express 3.0 – significantly increases bandwidth and efficiency over the existing PCIe 2.0.
Graphics - graphics chips from industry leaders such as NVIDIA and AMD will be fast and functional
Storage - hard drives will continue to become more spacious, fast and affordable
As we mentioned earlier this month, SATA Revision 3.0 (SATA 6 Gb/s) will give SSDs the throughput they need to optimize speed.
Mobile Broadband – WiMAX is a 4G solution for handheld devices and notebooks and will help bring broadband to rural area. Another 4G technology is LTE (long term evolution), an IP-based, low latency network with bandwidth 2-3x what WiMAX offers.
SuperSpeed USB (USB 3.0) - up to 10x faster than USB 2.0, backward compatible with Hi-Speed USB (USB 2.0) and optimized for power. Need we say more? We’re looking forward to testing SuperSpeed products as adoption becomes widespread.
DisplayPort – this digital display connection has been gaining momentum and will continue to grow in 2010. It is a DVI replacement and is significant as the connector is small and easy to use. DisplayPort provides more data per wire than DVI, and supports HDCP content protection. Allion is the leading independent test lab accredited by VESA for DisplayPort testing and plans to continue DisplayPort compliance and logo program testing as adoption for the standard expands next year.
Multi-touch – From gaming systems to computers to handheld devices, advanced touch technology will continue to be sought after in 2010.
Multiscreen – AMD has a high-end graphics card that can support up to six DisplayPort connectors. In a California test lab, each connector was attached to a 30-inch display, and the six monitors were configured as a single monitor.
While the list is extensive it is certainly not exhaustive, so which technologies do you think will generate the most buzz in 2010? Let us know in the comments.

First SSD to Use SATA 6Gb/s Link Announced

2009-12-16T17:54:00.000-08:00

Micron Technology released the new RealSSD C300 – the fastest SSD for notebook and desktop PCs to date and the first solid-state drive (SSD) to comply with the SATA Revision 3.0 (SATA 6Gb/s) specification. A 6Gb/s SATA link will help address the throughput bottleneck that today’s solid state drives face, making SSDs one of the major markets that benefit from SATA 6Gb/s. The move from SATA 2.0 to SATA 3.0 doubles the speed of link available to the SSDs. The Micron SSD will theoretically provide read speeds up to 355MB/sec and write speeds of up to 215 MB/sec.
So what makes these high speeds compelling?
New SSD options now available to consumers enable users to enjoy a better computing experience, from a faster OS boot times to quicker application loading, data transfer and file copying. There are many benefits to be gained by making the transition to SSDs. The video below provides a demonstration of advantages achieved when using Micron’s RealSSD C300 drive versus a hard disk drive (HDD).
Comparison of the Micron C300 SSD vs. HDD

The SSDs will be available in 1.8 inch and 2.5 inch form factors and in 128 GB and 256 GB sizes. Micron is sampling the C300 SSD in limited qualities and plans to enter production in Q1 of 2010.
Early in the development of the SATA Revision 3.0 specification, SATA-IO collaborated with test equipment companies to review testing parameters. Test platforms operating at the margin of SATA 3Gb/s will likely fail if they are not updated to meet SATA 6Gb/s requirements. SATA 6Gb/s compliance and certification will be needed to ensure interoperability in the SATA ecosystem.

Google Chrome OS Detailed for Industry

2009-12-07T19:50:00.000-08:00

Last week, Google held a small event at their headquarters and outlined the company’s direction for Chrome OS. Chrome OS is Google’s entry into the operating system market, joining names like Apple OS X, Microsoft Windows and many Linux variations – Ubuntu, Suse and Moblin – to name a select few distributions. Google is promoting Google Chrome OS as a cloud service, with most applications running from the internet rather than on the local system. Examples of this include the popular Google services Google Docs, Gmail, Google Reader and others. In doing so, Google has already attracted the ire of some commentators. Michael Gartenberg in a column for Engadget disagreed with the approach, expressing that not all computer users spend 90 percent of their day in a browser doing their work, e-mail and networking.
Yet, it does seem as though the cloud holds enough promise for a broad enough group of users that Chrome OS will gain some traction when it does launch, which is anticipated for next year. Chrome OS would provide users of netbooks a lightweight, free and easy to use operating system, though the question remains – How long will netbooks be viable? As the market encounters more powerful cell phones and greater connectivity, some pundits are placing bets on smart phones being the future, and not netbooks. It is important to point out that Google has already placed a bet on smart phones with the introduction and continued uptake of the Android smart phone operating system.
Google’s efforts with Chrome OS have interesting implications for those developing hardware. The growing variety of operating system choices result in the need for increased testing across a wide array of devices. With entries like Chrome OS and Moblin gaining market traction, firms producing everything from cameras to keyboards now must consider how their customers will interact with devices. For many years, Microsoft Windows and Apple offerings combined for near market saturation – resulting in a manageable test and interoperability scenario for producers of both software and hardware. Now the picture is becoming much less clear for which operating system a consumer might be bringing their new hardware home to.
If you want to review Google Chrome OS yourself, we recommend downloading it from gdgt.com, as their hosting is the fastest way to get Chrome OS.

Recently, Allion announced a USB Battery Charging Test Fixture pre-sale, which runs through the end of this month. This USB testing tool easily measures the performance of mobile phone device chargers. The test fixture looks at power consumption, over shoot (signal or function exceeding steady-state value), under shoot (signal or function lower than steady-state value) and short-recover time. The USB test fixture was developed to adhere to the Battery Charging 1.1 Specification defined by the USB Implementers Forum (USB-IF).USB Battery Charging 1.1One feature that makes USB a compelling interconnect technology is its battery charging ability. As USB devices become more powerful and advance with new features, new battery charging capabilities are needed. This is where the USB Battery Charging 1.1 specification, which was released as a new USB Device Class specification earlier this year, comes into play.
New capabilities enabled by Battery Charging 1.1:
Device detection whether they are attached to a PC or charging port. When attached to a charging port, devices can draw power before they are recognized.
Portable devices with dead batteries are now able to draw current from a PC before they are recognized.
Devices plugged into a docking station can act as host to downstream peripherals, while drawing current from the docking station.
The Accessory Charger Adapter enables a portable device with a single Micro-USB connector to charge at the same time it is attached to another device, such as a headset.
Portable devices can reduce connector costs by offering battery charging, connection to a host and/or connection to a peripheral using a single Micro-USB receptacle.
USB test equipment can effectively enhance testing during all product development stages. Allion strives to deliver the most cost effective and competitive testing fixtures to fulfill the needs of developers. Quality testing ultimately leads to quality products and financial savings for customers.

This week marked the availability of Windows 7 to consumers worldwide. The operating system is being touted as a vast improvement over its predecessor, Windows Vista. One item that Microsoft focused intensely on when developing Windows 7 was user experience – providing a smooth, snappy and bug free experience for its customers.
So what steps are necessary to deliver a positive experience across the millions of possible PC configurations in the marketplace?
Earlier this summer, we detailed the Windows Logo Program. This program, primarily for hardware manufacturers, ensures that systems and devices will function properly with Windows operating systems (Windows Server® 2008 R2, Windows Server 2008, Windows Vista and Windows 7). It also signals to consumers that the product has been tested to verify it meets Microsoft standards for Windows compatibility. This is essential as consumers worldwide load their new Windows 7 discs into millions of PCs from hundreds of manufacturers. What could be a compatibility nightmare appears to be a smooth transition that is bolstering Microsoft’s position in the market. To further ensure that consumers do not run into any roadblocks while making the transition to Windows 7, Microsoft has enhanced the requirements to receive a logo for Windows 7 hardware.

A new requirement mandates that firms seeking a Windows Logo first secure a USB certification. USB certification is a critical certification in the PC industry, and it will minimize the chance of a consumer’s USB device not performing as anticipated with the Windows operating system. The new policy is critical for hardware vendors and system manufacturers, who are preparing to submit their USB devices and systems for Windows Logo Program submission.
Simply stated, any devices (webcams, keyboards, mice) or hosts (desktops, laptops or netbooks) seeking a Windows logo must first receive certification from the USB Implementers Forum. This certification guarantees compliance to the USB standard and in turn, promotes the greatest level of interoperability between USB hosts and devices.
For consumers, this new requirement is an important step. It will ensure that purchased devices carrying the Windows and certified USB logos will work as expected with their PC bearing the logos.

SuperSpeed USB Momentum

2009-10-27T18:30:00.000-07:00

(October 26th, 2009)
During the week of Intel Developer Forum San Francisco (Sep. 22-24), the USB Implementers Forum (USB-IF) announced that the first certified SuperSpeed USB (USB 3.0) commercial product was available. Commercial availability of the host controller from NEC Electronics Corporation advances the technology toward broad adoption among host and peripheral manufacturers.
Allion covered the NEC host controller unveiling last May and the certification of the device by the USB-IF is an indication to PC manufacturers that the component will be interoperable with the entire SuperSpeed USB device ecosystem. The NEC Electronics host controller uses a PCI Express 2.0 bus, allowing designers to add up to two USB 3.0 interfaces to systems containing the PCIe interface.
What USB 3.0 Brings to the TableSuperSpeed USB also brings compelling enhancements to the popular USB standard. SuperSpeed USB delivers data transfer rates up to 10 times faster than Hi-Speed USB (USB 2.0), optimizes power usage and offers backward compatibility with previous generations of USB (see Comparing USB 2.0 and USB 3.0 for more).
USB 3.0 AdoptionSo when will USB 3.0 be in the hands of consumers? Analyst firm In-Stat anticipates that SuperSpeed USB will expand upon the broad market adoption of the current USB standard and will make up about 30 percent of the USB market within five years. However, recent announcements from storage manufacturers Buffalo, Freecom and Active Media Products indicate that SuperSpeed USB consumer products will be on store shelves before the end of 2009.
The timeline for USB 3.0 test specification availability is still being determined, but as the technology reaches broader adoption, it is certain test labs will be enabled to verify SuperSpeed USB designs and products.

SATA thinks small with mSATA

2009-10-14T00:29:00.001-07:00

Serial ATA International Organization (SATA-IO), the consortium behind serial ATA technology, is developing a new specification that will outline a mini-SATA (mSATA) interface controller. The new connector will enable easy SATA integration in small form factor devices. mSATA will offer the same speed and reliability of today’s SATA interface standards; providing system designers and manufacturers high performance and cost-effective storage solutions for small CE products like notebooks and netbooks.

From Production to Primetime: TV Testing Makes Viewing Experience Better

2009-10-14T00:27:00.000-07:00

Connecting a digital TV to the wide variety of devices found in a home theater can present challenges. TV signals input/output (I/O) interfaces, standards, and device variety are complex, and they can lead to poor connectivity among TVs and devices.
TV tests aid television developers by ensuring product interoperability between the TV and top consumer devices. In determining the top consumer devices, factors such as market share, customer satisfaction, sales ranking and device generation are considered. A reputable testing facility will purchase the newest devices and buy devices from specific locales. TV tests ultimately help developers sell their products by delivering quality products, which lead to positive reviews.
Some common tests to ensure that the TV can function as it should include:
Cable Capability Test: verifies that the TV and devices work properly with bundled cables.Digital Living Network Alliance (DLNA) test: checks whether the TV can offer DLNA setup and if the TV can play back all supported DLNA files on the connected devices.Full Connection Test: verifies that every I/O port on the TV works properly.Consumer Electronics Control (CEC) Test: verifies CEC function.Input Switching Testing: alters signal sources (switches analog and digital signal source) and verifies the TV’s input and interface functions.Power Function Test: verifies the TV works correctly after powering on or off the TV and devices.Play Back Test: checks if the TV can properly play back media content of the connected device and from the USB interface and determines if the TV can display all supported resolutions.
Ideally, the TV test environment will simulate the most common scenarios for consumers connecting their devices to their TVs. Third party testing at facilities like Allion Test Labs ensure that TVs will properly function.

Apple Moves Smaller with Mini DisplayPort

2009-10-02T00:45:00.001-07:00

The Mini DisplayPort interface is a smaller version of the traditional DisplayPort plug and connector, and was first publicly announced by Apple in 2008. Apple products featuring the Mini DisplayPort connector include the MacBook family of laptops, the iMac, Mac Mini, Mac Pro and the entire Apple Cinema line of displays. The user-friendly Mini DisplayPort connector links the Mac to an LED display, and offers both video and audio support, significantly reducing the number of cables associated with incorporating an external display and speakers.
Mini-DVI vs. Mini DisplayPortUnlike Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort is capable of displaying the high resolutions commonly associated with 30 inch and larger displays. Large displays are becoming more common as DisplayPort integrators Dell and Apple recently released 30 inch product offerings. Laptops with a Mini DisplayPort can connect a computer with to an external display or projector with a VGA or DVI interface by using an adapter.
In early 2009, VESA announced that it would include Mini DisplayPort in the DisplayPort 1.2 specification.
DisplayPort TestingWorking with an independent test lab for DisplayPort testing will help developers build properly functioning DisplayPort products. DisplayPort test categories include:

Physical Layer Test
Link Layer Test
Electrical Test
HDCP Test

The DisplayPort compliance & logo program ensures that products comply with DisplayPort standard guidelines. The DisplayPort Certified Logo ensures that certified products are of high quality and that they will work together seamlessly.

DisplayPort: An Emerging A/V Interconnect

2009-10-02T00:43:00.000-07:00

DisplayPort, an audio-video interconnect standard, is designed to advance display simplicity and the adoption of protected digital outputs on computers. This allows users to easily view commercial HD content and other protected files.
Because DisplayPort signaling can transmit both DVI and HDMI signals (other digital display standards), DisplayPort is compatible with many popular interconnects and subsequently, the consumer devices that utilize the standards. What this means for consumers is the easy incorporation of DisplayPort sources or devices in their homes and offices.
The DisplayPort interface, developed for computers, monitors and home-theater systems by the Video Electronics Standards Association (VESA), and formally approved in 2006, includes DisplayPort Content Protection (DPCP). This content protection capability uses 128-bit encryption and features full authentication and session key establishment. For consumers this means that even commercially protected content will play back over the DisplayPort interface, ensuring a seamless user experience.
DisplayPort technology appears to be gaining momentum. According to a 2008 report from industry analyst firm In-Stat; DisplayPort is predicted to reach the milestone of more than 600 million products shipped by 2012. The DisplayPort Web site lists more than 165 members of VESA, a veritable who’s who of the consumer electrics and PC industries. Many of these companies have announced their intention to implement or support DisplayPort technology into their products. Some notable industry heavyweights, like Dell, for example, already have numerous displays shipping with DisplayPort technology.
DisplayPort TestingWorking with an independent test lab accredited by VESA to perform DisplayPort testing helps ensure that Display Port products will function properly, which is especially essential with consumer video applications.
While VESA does not require certification of DisplayPort products, it is highly encouraged. The DisplayPort Certified Logo reassures end users that certified products will interoperate properly and provide a quality digital display experience.

Ruggedized Computers and Cell Phones: Testing Product Durability

2009-09-13T20:11:00.000-07:00

In an age of continual computing evolution, users often take for granted the usability and durability of their computers and devices. If a consumer drops a cell phone, they anticipate it will survive the fall. If a laptop is left in a sweltering car all day, it’s expected to continue to function properly. Increasingly electronic devices are utilized in environments not normally conducive to the sustained operation of electronic gadgetry: police duty, on the construction job site, combat environments, at sea and in climatic extremes of hot and cold. The sector of devices designed to deal with these extremes is referred to as ruggedized devices.
From cell phones, to GPS devices and laptops the sector is growing as users demand uncompromised performance from their devices in any condition. The delivery of uncompromised performance cannot be left to chance. There are many device tests used to push products to the limit, testing their sustained usability and durability.
Independent test labs like Allion can test computers and devices during the development stage to ensure they’ll operate appropriately, even in the harshest conditions. You can check out some of the ruggedized testing performed at Allion Test Labs in the Panasonic Toughbook video.
One common test is a temperature test that can simulate extreme climates and determine if devices continue to function in brutally hot, cold or wet environments. A static compression test can also be performed to determine a product’s response to extreme compression – an everyday example might be stepping on a device or accidentally driving over it.
Specific equipment allows labs to test battery life and simulate dropping devices from a variety of heights. Drop tests entail lifting the product to pre-determined heights and then releasing the product to hit the ground. If a product consistently functions properly after such a fall, it can be certified at a specific drop level. Common failures in a drop test range from display screens, hard disk drives, or the failure of a devices housing. All failures provide designers with valuable insights that they can use to further reinforce the device from impact.
Device testing enables consumers and those tasked with purchasing rugged devices a set of common specifications to review and ensure the device they intend to purchase will stand-up to even the worst abuse in the field. As future generations of ruggedized electronic devices appear in the market, durability should improve to meet customer demand for go-anywhere electronics.
