From Production to Primetime: TV Testing Makes Viewing Experience Better

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.
