RT-AV400

TV Set Black Box Testing Using a Chamber

rt-av400

RT-AV400 is integrated framework for fully automated TV testing using optical inspection of TV screen.

RT-AV400 is camera based solution. Functional verification of Device Under Test is based on captured image analysis

RT-AV400 is constructed as a black chamber in order to have invariant light conditions.

RT-AV400 is easily configured and customized for a wide range of electronic devices: TVs, mobile phones, game consoles, tablets.
