  • System and method for automated testing of digital television receivers
    Patent number: 6741277
    Abstract: There is disclosed a system and method for the automated testing of digital television receivers. The automated test system comprises a digital video signal unit capable of sending a digital video test pattern to a digital television receiver. The digital video signal unit is capable of receiving from the digital television receiver a reconstructed digital video signal representing the digital video test pattern as displayed by the digital receiver television receiver. The automated test system comprises a test processing unit that is capable of comparing the digital video test pattern with the reconstructed digital video signal to determine the video quality of operation of the digital television receiver. The system and method of the present invention compares the digital video test pattern and the reconstructed digital video signal by 1) comparing the amount of jitter, and 2) comparing the signal to noise ratio, and 3) computing percentage similarity between an image block of each of the two video signals.
