ABSTRACT:
A video signal testing method and the system thereof supplying video signals on a video connector into a cyclic redundancy check circuit through a delay circuit, generates a fixed value corresponding to the specified testing full-frame. The generated value is stored in a RAM of unit under test and compared with a previous built-in value to justify the correctness of the video signals without the aid of human naked eyes.
