ABSTRACT:
A video signal processing system which detects a change of the video data in the video signal supplied by a source by comparing the source video signal with a variable reference signal derived from a predetermined number of sampled fields of the source video signal but which excludes the video data of those pixels whose video data fluctuates during the sampled frames.
