Detection and phase lock of 2:2 and 3:2 pull-down video

摘要: Herein described is a system and method of detecting 2:2 and/or 3:2 pull-down video. In addition, aspects the present invention provide to identify lock onto field phase received or video signal. The for in comprises first circuitry that computes unexpected motion values, second implements an alternating straight through crossover function, third performs processing generates one more control signals, pair counters, selection circuitry. computing luminance approximations pixels associated with output frame, differences, difference each absent pixel frame based on five phases.
