Abstract
The present invention is related to a video signal processing apparatus and method, a recording medium, and a program which are suitably for use in determining whether an input video signal is standard or nonstandard. In synchronization with the edge of an advance vertical sync signal xAVD, a free-running vertical sync edge counterincrements by 1 the count value which cycles between 0 through 7 and outputs the count value to a free-running field ID edge counterand a comparator. In synchronization with the rising and falling edges of a field ID signal AFD, the free-running field ID edge counterincrements the count value by 1. The comparatorgenerates a nonstandard signal detection signal in correspondence with the FD edge count value with the V count value being 7 and a vertical sync signal xVD being at L level. The present invention is applicable to TV receivers for example.
