VIDEO SIGNAL PROCESSING DEVICE AND METHOD, RECORDING MEDIUM, AND PROGRAM

摘要

A video signal processing device and method, a recording medium, and a program which can preferably be used for judging whether an input video signal is a standard signal or a non-standard signal. A free-running vertical synchronization edge counter (31) increments the count value circulating from 0 to 7 in synchronization with the preceding vertical synchronization signal xAVD and outputs the count value to a free-running field ID edge counter (32) and a comparison circuit (33). The free-running field ID edge counter (32) increments the count value in synchronization with the rise edge and the fall edge of a field ID signal AFD. The comparison circuit (33) generates a non-standard signal detection signal in response to the FD edge count value at the timing when the V count value is 7 and the vertical synchronous signal xVD shows the L level. The present invention, for example, can be applied to a TV receiver.
