ABSTRACT:
The video signal processing apparatus of the invention is an apparatus for processing a video signal superimposed on a carrier signal by digitizing. The video signal is sampled at a sampling frequency equal to 2n (where n is 2 or higher integer) times the frequency of the carrier signal to form 2n sample data per period of the carrier signal. After the formed sample data have been memorized in the sampling sequence, the corresponding 2n sample data to one period of the carrier signal are read in a different sequence from that when the aforesaid memorizing was carried out. Thus, the video signal can be processed by using means of simple structure.
