Abstract:
A video signal processor for supplying an analog signal, comprising:a decoder supplied with an NTSC signal and producing a digital video signal with a vertical synchronous frequency and a horizontal synchronous frequency satisfying a standard,an encoder connected to said decoder and producing said analog video signal with a color sub-carrier frequency satisfying a standard, anda signal generator connected to said decoder and said encoder and supplying a first output signal, used in generation of at least a horizontal synchronous frequency (f.sub.H), and a second output signal, used in the generation of a color sub-carrier frequency (fsc), to said decoder and said encoder respectively, said first output signal and said second output signal being regulated such that the relationship between f.sub.H and fsc isfsc={(1135/4)+(1/521)}.times.f.sub.H
