ABSTRACT:
A video signal processing apparatus used for a video tape recorder performs chrominance signal processing which is digitalized. The chrominance signal is up-converted and phase-shifted in a recording block, and, in a reproducing block, phase-shifted in the opposite direction, filtered by a comb filter, compensated for jitter, and up-converted to the original chrominance signal. Both the recording block and the reproducing block are digitalized or only the reproducing block is digitalized. The digital chrominance signal processing circuit includes an A/D converter, a digital phase shifter, a digital comb filter, a digital jitter compensator, and a D/A converter.
