ABSTRACT:
A color video signal reproducing apparatus comprises a carrier chrominance signal separation circuit for separating a carrier chrominance signal from a color video signal reproduced from a recording medium, a luminance signal separation circuit for separating a luminance signal from the reproduced color video signal, a demodulating circuit for demodulating the separated carrier chrominance signal into two color difference signals, where the demodulating circuit consists of demodulators for demodulating the carrier chrominance signal into the two color difference signals, an oscillator for supplying a predetermined frequency signal to the demodulators, and a control circuit for controlling the oscillation frequency of the oscillator according to a jitter component in the carrier chrominance signal, a reference signal producing circuit for producing a reference signal having a predetermined frequency, a modulating circuit for modulating the reference signal from the reference signal producing circuit, respectively, by the color difference signals from the demodulating circuit, and a color video signal obtaining circuit for obtaining a color video signal by adding an output signal of the modulating circuit and the separated luminance signal.
