ABSTRACT:
An analog composite color video signal is recorded on and reproduced from a recording medium by frequency modulation and demodulation. A circuit is provided for digitally separating the video signal to a first frequency band signal and a second frequency band signal including a color subcarrier. Another circuit converts the frequency band signal to first and second base band signals, a circuit for time-compressing at least the first and second base band signals, a circuit for recording and reproducing the first frequency band signal and the time-compressed first and second base band signals in an analog mode, a circuit for digitally recombining the reproduced first frequency band signal and the time-compressed first and second base band signals, and a circuit for converting the recombined digital video signal to the analog composite color video signal.
