ABSTRACT:
A color video signal recording and reproducing system comprises a circuit for recording and reproducing a recording signal onto and from a recording medium, a modulator for frequency modulating a carrier by a luminance signal separated from an input video signal, a first converter for frequency converting a carrier chrominance signal separated from the video signal into a band which is lower than a band occupied by the frequency modulated luminance signal, a gating circuit for passing the frequency converted carrier chrominance signal with an interval of one track scanning period in which one track on the recording medium is scanned, a first mixer for mixing the frequency modulated luminance signal and the intermittent frequency converted carrier chrominance signal from the gating circuit, where the first mixer alternately produces a mixed multiplexed signal in which the frequency modulated luminance signal and the frequency converted carrier chrominance signal are multiplexed, and a signal solely comprising the frequency modulated luminance signal, for every one track scanning period, and the output signal of the first mixer is the recording signal, a demodulator for demodulating the frequency modulated luminance signal which is separated from a reproduced signal, a processing circuit for processing the intermittent frequency converted carrier chrominance signal which is separated from the reproduced signal, into a continuous carrier chrominance signal in its original band, and a second mixer for mixing the outputs of the demodulator and the processing circuit, to obtain a reproduced color video signal.
