ABSTRACT:
A color video signal recording system comprises means for producing a quadrature two-phase balanced-modulated color signal by subjecting a subcarrier to quadrature two-phase balanced modulation by two color signals, means for producing a demodulation-purpose reference phase signal which has the same frequency as that of the subcarrier and which is to be frequency-interleaved with the quadrature two-phase balanced-modulated color signal, means for multiplexing the quadrature two-phase balanced-modulated color signal and the demodulation-purpose reference phase signal together with a luminance signal, and means for recording the multiplex signal on a recording medium after subjecting it to angle modulation. In a reproducing system, the reproduced signal is subjected to angle demodulation after being limited in its amplitude, and the luminance signal, the quadrature two-phase balanced-modulated color signal and the reference phase signal are separated from the demodulated signal, the quadrature two-phase balanced-modulated signal being then demodulated on the basis of the separated reference phase signal.
