ABSTRACT:
A color video signal recording system in which a quadrature two-phase balance-modulated color signal is produced by subjecting a subcarrier to quadrature two-phase balanced modulation by two color signals; and a demodulation-purpose reference phase signal is produced which has the same frequency as that of the subcarrier and which is to be frequency-interleaved with the quadrature two-phase balance-modulated color signal. The quadrature two-phase balance-modulated color signal and the demodulation-purpose reference phase signal together with a carrier luminance signal are multi-plexed and the multiplex signal recorded.
