Recording and reproducing system for color video signals. |
摘要 |
<p>A color video signal recording system comprises means (5, 6) for producing a quadrature two-phase balance-modulated color signal by subjecting a subcarrier to quadrature two-phase balanced modulation by two color signals, means (10) 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 said quadrature two-phase balance-modulated color signal, means for multiplexing said quadrature two-phase balance-modulated color signal and said demodulation-purpose reference phase signal together with a carrier luminance signal, and means (14) for recording said multiplex signal.</p><p>The system minimizes deviation of hues from the original as well as that of color saturation from the original and eliminates drop-out or missing of color information, thereby ensuring a high quality of reproduced pictures.</p> |
