Abstract
PURPOSE: To enable to record the luminance signal and chroma signal in common band, to enable narrow required band, and to reproduce the luminance signal in excellent S/N ratio, by controlling the coded chroma signal identified according to the envelope of reproduced superimposing signal, cancelling the coded chroma signal of the superimposing signal with the controlled signal, and reproducing the luminance signal with the FM demodulation.
CONSTITUTION: IN the recording system, the color video signal is separated 2, 4 into the luminance and chroma signal, and the luminance signal performed by FM3 is superimpsed 8 on the chroma signal coded modulation 6 and is recorded. In reproduction system, the coded chroma signal is identified 17 with the superimposing signal is reproduced and the coded chroma signal identified 17 according to the envelope of the reproduced superimposing signal is controlled 19, the coded chroma signal component of the superimposing signal is cancelled 20 with the coded chroma signal controlled 19, and the luminance signal is reproduced with the FM demodulation 21. Further, since the luminance signal and chroma signal can be recorded in common band, required band is narrow and the luminance signal excellent in S/N can be reproduced.
