Abstract

PURPOSE: To enable to obtain good reproduced carrier chrominance signal, by providing the burst signal phase detection means of reproduced carrier chrominance signal, in the reproduction of PAL system color video signal.
CONSTITUTION: The PAL color video signal is reproduced with the video heads 10a and 10b, and FM luminance signal and the reproduced low band conversion carrier chrominance signal are respectively obtained. After the AM component is rejected from FM luminance signal with the limiter circuit 14, it is reproduced luminance signal with FM demodulasion 15. On the other hand, the reproduced low band conversion carrier chrominance sighal is frequency-converted 19 with the signal from the APC(automatic phase control) circuit 25, and the cross talk component is rejected with the comb type filter 23 and it is the reproduced carrier chrominance signal. The APC circuit 25 picks up the burst signal and after the phase comparison 28 and phase detection 30, it is connected to the phase discontinuity detector of 180 or 90°, and phase change is made.
