Abstract
PURPOSE: To secure the correction for the sequential property of the carrier chrominance signal by giving the action for the fixed time to detect the phase variation of the reference signal in the regenerated signal and then making the detection output effective.
CONSTITUTION: The FM signal Sf is drawn out through HPF13 for the PAL color video signal sent from tracks A and B via heads 11A and 11B, and then the PAL color video signal is demodulated to luminance signal Sy to be supplied to adder circuit 17. At the same time, carrier chrominance signal Sc is drawn out through LPF21 and then supplied to filter 24 after the frequency conversion into carrier chrominance signal Ss and then supplied to adder circuit 17 after elimination of the crosstalk signal between tracks A and B. The mode setting is given at system control circuit 60 at the special regeneration time with control given to switch circuit 31. And signal Ss is delayed by one horizontal period via the delay circuit to be supplied to circuit 31. As a result, no disturbance is caused to the sequential property for signal Ss supplied to circuit 17.
