回路。 a sync separation circuit that separates a sync signal from a reproduced luminance signal; an ACC circuit that uses the sync signal to control a level of a reproduced color signal to a constant level;
It consists of a color killer circuit that automatically operates when there is no color burst signal in the C circuit output and blocks passage of the ACC circuit output, and a detection circuit that detects the presence or absence of the sync signal in the sync separation circuit output. . A video mute circuit, wherein when the detection circuit detects that the synchronization signal is absent, the output of the detection circuit activates the color killer circuit to cut off the reproduced color signal.
