ジヨン受像機。 a YC separation circuit that separates the composite video signal into a first luminance signal and a first chrominance signal; an external input terminal that inputs a pair of externally separated second luminance signals and second chrominance signals; the first luminance signal and the second luminance signal;
a first switch means for selecting one of the luminance signals; a second switch means for selecting one of the first color signal and the second color signal; and one of the luminance signals selected by the first switch means. A color television receiver comprising a luminance signal processing circuit for processing one of the luminance signals, and a color signal processing circuit for processing one of the color signals selected by the second switch means,
The luminance signal receives a delay time equivalent to the delay time that the chrominance signal receives in the chrominance signal path from the YC separation circuit to the second switch means in the luminance signal path from the YC separation circuit to the first switch means. A first delay means is provided between the YC separation circuit and the first switch means, and the delay time is equivalent to the delay time that the color signal undergoes in the color signal path after the second switch means. A color television receiver comprising second delay means for receiving a luminance signal in a luminance signal path after said first switching means.
