Abstract

PURPOSE:To improve color deviation in an image by passing a video signal in which a high frequency signal is demodulated when it is selected through a band-pass delay circuit to correct the delay characteristic of the signal. CONSTITUTION:A high frequency television signal is inputted from a terminal 1A, and is detected at a video demodulation circuit 11, and is supplied to the terminal X side of a signal switching circuit 12. Meanwhile, an external video signal supplied from the outside is supplied from a terminal 1B to the terminal Y side of the signal switching circuit 12. The video signal on one side selected at the signal switching circuit 12 is separated to two groups, and one is supplied to the Y side terminal of a second signal switching circuit 14, and the other, after passing the band-pass delay circuit 13, is supplied to the X side terminal of the second signal switching circuit 14. And since phase distortion is supplied to the video signal at a broadcast station side, it is processed at the delay correction circuit 13, then, a total delay characteristic can be flattened. In such a way, it is hard to generate the deterioration in picture quality such as the color slippage, etc.
