PURPOSE:To achieve the suppression of the crosstalk of a color signal and line correlation at a time by a video signal by using a broad-band delay line and by transmitting a video signal, containing a luminance signal and a color signal, through the delay line. CONSTITUTION:To the output terminal of a switch 21, a video signal from one- horizontal-scanning-period video delay line 22 in the last horizontal scanning period is connected and in a mixture 24, a luminance signal in the last horizontal scanning period is entered. A mixture 25, on the other hand mixes only a video signal generated in the last horizontal scanning period, so the video signal in the last horizontal scan ning period is obtained as the output of the mixer 25 and supplied to an HPF26 for band limitation, so that a color signal generated in the last horizontal scanning period is supplied to the mixer 24. Thus, a mixed video signal in the last horizontal scanning period added the luminance signal and color signal in the last horizontal scanning period appears at the output of the mixer 24, thereby compensating a dropout. |
