Abstract

PURPOSE:To ensure stable recording and reproduction in order to obtain a picture on the screen as satisfactory as the conventional color TV picture receiver, by providing VIR eliminating circuit to ensure automatic OFF for VIR control circuit of the color TV picture receiver. CONSTITUTION:VIR eliminating circuit 23 is provided to produce such pulse (b) from gate pulse generating circuit 25 that only the burst signal may remain during the 19-scanning period of signal (a) which is formed by adding (15) the reproduced luminance signal and the reproduced carrier chroma signal together. And during that pulse period, VIR signals (luminance signal and chroma reference signal) are eliminated. Thus, the important problem (large fluctuation of amplitude and phase) caused at VTR can be eliminated although the amplitude and phase fluctuations are not removed, so almost normal screen (as satisfactory as the conventional color TV picture receiver) can be secured.
