ABSTRACT OF THE DISCLOSURE: In a color television receiver adapted to receive a color television signal containing vertical interval reference (VIR) signals, a VIR correction circuit is provided to auto- matically control the hue and color saturation of the received broadcast signal, which signal may also be the video signal from a video tape recorder of the type in which adjacent field signals are recorded with their respective record tracks being skewed relative to each other to permit elimination of otherwise required guardbands between adjacent field tracks. The recorded video signal is reproduced by mixing adjacent horizontal line signals to reduce crosstalk level. A disabling circuit is provided to connect the input terminal of the VIR correction circuit to ground when the receiver is switched to the output of the video tape recorder in playback mode to prevent false VIR signals due to the mixing from affecting the reproduced colors.
