Abstract: In a color television system having a video tape recorder and a color television receiver which includes an automatic control circuit for automatically controlling color level and hue with a reference signal contained in a predetermined horizontal scanning line section of a video signal, and which is so designed that a broadcasting signal and a reproduced signal of the video tape recorder are selectively received by the color television receiver, the automatic control circuit rendered inoperative in response to a change-over operation by which the color television system is changed over to apply the reproduced signal of the video tape recorder to the color television receiver.

Abstract: Hue and color saturation are controlled in response to a received VIR signal, the latter having a chrominance reference portion and a luminance reference portion. The level of a preselected one or more demodulated color signals which are produced by the color demodulator in color video signal receiving apparatus is detected during the time that the VIR signal is received. The level-detected demodulated color signal is used to produce a control signal for controlling the hue or color saturation. A storage circuit, such as a capacitor, is provided to store the control signal throughout the duration which separates successive VIR signals. A VIR detector is provided for detecting the presence of a VIR signal in the received video signal; and when the absence of a VIR signal from the received video signal is detected, the control signal storage circuit is preset to a predetermined value.
