摘要： Color television receiving apparatus for receiving and demodulating a composite color television signal including hrozintal synchronizing signals, color burst signals, and luminance and chrominance components. This composite color television signal is of the type which additionally may or may not include a VIR signal which, typically, is broadcasted in a predetermined line interval during the vertical retrace period of the composite color video signal. The apparatus includes the demodulator for demodulating the chrominance component, which has been separated from the composite video signal, into its color signal components. A signal generator generates a signal, such as a gate signal, during the predetermined line interval in which the VIR signal is expected. Control circuitry is energized by this generated signal to respond to selected components produced by the demodulator during the line interval in which the VIR signal is provided for producing signals which are used to control the color signal components demodulated by the demodulator, such as to control the hue and saturation of such demodulated components. Manually operable adjusting circuitry is coupled to the control circuitry for selectively varying the control signals in accordance with an operator's particular preference for hue and/or saturation characteristics of the reproduced color video picture. In one embodiment, switching circuitry is provided to selectively energize the control circuitry either with the aforementioned generated gate signal or, in the event that the transmitted video signal is not provided with a VIR signal, with an alternative periodic gating signal, such as a signal derived from the horizontal sync signal.

摘要： 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. By so presetting the storage circuit, the time required for successful VIR-controlled color correction is minimized when the video signal receiving apparatus is switched from, for example, one broadcast channel which does not include a VIR signal to another broadcast channel which does include a VIR signal.In a preferred embodiment, both hue and color saturation are controlled in response to a VIR signal. The level of a selected color difference signal (R-Y), produced during the chrominance reference portion of the VIR signal, is used to control hue; and the level of a simulated color drive signal (B), also produced during the chrominance reference portion of the VIR signal, is used to control color saturation.
