ABSTRACT:
A method of and apparatus for regulating color in a color broadcasting receiver is disclosed and is composed of a tuner, a demodulator, and a burst level detector for detecting the color burst level of a video signal output from the demodulator and outputting the color burst level as a corresponding control voltage signal. A color controller is disclosed for controlling the color by emphasizing or attenuating the high band components of the video signal output from the demodulator in accordance with the control voltage level from the burst level detector, so that it is possible to receive video signals without much change in color regardless of the variation of the voltage standing wave ratio (VSWR) that varies according to changes in the connection between the broadcast antenna and RF cable.
