うにしたことを特徴とするビデオ信号回路。 In a circuit that creates a PAL video signal for a PAL video camera, horizontal burst flag signals of opposite phases are added to the R-Y and B-Y color difference signals to adjust the burst level. The burst flag signal is input to the base of the transistor, and the reverse phase signals of the reflector and emitter are respectively R-
A video signal characterized in that by adding to the Y and BY color difference signals, it is possible to simultaneously perform burst level adjustment of the RY and BY color difference signals by simply adjusting the level on the base side. circuit.
