ABSTRACT:
A system for transmitting carrier chrominance signals of color video signals has a maximum transmissible optimum level. A detection circuit responds to the level of the carrier chrominance signal comprising a carrier chrominance signal component and a color burst signal of a color video signal to generate a level control signal. A level control circuit responds to the level control signal, so that the peak value of the carrier chrominance signal becomes a value which is always substantially equal to the transmissible optimum level of the signal transmission system, and sends out the level controlled carrier chrominance signal to the signal transmission system.
