Abstract
A digital chroma signal processing apparatus wherein control signals represent the burst period, the image period and the remaining period of a digital chrominance signal. A multiplier receives a selected one of an ACC signal and the chrominance signal, multiplies it with a second signal and outputs the resultant produced. A matrix coefficient section includes a generator to generate a plurality of matrix coefficients; a cyclic arrangement of dynamic shift registers to store selected matrix coefficients; and a multiplexer to input to the dynamic shift registers, in accordance with the control signal, a selected one of the product signal and the output signal of the dynamic shift registers. The second signal is generated by a selection between the ACC signal and the output signal of the shift registers. The resultant chrominance signal processing circuit is thus controlled by a small number of simple control signals.
