The circuit has a multiplier (300) receiving a frist signal including a digital chroma signal and multiplying it with a second signal to produce a third signal. A circuit transmits the first signal to the multiplier. A matrix coefficient circuit (200) responds to the third signal to generate a number of matrix coefficients. It has a first selector for selecting the matrix coefficients in time division manner and for producing the second signal. An ACC circuit (301) between the multiplier and the matrix coefficient circuitry produces an ACC signal on application of the third signal.
