Abstract
Digital color signal processing circuitry includes a multiplier which multiplies two demodulated digital color-difference signals by a digital color-saturation signal to provide three time-division-multiplexed signal pairs, each of which is added to the digital luminance signal by an adder. The color-saturation-signal input of the multiplier is preceded by a second multiplier to which the color-saturation signal and multiplier factors stored in a memory (sp) are applied. These multiplier factors are permanently stored by the manufacture of the color-television receiver or can be varied or adjusted during the operation of the receiver. The three adders are followed by three digital-to-analog converters which provide the analog color signals.
