Abstract
A color separator (12) for a digital television receiver (10). The incoming television signal is directed to two different paths in the color separator (12). Along a first path, the luminance component is separated by an analog Y separator (12a) and then sampled by an A/D converter (12b) at a rate that will provide a desired number of samples per display line. Along a second path, the composite signal is sampled by an A/D converter (12c) at a rate appropriate for digital color separation, and then the chrominance samples are separated using a digital C separator (12d). A scaling unit (12e) then scales the chrominance samples to provide a desired number of samples per line.
