Abstract
Cross color from composite television signals is suppressed by averaging baseband chrominance samples spaced a certain number of frames apart, or when motion is detected in the television signals, by averaging baseband chrominance samples spaced a certain number of lines apart. Cross color suppression when motion is detected may be improved by low-pass filtering the line-spaced chrominance sample average. Both NTSC and PAL implementations are presented.
