Cooperative Processing for Improved NTSC Chrominance/Luminance Separation
NTSC cross-color/cross-luminance artifacts are introduced in the television camera during NTSC encoding and also result from imperfect chrominance/luminance separation at the receiver. Camera-induced artifacts produce spectrally contaminated regions that cannot be properly separated into their original component form. The cooperative processing system described uses source processing to prevent camera-induced artifacts, and receiver processing to optimally separate the uncontaminated NTSC signal. Various source and receiver processing schemes, using line, frame, and field-comb filters, are described. Finally, computer simulation results of the various systems are discussed.
