Abstract :
An investigation of coding the NTSC color TV signal in the component form is carried out. C-matrix transform (CMT) and the hybrid (CMT/DPCM) coding are simulated on an intrafield basis. The techniques are found to be closely comparable to the discrete cosine transform (DCT) and the corresponding hybrid coding techniques. CMT, which is an integer approximation to the DCT, is expected to yield almost the same processed picture quality as the DCT with less hardware.
