초록정보

Digital coding of the NTSC color TV signal is classified into two types; One is component coding, the other is composite coding. In component coding, a composite color TV signal is separated into luminance and two chrominance components, which are then encoded individually. In composite coding, the color composite signal is encoded directly. Looking well into the future, one would envisage an all_digital system, then it is generally accepted that the component coding is most desirable. A component coding involves the digital demodulation of the composite color signal, the implementation of the compression algorithms on the subsampled component signals, and digital reconstruction of the processed color composite signal. At first, different combinations of comb filters, band pass filters, hilbert filters and interpolators are used to investigate their effects on composite_component separation and reconstruction. And then, we study on the coding algorithms of the separated component signals. We take an idea from the characteristics of component signals in color video image, so that this thesis presents an adaptive DPCM coding system which provides good performance in chrominance signals.
