We have developed a low-power MPEG-2 codec LSI which has MPEG-2 encoding and decoding functions, high resolution still picture functions and a progressive frame encoding function. This LSI is specifically designed for realizing compact and low cost consumer cameras.

This compact, single chip MPEG-2 audio/video decoder performs all necessary signal processing required for digital satellite TV and cable television (CATV) receivers based on the main profile at main level (MPEG-2 MP@ML) standard. This decoder uses 135,000 gates (2-input NAND equivalents) and occupies 8.6/spl times/9.3 mm/sup 2/ in a triple-layer-metal, 0.5 /spl mu/m CMOS standard-cell process and is much smaller than any MPEG-1/MPEG-2 decoder previously reported.

A description is given of a still video transceiver that transmits full-colour still pictures to anywhere in the world over the general world-wide telephone networks. The system uses highly efficient picture coding that compresses picture data to about 3 bit/pixel with little degradation of quality. This accomplished by the combination of discrete cosine transform (DCT) and entropy coding. Highly reliable transmission under bad telephone-line conditions is realized by the combination of retransmission and fallback techniques. Experimental results of the data compression and transmission of a standard picture by the still video transceiver system are shown. >
