COMPRESSION/DECOMPRESSION PRODUCTS

With the advance in the performance of computer chips, it is now possible to compress information into a much smaller space by using complex compression algorithms. These algorithms, which once would have required a high-powered computer the size of a tennis court, can now run on a single low cost computer chip which carries out the compression/decompression process. This means that tremendous amounts of additional capacity can be extracted from the existing and new telecoms infrastructure (including the copper wires which connect all our telephones) This capacity can be used to carry new information such as video, which requires an enormous amount of capacity to convey information such as movement and color. There are several compression technologies, luckily, however, the interactive-TV competitors have all thrown their weight behind the same method of compressing the feed-forward video signal from the broadcaster to the receiver: MPEG. The semiconductor industry has quickly begun building standard encoders/decoders to the Moving Picture Experts Group (MPEG) standard, ensuring full Interoperability . So entrenched is MPEG that even superior alternatives have become largely moot, and it appears that MPEG will likely stamp out the various methods used in proprietary systems.MPEG-2 is alos an international standard. Embraced worldwide by television equipment makers, consumer electronics companies, telephone companies, cable system operators and direct broadcast satellite system operators, MPEG-2 is replacing the NTSC and PAL analog formats for storing and transmitting video.

LSI Logic¹s L64002 is a single-chip MPEG2 source decoder that combines a video decoder that is compliant to the MPEG standard Main Profile at Main Level with a two-channel MPEG audio decoder. The L64002, however is more than just a single chip MPEG2 audio/video source decoder. The architectural elements of the device were developed to enable a unique feature set that provides a complete, cost-effective solution for compressed digital interactive television applications. These architectural elements include a customized RISC engine and a video display and graphics controller. In addition, the L64002 provides mechanisms that allow for audio/video synchronization without the use of an external VCXO.
