Abstract
With the emergence of high speed packet networks as proposed in CCITT Study Group XVIII, metropolitan area networks as defined in IEEE 802.6, and multimedia, high capacity storage such as CDROMs, there is renewed interest among image processing specialists in achieving high bit rate compressions without severe compromises in image quality. Advances in signal processing techniques and their implementation in VLSI have lead to the point where it is now possible to digitally encode full motion video sequences at less than 1.5 Mbps with a spatial and temporal resolution comparable to that commonly viewed on a standard VHS video tape recorder. Work at the David Sarnoff Labs on DVI encoding for CD-ROMs has demonstrated impressive image quality for scenes compressed to an average of l.SMbps. Lippman and his colleagues at MIT Media Lab, also are making significant progress in improving the image quality while maintaining the same 1.5 Mbps rate (important because it is the transfer rate of CD-ROMs). Recently, work at Bellcore analyzed a broad spectrum of video material and determined the feasibility of achieving 1.5Mbps while maintaining near VCR quality.
