Description
This reference/text discusses a novel compressed-domain approach for designing and implementing digital video coding systems-drastically different from the traditional hybrid approach-and demonstrates how the combination of discrete cosine transform (DCT) coders and motion compensated (MC) units reduces power consumption and hardware complexity, covering fundamental concepts, algorithms, contemporary standards, and applications in SONET optical transcoders. Describes various MC-DCT video coding standards for H.261, H.263, MPEG-1, MPEG-2, MPEG-4, and HDTV Presenting an original approach for complete transform-domain video coding architecture, Design of Digital Video Coding Systems identifies bottlenecks inherent in conventional hybrid block-based motion compensated encoder structures used for all video coding standards develops new compressed-domain coder architecture to circumvent bottlenecks gives integer-pel and sub-pixel DCT-based motion estimation/compensation algorithms for compressed-domain video coder structures estimates displacements of half- and quarter-pel accuracy without image interpolation supplies time-recursive lattice structures to generate DCT coefficients fast and efficiently includes look-ahead, multirate, pipelining, and folding techniques in the design of video coders provides a joint source-channel multistream video coding scheme to combat transmission errors for access networks devises rules that allow pairing conventional hybrid and compressed domain video codecs and more Design of Digital Video Coding Systems is a top-shelf reference for electrical and electronics, signal, image, video processing, computer circuit and systems, digital design, and communication engineers, and an exceptional text for upper-level undergraduate and graduate students in these disciplines.
