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.
