Numerous voice, still image, audio, and video compression standards
have been developed over the last 25 years, and significant
advances in the state of the art have been achieved. However, in
the more than 50 years since Shannon's seminal 1959 paper, no rate
distortion bounds for voice and video have been forthcoming. This
volume presents the first Rate Distortion Bounds for Voice and
Video that actually lower bound the operational rate distortion
performance of the best-performing voice and video codecs. Recently
there has been much concern expressed about the gap between lossy
compression theory and practice. Rate Distortion Bounds for Voice
and Video specifies, for the first time, this gap for voice and
video, and points the way forward to improving the performance of
practical voice and video codecs. Recent results on obtaining rate
distortion functions for both voice and video sources are
presented, which overcome past limitations on source modeling by
employing composite source models to achieve more accurate modeling
of the different voice and video source modes. This is essential
reading for researchers in Information Theory and Signal Processing
working on theoretical and practical aspects of data compression.
