TLDR
This work reports the first results on a Wyner-Ziv coding scheme for motion video that uses intraframe encoding, but interframe decoding, and suggests that an asymmetric video codec could achieve similar efficiency.Abstract:
In current interframe video compression systems, the encoder performs predictive coding to exploit the similarities of successive frames. The Wyner-Ziv theorem on source coding with side information available only at the decoder suggests that an asymmetric video codec, where individual frames are encoded separately, but decoded conditionally (given temporally adjacent frames) could achieve similar efficiency. We report the first results on a Wyner-Ziv coding scheme for motion video that uses intraframe encoding, but interframe decoding.read more

Distributed Video Coding
TL;DR: The recent development of practical distributed video coding schemes is reviewed, finding that the rate-distortion performance is superior to conventional intraframe coding, but there is still a gap relative to conventional motion-compensated interframe coding.

PRISM: A Video Coding Paradigm With Motion Estimation at the Decoder
TL;DR: Encouraging preliminary results on real-world video sequences are presented, particularly in the realm of transmission losses, where PRISM exhibits the characteristic of rapid recovery, in contrast to contemporary codecs, which renders PRISM as an attractive candidate for wireless video applications.

Distributed source coding using syndromes (DISCUS): design and construction
TL;DR: This work addresses the problem of compressing correlated distributed sources, i.e., correlated sources which are not co-located or which cannot cooperate to directly exploit their correlation and provides a constructive practical framework based on algebraic trellis codes dubbed as DIstributed Source Coding Using Syndromes (DISCUS), that can be applicable in a variety of settings.

Compression of binary sources with side information at the decoder using LDPC codes
TL;DR: Low-density parity-check (LDPC) codes can be used to compress close to the Slepian-Wolf limit for correlated binary sources with side information at the decoder based on viewing the correlation as a channel and applying the syndrome concept.
