Towards a theory for video coding using distributed compression principles
Thispaper presents an information-theoreticstudy ofvideo codecs that are based on the principle of source coding with side information at the decoder In contrast to the classical wner-Ziv side-infomation source coding pmblem [I], in this work we address the situation where the source and side-information are connected thmugh a state of nature that is unknown to both the encoder and the decoder We dub this framework as Source Encoding with side-information under Ambiguous State of Nature (SEASON). Our objective is to compare the achievable RateDistoiiion (WO)peformance of conventionalvideo codecs designed undertheMotion-Compensated Predictive Coding (MCPC)framework and video codecs designed under the SEASONframework. Ouranalysis shows that under appropriate motion models and for Gaussian Displaced Frame Diflerence (DFD)statistics, the WOperformance of a classical MCPC-based video codec is matched by that of our pmposed SEASON-basedvideo codec, with the latter being characterized by the...
