Causal video coding is a coding paradigm where video source frames are encoded in a frame by frame manner, the encoder for each frame can use all previous frames and all previous encoded frames, and the corresponding decoder can use only all previous encoded frames. In this paper, the design of causal video coding is considered from an information theoretic perspective by modeling each frame as a...
Causal video coding is a coding paradigm where video source frames X1, X2, ..., XN are encoded in a frame by frame manner, the encoder for each frame can use all previous frames and all previous encoded frames, and the corresponding decoder can use only all previous encoded frames. In the special case where the encoder for each frame Xk is further restricted to enlist help only from all previous encoded...
Causal video coding is considered from an information theoretic point of view, where video source frames X1, X2, ? ? ? XN are encoded in a frame by frame manner, the encoder for each frame Xk, k = 1, ? ? ?, N, can use all previous frames and all previous encoded frames while the corresponding decoder can use only all previous encoded frames, and each frame Xk itself is modeled as a source Xk = {Xk...
Consider a source network in which a finite alphabet source X = {X i}iinfin=0 is to be encoded and transmitted, and another finite alphabet source Y = {Yi}iinfin=0 available only to the decoder as the side information correlated with X. Traditionally the channel between the encoder and decoder in the source network is assumed to be one-way. This, together with that the encoder does not have access...
