An improved iterative algorithm is first proposed to calculate the rate-distortion performance of causal video coding for any continuous sources. Instead of using continuous reproduction alphabets, it utilizes finite reproduction alphabets and iteratively updates them along with transitional probabilities from the continuous source to reproduction letters, thus overcoming the computation complexity...
This paper studies the design and analysis of multiresolution vector quantization (MRVQ) for broadcast channels. Given a broadcast system with MRVQ, a random index assignment, and a coded broadcast channel, we first obtain a closed-form formula for the weighted end-to-end distortion (EED) of the system. Based on the formula, an iterative algorithm is then proposed for designing optimal MRVQ for the...
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...
