Video Transmission for Quantized Variable Bandwidth Networks

Abstract

Transmission of variable bit-rate sources, such as video, over channels with quantized rates is discussed. An optimal scheme for transmission, based on the Viterbi algorithm, is described. A sliding window sub-optimal algorithm is introduced which significantly reduces algorithmic complexity while maintaining near-optimum performance. Simulation of the performances of the optimal and sub-optimal algorithms, as well as comparisons to a constant bit rate channel is completed.
