Rate-distortion analysis of the multiple description motion compensation video coding scheme

Multiple description motion compensation (MDMC) is a multiple description video coding scheme that has shown good error resilience performance. MDMC enables one to vary coding parameters according to the desired trade-off between coding efficiency and error resilience. To fully utilize this advantage, one needs to establish a set of models, relating the rate, encoder distortion, and the end-to-end distortion after transmission, with the encoder parameters and channel parameters. Using these models, one can find the optimal coding parameters for given channel parameters and rate (or distortion) constraints. In this paper, we formulate and validate the rate and encoder distortion models.
