Abstract
A method estimates bit rates for sets of coding parameters, based on characteristics of a channel, and an end-to-end distortion is estimated based on signal statistics of the video. A particular set of coding parameters that satisfies an available bit rate of the channel and that minimizes the end-to-end distortion of the video is selected. Motion compensated multiple descriptions of the video are encoded according to the selected set of coding parameters.
