Optimal mode selection and synchronization for robust video communicationsover error-prone networks

In this paper, we describe an effective method for increasing error resilie nce of video transmission over bit error prone networks, Rate-distortion op timized mode selection and synchronization marker insertion algorithms are introduced. The resulting video communication system takes into account the channel condition and the error concealment method used by the decoder, to optimize video coding mode selection and placement of synchronization mark ers in the compressed bit stream, The effects of mismatch between the param eters used by the encoder and the parameters associated with the actual cha nnel condition and the decoder error concealment method are evaluated, Resu lts for the binary symmetric channel and wideband code division multiple ac cess mobile network models are presented in order to illustrate the advanta ges of the proposed method.
