Rate-distortionoptimized mode selection and synchronization marker insertion algorithmsare introduced. The resulting video communication system takes intoaccount the channel condition and the error concealment method used bythe decoder, to optimize video coding mode selection and placement ofsynchronization markers in the compressed bit stream. The effects ofmismatch between the parameters used by the encoder and the parametersassociated with the actual channel condition and the decoder errorconcealment method are evaluated. Results for the binary symmetricchannel and wideband code division multiple access mobile network modelsare presented in order to illustrate the advantages of the proposedmethod 收起
