This paper addresses the problem of robust communication of predictively encodedvideo in a joint soruce-channel setting.Specifically, the problem of predictive mismatch,where there is a drift between the state of the encoder and the decoder is addressed as avariant of the Wyner-Ziv problem.We propose a video encoding algorithm based on theH.26L video codec which prevents the propagation of error in predictively encoded videoin the event of predictive mismatch (or drift) between the encoder and the decoder.One ofthe main advantages of the proposed approach is that there is minmal loss in performanceover the standard H.26L encoder during error-free transmission, while simultaneouslyallowing error recovery in the event of errors.Using turbo codes as coset codes, we evaluatethe performance of the proposed codec and demonstrate the efficacy of the proposedframework.The performance of the proposed approach can only improve with the use of superior coset codes.
