Soft-decision decoding of linear block codes for robust H.263 video transmission in a zero-mean, additive white Gaussian noise (AWGN) channel is investigated. We implement an effective error concealment (EC) scheme at the source decoder to reduce the annoying artifacts caused by decoding a corrupted bit stream. To alleviate the spatial and temporal error propagation, an error prevention (EP) strategy is introduced at the H.263 encoder. Simulation results show that a large portion of the peak signal-to-noise ratio (PSNR) gain is obtained by ordered statistics decoding of the received sequence. Furthermore, the residual channel coding errors are concealed and compensated by realizing the proposed EC and EP schemes
