In this paper, we propose a generic error resilient video coding (ERVC) scheme using embedded Wyner-Ziv (WZ) description. At the encoder side, a joint source-channel R-D optimized mode selection (JSC-RDO-MS) algorithm with WZ-coded anchor frames is statistically studied and developed. Given a stationary first-order Markov Gaussian source, the proposed mode optimization is justified by an analysis...
This paper proposes an Iterative Joint Source-Channel Decoding (IJSCD) scheme for error resilient transmission of H.264 compressed video over noisy channels. Here both the redundancy systematically added by the channel coding and the source semantic residual redundancy in the compressed video sequence are exploited, in a co-operative manner, to detect and correct transmission errors. Specifically,...
In this paper we evaluate the performance of data-partitioned H.264 video transmission using Unequal Error Protection (UEP) Recursive Systematic Convolutional Codes (RSC). Sphere Packing modulation aided Differential Space Time Spreading is used to improve the overall BER performance and to enhance the objective quality of the transmitted video sequence expressed in terms of Peak Signal-to-Noise Ratio...
