An Error Resilient Technique Using Reversible Data Embedding in H.264/AVC

An Error Resilient technique using reversible data embedding in H.264/AVC aiming at high quality recovery under high loss rate is proposed. For compressed videos, predictive coding techniques increase the dependency between frames. When error occurs, it may propagate to other frames. In H.264/AVC, in order to achieve higher compression ratio, it adopted intra prediction to further compress intra frames. Such technique also results in error propagation in intra frames. This paper proposes a new error resilient technique using reversible data embedding in H.264/AVC. The use of reversible data embedding technique is to provide better restoration. Simulation results demonstrate the proposed scheme outperforms current existing techniques on robustness and recovery quality.
