A perceptual Sensitivity Based Redundant Slices Coding Scheme for Error-Resilient Transmission H.264/AVC Video

In this paper, redundant slices feature of the H.264/AVC codec is evaluated. In order to trade off compression efficiency and error robustness of a H.264/AVC codec with redundant slice capability, we propose a novel perceptual sensitivity based redundant slices coding scheme. The perceptually sensitive regions are determined by using a simple yet effective perceptual sensitivity analysis technique, which analyzes both the motion and the texture structures in the original video sequence. The experimental results show that our proposed algorithm can remarkably improve the reconstructed video quality in the packet lossy network
