Error-Resilient and Error Concealment 3-D SPIHT Video Coding with Added Redundancy*

摘要

In this paper, we propose a multiple description (MD) video coding algorithm based on error-resilient and error concealment set partitioning in hierarchical trees (ERC-SPIHT). Compared to ERC-SPIHT, the novelty of the proposed approach is the injection of additional redundancy into the substreams so that the coefficients in the spatial root subband are protected highly from transmission errors. Experimental results on different video sequences show that the proposed method maintains error-resilience with high coding efficiency. In particular, our results demonstrate that the proposed algorithm achieves a significant improvement on video quality by up to 2.24 dB in the presence of a substream loss compared to ERC-SPIHT.
