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 sub-streams so that the coefficients in the spatial root sub-band 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 sub-stream loss compared to ERC-SPIHT.
