“…• Source Coding Efficiency We assume that all substreams are thus received correctly at the decoder. Table 1 shows the average PSNR values for the proposed algorithm, the previous work in [8] and ERC-SPIHT when the total number of substreams is S = 4 or S = 16. When S = 4, the PSNRs obtained with the proposed algorithm and the previous work [8] are lower than ERC-SPIHT (0.15 − 0.19 dB).…”

“…Compared to the proposed video coder, a smaller amount of additional redundancy is inserted among substreams in the previous work [8] since each element in 3D R is only half the magnitude of the one in (2).…”

“…The framework is an improvement of our earlier related scheme [8]. Although the work in [8] allows an important quality improvement, it is restricted to a specific scenario (i.e., only four substreams are created and only one of the substreams allowed lost due to noisy channels). In this paper, we generalize the scheme for the generation of an arbitrary number S of substreams and extend the recovery of missing coefficients.…”

Abstract. 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.
