Spatial subsampling-based multiple description video coding with adaptive temporal-spatial error concealment

The encoded bitstream of a typical video compression method is vulnerable to errors during transmission over lossy network. Multiple Description Coding (MDC) is an error resilient video coding suitable for real-time applications when retransmission is unacceptable. Subsampling-based MDC with error concealment is often effective for mitigating unpredictable losses. In this paper, a spatial subsampling based MDC with an adaptive concealment method is described. Error concealment is done using the motion information from its spatial-temporal neighbors. Preliminary experimental results exhibit the efficacy of the proposed method.
