Abstract
This paper addresses the problem of low-latency robust video delivery over packet networks characterized by a bursty loss process. We propose a joint source-channel coding based video codec which uses distributed source coding (DSC) principles. This codec can efficiently tune to both the source content as well as to the network loss characteristics while respecting stringent latency constraints. Simulation results show that the proposed system is both objectively (in PSNR) and subjectively (visual quality) superior to predictive video coding systems where the encoded bitstream is protected with forward error correction (FEC) codes
