Fast error recovery algorithm for Internet video using feedback channel and multi-reference frame

Hybrid compressed video is very vulnerable for packet loss when transmitted over Internet. Feedback channel is very useful to combat error propagation. Multi-reference frame is another useful tool to enhance both coding efficiency and robustness. In this paper, we propose an algorithm which combines feedback channel and multi-reference frame. Both theoretical analysis and experimental results show that our scheme can best utilize the feedback message to recover rapidly from packet loss. No additional delay is incurred and no coding efficiency loss is penalized.
