摘要

In end-to-end networks, the burst losses caused by network congestion and wireless channel errors reduce the efficiency of the forward error correction (FEC) scheme. Although different control techniques are designed to enhance the loss recovery ability, the resulting FEC processing latencies may increase the end-to-end delay to violate the stringent constraints of delay sensitive video communications. Therefore, this paper presents a FEC enhancement scheme to achieve a tradeoff between end-to-end delay and the FEC loss recovery performance. The proposed scheme consists of 1) an adaptive block size control mechanism to reduce the FEC processing delay and 2) the interleaving technique to improve the error correction capacity of small block sizes. The experimental results show that the proposed scheme significantly improves the video streaming quality in lossy channels for delay-sensitive video.
