Abstract

This paper presents a self-regulated redundancy control scheme for high-bit-rate video transmission using packet-level forward-error-correction (FEC) codes over error-prone wireless networks. The effectiveness of FEC on video is obtained by regulating its redundancy cost to balance that tradeoff of bandwidth utilization and FEC efficiency based on channel status, temporal dependency of video frames, and network congestion level Experimental results show the proposed scheme maintains the desired quality-of-service ( oS) control over unloaded networks with the realistically measured wireless loss trace in 802.11b WLAN and over loaded networks, the adverse effect of FEC efficiency due to blindly increasing redundancy can be reduced to achieve the better video quality.
