Multi-path Forward Error Correction Control Scheme with Path Interleaving

Abstract

Several research studies have been devoted to improving the reliability and performance of the Internet by utilizing redundant communication paths. Multihoming and overlay networks are two main streams in this area of research which attempt to leverage redundant connections of the Internet for increased reliability and performance. Furthermore, the quality of video transmission can be improved when path diversity is combined with the error control scheme such as forward error correction. Nevertheless, in the general networks, losses are burst due to network congestion and channel errors in wireless communication and this property of burst losses decreases the efficiency of FEC. In this thesis, a novel multi-path FEC control scheme with path interleaving is proposed for improving the quality of video transmission. Our scheme aims at dispersing the burst losses to different FEC blocks and therefore the efficiency of FEC can be improved. The experimental results shows that compared to the traditional multi-path FEC schemes, the experimental results show that the proposed scheme achieves better performances in terms of packet loss rate and video PSNR.
