Enhanced Adaptive FEC Based Multiple Description Coding for Internet Video Streaming over Wireless Network

This paper proposes a video streaming mechanism with packet recovery which extends the Enhanced Adaptive Forward Error Correction (EAFEC) scheme by involving Multiple Description Coding (MDC) with path diversity. The proposed mechanism transmits multiple video sub-streams along multiple disjoint paths, then recovers the sub-streams using EAFEC separately, and at last merges and reconstructs the whole video stream at the receiver. It provides resilience to packet loss and overcomes the defect in EAFEC method that it cannot recover the lost packets which should arrive at wireless access point. The simulation results show that the proposed mechanism performs better than EAFEC within narrow bandwidth varying from 0.01Mbps to 0.064Mbps reflecting in smaller packet loss rate and higher PSNR.
