A novel packet loss recovery for video stream transmission over networks

Transmitting high-quality, real-time interactive video over lossy networks such as Internet and wireless networks is very challenging, because of limited bandwidth and high packet loss rates. The loss of packets in a video frame leads not only to reduced quality of that frame, but also results in the propagation of that distortion to successive frames. We present a novel error recovery scheme based on a Solomon-like code scheme with only XOR operations for recovering lost packets. The simulation results indicate the advantage of our scheme over other erasure-resilient coding scheme.
