Abstract

Application Layer Forward Error Correction AL-FEC with rateless codes can be applied to protect the video data over lossy channels. Expanding Window Random Linear Codes EW RLCs are a flexible unequal error protection fountain coding scheme which can provide prioritized data transmission. In this paper, we propose a system that exploits systematic EW RLC for H.264-Advanced Video Coding AVC slice-partitioned data. The system prioritizes slices based on their PSNR contribution to reconstruction as well as temporal significance. Simulation results demonstrate usefulness of using relative slice priority with systematic codes for multimedia broadcast applications.
