UEP Network Coding for SVC Streaming

摘要

In this paper, we propose an optimized unequal error protection (UEP) network coding for scalable video coding (SVC). First, we introduce packet-level UEP network coding schemes which encode packets with different selection probabilities according to the priorities of video layers. Secondly, we explain how to prioritize the packet selection probability using distortion degree. The distortion degree accounts for the layers as well as group of pictures (GOP). Finally, experiment results demonstrate the performance of our proposed UEP network coding compared to other existing network coding methods in terms of decoding probability and peak signal to noise ratio (PSNR).
