Abstract

We propose an efficient error protection technique for data-partitioned H.264 video in a capacity constrained network. Our scheme maximizes video quality by choosing the optimal point in the application layer and Medium Access Control (MAC) layer redundancy. We have shown that, in a capacity constrained network and highly lossy environment, neither Forward Error Correction (FEC) nor retransmissions alone can result in optimum performance. Instead, it is the combination of these two techniques that effectively reduces the overall loss.
