This paper provides an overview of applying Network Coding (NC) for robust video streaming in an erasure network. Traditional methods of video erasure protection in a store-and-forward (S/F) network are evaluated against the NC-enabled network. Both the benets and disadvantages of using NC for robust video streaming are included in this discussion. While NC naturally improves the throughput of data multicast by ratelessly generating redundant packets within the network , NC does not facilitate video error concealment with degraded video quality. In the following discussion, we consider the requirements for robust video streaming in broadcast, multicast, and video conferencing. We also discuss several solutions to apply NC to the above application scenarios.
