A robust and flexible wireless video multicast system with the H.264 scalable video coding (SVC) coding format and network coding (NC) is proposed in this work. The system enables efficient video streaming to heterogeneous receivers in packet erasure channels. NC is used to simplify erasure protection as well as the complexity of multicast tree construction and maintenance. It is shown by simulation results that the proposed solution improves PSNR over the traditional video multicast with error correction codes (ECC) in store-and-forward networks.
