Robust error control for scalable video streaming over Internet

This paper proposes a novel robust framework for scalable video over Internet. The main contribute of our work is that a simplified rate-distortion theory is specially developed for scalable bit-stream over the network and the corresponding bit allocation is presented to determine the sets of the channel rate for each video layer. Compared with the traditional iterative optimal bit allocation with complexity O(n (L)) time, simulations show that our scheme achieves high quality video transmission with much less complexity O(L x n) time, only no more than 0.2dB munder different network conditions (different bandwidth and different packet loss case). Besides, our error control scheme can be naturally combined with congestion control and error resilient techniques to enhance the performance of the overall system.
