A new architecture of sender-adaptive and receiver-driven layered multicasting for video over Internet is presented in this paper. This architecture optimizes the overall performance by making the sender collaborate with the receivers. The statistical characteristics of bandwidth and packet loss ratio of all the receivers, the network temporal variation of each receiver, and the rate-distortion relation of the video codec have been taken into account. Techniques of network resource allocation, scalable video coding, FEC and pseudo-ARQ are also integrated in this scheme. Moreover, we introduce a new mathematical framework named Q-Space Model & Optimization to generalize the multicasting approach. Simulation results demonstrate the effectiveness of our scheme
