摘要：
In this paper, we present a novel scheme to deliver the scalable video over priority network. Firstly, we describe the background on the scalable video transmission over the network and the motivation of this research. Secondly, a new scheme is proposed, covering bitstream classification, prioritization and packetization. Thirdly, we present a simple and effective mechanism of rate control and adaptation by selectively dropping packet aiming to minimize the end-to-end distortion. We also describe a framework of transmission. Simulations show that our scheme is also effective to video multicast scenario.
