Overlay real-time video multicast system

Abstract

In this paper. we present an effective overlay real-time video multicast system over the Internet The proposed system effectively integrates overlay multicast technology and video compression technology Overlay multicast tree and target bit rate are determined to satisfy the given average delay constraint. and H263+ rate control is implemented to enhance the human visual perceptual quality Over the multicast tree Finally. experimental results are provided to show the performance of the proposed overlay video multicast system over the Internet
