Video coding for Internet and push-pull communication

Internet communication has been growing rapidly from simple emails and file transfers to sophisticated streaming video and audio. Compared with more traditional means of communications, Internet communication has its own characteristics. Therefore, video coding for Internet streaming has different requirements. In order to understand Internet communication, we need to develop a push-pull communication model. This paper formulates the problem of video coding for Internet communication as an optimization problem over an interval of bitrate. It proposes an approach to solving this problem. This paper is also an attempt to understand the push-pull communication model.
