Abstract

The current server-client 2-stage-based multimedia transmission configuration is to be changed to a server-proxy-client 3-stage-based one when the broadband Internet becomes true. The traffic flow control scheme becomes different for the coming 3-stage-based multimedia transmission. In this paper, we propose a 3-stage traffic flow control scheme for transmitting multimedia data over the server-proxy-client transmission architecture. Based on the layered video streaming technique, the proposed traffic flow control scheme adjusts the presentation quality according to the currently available bandwidth, i.e., dropping/adding some video layers when the networking situation gets congested/smooth. Additionally, the proposed traffic flow control scheme provides layered video stream buffering control to smoothen video playout and adopts a re-transmission technique to reduce the loss possibility of some important video frames. With the proposed traffic flow control scheme, the coming 3-stage multimedia presentation systems can have a better optimization of bandwidth utilization and presentation quality over a broadband Internet environment.
