Abstract

Based on the layered video streaming technique, we proposed a proxy-based traffic flow control scheme that adjusts the presentation quality according to the currently available bandwidth, i.e., dropping/adding some video layers when the network situation gets congested/smooth. Additionally, the proposed traffic flow control provides layered video stream buffering control to smoothen video playout. A re-transmission technique is also adopted to reduce the lost possibility of some important video frames. With the proposed traffic flow control scheme, the coming server-proxy-client multimedia presentation systems can have a better bandwidth utilization and presentation quality.
