Abstract

Scalable video transmission is requried to transmit video over bandwidth limited channel like the Internet. However, previous scalable video transmission schemes which are based on static priority layer/slice encapsulation did not provide an algorithm to optimally choose parameters and/or required changes in the standard network protocol. The objective of this paper is to develop a new scalable video transmission scheme which can transmit stored video with low bandwidth requirement and eliminate the underflow/ overflow at client to ensure QoS. The main contributions in our scheme are: parameters are chosen based on the bit rate and burstiness of video, video frames are priority encapsulated and dropped dynamically by the server and/or network depending on the network congestion, the need for decoder/encoder combination at the server is eliminated, and no major changes are required in the standard network protocol. An analytical model is developed to determine the performance and quality of service offered by our proposed scheme as the function of the network size, network congestion level, and video burstiness. Results show that our scheme requires low bandwidth as a function of network size, network congestion level and video burstiness.
