Optimizing HTTP-based Adaptive Video Streaming for wireless access networks

In this paper, we propose an optimization algorithm called Intelligent Bitrate Switching-based Adaptive Video Streaming (ISAVS) to address the key issue of bitrate switching in HTTP-based adaptive video streaming. Our proposed solution can provide the best possible video quality to users with minimum replay interruption, which is reported as one of the key video quality issues of on-line video streaming over wireless access networks. While the optimization algorithm is based on IIS Smooth Streaming architecture [1], it can be easily applied by other proposed approaches, such as Adobe Flash Dynamic Streaming, and Apple HTTP Adaptive Bitrate Streaming. Simulations show that our optimization algorithm selects the best video bitrate according to channel condition and the amount of video stream buffered in the client to provide viewers the best possible quality while reducing the number of interruptions.
