Adaptation Method for Video Streaming over HTTP/2

Abstract

HTTP streaming, which is currently based on the pull-based HTTP/1.1 protocol, has a tradeoff problem between overhead and adaptivity. We propose an adaptation method for adaptive streaming over the new HTTP/2 protocol, leveraging its server push feature. The method is based on a cost function that takes into account the number of pushed segments and the client buffer level. Experiment results show that the proposed method can improve the balance between the number of requests and buffer stability compared to existing methods.
