Advanced contributions in HTTP adaptive streaming

Abstract : HTTP adaptive streaming is a recent topic in multimedia communications with on-going standardization activities, especially with the MPEG-DASH standard which covers on demand and live services. One of the main issues in live services deployment is the reduction of various latencies, the initial delay before the playback and the overall end-to-end latency. In this thesis, we address the problem of these latencies in live DASH streaming. First, we review the causes of startup delay in DASH and common strategies used to reduce this delay. We propose a new method based on HTTP/1.1 and compatible with existing caching and delivery infrastructures for reducing the initial setup of an MPEG-DASH session. Second, we investigate the major contributor components to the end-to-end latency. We propose a complete novel low latency live DASH streaming system. Third, we show how such a low latency live DASH system can be used to enable combined broadcast and broadband services while keeping the client buffering requirements on the broadcast link low. Our proposed approach insures two functionalities: synchronization of both contents delivered through different distribution networks and keeping the client buffering requirements on the broadcast link low.
