Cloud-assisted buffer management for HTTP-based mobilevideo streaming

Abstract

This paper studies a cloud-assisted procedure to improve the user's Quality of Experience (QoE) in HTTP Adaptive Streaming (HAS) services. HAS delivers video streaming services following a client-server architecture and requires the client to originate repeated HTTP requests to download chunks of encoded video. In state-of-the-art systems, the client selects the actual chunk to be downloaded from a finite set of differently encoded video versions available at the server site, according to a client-based buffer management procedure.
