A three level adaptive video streaming framework over LTE
Satish Kumar, Santhosh Sriram, Arnab Sarkar, Arijit Sur · 2016
The ever increasing demand for high bandwidth, low latency multimedia applications on mobile devices is set to pose a considerable challenge on the bandwidth allocation and multiplexing mechanisms in LTE and future wireless networks. This paper proposes a low overhead Scalable Video Coding (SVC) based dynamic adaptive streaming framework (called TLS-AV) which attempt to maintain a minimum satisfactory Quality of Experience (QoE) for all end users even during transient network overloads. Two fast and efficient radio resource allocation heuristics namely, the TLS-AV Water-Filling Heuristic (TWH) and TLS-AV Balanced Water-Filling Heuristic (TBWH) have been implemented over the proposed framework. Experimental results reveal that both the developed heuristics are able to restrict packet loss rate below ~ 10% while simultaneously achieving high video qualities and fairness among the transmitted qualities of video flows, on average.
