Adaptive Multi-Connection DASH Scalable Video Coding for Wireless Area Networks

Abstract

Dynamic Adaptive Streaming over Hypertext Transfer Protocol HTTP (DASH) has gained a significant momentum for multimedia streaming due to its ability in crossing firewalls and availability of infrastructure. In the mean time, Scalable Video Coding (SVC) is building a similar momentum as it enables efficient media storage and caching. In this work, we identify the main components of adaptive SVC-DASH client and propose a streaming heuristic over dynamic multiple connections. The proposed algorithm is experimentally tested under different connection and link configurations. Our results show that the algorithm successfully achieves interruption free streaming under all the tested BandWidth and link configurations. Additionally, the usage of multiple connections results in noticeable improvements in the achieved streaming quality for large link delays.
