Dash in mobile networks and services
Thomas Stockhammer, Michael G. Luby · 2012
This paper provides an overview on the challenges of mobile video streaming focusing on overload situations, variable bandwidth and power consumption issues. Dynamic Adaptive Streaming over HTTP (DASH) is introduced as an enabler to address a significant portion of these challenges. The applicability of the formats to 3G and 4G unicast distribution is provided. Also the applicability of DASH formats for multicast distribution in MBMS is shown. Finally, the usage of DASH in hybrid unicast/multicast is introduced to provide a flexible extension to support different business and delivery models. An outlook to ongoing and future work is provided.
