Adaptive Video Streaming over HTTP with Dynamic Resource Estimation
Thang, Truong Cong,Le, Hung T.,Nguyen, Hoc X.,Pham, Anh T.,Kang, Jung Won,Ro, Yong Man The Korea Institute of Information and Commucation 2013 Journal of communications and networks Vol.15 No.6
Adaptive hypertext transfer protocol (HTTP) streaming has become a new trend to support adaptivity in video delivery. An HTTP streaming client needs to estimate exactly resource availability and resource demand. In this paper, we focus on the most important resource which is bandwidth. A new and general formulation for throughput estimation is presented taking into account previous values of instant throughput and round trip time. Besides, we introduce for the first time the use of bitrate estimation in HTTP streaming. The experiments show that our approach can effectively cope with drastic changes in connection throughput and video bitrate.
