Mobile video streaming services are ubiquitous today and yet their real-world performance is still largely inconsistent, unpredictable, and uncontrollable, primarily due to mobile networks' inherent bandwidth fluctuations at both short and long timescales. With the rapid emergence of paid streaming services, picture and streaming qualities can no longer be an afterthought. This work develops a novel...
Current mobile video streaming is primarily delivered over HTTP. In addition to conventional web access logs, many service providers also log the data usage for billing and analytics purposes. This work exploits these vast amount of bandwidth trace data to enable the provisioning of streaming performance and video quality guarantees in adaptive mobile video streaming. We develop a post-streaming analysis...
Adaptive video streaming is an essential tool for improving the performance of video delivery over mobile networks. By dynamically switching between different bit-rate versions of the same video, adaptive video streaming can compensate for and adapt to the ever-changing network conditions inherent in today's 3G/4G networks. However, existing adaptive streaming algorithms, both academic and commercial...
