In cellular networks, however, the unreliable wireless channel leads to two major problems. Poor channel states degrade video quality and interrupt the playback when a user cannot sufficiently fill its local playout buffer: buffer underruns occur. In contrast, good channel conditions cause common greedy buffering schemes to buffer too much data. Such over-buffering wastes expensive wireless channel capacity. Assuming that we can anticipate future data rates, we plan the quality and download time of video segments ahead. This anticipatory download scheduling avoids buffer underruns by downloading a large number of segments before a drop in available data rate occurs, without wasting wireless capacity by excessive buffering.We developed a practical anticipatory scheduling algorithm for segmented video streaming protocols (e.g., HLS or MPEG DASH). Simulation results and testbed measurements show that our solution essentially eliminates playback interruptions without significantly decreasing video quality."}],"has_accepted_license":"1","status":"public","year":"2015","citation":{"bibtex":"@inproceedings{Dräxler_Blobel_Dreimann_Valentin_Karl_2015, title={SmarterPhones: Anticipatory Download Scheduling for Wireless Video Streaming}, DOI={<a href=\"https://doi.org/10.1109/NetSys.2015.7089073\">10.1109/NetSys.2015.7089073</a>}, booktitle={Proceedings of the 2nd International Conference on Networked Systems (NetSys)}, author={Dräxler, Martin and Blobel, Johannes and Dreimann, Philipp and Valentin, Stefan and Karl, Holger}, year={2015}, pages={1--8} }","short":"M.
