Enhancing performance of rapid channel changes and other playback positioning changes in adaptive streaming

摘要

Content is received within a network by a content receiver based upon fetch requests by the content receiver to a content source, where the fetch requests for content are based upon a first adaptation logic scheme to fill a buffer of the content receiver at a selected rate and to download segments of content at selected encoding rates. A network priority is detected at the content receiver that includes an observed download rate at the content receiver that is greater than a fair share rate for other content receivers in the network. Fetch requests for content are revised in response to detection of the network priority, where the revised fetch requests are based upon a priority adaptation scheme that results in at least one of filling the buffer at a faster rate and downloading segments of content at higher encoding rates compared with the first adaptation logic scheme.

主权项

1. A method comprising:
receiving content within a network at a content receiver that is communicated from a content source based upon fetch requests by the content receiver, wherein the fetch requests for content are based upon a first adaptation logic scheme to fill a buffer of the content receiver at a selected rate and to download segments of content at selected encoding rates; detecting a network priority at the content receiver, wherein the network priority comprises an observed download rate at the content receiver that is greater than a fair share rate for other content receivers in the network; and revising fetch requests for content in response to detection of the network priority, wherein the revised fetch requests are based upon a priority adaptation scheme that results in at least one of filling the buffer at a faster rate and downloading segments of content at higher encoding rates in relation to the first adaptation logic scheme.
