Abstract

Content download technology, in which a network-based video scheduled to be played at a particular time is identified, and multiple sources from which the network-based video is available for downloading are identified. An initial source from which to download the network-based video is selected from among the multiple sources, and a first process to download the network-based video from the initial source is initiated. Progress of the download of the network-based video is monitored. When an estimated amount of time remaining for the download of the network-based video from the initial source to complete does not enable viewing of the network-based video at the particular time without interruption, an alternative source from which to download at least a portion of the network-based video is selected from among the multiple sources, and a second process to download at least the portion the network-based video from the alternative source is initiated.
