Abstract
A method of streaming media may include opening a single connection between a client device and a media source; requesting a first media segment of a media stream corresponding to selected tier of a media title over the single connection; determining a download bitrate of the single connection; comparing the download bitrate to a predetermined bitrate of the media title; and in response to determining that the download bitrate is less than the predetermined bitrate, opening a plurality of connections between the client device and media source. The predetermined bitrate may be a predetermined bitrate of a next higher bitrate tier in a group of tiers containing the selected tier when the selected tier is not a highest bitrate tier in the group, and a predetermined bitrate of the selected tier otherwise. The method may further include, in response to determining that an aggregate download bitrate of the plurality of connections is less than a multiple of a download bitrate of an individual one of the connections, closing some of the plurality of connections so that only the individual connection remains.
