Abstract: An embodiment of a method of requesting a plurality of media streams can include, as performed by a computing device, receiving a control input to control a playback function of at least one of the plurality of media streams, determining a download bandwidth between the computing device and a media source on a network, classifying the at least one of the plurality of media streams based on the control input and total download bandwidth, and sending a plurality of requests for the plurality media streams over a single connection to the media source, wherein at least one of an order or a content of the requests is based on the classification. The sending of the media stream requests can utilize at least one of a server-side protocol for multiplexing media streams over a single connection or one or more of HTTP pipelining or HTTP range requests over a single connection.

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.

Abstract: Methods and systems for switching between media streams can use a comparison of an average bandwidth for a new stream to an observed bit rate for an existing stream in order to determine whether to switch to the new stream. A check on the amount of data buffered for the existing stream can also be performed in order to determine whether a system should switch to the new stream.
