Abstract: A media delivery service may include a media source, a proxy cache and one or more client devices. The media source may generate coded segments from an input media stream and develop a playlist identifying network locations of the segments. The media source may broadcast the coded segments and their storage locations to a proxy cache in a broadcast channel. The proxy cache may store successfully received coded segments and develop a mapping table identifying the segments' network locations. The client may request segments from the proxy cache based on the received playlist form the media source. If the proxy cache does not store a requested segment, it may so notify the client and the client may request the segment from the media source.

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: Techniques are disclosed for measuring propagation delay of a media distribution system based on content output by rendering devices. An output from an output device of the media distribution system may be captured and a token may be detected from the captured content. A timecode may be derived from the detected token. The system's propagation delay may be determined from the derived timecode and may provide a basis to analyze system delays and other processing artifacts. In this manner, propagation artifacts may be estimated between multiple rendering devices that lack controls to synchronize their operation.

Abstract: An embodiment of a method of requesting and receiving a media stream can include, as performed by a computing device, responsive to a control input to control an enhanced playback mode for a media stream, determining a video frame to display in the enhanced playback mode of the media stream; requesting the determined frame from a media source over at least one connection between the computing device and the media source; predicting a second video frame for the enhanced playback mode; and requesting the predicted second frame from the media source over the at least one connection before receiving the determined video frame over the at least one connection.
