摘要： A client device implements a streaming client and a proxy server. The proxy server intercepts one or more playlist requests from the streaming client directed to one or more network servers external to the client device. Responsive to interception of a sliding-window playlist request of a particular type, the proxy server generates a corresponding on-demand playlist request. The intercepted sliding-window playlist request and the corresponding on-demand playlist request are sent from the proxy server to the one or more network servers. The proxy server receives an on-demand playlist from the one or more network servers responsive to the on-demand playlist request, and generates a local copy of the on-demand playlist. A current version of the local copy of the on-demand playlist is subsequently provided by the proxy server to the streaming client responsive to interception in the proxy server of a request from the streaming client for the on-demand playlist.

摘要： A method comprises obtaining information characterizing multiple content streams comprising respective portions of content received from respective ones of a plurality of sources, obtaining positional information for the sources wherein the positional information indicates for each of the sources its current position in a set of possible positions relative to other ones of the sources, generating an additional content stream comprising selected portions of particular ones of the multiple content streams based at least in part on the positional information and a mapping between the content streams and the sources, and presenting the additional content stream to a user. The additional content stream may be generated so as to provide the user with a dynamic vantage point within a live event by switching between the selected portions of the particular ones of the multiple content streams, possibly as a function of input received from user equipment operated by the user.

摘要： A method comprises receiving content from a source, and generating multiple content streams each comprising the received content. Each content stream includes segments comprising respective portions of the received content. Different segmenting is utilized in generating respective ones of the content streams such that the segments in each of the content streams are offset in time relative to corresponding segments in the other ones of the streams. For example, generating the multiple content streams may comprise segmenting n content streams such that each content stream comprises segments of length Ts with corresponding segments in adjacent ones of the content streams being offset from one another by an offset Tg. Such an arrangement ensures that latency shift upon switching between one of the content streams and another content stream in a different set of multiple content streams at a client device can be limited to a value approximated by Tg.

摘要： A media player or other type of client device is configured to obtain a plurality of playlists for a given item of media content from one or more servers over a network. The playlists comprise at least a sliding-window playlist and an on-demand playlist for the given item of media content with each such playlist identifying a plurality of media segments of the given item of media content. The client device comprises a playback module configured to play back portions of the given item of media content utilizing respective ones of the sliding-window and on-demand playlists. A navigation state machine controls switching of the playback module between playback of media segments from the sliding-window playlist and playback of media segments from the on-demand playlist responsive to user navigation within a timeline of the given item of media content using one or more navigational controls.
