Abstract: An alternative design is presented and analyzed for providing a just in time video such that even though multiple variants are advertised to a client, the bit streams need not be present. Instead, the videos are generated just in time when a client requests them. At a given time instant, only that video stream is generated which corresponds to the bit rate requested by the client and streams with other bit rates advertised in the manifest file are not generated. This saves storage cost and/or lowers the numbers of transcoders needed to generate full manifest file all the time. Two different architectures are presented and analyzed. Analysis of impacts of the encoding/transcoding speed on the behavior of such a system is presented and used in designing an optimal solution based on desired price and performance points.

Abstract: A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys.

Abstract: A method is provided for multiplexing video services with data services in a constrained delivery pipeline. A soft upper bound for the video data bandwidth for a current schedule window BWvideosoft(i) is generated, wherein the soft upper bound for the video data bandwidth such that an average video data bandwidth over a time period T is no greater than a hard upper bound for the video data bandwidth BVvideo. The video data is then multiplexed with the other data according to the soft upper bound for the video data bandwidth BWvideosoft(i).

Abstract: In embodiments of broadcast content to HTTP client conversion, a client converter receives video content as an input of broadcast content data streams from a content distribution system. The client converter can join a content data stream of the broadcast input, and convert the content data stream to unicast HTTP data, such as video content segments that are buffered for communication to a client device or to a media player of a client device. An HTTP server of the client converter can then communicate the unicast HTTP data to the client device or to the media player for playback of the video content.
