  • Patent number: 11729109
    Abstract: A method provides for delivering video content from a server to a plurality of media devices is disclosed that distributes accurately excess bandwidth. The method includes: determining, by the server, the bandwidth to allocate to each of the plurality of media devices using a hypertext transfer protocol-based live streaming client model or a need parameter vector and/or measured bandwidth limitations associated with each of the plurality of media devices and providing the allocated bandwidth to each of the plurality of media devices, wherein the video content is transmitted in a plurality of segments from the server, and wherein each segment is transmitted at a bitrate that may vary from segment to segment.

  • Patent number: 11677799
    Abstract: A method for distributing video content from a server to a plurality of media devices is provided allowing adaptive bit rate encoding to better utilize bandwidth. The method includes: determining, by the server, the bandwidth to allocate to each of the plurality of media devices using a hypertext transfer protocol-based live streaming client model or a need parameter vector, refining this determination by utilizing client feedback regarding client buffer level and playback state, client hardware capabilities, and client internally measured download rate, and providing the allocated bandwidth to each of the plurality of media devices; wherein the video content is transmitted in a plurality of segments from the server, and wherein each segment is transmitted at a bitrate that may vary from segment to segment.

  • Patent number: 10349098
    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).

  • Patent number: 10044466
    Abstract: Methods and systems are described for adaptively transmitting streaming data to a client. In one embodiment, the method comprises receiving, in a server, a request for a data asset from the client, transcoding at least a segment of the data asset according to initial transcoding parameters, transmitting a first fragment of the transcoded segment of the data asset from the server to the client over a communication channel, generating an estimate of a bandwidth of the communications channel at least in part from information acknowledging reception of at least the first fragment of the transcoded segment of the data asset by the client, generating adaptive transcoding parameters at least in part from an estimate of a bandwidth of the communications channel, the estimate generated at the server, transcoding a further segment of the data asset according to the adaptive transcoding parameters, and transmitting the further segment of the data asset.
