    摘要： Aspects of the subject disclosure may include, for example, obtaining data budget for a communication session, identifying video content associated with the communication session, and determining a group of segments associated with the video content. Further embodiments can include determining a segment size for each of the group of segments, identifying a base track for each segment of the group of segments based on the segment size for each segment of the group of segments and the data budget, and identifying a target track for each segment of the group of segments based on the base track for each segment of the group of segments, the segment size for each segment of the group of segments, and the data budget. Additional embodiments can include providing a request for the target track for each segment to a video content server over a communication network. Other embodiments are disclosed.

    摘要： Devices, computer-readable media, and methods for differential adaptive bitrate streaming based on scene complexity are disclosed. In one example, a method includes inferring, by a processor, a complexity of a scene contained in a first chunk of an adaptive bitrate streaming video, wherein the first chunk is a next chunk of the adaptive bitrate streaming video to be downloaded to an adaptive bitrate streaming video player, and wherein the complexity indicates a relative amount of spatial and temporal information contained in the scene, and selecting, by the processor, a first track from which to download the first chunk, wherein the first track is one of a plurality of tracks containing the first chunk, and wherein each track of the plurality of tracks encoded the first chunk at a different bitrate, and wherein a bitrate of the first track is proportional to the complexity of the scene as inferred.

    摘要： Aspects of the subject disclosure may include, for example, a method in which a data-budget aware video streaming rate adaptation system receives information including a total data budget and a target quality level for a video streaming session presenting a video program; the video program has a plurality of tracks each encoding video content and including video content segments for successive presentation. The method also includes determining a target track for each of the video content segments; providing to a video streaming system the target track for a next successive video content segment; calculating a remaining data budget based on the total data budget and current data usage; and dynamically adjusting, in accordance with the remaining data budget, the target track for each remaining video content segment. Other embodiments are disclosed.

    摘要： Aspects of the subject disclosure may include, for example, communicating with a source of streaming media, wherein the streaming media is variable bitrate encoded, wherein the streaming media comprises a first plurality of chunks, wherein each of the first plurality of chunks corresponds to a first portion of the streaming media, wherein the streaming media comprises a second plurality of chunks, wherein each of the second plurality of chunks corresponds to a second portion of the streaming media, wherein the streaming media comprises a third plurality of chunks, and wherein each of the third plurality of chunks corresponds to a third portion of the streaming media; obtaining, from the source, a first one of the first plurality of chunks; and determining which of the second plurality of chunks and third plurality of chunks to obtain. Other embodiments are disclosed.
