Abstract: 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.

Abstract: 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.
