    摘要： A processing system including at least one processor may obtain a selection of a desired perceptual quality for a video and selects a first video chunk from among a first plurality of video chunks, wherein the first plurality of video chunks is associated with a first time block of the video, wherein the selecting is based upon a manifest file of the video, wherein each video chunk of the first plurality of video chunks is associated with a respective perceptual quality and a respective encoding bitrate, wherein the first video chunk is part of a subset of the first plurality of video chunks for which the respective perceptual quality matches the desired perceptual quality within a predefined threshold tolerance, and wherein the respective encoding bitrate of the first video chunk is lower than a highest encoding bitrate associated with the subset of the first plurality of video chunks. The processing system may obtain the first video chunk from a server and store the first video chunk in a buffer.

    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： Concepts and technologies for adaptive cloud offloading of mobile augmented reality are provided herein. In an embodiment, a method can include receiving, by an augmented reality system, an acquired image frame captured by an acquisition device. The acquired image frame can indicate a plurality of acquired image frame parameters. The method can include determining, by the augmented reality system, a plurality of augmented reality process instances. The method can include determining a plurality of local feature extraction time estimates based on the plurality of acquired image frame parameters, where a local feature extraction time estimate is created for each of the plurality of the augmented reality process instances. The method can include obtaining a network condition measurement, and generating a plurality of offload commands based on the network condition measurement and at least one of the plurality of local feature extraction time estimates.

    摘要： Aspects of the subject disclosure may include, for example, embodiments for capturing video content with a camera. The camera is communicatively coupled to the device. Further embodiments include obtaining a network condition of a communication network. Additional embodiments include determining a network criterion according to the network condition. Also, embodiments include calculating a threshold according to the network criterion. Further embodiments include adjusting the video content in response to determining network criterion resulting in adjusted video content. Additional embodiments include determining that a first portion of the adjusted video content satisfies the threshold. Also, embodiments include transmitting the adjusted video content to a video content server over the communication network. Other embodiments are disclosed.
