Abstract: 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.

Abstract: Devices, computer-readable media, and methods for selecting a video chunk from among a plurality of video chunks associated with a first time block of a video in accordance with a designated perceptual visual quality are disclosed. For instance, a processing system including at least one processor may obtain a selection of a designated perceptual visual quality for a video, select a video chunk from among a plurality of video chunks associated with a first time block of the video, based upon a manifest file of the video, where the video chunk is selected in accordance with the designated perceptual visual quality, and where each of the plurality of video chunks is associated with a respective perceptual visual quality. The processing system may further obtain the video chunk from a server and record the video chunk in a buffer.
