Patent number: 11277649Abstract: 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.Type: GrantFiled: September 4, 2019Date of Patent: March 15, 2022Assignees: AT&T INTELLECTUAL PROPERTY I.

Patent number: 11093315Abstract: Systems and methods for detecting a fault or model mismatch are disclosed. A system includes a processor, a memory, and one or more sensors. The sensors may detect data associated with an electronic device. The memory may store processor executable instructions to: compute T2 and Q statistics, over a time period, and apply a model mismatch and fault detection logic based on the T2 and Q statistics. The model mismatch and fault detection logic may: count consecutive instances where a T2 statistic exceeds a T2 threshold via a T2 counter, update a probability of fault based on the T2 counter, count consecutive instances where a Q statistic exceeds a Q threshold via a Q counter, update a probability of model mismatch based on the Q counter, and detect one of a fault or a model mismatch based on a probability of fault threshold and a probability of model mismatch threshold.Type: GrantFiled: March 22, 2019Date of Patent: August 17, 2021Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., University of ConnecticutInventors: Donald McMenemy, Weiqiang Chen, Ali M. Bazzi, Krishna R. Pattipati, Shailesh N. Joshi

Publication number: 20210067818Abstract: 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.Type: ApplicationFiled: September 4, 2019Publication date: March 4, 2021Inventors: Subhabrata Sen, Krishna R.
