  • Adaptive bitrate streaming techniques
    Patent number: 11431777
    Abstract: Devices, computer-readable media, and methods for providing a timeout for an adaptive bitrate streaming video chunk download are disclosed. For example, a processing system including at least one processor may determine a first bitrate for a first segment of a video program based upon an occupancy level of a video buffer of a device, request a first video chunk of the first segment encoded at the first bitrate, determine that the first video chunk is not received within a threshold of a duration of time after the requesting of the first video chunk, and request, responsive to the determining that the first video chunk is not received within the threshold of the duration of time, a second video chunk of the first segment encoded at a second bitrate that is lower than the first bitrate.
    Type: Grant

    Date of Patent: August 30, 2022
    Assignee: AT&T Intellectual Property I, L.P.
    Inventors: Mohammad Mahvash, Sassan Pejhan, Buu Kha, Garrett Newell
