  • Publication number: 20240031629
    Abstract: A method for managing the encoding of a multimedia content stream distributed in dynamic mode to viewing devices according to a set of profiles comprising a plurality of multimedia data distribution profiles usable by the viewing devices for reception of the multimedia content stream is proposed. Usage statistics data for at least one of the multimedia data distribution profiles is obtained, the usage statistics data representing usage, by the viewing devices, of the multimedia data distribution profile for receiving the multimedia content stream. Based on the usage statistics data, the set of profiles are updated by excluding the multimedia data distribution profile from the set of profiles. Based on the updated set of profiles, a configuration of an encoder used for encoding the multimedia content stream distributed to the viewing device is determined. The encoding is updated according to the determined encoder configuration.

  • 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.
