  • Patent number: 11671665
    Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for adaptive bitrate control for simultaneous content streaming. Example methods may include determining, by an adaptive bitrate controller, a first bits per pixel value associated with a first content stream at a device at a first timestamp, determining a second bits per pixel value associated with a second content stream at the device at the first timestamp, and generating a bits per pixel ranking using the first bits per pixel value and the second bits per pixel value. Some methods may include determining a bitrate improvement priority based at least in part on the bits per pixel ranking, and causing a request to improve a bitrate of the first content stream to be approved.

  • Patent number: 11671336
    Abstract: There is provided a method for adaptive bitrate (ABR) adjustments in an IP network before making upshift of ABR level of media streams like video for live Over the Top (OTT) distribution. Example methods may include initiating, at a first time interval, probing of the IP network to determine if a first candidate bitrate is applicable, where the first candidate bitrate is greater than a preset bitrate of a client device data stream, determining that the candidate bitrate is applicable, increasing a transfer bitrate of the client device data stream, and initiating, at a second time interval, probing of the IP network to determine if a second candidate bitrate is applicable, where the second candidate bitrate is greater than the first candidate bitrate.

  • Patent number: 11206198
    Abstract: There is provided a method for adaptive bitrate (ABR) adjustments in an IP network before making upshift of ABR level of media streams like video for live Over the Top (OTT) distribution. The invention is based on before upshifting of a current ABR level to a higher ABR level for one or more client devices, probing the network system with a higher bitrate of the data stream provided by e.g. replicating data in the data stream, and monitoring network conditions during probing. Based on the probing it is determined if the available resources in the network are sufficient to sustain an upshift of ABR-level for the client device.
