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.

Abstract: Methods and apparatus are described for delivering streams of media content in ways that smooth out the peaks that might otherwise occur due to the bit rate variations that result from encoding of the media content. This is accomplished by controlling the timing of the transmission of packets of the encoded media content.
