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.

Adaptive bitrate control for simultaneous content streaming

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.

Smoothing bit rate variations in the distribution of media content

A media stream delivery system encodes and fragments media streams into numerous media stream fragments maintained on fragment servers. Playlist information, media data, and bandwidth adaption data is provided as box information with media stream fragments to reduce the number of client requests required to begin playback or perform a channel change. A client no longer needs to make separate requests for bandwidth adaptation data, media data, or playlist information. Playback can begin as soon as sufficient media stream fragments are received.

Enhanced startup and channel change for fragmented media stream delivery

A content server is configured to buffer and transmit numerous live media streams to individual devices. The content server analyzes characteristics associated with the live media streams to determine timing and sequence number information. Other characteristics such as network congestion metrics, device buffer usage metrics, etc., can also be evaluated. Combined peak transmission times are determined to allow packets designated for transmission at a bandwidth usage peak to be transmitted earlier in time. Earlier packets are shifted even earlier as sequence numbers allow. This evens out bandwidth usage rates and allows improved live media stream transmission.
