  • Dynamic statmux video bandwidth determination
    Patent number: 11140429
    Abstract: Techniques for dynamic video bandwidth determination are described. An exemplary method includes receiving an indication of a desired total bitrate for a multiple program transport stream (MPTS), the MPTS having at least two programs; receiving non-video content from two or more encoders; buffering video content during a determination of available video bandwidth; and determining an amount of the desired total bitrate to be the available video bandwidth by: for each active encoder, determining a non-video bitrate over a first time period for each encoder using a sliding window based on a statistical measurement, summing the determined non-video bitrates for the active encoders to get a total non-video bitrate, subtracting the total non-video bitrate from the desired total bitrate to get an available video bandwidth, and allocating the available video bandwidth amongst the two or more encoders.
