1. A computer-implemented method comprising:

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; and

for each second time period, adding to an end of the sliding window non-video bitrate tracker a number of non-video bits in that second time period for the non-video content and sliding the sliding window non-video bitrate tracker by the second time period to remove an oldest non-video bits count in the sliding window non-video bitrate tracker, and

choosing a maximum number of non-video bits in the sliding window non-video bitrate tracker to generate the non-video bitrate for the active encoder,

summing the generated 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.

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,
