Methods and apparatuses including a statistical multiplexer with multiple channel rate control

A non-transitory computer-readable medium encoded with instructions comprising instructions that, when executed by one or more processing units, cause the one or more processing units to:

• adjust multiplexing rates at a multiplexer based on statistical information corresponding to buffered coding units received by the multiplexer from the plurality of channels;
• provide feedback to an output buffer based on the adjusted multiplexing rates;
• adjust a level of the output buffer based on the statistical information corresponding to the buffered coding units received from the plurality of channels and the feedback;
• and
• provide respective quality parameters to a plurality of encoders, wherein the quality parameters have values based, at least in part, on the feedback.

A method, comprising:

• buffering encoded coding units from a plurality of channels using a rate controller;
• adjusting multiplexing rates at a multiplexer based on statistical information corresponding to the buffered encoded coding units received by the multiplexer from the plurality of channels;
• providing feedback to an output buffer based on the adjusted multiplexing rates;
• adjusting a level of the output buffer based on statistical information corresponding to the buffered encoded coding units received from the plurality of channels and the feedback;
• and
• providing respective quality parameters to a plurality of encoders, wherein the quality parameters have values based, at least in part, on the feedback.
