Abstract
Examples methods and apparatuses including a statistical multiplexer (statmux) system with multiple channel rate control are described herein. The statmux system includes a rate controller, multiplex control unit and a plurality of encoders. An encoder of the plurality of encoders may be configured to provide a respective encoded bitstream of encoded coding units. The rate controller may buffer respective coding units of at least two of the plurality of channels based on statistical information from the plurality of encoders. The multiplex control unit may adjust multiplexing instructions for multiplexing the plurality of channels based on statistical information from the plurality of encoders, and may provide feedback to the rate controller based on the adjusted multiplexing instructions. The rate controller may provide a quality parameter to the plurality of encoders having a value based on the amount of buffered coding units and the feedback from the multiplex control unit.
