Abstract
Examples of apparatuses and methods for pooling multiple channels into a multiple program transport stream are described herein. An example apparatus may include a statistical multiplexing (statmux) system coupled to a communication link. The statmux system includes a virtual buffer verifier (VBV) shifter and a plurality of encoders. The VBV shifter is configured to receive respective encoded bitstreams of encoded coding units from the plurality of encoders and to provide a plurality of encoded coding units to a common data pool. The VBV shifter is further configured to remove an encoded coding unit of the plurality of encoded coding units from the common data pool to be combined with other encoded coding units of the plurality of encoded coding units for transmission on the communication link based on a target bitrate.
