Abstract:
1. A method for statistical multiplexing of a plurality of data streams, comprising: communicating a bandwidth request message from each of a plurality of encoders to a second stage multiplexer; allocating available bandwidth at said second stage multiplexer based on said bandwidth request messages; communicating an allocated bandwidth message to each of said encoders which contains an allocated bandwidth for each encoder based on said allocating; encoding a data stream at each encoder in accordance with the allocated bandwidth for that encoder to provide an encoded data stream from each encoder; multiplexing a plurality of said encoded data streams at a first stage multiplexer to provide a multiplexed data stream at a constant data rate; and multiplexing at said second stage multiplexer a plurality of said multiplexed data streams from a plurality of said first stage multiplexers to provide a multiplexed transport stream.
