摘要:
A system and method for multiple channel statistical re-multiplexing preferably includes a plurality of encoders each coupled to a respective channel and producing a compressed channel, a statistical re-multiplexer and a transport medium. The statistical re-multiplexer preferably has a plurality of inputs and an output for combining the input compressed channels into a single output bit stream. The statistical multiplexer further includes a plurality of de-multiplexers and a scheduler & multiplexer having a plurality of buffers, a scheduling table and a controller. Each of the buffers receives and stores compressed data from a respective encoder for a respective channel. The output of each buffer is coupled to a respective de-multiplexer that re-encodes the compressed channel in response to control signals from the scheduler & multiplexer. The scheduler and multiplexer receive the re-multiplexed streams from the re-multiplexers, and combine them into a single stream that matches the bandwidth of the physical transport medium.
