What does MPEG-4 demultiplexing mean?

Part name: 

The demultiplexing stage retrieves the individual elementary streams that are usually interleaved for transmission or storage. It is a functionality that is not seen as part of MEPG-4 Systems. It is hidden in the delivery layer. MPEG-4 ESM just deals with the demultiplexed, usually still SL-packetized, elementary streams that are accessible through the DMIF application interface (DAI). In order to support upstream information, a receiving terminal might also incorporate multiplexing facilities.
