What is the MPEG-4 delivery layer?

Standard: 
Part name: 

It is a generic abstraction for delivery mechanisms (computer networks, etc.) able to store or transmit a number of multiplexed elementary streams or FlexMux streams. To allow for maximum flexibility for service creation and application design, it is not specified by MPEG-4. The interface, however, to the delivery layer is well defined, thus allowing transmission of MPEG-4 content over any type of transport layer facility (e.g., ITU-T Recommendations H.22x, MPEG-2 Transport Stream, IETF RTP).
