To achieve this interoperability, it definesthe technologies and information flows to be used within and between the major components of ge
45、neric digitalaudio-visual systems. Interoperability between these components and between individual sub-systems is assuredthrough specification of tools and specification of dynamic systems behavior at defined reference points. Areference point can comprise one or more logical (non-physical) informa
46、tion-transfer interfaces, and one or morephysical signal-transfer interfaces. A logical interface is defined by a set of information flows and associatedprotocol stacks. A physical interface is an external interface and is fully defined by its physical and electricalcharacteristics. Accessible refer

48、 Systems Reference Model, which identifies specific functional blocks andinformation flows, interfaces and reference points.ISO/IEC 16500-2 (DAVIC 1.3.1a Part 12) defines system dynamic behavior and physical scenarios. It details thelocations of the control functional entities along with the normati

It is structured as a set of protocol walk-throughs, or “Application Notes”, that rehearse both the steadystate and dynamic operation of the system at relevant reference points using specified protocols. Detaileddynamics are given for the following scenarios: video on demand, switched video broadcast, interactivebroadcast, and internet access.ISO/IEC 16500-3 (DAVIC 1.3.1a Part 14) provides the normative definition of DAVIC Technology Contours.These are
