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

47、ence points are used to determine and demonstrate compliance of a digital audio-visual subsystem with this international standard.A summary of each part follows.ISO/IEC 16500-1 (DAVIC 1.3.1a Part 2) defines the normative digital audio-visual systems technical framework.It provides a vocabulary and a

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

49、ve protocols needed to support the systemsbehavior. 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
