41、tionISO/IEC 16500 defines the minimum tools and dynamic behavior required by digital audio-visual systems forend-to-end interoperability across countries, applications and services. To achieve this interoperability, it definesthe technologies and information flows to be used within and between the m
42、ajor components of generic 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 (
43、non-physical) information-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 electricalcharacterist
44、ics. Accessible reference 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 provid
45、es a vocabulary and a 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 a
46、long with the normative 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 gi
47、ven 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 strict sets of Applications, Functionalities and Technologies which al

49、ompliance document for contour implementations.ISO/IEC 16500-4 (DAVIC 1.3.1a Part 8) defines the toolbox of technologies used for lower layer protocols andphysical interfaces. The tools specified are those required to digitize signals and information in the Core Networkand in the Access Network. Each tool is applicable at one or more of the reference points specified within theDelivery System. In addition a detailed specification is provided of the physical interfaces between the NetworkInterface Unit and the Set Top Unit
