Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO/IEC 16500 may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

ISO/IEC 16500-9:1999(E)
Introduction
ISO/IEC 16500 defines the minimum tools and dynamic behavior required by digital audio-visual systems for
end-to-end interoperability across countries, applications and services. To achieve this interoperability, it
defines the technologies and information flows to be used within and between the major components of
generic digital audio-visual systems. Interoperability between these components and between individual sub-
systems is assured through specification of tools and specification of dynamic systems behavior at defined
reference points. A reference point can comprise one or more logical (non-physical) information-transfer
interfaces, and one or more physical signal-transfer interfaces. A logical interface is defined by a set of
information flows and associated protocol stacks. A physical interface is an external interface and is fully
defined by its physical and electrical characteristics. 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 provides a vocabulary and a Systems Reference Model, which identifies specific functional
blocks and information flows, interfaces and reference points.
ISO/IEC 16500-2 (DAVIC 1.3.1a Part 12) defines system dynamic behavior and physical scenarios. It details
the locations of the control functional entities along with the normative protocols needed to support the
systems behavior. It is structured as a set of protocol walk-throughs, or “Application Notes”, that rehearse
both the steady state and dynamic operation of the system at relevant reference points using specified
protocols. Detailed dynamics are given for the following scenarios: video on demand, switched video
broadcast, interactive broadcast, 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 allow compliance and
conformance criteria to be easily specified and assessed. This part of ISO/IEC 16500 contains the full details
of two contours. These are the Enhanced Digital Broadcast (EDB) and Interactive Digital Broadcast (IDB).
ISO/IEC 16500-3 specifies required technologies and is a mandatory compliance document for contour
implementations.
ISO/IEC 16500-4 (DAVIC 1.3.1a Part 8) defines the toolbox of technologies used for lower layer protocols
and physical interfaces. The tools specified are those required to digitize signals and information in the Core
Network and in the Access Network. Each tool is applicable at one or more of the reference points specified
within the Delivery System. In addition a detailed specification is provided of the physical interfaces between
the Network Interface Unit and the Set Top Unit and of the physical interfaces used to connect Set Top Boxes
to various peripheral devices (digital video recorder, PC, printer). The physical Delivery System mechanisms
included are copper pairs, coaxial cable, fiber, HFC, MMDS, LMDS, satellite and terrestrial broadcasting.
ISO/IEC 16500-5 (DAVIC 1.3.1a Part 7) defines the technologies used for high and mid-layer protocols for
ISO/IEC 16500 digital audio-visual systems. In particular, this part defines the specific protocol stacks and
requirements on protocols at specific interfaces for the content, control and management information flows.
ISO/IEC 16500-6 (DAVIC 1.3.1a Part 9) defines what the user will eventually see and hear and with what
quality. It specifies the way in which monomedia and multimedia information types are coded and
exchanged. This includes the definition of a virtual machine and a set of APIs to support interoperable
exchange of program code. Interoperability of applications is achieved, without specifying the internal design
of a set top unit, by a normative Reference Decoder Model which defines specific memory and behavior
constraints for content decoding. Separate profiles are defined for different sets of multimedia components.
ISO/IEC 16500-7 (DAVIC 1.3.1a Part 10) defines the interfaces and the security tools required for an
ISO/IEC 16500 system implementing security profiles. These tools include security protocols which operate
across one or both of the defined conditional access interfaces CA0 and CA1. The interface CA0 is to all
security and conditional access functions, including the high speed descrambling functions. The interface
CA1 is to a tamper resistant device used for low speed cryptographic processing. This cryptographic
processing function is implemented in a smart card.
ISO/IEC 16500-8 (DAVIC 1.3.1a Part 6) specifies the information model used for managing ISO/IEC 16500
systems. In particular, this part defines the managed object classes and their associated characteristics for
managing the access network and service-related data in the Delivery System. Where these definitions are
taken from existing standards, full reference to the required standards is provided. Otherwise a full

ISO/IEC 16500-9:1999(E)
description is integrated in the text of this part. Usage-related information model is defined in ISO/IEC
16500-9.
ISO/IEC 16500-9 (DAVIC 1.3.1a Part 11) specifies the interface requirements and defines the formats for the
collection of usage data used for billing, and other business-related operations such as customer profile
maintenance. It also specifies the protocols for the transfer of Usage Information into and out of the
ISO/IEC 16500 digital audio-visual system. In summary, flows of audio, video and audio-visual works are
monitored at defined usage data collection elements (e.g. servers, elements of the Delivery System, set-top
boxes). Information concerning these flows is then collected, processed and passed to external systems such
as billing or a rights administration society via a standardised usage data transfer interface.
Additional Information
ISO/IEC TR 16501 is an accompanying Technical Report. Further architectural and conformance information
is provided in other non-normative parts of DAVIC 1.3.1a (1999). A summary of these documents is included
here for information.
ISO/IEC TR 16501 (DAVIC 1.3.1a Part 1) provides a detailed listing of the functionalities required by users
and providers of digital audio-visual applications and systems. It introduces the concept of a contour and
defines the IDB (Interactive Digital Broadcast) and EDB (Enhanced Digital Broadcast) functionality
requirements which are used to define the normative contour technology toolsets provided in
ISO/IEC 16500-3.
DAVIC 1.3.1a Parts 3, 4 and 5 are DAVIC technical reports. They provide additional architectural and other
information for the server, the delivery-system, and the Service Consumer systems respectively. Part 3
defines how to load an application, once created, onto a server and gives information and guidance on the
protocols transmitted from the set-top user to the server, and those used to control the set-up and execution of
a selected application. Part 4 provides an overview of Delivery Systems and describes instances of specific
DAVIC networked service architectures. These include physical and wireless networks. Non-networked
delivery (e.g. local storage physical media like discs, tapes and CD-ROMs) are not specified. Part 5 provides
a Service Consumer systems architecture and a description of the DAVIC Set Top reference points defined
elsewhere in the normative parts of the specification.
DAVIC 1.3.1a Part 13 is a DAVIC technical report, which provides guidelines on how to validate the
systems, technology tools and protocols through conformance and / or interoperability testing.
