Information technology - Generic digital audio-visual systems - Part 3: Contours: Technology domain

This part of ISO/IEC 16500 on "Contours: Technology Domain" describes the system functions and DAVIC tools relevant to the Contours defined in ISO/IEC TR 165001. A goal of this part of ISO/IEC 16500 is to guide implementers to those parts of ISO/IEC 16500 which are relevant for the implementation of the systems in each Contour and to show the relation between the various tools. Another goal of this specification is to state which specific DAVIC tools have to be implemented to realize interoperable system components. As the underlying trade-off between system component cost and service revenue may vary considerably, e.g., by geographical location and time, this trade-off is deemed to be outside of the scope of DAVIC and hence a more detailed "micro profiling" of the tool set needs to be agreed upon between the various parties involved with the realization of a system. An STB that is fully interoperable with, for example, Enhanced Broadcast Services within a certain geographical area, can be designed by implementing all defined DAVIC tools used by the Enhanced Broadcast Services in that area. In order to assist the above mentioned micro-profiling activity the DAVIC tools relevant to a specific Contour have been structured in the following way. A collection of DAVIC tools (sub/clauses of ISO/IEC 16500) which together realize a complete system function (e.g., the reliable transmission of synchronized multimedia information) are grouped together. The group is identified as "system function". For each of these groups an overall informative description is given and a table listing in detail the included DAVIC tools. For the tools dependencies are indicated if applicable. The functional requirements derived from the User & Market Domain of a contour (see ISO/IEC TR 16501) are fully mapped to the above list of system functions.

Overview

ISO/IEC 16500-3:1999 - "Information technology - Generic digital audio-visual systems - Part 3: Contours: Technology domain" (DAVIC) defines the technology contours and required toolsets for interoperable digital audio‑visual systems. This part of ISO/IEC 16500 guides implementers to the specific DAVIC tools and system functions needed to realize the defined Contours (notably Enhanced Digital Broadcast (EDB) and Interactive Digital Broadcast (IDB)). It is a normative compliance document that maps functional requirements from ISO/IEC TR 16501 to concrete technology building blocks.

Key topics and requirements

• Contours and system functions: Groups of DAVIC tools are organized into “system functions” (e.g., reliable transmission of synchronized multimedia). Each group includes informative descriptions and detailed tool lists.
• DAVIC tools and dependencies: The standard identifies which DAVIC subclauses must be implemented for interoperable components and indicates tool dependencies for micro‑profiling.
• Normative annexes: Annex A (EDB) and Annex B (IDB) provide detailed, mandatory lists of system functions and the tools required to implement them.
• Interoperability focus: Specifies the minimum set of technologies and behaviors to ensure end‑to‑end interoperability across networks, devices and countries.
• Normative references: Cross-references established standards used by DAVIC (examples include MPEG‑2 / ISO/IEC 13818 and ASN.1 / ISO/IEC 8824), ensuring alignment with widely used media and encoding standards.
• Scope limits: Economic trade‑offs (cost vs revenue) and detailed micro‑profiling decisions are explicitly outside DAVIC’s scope and are to be agreed among implementers.

Practical applications

• Designing and implementing interoperable set‑top boxes (STBs) that support EDB or IDB services by implementing the specified DAVIC tools.
• Defining technology profiles for broadcast and interactive service deployments, enabling consistent feature sets across geographic areas.
• Guiding system integrators and network operators in selecting the minimum toolset for compliance and conformance.
• Supporting conformance and interoperability testing, product certification, and procurement specifications for digital audio‑visual delivery systems.

Who should use this standard

• STB manufacturers and firmware developers
• Broadcast service architects and platform vendors
• Network operators and system integrators
• Test labs and certification bodies
• Standards and compliance engineers working on digital audio‑visual interoperability

Related standards / references

• ISO/IEC 16500 family (Parts 1–9) for system models, protocols, information representation, security and management

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 description is
integrated in the text of this part. Usage-related information model is defined in ISO/IEC 16500-9.
© ISO/IEC 1999 - All rights reserved DAVIC 1.3.1a Part 14 (1999)   v

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.

Information technology — Generic digital audio-visual systems — Part 3:
Contours: Technology domain
1. Scope
This part of ISO/IEC 16500 on “Contours: Technology Domain” describes the system functions and DAVIC
tools relevant to the Contours defined in ISO/IEC TR 165001. A goal of this part of ISO/IEC 16500 is to guide
implementers to those parts of ISO/IEC 16500 which are relevant for the implementation of the systems in each
Contour and to show the relation between the various tools. Another goal of this specification is to state which
specific DAVIC tools have to be implemented to realize interoperable system components.
As the underlying trade-off between system component cost and service revenue may vary considerably, e.g., by
geographical location and time, this trade-off is deemed to be outside of the scope of DAVIC and hence a more
detailed “micro profiling” of the tool set needs to be agreed upon between the various parties involved with the
realization of a system. An STB that is fully interoperable with, for example, Enhanced Broadcast Services within
a certain geographical area, can be designed by implementing all defined DAVIC tools used by the Enhanced
Broadcast Services in that area.
In order to assist the above mentioned micro-profiling activity the DAVIC tools relevant to a specific Contour
have been structured in the following way. A collection of DAVIC tools (sub/clauses of ISO/IEC 16500) which
together realize a complete system function (e.g., the reliable transmission of synchronized multimedia
information) are grouped together. The group is identified as “system function”. For each of these groups an
overall informative description is given and a table listing in detail the included DAVIC tools. For the tools
dependencies are indicated if applicable. The functional requirements derived from the User & Market Domain of
a contour (see ISO/IEC TR 16501) are fully mapped to the above list of system functions.

6. Concepts — Contours, Systems and Interoperability
This clause describes the underlining concepts of Contours within this this part of ISO/IEC 16500.
Figure 6-1 illustrates the definition of “Technology Domain” in the concept of “DAVIC Contours”. The detailed
definition of “DAVIC Contours” is provided in ISO/IEC TR 16501.

Figure 6-1 — Contour Definition and Technology Domain
The systems based on DAVIC specifications will be built upon a set of “technical tools” specified in the DAVIC
contour, plus some of additional tools which may or may not specified by DAVIC. These relationships are
illustrated in Figure 6-2.

Figure 6-2 — Concept of a Contour and Systems
The goal of the contour concept is to achieve the maximum interoperability between systems implemented based
on a specific contour definition and, at the same time, between systems built upon different defined contours.
The latter is important for easy migration (or elaboration) of the systems from one contour to another.

Figure 6-3 — Interoperability between Contours
“Interoperability”, “Conformance” and “Compliance” and in the context of technical description of Contours are
defined as:
Interoperability
is the ability between two or more implementations to interact with each other as required by the contour
specification. Interoperability can only be determined between sub-systems which are part of an end-to-end
system that encompasses the entire contour. Sub-systems are separated by DAVIC reference points.
Interoperability can only be tested between sub-systems connected to the same reference point or to different
reference points connected via a transparent link for the protocol peers be tested.

Conformance
means providing system functions, as defined in a particular contour, used by the services in a system for which
conformance is declared. These functions have to be implemented according to the tool definition as described in
the contour’s list of tools. The set of system functions used needs to be agreed upon by the parties involved with
the realization of the system. Conformance can only be declared to a Contour listing those system functions
which are provided in the system.
Compliance
means providing all of the system functions specified in a Contour according to the mapping to DAVIC
technologies specified in the corresponding annex of this part of ISO/IEC 16500. DAVIC systems compliant to a
particular Contour are characterized as follows:
� The system must be built from the set of tools defined in ISO/IEC 16500 and referred in the annex of this
part of ISO/IEC 16500 for the particular Contour
� The system must illustrate DAVIC conformance at reference points defined in ISO/IEC 16500-1 and
referred in the annex of this part of ISO/IEC 16500 for the particular Contour
� The system must perform functional requirements defined in ISO/IEC TR 16501 and referred in the annex
of this part of ISO/IEC 16500 Part 14 for the particular Contour.
Appropriate reference points must be accessible to allow effective interoperability testing throughout the system.

A.2 Overview of system functions
Table A2-1, Table A2-2, Table A2-3, and Table A2-4 list the system functions relevant to the Enhanced
Digital Broadcast Contour. As described above, system functions are a collection of DAVIC clauses
which together realize a complete system function. For each of the system functions it is indicated
which DAVIC Clause implements the function, the Reference Point to which the function applies, the
system location where the function is implemented and other system functions which shall be
implemented if the function is implemented. An acronym is assigned to each function for further
reference. This acronym is used in subclause A.4 of this Annex where detailed lists of DAVIC tools
belonging to each function are given.
Note that these system functions have been defined on the basis of DAVIC 1.2 tools. Revisions of this
technology contour may include new functions when suitable tools are identified according to the
DAVIC Rules for technical procedure.
