Intelligent transport systems — Traffic and travel information via transport protocol experts group, generation 1 (TPEG1) binary data format — Part 10: Conditional access information (TPEG1-CAI)
ISO 18234-10:2013 contains the definition of the TPEG Conditional Access Information (CAI) application. It enables dedicated conditional access data, such as management messages (e.g. Control Words and Entitlement Control Messages) to be delivered to recipient client devices. This TPEG application is designed for a service provider to: establish setup, prolongation or revocation of services to a specific client device, using a limited capacity unidirectional broadcast channel and without recourse to service-client handshaking. This TPEG application defines: the logical channel, for the transmission of the additional CA information (CAI); how the CAI is linked and synchronized to the scrambled content.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 18234-10 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 278, Road transport and traffic telematics, in collaboration with ISO Technical Committee
ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
ISO/TS 18234 consists of the following parts, under the general title Intelligent transport systems — Traffic
and travel information via transport protocol experts group, generation 1 (TPEG1) binary data format:
Part 1: Introduction, numbering and versions (TPEG1-INV)
Part 2: Syntax, semantics and framing structure (TPEG1-SSF)
Part 3: Service and network information(TPEG1-SNI)
Part 4: Road Traffic Message application (TPEG1-RTM)
Part 5: Public Transport Information (PTI) application
Part 6: Location referencing applications

Part 8: Congestion and travel-time application (TPEG1-CTT)
Part 9: Traffic event compact (TPEG1-TEC)
Part 10: Conditional access information (TPEG1-CAI)
Part 11: Location Referencing Container (TPEG1-LRC)
Introduction
TPEG technology uses a byte-oriented data stream format, which may be carried on almost any digital bearer
with an appropriate adaptation layer. TPEG-messages are delivered from service providers to end-users and
used to transfer information from the database of a service provider to an end-user’s equipment.
The brief history of TPEG technology development dates back to the European Broadcasting Union (EBU)
Broadcast Management Committee establishing the B/TPEG project group in autumn 1997 with the mandate
to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the
multimedia environment. TPEG technology, its applications and service features are designed to enable
travel-related messages to be coded, decoded, filtered and understood by humans (visually and/or audibly in
the user’s language) and by agent systems.
One year later in December 1998, the B/TPEG group produced its first EBU specifications. Two Technical
Specifications were released. ISO/TS 18234-2, described the Syntax, Semantics and Framing Structure,
which is used for all TPEG applications. ISO/TS 18234-4 (TPEG-RTM) described the first application, for
Road Traffic Messages.
Subsequently, CEN/TC 278/WG 4, in conjunction with ISO/TC 204, established a project group comprising the
members of B/TPEG and they have continued the work concurrently since March 1999. Since then two further
parts were developed to make the initial complete set of four parts, enabling the implementation of a
consistent service. ISO/TS 18234-3 (TPEG-SNI) describes the Service and Network Information Application,
which should be used by all service implementations to ensure appropriate referencing from one service
source to another. ISO/TS 18234-1 (TPEG-INV), completes the series, by describing the other parts and their
relationship; it also contains the application IDs used within the other parts. Additionally ISO/TS 18234-5 the
Public Transport Information Application (TPEG-PTI) and ISO/TS 18234-6 (TPEG-LRC), were developed.
TPEG applications are developed using UML modelling and a software tool is used to automatically select
content which then populates this TS. Diagrammatic extracts from the model are used to show the capability
of the binary coding in place of lengthy text descriptions; the diagrams do not necessarily include all relevant
content possible.
This Technical Specification describes the binary data format of the on-air interface of the Conditional Access
Information application, (TPEG-CAI) with the technical version number TPEG-CAI_1.0/001.
CAI application
The basic concept behind the CAI application is to transport CAI in separate TPEG service components of a
dedicated application type and to define an SNI table that contains the link between scrambled content and
related CAI.

specified, which are signalled by the TPEG service Encryption Indicator to allow client devices to operate
correctly.
