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further three years, revised to become an International Standard, or withdrawn.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International Standard or be withdrawn.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 18234-1 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

Introduction
TPEG technology uses a byte-oriented 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 are
used to transfer application data from the database of a service provider to an end-user’s equipment.
TPEG has initially been planned and designed to meet a particular brief, from the EBU’s Broadcast
Management Committee. Namely: “to develop a new protocol for Traffic and Travel Information, for use in the
multimedia broadcasting environment to develop applications, service and transport features which will enable
travel-related messages to be coded, decoded, filtered and understood both by humans (visually and/or
audibly) and by agent systems”. This brief is also endorsed by the EBU TTI Broadcast Strategy Team, which
recognizes the vital importance of a bearer independent TTI protocol for broadcast applications.
The following principles have been assumed in the development of the TPEG protocol, structure and
semantics:
⎯ TPEG is unidirectional
⎯ TPEG is byte oriented, where a byte is represented by eight bits
⎯ TPEG provides a protocol structure, which employs asynchronous framing
⎯ TPEG includes a CRC error detection capability applicable on a variety of different levels
⎯ TPEG assumes the use of a transparent data channel
⎯ TPEG assumes that underlying systems will have an appropriate level of reliability
⎯ TPEG assumes that underlying systems may employ error correction
⎯ TPEG has a hierarchical data frame structure
⎯ TPEG is used to transport information from database to database
⎯ TPEG provides service provider name, service name and network information
⎯ TPEG permits the use of encryption mechanisms, if required by an application
TPEG applications contain all the information required by a client TPEG decoder to present all the information
intended for the end-user when it was originated by the service provider.
The protocol is structured in a layered manner and employs a general purpose framing system which is
adaptable and extensible, and which carries frames of variable length. This has been designed with the
capability of explicit frame length identification at nearly all levels, giving greater flexibility and integrity, and
permitting the modification of the protocol and the addition of new features without disturbing the operation of
earlier receiver/decoder models.
TPEG technology has been designed to be usable for a wide range of applications that require the efficient
transmission of point to multi-point data over potentially unreliable broadcast channels. It is also suitable for
point-to-point and multicast applications and may easily be encapsulated in Internet Protocol.
The Broadcast Management Committee of the European Broadcast Union (EBU) established 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. The TPEG technology, its
ISO/TS 18234-1:2006(E)
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 public specifications. Two documents
were released. Part 2 (TPEG-SSF, CEN ISO/TS 18234-2) described the Syntax, Semantics and Framing
structure, which will be used for all TPEG applications. Part 4 (TPEG-RTM, CEN ISO/TS 18234-4) described
the first application, for Road Traffic Messages.
CEN/TC 278/WG 4, in conjunction with ISO/TC 204/WG 10, 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 have been developed to make the initial complete set of four parts, enabling the implementation of a
consistent service. Part 3 (TPEG-SNI, CEN ISO/TS 18234-3)) describes the Service and Network Information
Application, which is likely to be used by all service imp
