This Technical Specification (CEN/TS) was approved by CEN on 28 September 2004 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

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 18234-3 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.
ISO/TS 18234 consists of the following parts, under the general title Traffic and Travel Information (TTI) — TTI
via Transport Protocol Expert Group (TPEG) data-streams:
⎯ Part 1: Introduction, numbering and versions
⎯ Part 2: Syntax, Semantics and Framing Structure (SSF)
⎯ Part 3: Service and Network Information (SNI) application
⎯ Part 4: Road Traffic Message (RTM) application
⎯ Part 5: Public Transport Information (PTI) application
⎯ Part 6: Location referencing applications

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 a user’s equipment.
This document describes the Service and Network Information Application, which provides a means of
informing end-users about all possible services and their content which are considered relevant by a service
provider to either provide continuity of his services or inform the end-user about other related services. As
stated in the design criteria, TPEG is a bearer independent system. Therefore some rules are established for
the relation of information contents of the same service on different bearers. Also the mechanisms for
following a certain service on one single bearer have to be defined. For the client decoder it is essential to find
an adjacent or similar service if it leaves the current reception area. Nonetheless, basic information describing
the service itself is necessary. For the ease of the user, e.
