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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2. www .iso .org/directives

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received. www .iso .org/patents

assessment, as well as information about ISO's adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

The committee responsible for this document is ISO/TC 204, Intelligent transport systems.

This third edition cancels and replaces the second edition (ISO 14819-1:2013), which has been

technically revised.
This third edition cancels and replaces all previous versions.

ISO 14819 consists of the following parts, under the general title Intelligent transport systems — Traffic

and travel information messages via traffic message coding:

— Part 1: Coding protocol for Radio Data System — Traffic Message Channel (RDS-TMC) using ALERT-C

— Part 2: Event and information codes for Radio Data System — Traffic Message Channel (RDS-TMC)

using ALERT-C

— Part 3: Location referencing for Radio Data System — Traffic Message Channel (RDS-TMC) using ALERT-C

— Part 6 (to become deprecated): Encryption and conditional access for the Radio Data System — Traffic

Message Channel ALERT C coding
Compared to previous releases, this version includes the following additions:

— Additional tuning variants have been added to allow referencing of TMC services using the 64MHz

to 88 MHz band.

— The method of encrypting an RDS-TMC service, previously separately specified in 14819-6, has

been merged into this specification, as Section 8: consequently, some renumbering of sections has

occurred.

— In places the text has been improved for greater clarity. Several typographical and grammatical

errors have been corrected.
