EN 62106:2001

Specification of the radio data system (RDS) for VHF/FM sound broadcasting in the frequency range from 87,5 to 108,0 MHz

The Radio Data System (RDS) applies to VHF/FM sound broadcasts, which may carry stereophonic or monophonic programmes. RDS improves functionality of receivers by implementing features such as Programme Identification, Programme Service and automatic tuning.

INTERNATIONAL ELECTROTECHNICAL COMMISSION
SPECIFICATION OF THE RADIO DATA SYSTEM (RDS) FOR VHF/FM SOUND
BROADCASTING IN THE FREQUENCY RANGE FROM 87,5 TO 108,0 MHZ
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical
committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization
in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation
is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.
International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates
closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the
relevant subjects since each technical committee has representation from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical
specifications, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the
maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or
regional standard shall be clearly indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity
with one of its standards.
This International Standard IEC 62106 has been prepared by the IEC Subcommittee 100A: Multimedia end-user equipment,
of the Technical Committee 100: Audio, video and multimedia systems and equipment.
This standard is based on the European CENELEC Standard EN 50067:1998 prepared by the RDS Forum, using an earlier
specification [8] that was originally developed within the European Broadcasting Union. It was submitted to the National
Committees for voting under the Fast Track Procedure as the following documents:
FDIS Report on voting
100A/134A/FDIS 100A/139/RVD
Full information on the voting for the approval of this standard can be found in the report indicated in the above table.
Attention is drawn to the fact that there may be Intellectual Property Rights (IPR) in relation to certain provisions of this
standard. IPR holders should notify the IEC of their claims.
This publication has not been drafted in complete accordance with the ISO/IEC Directives, Part 3.
Annexes B, C, G, H, K, L and Q are for information only.
Annexes A, D, E, F, J, M, N, and P form an integral part of this standard.
