FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as
"IEC Publication(s)"). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other
IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62106-5 has been prepared by technical area 1: Terminals for
audio, video and data services and contents, of IEC technical committee 100: Audio, video
and multimedia systems and equipment.
This first edition, together with IEC 62106-1, IEC 62106-2, IEC 62106-3, IEC 62106-4 and
IEC 62106-6, cancels and replaces IEC 62106:2015, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC 62106:2015:
• provision has been made to carry RDS on multiple data-streams (RDS2);
• a logo for RDS2 has been added,
• new are receiver profiles, conformity requirements, certification and compliance test.

INTRODUCTION
Since the mid-1980s a fascinating development has taken place. Most of the multimedia
applications and standards have been created or redefined significantly. Hardware has
become extremely powerful with dedicated software and middleware. In the mid-1980s
Internet as well as its protocols did not exist. Navigation systems became affordable in the
late 1990s, and a full range of attractive smartphones now exist. The computing power of all
these new products is comparable with that of the mainframe installations in that era.
Listener expectations have grown faster than the technology. Visual experience is now very
important, like the Internet look and feel. Scrolling text or delivering just audio is nowadays
perceived as insufficient for FM radio, specifically for smartphone users. New types of radio
receivers with added value features are therefore required. RDS has so far proven to be very
successful.
FM radio with RDS is an analogue-digital hybrid system, which is still a valid data
transmission technology and only the applications need adaptation. Now the time has come to
solve the only disadvantage, the lack of sufficient data capacity. With RDS2, the need to
increase the data capacity can be fulfilled.
RDS was introduced in the early 1980s. During the introductory phase in Europe, the car
industry became very involved and that was the start of an extremely successful roll-out.
Shortly afterwards RDS (RBDS) was launched in the USA.
The RDS Forum has investigated a solution to the issue of limited data capacity. For RDS2,
both sidebands around the RDS 57 kHz subcarrier can be repeated a few times, up to three,
centred on additional subcarriers higher up in the FM multiplex still remaining compatible with
the ITU Recommendations.
The core elements of RDS2 are the additional subcarriers which will enable a significant
increase of RDS data capacity to be achieved and then only new additional data applications
will have to be created, using the RDS-ODA feature, which has been part of the RDS standard
IEC 62106 for many years.
In order to update IEC 62106:2015 to the specifications of RDS2, IEC 62106 has been
restructured as follows:
Part 1: Modulation characteristics and baseband coding
Part 2: RDS message format, coding and definition of RDS features
Part 3: Usage and registration of Open Data Applications ODAs
Part 4: Registered code tables
Part 5: Marking of RDS and RDS2 devices
Part 6: Compilation of technical specifications for Open Data Applications in the public domain
The following future parts are planned:
Part 7: RBDS
Part 8: Universal Encoder Communication Protocol UECP
The original specifications of the RDS system have been maintained and the extra
functionalities of RDS2 have been added.
