IEC 62106-1:2018 defines the basic layer of the Radio Data System (RDS) intended for application to VHF/FM sound broadcasts in the range 64,0 MHz to 108,0 MHz, which can carry either stereophonic (pilot-tone system) or monophonic programmes (as stated in ITU‑R Recommendation BS.450-3 and ITU-R Recommendation BS.643-3). IEC 62106-1:2018 together with IEC 62106-2, IEC 62106-3, IEC 62106-4, IEC 62106-5 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).

Abstract

Overview

IEC 62106-1:2018 specifies the basic layer of the Radio Data System (RDS) for VHF/FM sound broadcasting in the 64.0 MHz to 108.0 MHz band. This Part 1 standard focuses on modulation characteristics and baseband coding used to carry RDS data over FM broadcasts (stereo or mono as per ITU‑R Recommendation BS.450-3 and BS.643-3). The 2018 edition introduces support for carrying RDS on multiple data‑streams (RDS2) and forms the foundational technical specification for RDS transmission and receiver design.

Key topics and technical requirements

The standard defines the core technical building blocks of RDS and RDS2, including:

Subcarrier generation and precise data‑stream subcarrier frequencies for the FM multiplex (including the traditional 57 kHz RDS subcarrier and additional RDS2 subcarriers).
Subcarrier phase and level requirements to ensure compatibility between transmitters and receivers.
Data‑stream modulation requirements, including clock frequency, data rate, and differential coding on all streams.
Baseband coding structure and error protection mechanisms (including a modified shortened cyclic code described in informative annexes).
Data‑channel spectrum shaping, symbol timing and symbol phase shifts across multiple data‑streams to minimize interference with audio services.
Synchronization of blocks and groups across all streams, with defined offset words for group/block sync and implementation guidance.
Normative and informative annexes that cover encoder/decoder theory, shift‑register implementations, and synchronization algorithms.

Practical applications and who uses this standard

IEC 62106-1 is essential for stakeholders involved in FM broadcast data services and device interoperability:

Broadcasters and network operators implementing RDS/RDS2 services to deliver program information, traffic messages, and additional data services.
Transmitter and encoder manufacturers designing compliant RDS modulators and FM multiplexers.
Receiver and automotive electronics vendors ensuring accurate demodulation, decoding and presentation of RDS and RDS2 data on infotainment systems and consumer radios.
Regulators and standards bodies defining national broadcast profiles and frequency planning.
Software developers and ODA (Open Data Application) creators who rely on a stable baseband and message layer for delivering apps and metadata over FM.

ITU‑R Recommendation BS.450‑3 and BS.643‑3: relevant stereophonic and monophonic FM broadcasting references.
RDS Forum specifications for RDS2 extension and application-level features.

Keywords: IEC 62106-1, RDS, RDS2, Radio Data System, VHF/FM, 57 kHz, modulation characteristics, baseband coding, FM multiplex, subcarrier, FM broadcasting.
