MT 62106 - TC 100/TA 1/MT 62106

IEC 62106-6:2023 contains the technical specifications for Open Data Applications in the public domain. This document is maintained by the RDS Forum Office. The RDS Forum Office applies an easy procedure for registering new Open Data Applications, to ensure that they can be used without the need to change the RDS standard. The ODA feature permits defining new applications that can be decoded on a receiver. The receiver needs to the adequate software handler for the specific AID, which identifies the application. Receivers that have not implemented the software handler needed for decoding are not affected by ODA data received for any of the applications already defined and specified. The procedure for registering a new ODA is described in IEC 62106-3.
IEC 62106-6:2023 cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Annex E: coding of station logo;
b) Annex F: coding of slideshow;
c) Annex G: coding of internet connection;
d) Annex H: ODA tool – RDS data stream NFM.

IEC 62106-2:2018 defines the coding and definition of features for the Radio Data System (RDS).
IEC 62106-2:2018 together with IEC 62106-1, 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).
• Data in the additional data-streams is using a newly defined group type C data structure.
• AF coding below 87,6 MHz (down to 64,1 MHz) using ODA-AID 0x6365 (see IEC 62106-6).
• Long PS (UTF-8) support has been added using group type 15A.
• Coding for the following applications is no longer detailed in the RDS standard as these can use in future the ODA concept: EWS, TDC, IH and RP.
• Obsolete and no longer part of the RDS standard are: MS (Group 0A, 0B and 15B) certain DI codes (mono/stereo, artificial head, compression), Language code, and PIN (Group 1A).

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).

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).

IEC 62106-3:2018 defines the Open Data Application (ODA) feature of the Radio Data System (RDS). The ODA feature in essence allows raw data to be transmitted via a transparent data channel from a service provider to a suitably equipped receiver without there being any prior knowledge of the data content by the IEC 62106 standard. This document defines the method of packaging the data within the RDS group structure and the identification of the data (using the Application Identification, AID) such that it can be addressed by an appropriate decoder on the receiver.

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).
• For Open Data Applications, in addition to the already existing 37-bit and 21-bit data group structures a new 56-bit or 7-byte data group structure has been added.
• New are AF coding below 87,6 MHz (down to 64,1 MHz) using ODA-AID. RT+ can now be used with RT and eRT, 0x6365, see IEC 62106-6.

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);
• New are AF coding below 87,5 MHz (down to 64,0 MHz) using ODA-AID 0x6365;
• RT+ can now be used simultaneously for RT and eRT, each having its own RT+ ODA;
• Data-streams 1, 2 and 3 are exclusively UTF-8 coded. For backwards compatibility, UCS-2 encoded eRT on data-stream 0 is retained.

IEC 62106-4:2018 provides a number of tables for use in the implementation of the RDS system. This document specifies the procedure for registering a new value in an existing table or the registration of a new table.

IEC 62106:2015(E) describes the Radio Data System, RDS, intended for application to VHF/FM sound broadcasts in the range 87,5 MHz to 108,0 MHz which may 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). The main objectives of RDS are to enable improved functionality for FM receivers and to make them more user-friendly by using features such as Programme Identification, Programme Service name display and, where applicable, automatic tuning for portable and car radios, in particular. The relevant basic tuning and switching information therefore has to be implemented by the type 0 group (see 6.1.5.1), and it is not optional unlike many of the other possible features in RDS. This third edition cancels and replaces the second edition, published in 2009 and constitutes a technical revision. It includes the following changes:
- for the RDS feature EON and the use of group types 14A and 14B some additional explanations were added;
- in Annex E, containing the character code tables to be used in RDS, the explanation for Table E.1 and Table E.2 was extended;
- several small typing errors were corrected;
- to Enhanced RadioText in Annex Q an additional explanation was added.
