What is this BS IEC 62106‑6 - Technical specifications for Open Data Applications in the public domain about?
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification, and program information.
BS IEC 62106‑6 is the sixth part of the BS IEC 62106 multi-series on RDS. BS IEC 62106‑6 contains the technical specifications for Open Data Applications in the public domain. BS IEC 62106‑6 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 are decoded on a receiver. The receiver needs an 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.
Who is BS IEC 62106‑6 - Technical specifications for Open Data Applications in the public domain for?
BS IEC 62106‑6 on VHF/FM for ODA is useful for:
- Radio stations
- Radio equipment manufactures
- Radio broadcasters
- Product development teams
Why should you use BS IEC 62106‑6 - Technical specifications for Open Data Applications in the public domain?
Radio technology is constantly evolving. 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.
BS IEC 62106‑6 discusses ODAs in the public domain, ODAs in the 37-bit ODA application group structure, traffic Message Channel (TMC), other public ODAs, ODAs in the group type C structure for the upper data-streams 1, 2 and 3, coding of RadioText Plus (RT+) tagging information for
Radio Text in group type 2A/B, RT+ tag, RT+ information elements and data model, Receiver data model, RT+ coding for RT, coding of the RT+, clearing of RT+ messages, and broadcasting conventions.
What’s changed since the last update?
BS IEC 62106‑6:2018 supersedes IEC 62106:2015, which is withdrawn. BS IEC 62106‑6:2018 includes a technical change with respect to IEC 62106:2015.
These are:
- 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
