What is this BS IEC 62106‑3 - RDS usage and registration of ODA 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 62106‑3 is the third part of the BS IEC 62106 multi-series on RDS. BS IEC 62106‑3 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. BS IEC 62106‑3 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.
Who is BS IEC 62106‑3 - RDS usage and registration of ODA for?
BS IEC 62106‑3 on RDS usage and registration of ODA is useful for:
- Radio stations
- Radio equipment manufactures
- Radio broadcasters
- Product development teams
Why should you use BS IEC 62106‑3 - RDS usage and registration of ODA?
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 62106‑3 discusses ODA usage, ODA Application Identification (AID), ODA group availability signalled in group type 3A for legacy data ODA coding for group type C on data-streams 1, 2, and 3, ODA registration, ODA-AID codes reserved for testing with no registration being required, open data registration. Using BS IEC 62106‑3 guidelines you would be able to address the issue of data capacity, which lets your customers have better radio reception.
What’s changed since the last update?
BS IEC 62106‑3:2018 supersedes IEC 62106:2015, which is withdrawn. BS IEC 62106‑3:2018 includes some technical changes with respect to IEC 62106:2015.
These include:
- 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
