These documents are here to help developers of RadioDNS Hybrid Radio systems and receiver implementations
On this page you’ll find the current (and prior) versions of our standards, proposals for new standards, HOWTO guides with step-by-step information, and technical presentations.
Current Standards
These are the latest versions of all our published standards. Use these versions when you’re developing anything new. They are free to download and use. We do not charge any licence or patent fees, and we are not aware of any patent claims on our standards.
Core Lookup
You need the core lookup specification to create a DNS lookup to find the FQDN (Fully Qualified Domain Name) for a radio station, so you can make an IP connection.
- TS 103 270 v1.4.1 – RadioDNS Hybrid Radio; Hybrid lookup for radio services Updated 9th May 2022
Applications
Applications provide specific functionality.
- TS 102 818 v3.4.1 – Service and Programme Information – How to describe meta-data about a radio station (including logos) and its individual programmes and schedule, as well as an index of on-demand/podcast material. The version 3.3 XSD Schema for validation of SPI XML documents is here. Updated 9th May 2022
- TS 101 499 v3.2.1 – Slideshow – How to deliver dynamic content (visuals, text and metadata) over IP alongside broadcast radio. Updated 24th August 2023
Proposed Standards
These documents are work in progress of new applications being worked on by Working Teams. They’re unstable, liable to change, and here for information only.
The Radio Device Metadata Terms of Use has moved here.
HOWTO
All our step-by-step HowTo guides have moved here.
Technical Presentations

- Seminar – Code School to Implement an SI.xml File (NAB) – July 2020
- Presentation – How to Generate RadioVIS Content – February 2012
- Presentation – How to Manage ActiveMQ for STOMP/RadioVIS – February 2012

Prior Versions
You shouldn’t use these documents any more, except for historic reference.
- RadioDNS Core Lookup – RDNS01 v1.0.0
- Visual Slideshow (RadioVIS) – RVIS01 v1.1.0
- Service and Programme Information (RadioEPG) – REPG01 v1.1.0
Deprecated – ISO Country Codes in DNS Lookups
The use of ISO Country Codes in DNS lookups was deprecated from v1.1.1 of the core lookup specification. All DNS lookups for FM or DAB are required to provide the ECC code. ECC is an optionally transmitted parameter.
Receiver implementers are strongly recommended to implement the process to determine an ECC code from geo-location information, and a code library is provided to support that.
Deprecated – XSI file format
Standard REPG01 defined an XSI file type. This has been superseded by the SI file definition of TS 102 818. We are not aware of any devices in market which require the XSI file, so recommend that you do not implement it. The SI tool currently supports editing in both XSI and SI formats, but this function will be withdrawn in Spring 2019. The XSL-T transforms to allow conversion between SI and XSI will remain in the RadioDNS GitHub
