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 case-studies/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.
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 v1.3.1 – RadioDNS Hybrid Radio; Hybrid lookup for radio services Updated 16th May 2019
ECC AND ISO COUNTRY CODES
The use of ISO Country Codes in DNS lookups has been deprecated from v1.1.1 of the Hybrid 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.
Applications
Applications provide specific functionality.
- TS 101 499 v3.1.1 – Slideshow – How to deliver clickable visual content over IP alongside broadcast radio
- TS 102 818 v3.3.1 – 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 1st September 2020
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.
- Proposed changes to TS 102 818 (Service and Programme Information)
- TAG – RTAG01 v1.0.0 Draft 7 (Working Draft)
The Radio Device Metadata Terms of Use has moved here.
HOWTO
We have a collection of HOWTO documents, which are step-by-step guides to implementing RadioDNS Hybrid Radio functionality.
- HOWTO – Create Station Logos Descriptions and Other Metadata in an SI XML file using the RadioDNS SI Tool
- HOWTO – Make SI files accessible to RadioDNS Hybrid Radio devices
- HOWTO – Register your station for RadioDNS Hybrid Radio
- HOWTO – Add SRV Records to your Authoritative FQDN
- HOWTO – Use the GCC Global Country Code Library
- HOWTO – Implementing High Definition Visuals
- HOWTO – Restrict listening by time of day / programme
- HOWTO – Basic Analytics using RadioDNS
Technical Presentations
A collection of presentations from technical conferences explaining how to manage RadioDNS Hybrid Radio application systems.
- 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
Support
If you need technical support, please post your question on the relevant Discussion Board, or email feedback@radiodns.org
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 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
