RadioDNS

What RadioDNS does

RadioDNS is a UK-registered not-for-profit standards organization founded in 2008 and incorporated as RadioDNS Limited in December 2013. The company develops and maintains open, royalty-free technical standards for Hybrid Radio, which link broadcast radio signals (FM, DAB, DAB+, HD Radio) with internet services via DNS lookup. Its core technology stack is built around ETSI-published specifications (TS 103 270 for Hybrid Lookup, TS 102 818 for Service and Programme Information, TS 101 499 for Visual Slideshow) plus extended features for Service Following, Targeted Content, Analytics, and Interaction (Tagging). RadioDNS operates the DNS root servers for the radiodns.org domain and has maintained zero end-user affecting DNS downtime since 2014.

The organization's customer base comprises broadcasters (BBC, NPR, EBU and commercial radio groups), automotive manufacturers (Audi, VW, Porsche, BMW, CARIAD), consumer electronics makers (Samsung, Revo, Philips, PURE), and a network of implementation service providers (Pluxbox, Radioplayer, Aiir, All In Media, Folder Media, togglebit, Omny Studio, Vizion'R). All technical standards and DNS lookup services are free to use with no patent or license fees. The company operates as a member-driven organization funded entirely through annual membership fees (GBP 4,500 per year in 2024), which provide voting rights, technical support, advanced testing tools, and certification. A small supplementary revenue stream from running DNS services for digital TV represents less than 5% of annual expenditure.

RadioDNS is governed by a Steering Board elected every two years from its membership, with day-to-day operations run by a two-person Project Office (Project Director Nick Piggott and Project Coordinator Rosie Kendrick). The organization operates as a virtual entity with staff located across different cities and countries, conducting business primarily through email, calls, and video conferencing. Its registered office is in Bristol, United Kingdom. The organization reaches its audience through industry events (NAB Show, Radiodays Europe, BroadcastAsia, CES), joint Automotive Workshops with WorldDAB, comprehensive technical documentation, and open-source code repositories on GitHub.

Products and services

• RadioDNS Hybrid Radio Standards Open, royalty-free technology standards that combine broadcast radio (FM, DAB, DAB+, HD Radio) with internet connectivity to deliver enhanced hybrid radio experiences in connected vehicles and devices, comprising Lookup (TS 103 270), Service and Programme Information (TS 102 818), and Visual Slideshow (TS 101 499) along with optional features such as Service Following, Targeted Content, Analytics, and Interaction.
• RadioDNS Lookup Authoritative DNS-based lookup service (ETSI TS 103 270) that creates a link between broadcast radio signals and internet domains, enabling radio receivers and connected vehicles to discover additional services and content associated with a radio station.
• Service and Programme Information (SPI) ETSI TS 102 818 XML standard for describing metadata about radio stations, including station logos, names, descriptions, programme schedules, and on-demand/podcast content, enabling accurate station information to be presented on radios and in connected vehicles.
• Visual Slideshow / Visuals and Dynamic Metadata ETSI TS 101 499 standard for delivering dynamic visual content (artist images, news, weather, traffic cams, advertising) over IP alongside broadcast radio, synchronized with the audio stream, rendered on listeners' screens.
• Service Following Capability that automatically switches between broadcast radio and IP streaming when broadcast signal quality degrades, keeping listeners connected to their preferred station regardless of physical location or coverage.
• Station Registration (DNS Registration Service) Managed DNS registration service that creates the link between broadcast signals and internet presence for individual radio stations, enabling all RadioDNS Hybrid Radio activities (lookup, visuals, service following, analytics) for registered stations.
• Software Libraries Open-source libraries and reference code samples available on GitHub in multiple programming languages (Node.js, Perl, PHP, Python, C, Ruby, Java) that implement RadioDNS Lookup and related standards for developers building hybrid radio applications.
• Interaction (Tag) Feature enabling listeners to bookmark/tag moments of interest from broadcast radio with a button press, then revisit that content later on phone, tablet, or desktop devices linked to the same station and account.
• Analytics Standard Standard allowing radio receivers to report broadcast radio listening activity to stations, providing insight comparable to streaming logs so broadcasters can analyse usage of their broadcast services in connected vehicles and devices.
• Targeted Content Capability to deliver targeted content to individual listeners based on location, preferences, or other factors, merging live broadcast audio with IP-delivered targeted content such as local traffic reports, weather maps, and targeted advertising.
• Simple Testing Tool Browser-based tool available for anyone (including non-members) to carry out basic checks on RadioDNS configuration, including validation of FM and DAB broadcast station setups.
• SI Builder Browser-based tool for constructing Service Information (SI) XML files, the foundational building block of RadioDNS hybrid radio services, used by broadcasters and integrators to generate standards-compliant station metadata.
• Testing Platform More extensive suite of testing tools available exclusively to RadioDNS members, providing advanced testing and debugging of hybrid radio implementations beyond the public Simple Testing Tool.
• Project Logo Baseline minimum implementation of RadioDNS Hybrid Radio, defining basic station metadata (station logos, names, descriptions, streaming URLs) that any radio station can implement to enhance how their station is displayed to listeners.

Emerging players

• DTS AutoStage: Connected-car hybrid radio platform from Xperi/DTS that combines broadcast radio with IP streaming and metadata in vehicles. Directly competes with RadioDNS Hybrid Radio for OEM infotainment integrations.
• Pluxbox: RadioDNS implementation partner offering station visualization, SI file management, and RadioVIS services to broadcasters globally. Comparable as a hybrid-radio tooling and services provider within the RadioDNS ecosystem.

Direct peers

• TuneIn: Major internet radio streaming aggregator with deep automotive integration. Comparable as an alternative path to in-vehicle radio listening, though streaming-only rather than hybrid broadcast+IP.

Others

• Gracenote (Nielsen): Provider of music and radio metadata to automotive and broadcast clients. Comparable as a metadata infrastructure vendor serving the same broadcaster and OEM customers RadioDNS targets.
