RadioDNS Hybrid radio seamlessly combines the strengths of Broadcast radio and the Internet.

Broadcast signals (FM, HD, DAB, DAB+) carry audio (and some data), but a device with an Internet connection (WiFi, 3G, 4G, LTE) can seamlessly connect to the radio station for multimedia and interactivity. It allows you to deliver an app-like experience of broadcast radio to the user

Why RadioDNS Hybrid Radio?

Broadcast radio has many advantages.

  • Coverage is broad and consistent and managed by the radio stations
  • Coverage limitations are already understood by listeners
  • Broadcast spectrum is protected and regulated to ensure good quality of coverage
  • Power consumption is much lower than streaming audio over mobile internet
  • Broadcast receiver technology is mature, stable and low-cost
  • But broadcast is only one-direction, without targeting, interactivity or meta-data

Broadcast is well suited for the mass-market ubiquitousness of radio.

Mobile Internet (3G, 4G, WiF) is transforming connectivity

  • Mobile networks are not designed for the consistent data-rates required for live streaming
  • Users are fearful of exceeding their data allowances and streaming flattens batteries quickly
  • Broadcasters can’t influence the extent of coverage, which leaves gaps in important places (main roads)
  • Streaming applications give a good navigation/discovery experience, but are proprietary
  • But it’s the only way to provide targeted content and interactivity.

RadioDNS Hybrid Radio combines the best of both approaches, preserving all the value of broadcast radio and adding new functionality delivered in parallel over an Internet connection.

Devices without an Internet connection continue to receive radio exactly as they do now. Stations that are providing RadioDNS Hybrid Radio applications create a more contemporary and interactive experience of radio which is much more like an app, encouraging discovery and long times spent listening to ‘free’ music and entertainment.
