RadioDNS provides a way to link broadcast radio with internet services by translating broadcast signal information like frequency and program identification into hostname and IP addresses. It defines several services like RadioVIS, which delivers slideshows to enhance broadcast audio, RadioEPG for electronic program guides, and RadioTAG for user tagging of broadcast content. While RadioDNS has benefits, issues around governance, device support, and service servers need to be addressed for broader adoption.

Introduction to
RadioDNS
Pascal Charest

2. How to listen to radio?

3. What will win the fight?
Internet or Broadcast

4. Why not a win-win situation?
Internet or Broadcast
and

5. RadioDNS
RadioDNS provides the missing link between
broadcast and internet networks.
Uses the broadcast Uses Internet for
infrastructure for additional services
audio delivery

6. What is DNS?
Domain Name System is an internet standard to
translate hostname into IP addresses.

7. What is RadioDNS?
RadioDNS is an hybrid standard that defines a
procedure to translate broadcast signal information
into hostname / IP addresses.

8. How does it work?
Extended country code CE1
Program identification C586
FM frequency 95.8

9. RadioDNS features
Patent free
Not for profit organization
Uses existing infrastructure
Based on existing Internet protocol
Defined for AM / FM / HD Radio / DAB / DRM / Internet
Provides a way to measure audience

13. RadioVIS use cases
"What's playing now?"
"Who's speaking?"
"Is there additional information?"
"What the traffic looks like?"
"Do you have a link with the ad? "
"Yeah, my radio is really hot!"

15. RadioVIS features
Send link of JPEG or PNG images
Send text
Send image and/or text links that user can click on
Based on STOMP protocol (push)
Based on COMET protocol (HTTP push)

16. RadioEPG
RadioEPG provides electronic program guide
on both current and future shows.
timing
contact details
synopsis
station logo
...

17. RadioEPG use cases
"What's playing now?"
"What's playing tomorrow?"
"I want to contact the presenter."
"Please, remind me when this program will play again."

18. RadioEPG features
Defined for AM / FM / DAB / DRM / HD Radio / IP
Common multi-protocol definition
Uses HTTP
Based on ETSI TS 102 818 XML; DAB EPG
Can be used for station logo

19. RadioTAG
RadioTAG provides a tagging framework to capture
user interest in what they are hearing on the radio.
A tag is a collection of meta-data that uniquely
references a point in time to a specific audio service
on a specific device.

20. RadioTAG use cases
"I want to vote for this song."
"I want to subscribe to the podcast for this show."
"I love this song! I want to buy it."
"I want to find out more about this news."
"This ad seems interesting."

21. RadioTAG features
Defined for AM / FM / DAB / DRM / HD Radio / IP
Tag database is on broadcaster server
User authentication
User can add comments
Support multi-devices user
Support offline tagging

22. So, now, where to start?
Configure broadcast signalling (RDS, AMSS, ...)
Ask radiodns.org to add a record in the database
Setup a web server
Setup one of the RadioDNS service:
RadioVIS
RadioTAG
RadioEPG
Et voilà!

23. Issues
Governance
Veracity of information
Do we want to create a RadioDNS Canadian domain
administration?
Devices
We need more devices
FM chips must be enabled in cell phones
The more RadioDNS is used,
the more cellular data is used
RadioDNS service servers
We need more solutions

24. Thank you!
