ABSTRACT

The principle of hybrid radio is to bridge broadcast and Internet protocol (IP) technologies to leverage the strengths of each individual technology and create a radio experience that is better than could be delivered by using either technology in isolation. Fundamental to the hybrid radio process is the ability to discover and identify radio stations in both the broadcast and IP domains. Having identified a radio service and located its presence on the Internet, it is possible to open an IP connection to the specified host and start exchanging data over IP in parallel to receiving audio over broadcast. Domain name system (DNS) queries require a text domain name as an input, so one approach might be to format the numeric service identifier into a text string. RadioDNS defines applications as open standards, building on the framework of FQDN discovery. As DNS is critical to the functionality of the Internet, it is deployed on a massive scale.
