Evolution for FM Radio Broadcasting
The goal of FMD is to energise and provide the tools to enable the FM broadcast business to transmit successful content delivery to multiple devices, and the FM receiver business the mechanisms to produce new exciting capabilities to receive FMD in a seamless way that today’s listeners demand. All this capability is to be wrapped into a practical business plan method to ensure the success of a FMD deployment.
Broadcasters Leverage Existing Infrastructure
Providing the FM broadcast industry with revolutionary mechanisms that allows a broadcaster to leverage their existing infrastructure investment to be transmit additional digital content, using a method that is fully backward compatible with even the oldest FM radio receiver of a potential listener, is spectrum friendly and importantly, the ability for the broadcaster to make unique configurations of their digital transmissions applicable to their geography, market and listeners, FMD is the way forward. Imagine been able to deploy across 10,000 FM broadcast stations globally within just twelve months with a simple software upgrade on existing equipment…
Listeners Have Choice & Flexibility & Capability
Listeners demand choice and require a technology that evolves with the listeners age group, has flexibility with roaming across multiple delivery transports for continuous hands free listening and the capability to handle the future multimedia. Add to this that the all important listener demographic is changing with new and some would say disruptive technology providing new capabilities to keep the listener attracted to the content. The future of broadcasting must grasp this to capture the audience and FMD is destined to be the transport mechanism to successfully conduct this whilst maintaining broadcast as focal point.
Just like existing FM sub-carriers are free from any royalties, it is to be mandatory that the baseline FMD standard is also royalty free, including any codecs used in the transmission of content. At this early stage, it is proposed to create the FMD standard under the Open Source Initiative legal framework.
Building a royalty free FMD standard will encourage development in both structured, viral and opensource environments with developers primed to use modern DSP & computing technologies already deployed into the public space for practical and successful development.
However the proposed baseline FMD standard is not to preclude manufacturers from patent extensions to the standard. For example, a receiver manufacturer may wish to include enhanced methodology for improved reception above that of the standard baseline FMD standard.
Putting the Pieces Together
FMD will require input from many parties, including
- Suppliers of MPX Encoders, Transmission & Receiver Equipment
- Business Developers
The Ultimate Goal
Quality, reliability and capability is the ultimate goal for FMD. We need to enable a Quality of Service for the listening device, thus allowing the the broadcaster’s content to seamlessly transferred across any reference link transports (eg FM Stereo, FM Mono, iBOC, DAB, Internet streaming, etc) without dropout where ever possible. All this is to be under control broadcaster.
Team Effort – A Call to All
Do you or your company wish to be part of this?

Do you wish to provide input to the next generation of broadcast radio?
You invited to the Forum to have your say, provide input and begin this new evolution in FMD.
Just register and begin this journey with us all into this next evolution of FM audio broadcasting.
FMD modulates data on the wideband FM carrier, where in most cases with professional transmission equipment and audio processing equipment with MPX composite connectivity, a FM broadcaster is highly likely be ready to transmit FMD.
The goal of FMD is for the Transport and Content Streams to be configured per broadcasters needs and support change on demand. Initial deployments of FMD are expected to be modulated above the existing RDS frequency when sharing with an existing analog FM stereo audio signals, with an expectation to fit 1 high quality stereo audio streams within, even more depending upon transmit bit rate, EiRP, geography and listener requirements. Flexibility for the broadcaster is key.
For the audio codec, we look forward to the industry coming forth with high quality low bit rate codecs, such as AAC, OGG or even something new.
The ultimate final goal is to enable a Quality of Service for the listening device, thus allowing the the broadcaster’s content to seamlessly transfer across multiple transports (eg FM Stereo, FM Mono, iBOC, DAB, Internet streaming) without dropout where ever possible. All this under control of the broadcaster.
