DRM IN THE FM BAND – SUMMARY OF LIVE COMPLEXES AND TRIALS

 

Here is a compendium of several of the live DRM complexes operating in the FM band today world over and a summary of the most important DRM live transmission trials in the FM band. The results are a testimony of the performance of the DRM standard specifically in the FM. Several countries across the globe have embraced DRM — owing to its performance, power and spectrum efficiency, advanced features, openness (i.e., not depending on or controlled by a single company) and flexibility — as the choice of digital radio technology for their nationwide FM digitization.

DRM is the high-quality and feature-enhanced digital replacement for the former analogue radio broadcasting standards AM and FM; as such it can be operated with the same channeling and spectrum allocations as currently employed. DRM has received the necessary recommendations from the ITU, hence provides the international regulatory support for transmissions.

Is the Car Dashboard Radio’s Next Battlefield?


This often-rehearsed question resurfaces periodically, as radio is facing an uphill struggle against the digital giants ready to grab the dashboard. Hybrid radio is presented as a survival solution on the move, as cars remain a key driver of audio listening.

The term, meaning many things to many people, is very fashionable just now, a bit like “digital,” “convergence” and the “multimedia” mantras of some years back.

Hybrid radio is a mixture of analog radio and digital broadcast sources, like streaming, or a mash between digital radio (mainly of the local variety) and IP-served radio services.

The current orthodoxy goes that, unless good old-fashioned radio or audio also gets all the “bells and whistles” offered by known digital companies and mimics the commercial streaming services provided by the Googles of this world, radio is doomed and will be eliminated from the automotive infotainment landscape.

In the U.S. car listening remains king and accounts for more than 50% of all radio listening. According to the recently unveiled annual 2021 Techsurvey Jacobs Media and Veritone, 58% of the 40,000 U.S. respondents listen to AM/FM radio in the car, 18% to satellite radio while personal music rates some 3%. Smartphones only come in second, after cars.

But more interesting are the ranked reasons for radio’s enduring attraction: easy to listen to, familiar hosts, available for free (i.e. no money), while almost half the listeners agreed that being local is radio’s primary advantage.

Hybrid radio definitely addresses the challenge of “easy to listen to”: press a button or voice-activate your car radio and you are in business. If you leave the coverage area, an IP stream will ensure you can continue to listen to your favorite station or presenter, provided the station stream can be accessed and coordinated with the over-the-air broadcast service.

Hybrid can also paper-over the transmission gaps if your car is fitted with an analog or digital local coverage standard which is sometimes unavailable in the targeted coverage area.

And there are other positive considerations, too. Linking terrestrial broadcasting with IP ensures continuity and enhanced service, personalized and visually rich. This is all enabled by the metadata (song title, branding labels, ads, etc.) that accompany the audio on the mobile broadband connection. Above all, hybrid offers the attractive possibility of a back channel. If the hybrid receiver had, or will have in the future, an extra button for notifications: information, ads, tickets etc., these could be sent directly to your phone or email.

The two-way connectivity is the one thing radio has not been able to offer easily until now. The other is offering reliable data about who is listening to what and for how long. This is less of interest to listeners and more to advertisers and broadcasters. It is also the most valuable and remunerative information hybrid radio could provide.

The proponents of hybrid radio stress that all these attributes, plus the podcasting possibility, are essential for radio’s survival and relevance on the new and flashy dashboards securing its place in the unequal battle with the apps, satellite and Big Tech services.

There are though some big caveats and questions on hybrid radio:

Are stations prepared to foot the bill for the streaming fees linked to the smooth transitioning from terrestrial to IP, not to mention the possible copyright fees incurred while the streaming runs in the background ready to pounce only when terrestrial fails?

Are broadcasters ready to share the streaming URLs and metadata and to make them available to open platforms or commercial entities, be they big patent companies or even car manufacturers?

Is the provision of podcasting essential, considering that in the latest Techsurvey, 6 out of 10 U.S. radio listeners are not bothered by this hot product still not flying after 15 years, not to mention that podcasting does not enhance radio listening but possibly diminishes the radio listening time.

If hybrid radio is the way forward, is this a U.S. and developed world project and commercial venture? According to the information released on the United Nations World Telecommunication and Information Society Day (May 17) 3.7 billion people, almost half the world population, remain unconnected to the internet.

From my own DRM perspective, the simpler question is: why hook up with IP, using extra effort and costs, analog and digital radio, when at least one digital radio standard, DRM, fulfills and satisfies already many of the aspirations of hybrid? DRM already includes SPI and what RadioDNS offers. It can connect broadcast and online, benefits from Journaline to ensure rich services, interactivity and personalized content.

A DRM receiver, in car, on a cell or in the kitchen can carry useful information: logos, maps, pictures, weather, traffic, disaster alerts and education material, addresses and ads.

DRM broadcasters can transmit on any analog frequency (AM or FM) up to three audio channels and one data channel, saving both energy, spectrum and money. One or two , or all three audio channels can be flexibly reassigned to data, so that less audio and more data is presented to users by easily programming the “four digital lanes” of DRM on one 96 kHz (FM) frequency or on an existing AM frequency. RSS feeds can be presented on DRM receivers without the need to publish and give somebody else your streaming URL and metadata information.

Does this mean that the big hybrid radio push will suddenly stop? Of course not, radio needs modern digital clothes, future proofing but also a reality check. Why reinvent the wheel when digital radio, DRM, has everything to benefit listeners and broadcasters?

If a camel is a horse designed by a committee, then hybrid is still a cute camel, not a horse yet.

DRM, STRONGER THAN EVER, LOOKS WITH CONFIDENCE TO 2021 – E-BOOK DOWNLOAD OF ACTIVITIES


In its 100th anniversary year the DRM Consortium salutes radio as the mass digital communication platform for our challenging times. To celebrate the unique and relevant place of radio in people’s lives and the progress made by Digital Radio Mondiale in this unprecedented year, we have created our first ever DRM e-book. Its aim is to give you a succinct overview of the best DRM events, activities and successes in 2020, while offering you a varied and wide digest of information, opinions and updates on DRM and digital radio.

In 2020 the value of the only global, open, all band digital audio broadcasting system, DRM, was conveyed to more people, further afield, than ever before. Old and new stakeholders and enthusiasts were the audience in the 2020 virtual conference rooms where a “show and tell” approach demonstrated DRM’s services and advantages in both AM and FM bands.

We introduced new technical development of the extra-efficient use of DRM FM and devoted a lot of attention to DRM’s capabilities to deliver multimedia and, therefore, textual information needed not only Emergency Warning Functionality (EWF) but also to facilitate distance learning. This is an area we aim to develop in 2021.

Manufacturers from China, India, Germany, South Korea, and U.K showcased dozens of receivers for AM (medium wave) but also for digital FM and in 2021. As manufacturers will receive increased orders, we expect them to bring larger volumes of affordable receivers to the market, as more countries adopt DRM.

Ruxandra Obreja, DRM Chairman, stated that “the new DRM e-book gives a complete, up-to-the minute valuable information on DRM. The DRM e-book demonstrates that this all band-standard has registered significant progress in 2020 and is poised for even bigger successes in 2021, when millions of new and old listeners will discover and rediscover the wonder of radio, of digital radio DRM.”
