May 5 is more than Cinco De Mayo, the celebration that takes place in many cities across the United States. It is also a special Giving Tuesday event nationwide. It is your chance to lift up local nonprofits, including community radio stations near you.

Giving Tuesday was created in 2012 as a day to encourage people to do support nonprofit endeavors in their communities. Most of us may remember Giving Tuesday as the day that happens later in the year, around Black Friday and Cyber Monday. As with everything in 2020, though, things are changing up.

Over the past eight years, Giving Tuesday has grown into a wider campaign to encourage people to contribute financially, to collaborate and celebrate generosity of others. More than $2 billion has been raised since Giving Tuesday’s inception. Right now, with so many nonprofits in need of help, you can guess money is the most critical conversation.

With all the issues facing community radio, your station would be forgiven for Giving Tuesday to seemingly come out of nowhere for you. Between remote work, automation system management and helping our wonderful volunteers, plenty of leaders in community media are pretty stretched these days.

Hope is not lost. If you are now scrambling to do something for Giving Tuesday, an email to your donors and social media messaging reinforcing core themes to your ask are a great start. Why should a listener give money to your station during a pandemic? That’s not intended to be a provocative question, but one to stimulate ideas about your relevance. It’s your chance to shine a light on the good things you bring your area, and why you are important to support.

In times like this, your radio station aspiring to raise funds could whip up a case for support to explain to a potential donor why you are raising money right now. For instance, maybe your station is seeing a gap in this year’s operating budget because you’ve had to cancel a big fundraising event or your pledge drive. Or maybe your station needs funds to deploy more staff to cover communities most affected by health and economic impacts of COVID-19. Helping everyone to understand your need is central to good fundraising.

If you are shooting to send out that email previously mentioned, consider targeted messages to your reliable donors and the more infrequent ones. You can acknowledge your regular contributors in your language, and ask less frequent donors to step out with you this time. While concerns about personal finances are natural, those able to give are usually willing and wish to be asked. You may want to craft your message appropriately.

The day before, it would be a good move to meet via video conference with your influential people, such as board members, key volunteers and others who can promote your station’s Giving Tuesday endeavors on the day-of. You can talk with them about your plans, but involve them too. They’ll be crucial to Giving Tuesday success, so lean on them for advice and, of course, reaching out to their own networks for contributions.

If you are feeling a little bolder, doing some livestreaming on social media can be fun. Facebook Live with your station’s on-air personalities can be really enjoyable. You could also consider Instagram Live or Twitter for livestreaming, depending on where your station is strongest and where the best opportunities lie. These livestreams can be fun and give listeners a look at the stories of the people who bring the content they love. However, do not do this livestream without a bit of planning. Like live radio, nothing is worse on a livestream than fumbling and dead air.

Giving Tuesday is going to be a fantastic day for many nonprofits. How great it will be for your community radio station is in your hands.

The Federal Communications Commission has elected to eliminate the Engineering Division at the organization in an effort to, as it says, “streamline the organization of the Media Bureau” as part of the public interest.

The commission plans to fold the work of the Engineering Division into the Media Bureau’s Industry Analysis Division (IAD) due to changes in the duties of the Engineering Division.

[Read: FCC Debuts New Seal]

“By incorporating the work and staff of the Engineering Division into IAD, we can better ensure that the bureau’s technical expertise is integrated more fully into the bureau’s adjudicatory matters and policy proceedings,” the commission announced on April 29.

Back in 2002, the Engineering Division was established to conduct technical reviews of media-related matters, including overseeing technical compliance of TV and radio broadcast licenses, as well as things like cable regulatory filings and license transfers. But as the industry transitioned from analog to digital and from paper to electronic filing, the Engineering Division’s tasks have diminished.

Bringing the engineering team into the IAD division will result in streamlined operations and reduce redundancies in management.

There was no word on whether staff cuts will be made. The date that the move will become effective will be set by its publication in the Federal Register.

Nowadays, many people are playing with the Arduino (and clones) and the Raspberry Pi (and clones), sometimes known as Single Board Computers or SBCs. We’ve even heard rumors lately that they’re starting to show up in some of our broadcast equipment, hidden and embedded down inside the case.

Each has strengths and weaknesses. There’s no shortage of opinion about which is better. If you want mine, the Arduino is better for small machine control applications, and the Pi is much better if you need networking, a GUI desktop, and the buzzers and bells. The Arduino isn’t nearly as powerful, but it’s ideal for a dedicated process controller. Because the Pi is a full-blown (if miniaturized) computer, it’s not as suited for real-time processes. In the end, the choice is yours.

The key question for us is whether it’s reliable. You might say, “I can maybe see a print server or ‘smart’ wireless access point in my studios, but will they work at a remote transmitter site in a corn field?”

Yes, provided you protect the inputs and outputs (“I/O”). Modern microprocessor chips are quite reliable, if you respect their limits. Even if your transmitter is a newer model with logic inputs and outputs, you shouldn’t just connect it directly to the pins on the SBC. You’ve also got to watch your input voltages, regardless of surges. For example, if your SBC’s processor chip is running at 3.3V and you connect 5V to one of the inputs, bad things will happen.

There are third-party I/O boards available for the Pi (traditionally called “hats”) and the Arduino (“shields”). They’re a good place to start experimenting, but most aren’t suited for hostile environments. One analog I/O board that we purchased only had 1K surface-mount resistors between the input terminals and the pins on the A/D chip. That did provide a little protection, but there was no way it would handle a strong surge.

WHY USE AN SBC?

The example that I’ll show you in this article could admittedly be done with a recent-model remote control with network connectivity. The better remote controls — and for that matter, many of the latest transmitters — can now send email or text, offer SNMP control and more. But the biggest advantages to the SBC revolution are:

1. SBCs are ridiculously cheap. You can buy several and keep spares on hand.
2. They’re ridiculously small. You can even get nice cases to make your work look pretty.
3. There is plenty of information online; code samples, “how tos” and more. You will probably be able to find an existing project that will do what you want with only a bit of modification. 
4. You can give your equipment precisely what it wants with “smart” logic. For example, you may need to send your transmitter a momentary command when a long-term fault occurs, but the faulting device only provides a constant closure. (The little Adafruit Itsy-Bitsy, which is Arduino-compatible, is ideal for this, by the way.)
5. If your SBC has network connectivity (the Pi does by default; you can add it to the Arduino), it can send email, and/or you can log into it remotely to check on things.

Besides, what if your existing remote control is an older model? What if it has just been destroyed by lightning and you need something right now while you wait for a replacement? Most importantly, what if it’s a special case that your existing remote control just doesn’t address as well as you’d like? (See again advantage #4 in the list above.)

AN EXAMPLE: THE GENERATOR MONITOR

This is an actual Raspberry Pi 3 B+ project that I’ve installed at one of our big FMs here in Alabama. We use a Nautel GV40 transmitter at both of our 100,000 watt FM sites, and for STLs we have dedicated wireless data links. This is ideal for “anywhere access,” because we can (carefully, with a good firewall and some port forwarding) reach our sites over the internet. 

Briefly, here’s the background: Both sites are located at the top of a hill in relatively remote areas. The dirt roads tend to wash out after a storm or have fallen trees block access. The public roads to the main gates are paved, but they can also be blocked by flooding and fallen trees. In a severe storm event, I’m probably on generator, and it’s going to be a while before I can access the site to refuel the generator. To stay on the air, I want to lower power to reduce the generator’s fuel consumption.

Our remote control units are supposed to be capable of doing what I want, but “programming” them is quite time-consuming. It’s not easy to test your work either, whereas with a Pi or Arduino, I can easily simulate the inputs and confirm that it does what I need. 

Long story short, given my background as a programmer, engineer and inveterate tinkerer, I opted for the Pi at one of these sites — less than $50 from Digikey with the “Noobs” Raspian operating system ready to go on an SD card.

The second site uses an Arduino-type processor, and will actually raise and lower the transmitter power automatically. I use a laptop running Linux to monitor the Arduino, and it sends the email. But that’s for a future article; for now let’s just look at using a Raspberry Pi as a standalone monitor. If one of the I/O pins goes low, it will send an email. I’ve set it up so that, if the generator starts running, the program running on the Pi will send a warning. Likewise, once the generator stops running, I get another email. I can then choose to go into the transmitter remotely to lower the power, if I so chose.

LIMITING I/O CURRENT

The key to protecting your Pi or Arduino is guaranteeing that the inputs never see a “hostile” input. That’s the ideal, anyway; we can at least add enough protection to cover us in most cases. This project uses the K827-PH, an opto-isolator available from most supply houses, including Digikey and Mouser. These are typical LED-in, transistor-out units, with four isolators in a single 16-pin DIP package. We only need one opto for this example, but the others are available for later expansion.

Fig. 1: Schematic of the connections between the generator controller and Pi.

Fig. 1 shows the basic circuit for this discussion. This is a simplified version of what I’ve done at the site mentioned above. The whole purpose of isolation is isolation, so I don’t connect the input on the Pi directly to the generator’s “run” contacts. I also do not take the 5V supply from the Pi; that would defeat the purpose of isolation. Instead, I’m using an external 12V supply (in actuality, a simple 12V wall wart) which goes through the generator’s normally open contacts, through a 3.3K resistor, into the K827 isolator.

Look closely at R1 and C3 at the opto’s input. I’ve determined that this is all the protection needed for this particular site. If you have one of those sites that attracts everything from lightning to extraterrestrials with funny hats, you should improve this. Make the capacitor larger. Add a varistor to ground to clamp any high voltages. Split R1 into two 1.5Ks, instead of a single 3.3K, with an extra capacitor to ground in the middle. Add a ferrite or RF choke on the input. I will leave this up to you.

If the generator starts, its normally-open contacts will close, causing about 3 mA of current to flow through the isolator’s LED. This turns on the transistor, which pulls pin 15 low. All we need now is a little program that will check that pin at intervals (I’ve chosen 60 seconds).

Fig. 2: 40-pin IDE-style connector pinout for the Raspberry Pi.

Fig. 2 is the pinout of the 40-pin IDE-style connector provided for I/O on the Pi. At this point, the Raspberry Pi’s documentation can confuse you: there are actually several different naming and numbering conventions for the 40-pin IDE style connector that is provided for I/O. The python library that I’m using wants the “GPIO” numbers. Note that each input can also be assigned different uses, depending on what you’re doing. For this article, we only need GPIO 22 as an input, which maps to pin 15 on the 40-pin connector.

You can download the ready-to-run python program here. Pull it up in an editor and change the email addresses, password, the email server and port numbers as needed. Once you’re done, save the file as genwatch.py, then copy it onto your Pi. In a terminal, in the same directory as that file, enter the command

“chmod +x genwatch.py”

to make the file executable. Now you can run it by entering

“./genwatch.py”

at the terminal prompt, while still in the directory containing the file. The program will continuously check the assigned pin at 1-minute intervals, sending an email if the generator’s status changes. Press CTRL-C to stop the program.

To test it, momentarily short pin 15 (GPIO22) to pin 9 (ground) on the 40-pin connector. You can use a clip lead or a small jumper wire — but be careful! Some of the other pins are directly connected to the power supplies, and you can damage things if you accidentally put 5V on a 3V input, or ground one of the power pins. The classic boo-boo is accidentally shorting pin 1 to pin 2 on that 40-pin connector; you’ll be connecting the 3.3V supply directly to the 5V! You really don’t want to do that one.

I’ve commented the program for you. Python will ignore anything after the hash (#), so comments are a great way to explain what the code is doing. Again, you will need to put in a valid email address and password, as well as the recipient’s email address and the address of your email server. These are also noted in the program.

Get a Raspberry Pi and play with this. You will want the Pi and the Raspian operating system, which is available for download or pre-installed on an SD card. Python will be included with the standard Raspian Linux operating system, so you should have what you need.

More information is available online. You can do a Google search for “Raspberry Pi python” to see a bunch of examples. There are a host of forums available online as well, from the “official” Raspberry Pi forum to special forums sponsored by vendors like Seeed Studio, Adafruit, and others.

If you’re feeling experimental, here’s an idea: Refer to Fig. 2 for the pinouts and try reassigning that “genrun = Button(xx)” line in the program to different GPIO numbers. Then ground those pins; the emails should be sent. For a more advanced example, consider using one of the spare optos to monitor the 12V wall wart itself, and send an additional email if the 12V power supply should fail. In any event, have fun!

Player Editori Radio (PER) released the Radioplayer Italia app for Italy on April 28.

Originally announced in October 2019, the app, available for Android and iOS, lets some 44 million Italian listeners easily search and access their favorite radio station from a single access point, no matter where they are — even out of the coverage area of the selected station.

FASTER AND SIMPLER

Members of the PER consortium include Rai, Radio Mediaset, Gedi, Sole 24 Ore, RTL 102.5, RDS, Radio Italia, Radio Kiss Kiss, Radiofreccia along with organizations Aeranti-Corallo and Federazione Radio Televisioni, which include most local broadcasters.

According to the organization, Radioplayer technology includes faster, simpler and more innovative access to the universe of audio streaming and on-demand offerings, podcasts and offline content of broadcasters.

Radioplayer Italia claims it will not ask the user to register, will make personal data anonymous, will not track listeners’ movements and will not interrupt listening with proposals of any kind.

Furthermore, the content is guaranteed by the broadcasters who will directly supply their own content and associated metadata.

“Radio is once again proving to be the most contemporary medium, capable of making a paradigm shift even in times of crisis” said Lorenzo Suraci, president of PER.

CONNECTED DEVICES

The automotive industry is also involved. Radioplayer Worldwide has been collaborating many automotive brands to design and develop the next generation radio interfaces, accessible through touch dashboards and voice commands.

The Radioplayer data feed will also deliver the Italian stations’ metadata to hybrid radio interfaces in many Audi, VW and Porsche cars. This allows hybrid devices to automatically switch between DAB, FM, and streaming, to keep listeners locked into their favorite radio stations.

Also, says Radioplayer, information coming from this data feed will enable advanced receivers to provide listeners with personalized radio recommendations, search results and catch-up content, in a simple and “natural” way.

Radioplayer Italia will progressively be available on all connected devices. These include smart-speaker platforms such as Amazon Echo, Sonos, Bose, Google Assistant and will integrate with Apple CarPlay, Android Auto, Chromecast, Airplay, Apple Watch, Android Wear and other technologies.

The FCC has updated its official seal ahead of the move to its new offices, featuring new design elements that represent the current state of communications.

The design was a result of an agency-wide contest, with the winning design from Umasankar Arumugam voted for by FCC employees and contractors.

[Read: Pai Explains Commission’s Coronavirus Philosophy]

The design elements include:

• Communication technologies, like satellites and broadcast towers, that are currently impacting the industry;
• Four stars on the outer seal border, which was an element on the original seal of the FCC’s predecessor, the Federal Radio Commission;
• 18 stars on the shield, representing the current number of bureaus and offices in the commission; and,
• The eagle and shield, which identify the FCC as a federal government agency.

The previous iteration of the seal featured a feed line that comes up the middle between a V-configuration of telephone lines. It connects to three horizontal lines, the middle of which connects to two broadcast towers. The other two connect to telephone lines.

Here is a comparison between the previous seal (on the left) and the new seal (right).

The FCC is expected to incorporate the new seal on business cards, stationary, publications, the FCC website and throughout its new headquarters over the next few months. Official use of the new seal will begin when the move to the new headquarters is completed; the move-in date has been delayed because of the COVID-19 pandemic.

“To be sure, Mr. Chairman and commissioners, this is not the time to raise fees.”

So says the leader of the New Jersey Broadcasters Association to FCC Chairman Ajit Pai and the other four commissioners.

Paul Rotella wrote what he called an “impassioned” letter asking that the FCC “hold off on the consideration and imposition of any regulatory fee increase at the next commission open meeting scheduled for May 13.”

He said that an increase in annual fees for broadcasters is not warranted and that “this is certainly not the appropriate time to put any further financial burdens on broadcasters.”

[Read: Hayes Urges FCC Not to Collect Mass Media Regulatory Fees This Year]

The proposed fee schedule calls for about $30 million in fees collected from U.S. AM and FM broadcasters, up from roughly $29 million this year, according to Radio World’s calculation of the FCC data.

Rotella said radio and TV stations have been particularly hard hit by COVID-19, with severe reductions in advertisement revenues. “Most broadcasters have sustained declines of 60–70% in ad revenues, and some have lost even more over the past two months. Indeed, some have had a vaporization of revenue altogether in the last 30 days. Even if the economy were restored tomorrow, it would take months to generate and invoice sponsor revenue, let alone receive it.”

Rotella said that fee hikes, “especially during this time of catastrophic economic upheaval, coupled with the precarious economic forecasts ahead, is simply imprudent and will likely further hobble local broadcasters’ efforts to survive in the aftermath of COVID-19.

“If these snowballing fees force stations to go dark, there’s no other local entity that could ever replace them.”

The commission is expected to consider fees for fiscal 2020 at its May meeting, a total of $339 million across industries.

Jeff Welton says he was lucky enough to find his dream job not far from where he grew up in Nova Scotia, Canada. 

This year’s recipient of the NAB Radio Engineering Achievement Award joined Nautel nearly 30 years ago and has served the broadcast transmitter manufacturer in several roles.

Welton, 55, regional sales manager Central U.S. for Nautel, is a frequent lecturer and expert on digital radio, radio technology and radio engineering. He has written numerous articles and three chapters in the 11th edition of the NAB Engineering Handbook, and even finds time to volunteer at a local community radio station not far from his home, where he provides some engineering assistance. Many know him for his “Tips n Tricks” presentations, delivered with his warm sense of humor — as captured in the title of one called “How Not to Blow Stuff Up.”

The Canadian has been on a bit of a win streak. In 2018, the Society of Broadcast Engineers named Welton the James C. Wulliman Educator of the Year. In 2019 the Association of Public Radio Engineers handed him the APRE Engineering Achievement Award.   

Radio World asked Welton his thoughts on trends in RF manufacturing and where digital radio is headed in the United States.

Radio World: You spent your first 17 years at Nautel in field service and technical support positions. What is the most important current trend radio broadcasters need to know about? 

Jeff Welton: The biggest trend in transmitter manufacturing is IP connectivity. But most importantly for broadcast is the attendant need for IT security, which people are beginning to be made aware of; but it has been a very slow process.  

At work in 2000.

RW: How big of an issue is the security?

Welton: You have seen all of the news of IT ransomware attacks. There are many more hacks and viruses that happen every day that no one ever hears about. Occasionally I will do an Internet of Things search looking for unprotected devices, and if I search audio codes and search a few of the bigger names in codecs, I will find thousands of units online, and half will be using default user names and passwords. That’s the biggest thing right now for broadcasters to be aware of. 

RW: You’re no longer on the design side of the transmitter business, but where does Nautel see RF design going next?

Welton: You certainly see the trend toward smaller footprints. More power density, more watts per cubic inch, so to speak. That trend will continue, but eventually the laws of physics dictate we just can’t get any smaller. Having said that, the laws of physics can always be challenged, and we will going forward.

RW: Any move by Nautel toward a liquid-cooled design for FM/HD transmitter? Some of your competition, like GatesAir and R&S, have been active in that segment. 

Welton: I really can’t answer that question. No comment. That said, we have looked at liquid-cooling repeatedly over the years, going back as far as at least 15 years ago, if not further. We did a 20 kW design in the late ’90s/early 2000s that was liquid-cooled in the initial prototype. 

Ultimately, at that time, we did decide to abandon it for several reasons. Even today, with the advances in the technology, it’s hard to justify the additional cost of liquid cooling in all but the highest power levels, and even then only in specific circumstances. Definitely there are advantages, but the flexibility and lower cost of an air-cooled system typically outweighs those advantages in most cases. 

However, it certainly is situational. What may be the best cost benefit for a 30 kW station in one market may not apply equally to a similar station in a different market, climate or site situation. 

My recommendation to radio broadcasters is to always get a couple of opinions, then try to sort out what provides the best long-term benefits for your station. 

RW: How about all-digital for the AM band. Does Nautel see promise in that market?

Welton: Definitely, we are behind it and support it as a manufacturer. I think it will be good for the broadcast industry, but I’ll qualify that with one thing. It really all comes down to the content, honestly. I think the technology is great and it has promise, but without the worthwhile content and good programming, it is not going to solve any problems for AM broadcasters in the United States.            

RW: You’re known as the “go to” tech support guy at Nautel, yet your official title is regional sales manager. Tell us more about what you do and how much travel is involved.

Welton inspects a newly installed V5 in Wisconsin in 2010.

Welton: I travel anywhere from 100 to 200 days a year. It can vary quite a bit. I have the formal title of regional sales manager, but I pretty much focus on, as they say, “other duties as assigned.” I do seven to 10 state association shows a year. I do NAB of course. I do a half-dozen SBE presentations and some Nautel-sponsored webinars. I even stop in on sight occasionally to help with HD system installs. So I do get to do some hands-on work still.

RW: So you are out visiting facilities and meeting a lot of radio broadcast engineers. What is the most impressive thing you find about that group?

Welton: I think more than anything you find people who willing to be helpful to others, even their competition. You can find people who are competitors but then willing to help others in an emergency and work together. I’ve found that to be the case even during my tech support days.   

RW: How do you think radio can navigate the problem of losing veteran engineers who have a deep knowledge of RF systems? Obviously this affects broadcasters and how they maintain their RF facilities.

Welton: Well, there is a solution, and it’s hard. We need to get young people bit by the bug. Once you get in this industry it really does get into your blood. You don’t see many people leave the industry once they are in it. Where else can you have so much fun and make a living at it? [chuckles] 

I think the pay scale is coming up a bit, but the big thing is tweaking the interest of young folks. That might be hosting an engineering table at a state show career fair. You have to get the exposure to draw interest. There are lots of opportunities for people to be mentored and work part time while being in school still. That’s a great way into the profession 

RW: You perform presentations every year on topics like lightning protection, grounding, transmitter site safety and various other subjects. Is there a topic out there you want to teach?  

Welton: One of the big ones for me is HD Radio, AM and FM, and the implementation. The technology has developed so that I would like to put together a booklet and really dig in how to install and what to look for rather than the theory of the operation of the technology. Really it would be a practical application of HD Radio. So now that it is out there, I’d better get to work on it. 

Jeff Welton calibrates equipment during an AM HD upgrade at WNYC in 2005.

RW: Nautel has for some time thought about equipment beyond transmitters as a way to grow the business. Any new broadcast equipment coming down the pipe?

Welton: Not much I can say on the broadcast side. Much of the work we do outside of broadcast is non-disclosure since we are dealing with the military. We find lots of ways to keep busy and we do a lot of things in RF above and beyond radio, which is cool.

RW: Tell us something about yourself that surprises people when they learn it.

Welton: That I have a fully functioning wood working shop at my home right outside my office. I haven’t been able to work out in it much since I’ve been so busy with work. The last thing I built was a vanity for a bathroom remodel. I did all the cabinetry and built all of the drawers into it. That was cool. It’s a far departure from electronics

RW: Anything else keep you busy at home?

Welton: I love to cook. I spend a lot of time in the kitchen. I got a pressure cooker last year, and loved it so much I augmented that with a second one about a week later.

RW: How did you get your start at Nautel? 

Welton: We had a speaker at my high school one day for career day talking about electronics school in Toronto. I grew up on a farm in Nova Scotia, so as soon as I heard the word “Toronto” I was hooked. He could have been talking about cosmetology school and I would have ended up being a hairdresser. So I went to Radio College of Canada (RCC) for electronics engineering. 

Then I had a few jobs after that, including doing bench repair at Radio Shack. Then in 1990 Kevin Rodgers (now president and CEO of Nautel) was put in charge of building a customer service department for Nautel. By the luck of the draw I ended up there and have been ever since.   

RW: What were your first thoughts upon learning of the NAB engineering award?

Welton: Really of all the people I need to thank for being where I am today. There have been so many people I’ve learned from. Jack Sellmeyer and Tom King come to mind if you are talking directional AM antennas. Gary Cavell has always been willing to answer my sometimes dumb questions. Mark Persons is always willing to share knowledge.   

The one thing I always try to convey to people is that everybody everywhere knows something that somebody else doesn’t. I’ve just been very fortunate to find a bunch of people willing to share the things they know that I don’t. And there is a long list of things. The more I know the more I realize I don’t know it all. Not even close.

GENEVA — The European Broadcasting Union’s Digital Radio Summit 2020 in February focused on possible future models for radio and audio entertainment.

One of the key topics was the future role of integrated radio and multimedia systems in the connected car.

Antonio Arcidiacono is EBU director of technology and innovation. Credit: EBU

During that event, Antonio Arcidiacono, EBU’s director of technology and innovation, presented the keynote speech. He emphasized the relevance of in-car audio content, both linear and not, which would result from the proper blending of broadcast and IP feeds integrated through appropriate, next generation system and user interface.

TRULY IMMERSIVE

Radio World later spoke to Arcidiacono about how he imagines the car will look 20 years from now. He said he imagines himself sitting behind the wheel, finding himself in a type of semi-mobile living room in which the multimedia system welcomes him and understands his present mood.

According to Arcidiacono, the system will know that he has been in the office and so it’ll begin by providing him with the information he is most interested in, followed by a carefully defined progression of content depending on what he’s most interested in.

The driver will then be able to prompt his or her car with something like: “Well, that’s enough news for now. How long is it to get home?” The car will answer the question and then start playing music again based on the mood of the driver as well as any passengers.

“Let me explain,” said Arcidiacono. “I lived in Paris for 30 years and I believe the perfect music to listen to in the car in the French capital is jazz, because the city has a jazz spirit, and people who walk on the street walk with a jazz rhythm,” he said. “This is not necessarily the case elsewhere, so the system would offer an immersive experience that is finely balanced between mood and surroundings.”

On the other hand, if the system understands that his actual mood is tired, maybe he will expect it to play something relaxing like Claude Debussy’s “Moonlight sonata”

BIEN-ÊTRE

In 20 years the car will most likely be autonomous, so there will be no worry about driver distraction. The system will also most likely be able to offer multiple content genres, including visual ones, but always in accordance with the specific situation.

“It’ll be a matter of ‘bien-être’ as the French say,” adds Arcidiacono. “An experience able to offer maximum comfort, and also allow the user to make or receive phone calls.”

In his mind, the system will be able to autonomously detect which calls he will accept and those he won’t, and automatically manage and sort them. In some cases it’ll also be able to answer the phone calls or messages Arcidiacono receives, because it would have learned from him and will know how to appropriately respond to the most common messages and calls.

The idea is that the system will allow the driver to continue living that experience of well-being without interruption thanks to the intelligent behavior of the car and entertainment system.

He continued: “Maybe the system will also be able to understand that I don’t want to go home a certain evening, and it’ll subsequently suggest that it take me to a favorite restaurant.”

The car will also share the same proposal with his wife, who at that moment is in a different place and in a different car. If they both accept, the two cars will bring them to the chosen restaurant where they’ll meet at a table already reserved for them, he suggested.

INTEGRATION

If the first-choice restaurant did not have available space, the system will take care of offering a suitable alternative, again in line with their preferences and the mood of that moment.

“Or it could be that, for example, after leaving work I am going directly to a cultural event instead of heading directly home” Arcidiacono continued. The system will understand that the person is going to that particular event, and then during the ride will provide him or her with an overview of what they’ll see and hear, giving expert reviews so they can make the most of their outing.

This integration between information, entertainment and education, which has always been the three fundamental pillars of broadcasting, will therefore continue in the future. Arcidiacono sees them as increasingly integrated with each other.

However, if at a certain point the driver decides they don’t want the assistance, the person can simply say something like: “Leave me in peace because I want to think and have quiet time,” The car will then understand.

Speaking about the user interface, Arcidiacono thinks most of the buttons will have disappeared. “Maybe there will be only one button to turn everything off if the driver gets nervous, because being in control is also a natural feeling. A big red button to push to say to the system ‘Stop it!’ might be useful,” he concluded.

Daily radio listening represents more than 60% of consumer media consumption worldwide — surpassing even television and content streaming in many markets.

The recent “Digital Radio Vision for India” workshop, held Feb. 12, offered an optimistic view of how India, through its “Digital India” initiative, can capitalize on the nation’s growing radio broadcasting industry.

Xperi was on hand to present its vision of how HD Radio, can support the radio industry’s transition from analog broadcasting to a significantly more robust and diverse digital broadcast platform.

Today some 2400 radio stations in several countries use HD Radio to reach more than 400 million people across North America and other countries in Asia, Europe, and Africa.

But, as the workshop outlined, while HD Radio is helping revolutionize and digitize radio services around the world, India is lagging far behind, with most of its radio stations transmitting solely in analog. The good news is that HD Radio offers All India Radio and private broadcasters an opportunity to accelerate and become world leaders in digital radio networking.  It simply makes sense.

Here’s Why:

Clear Audio, Diverse Programming, Multimedia

HD Radio allows radio stations to transmit multiple programs and other information with quality audio and robust and diverse content. While the analog transmissions that currently dominate radio in India provide listeners with music, news, or talk shows on their radio receivers — each analog radio station broadcasts only one audio program per frequency.

HD Radio, on the other hand, enables radio stations to utilize advanced technology to send multiple audio programs digitally with higher sound quality, as well as to include associated and relevant digital content and images.

For example, a digital radio receiver or mobile phone can automatically tune to digital radio programming and enable users to select from multiple audio programs on the same frequency, all while still receiving older, analog-only broadcasts.

 HD Radio Can Bring India Together

India has a diverse population, with over 23 different languages and a very mobile population. Radio listening happens on-the-go. HD Radio enables the simultaneous broadcast of programming in multiple languages and allows broadcasters to communicate national, regional, and local information on separate audio channels, as well as offering diverse programming in large urban markets like Delhi and Mumbai.

In addition, it’s possible for the government’s All India Radio broadcasts to transmit the Prime Minister’s monthly Mann Ki Baat message in multiple languages. To access this content, India requires digital radio solutions for mobile handsets, such as the BeatBoy HD101 cell phone sold in the Philippines.

Community-building, Government Communications and Emergency Alerts

As well as offering India’s listeners a multimedia experience, including program-related pictures synchronized with the audio, HD Radio enables listeners to stay in touch with their specific communities through localized entertainment, information, and talk radio shows. These incude emergency notifications and alerts to warn and inform local residents of events such as storms, fires or other threatening disasters in multiple languages.

The HD Radio system can integrate with India’s National Disaster Management Agency alerts infrastructure by importing CAP-formatted alerts into the digital broadcast chain.  These digital emergency alerts can provide critical notifications and text alerts to HD Radio enabled devices, which will “wake up” on detecting an alert message.

Also, HD Radio can help the government notify the public of non-critical information, such as reports on health and environmental matters from various ministries. For example, All India Radio can partner with the Ministry of Environment, Forest, and Climate Change to provide hourly notifications on air quality index using text and graphic notification transmitted to HD Radio receivers.

Digital India Initiative

Because it is an effective way to reach the general public with audio communications, including sending information and data to millions of devices for infrastructure and IoT services, HD Radio system can help India’s radio industry and businesses. Through the Digital India Initiative, HD Radio can facilitate the development of new applications for local services to enhance control and management of infrastructure and the power grid, send traffic services to trucks and cars to improve navigation and reduce congestion, and access IoT devices with secure unidirectional smart-messaging and control.

The Time is Now — Digital Radio and All India Radio

With adults globally listening to an average of 90 minutes of radio a day, it is clear that radio is here to stay, but only so long as it adapts to the digital consumer. India has half a billion of those digital consumers and the opportunities for increasing the scope of radio communications, both locally and nationally — all while improving the radio experience — are significant, and potentially of major benefit to India’s population.
