Can an App Solve the DRM Receiver Problem?

Radio World
5 years 4 months ago

The Digital Radio Mondiale standard for digital broadcasting in long, medium, and shortwave bands offers the possibility to transmit audio, text and pictures.

At work on the DRM app in AlgorKorea’s offices. Images courtesy of Dr. Soon S. Jarng, CTO, AlgorKorea.

A few broadcasters use DRM for both domestic and international transmissions. DRM’s largest problem is lack of receivers, especially affordable standalone ones.

Some listeners use an SDR, computer and free Dream software to receive the DRM signals, but this audience doesn’t make up the mass audience that broadcasters are looking for.

A FEW ISSUES

In addition, the Dream has two serious limitations: It can’t receive the latest DRM codec (xHE-AAC) and its current version is unable to receive MOT Slideshow.

Many international broadcasters will not commit to DRM transmissions because of the lack of receivers. There is an effort by some broadcasters to coordinate the purchase of thousands of standalone DRM receivers in the hope that this will jump-start the market for receivers. This effort is rather capital-intensive, however.

There are millions of Android and Apple smartphones and tablets already in use. What if they included an app that could receive DRM? What if that app could be coupled to the SDRs already in the hands of listeners?

A South Korean company, AlgorKorea, has developed a series of apps to do just that. AlgorKorea is best known for developing hearing aid firmware, according to Dr. Soon S. Jarng, CTO and founder.

HOW IT WORKS

AlgorKorea didn’t develop the apps with the intention of solving the DRM receiver issue. They developed them to resolve a problem with FM hearing aids used in classrooms.

So how do they work? The DRM+SDR version couples the popular and inexpensive RTL-SDR to an Android device with a USB OTG adapter.

The diagram shows how the DRM+ app connects to a phone or tablet.

The DRM+ app is compatible with both Android and Apple devices and couples to the SDR using audio cords. A common and inexpensive resistor/capacitor needs to be soldered into one of the cords.

The app can receive MOT Slideshow, DRM texts and Journaline, a text news/information feed. AlgorKorea says it’ll continue to develop DRM apps. “We’re working on another new app (an inexpensive SDR dongle) for the Msi SDR Panadapter, added Dr. Jarng.

Apps will play an important role in solving the DRM receiver problem and Algor’s offerings appear to be just the beginning.

Hans Johnson has worked in the shortwave broadcasting industry for over 20 years in consulting, frequency management, and sales.

Senate Passes PIRATE Act

Radio World
5 years 4 months ago

Opponents of illegal broadcasting scored a major and long-anticipated victory today: The Senate (finally) passed the PIRATE Act Wednesday.

Short for “Preventing Illegal Radio Abuse Through Enforcement,” only one hurdle remains for S.R. 1228: President Trump’s desk. 

The legislation also represents a coup for FCC Commissioner Michael O’Rielly, who has championed the anti-piracy enforcement actions recently.

In response to the act’s Senate passage, National Association of Broadcasters President/CEO Gordon Smith said, “This legislation provides stronger resources to help the FCC combat illegal pirate radio operations, which not only interfere with licensed radio stations but also public safety communications and air traffic control systems. We look forward to the President signing the PIRATE Act into law.”

[Six Things Broadcasters Should Know About the PIRATE Act]

In February 2019, the PIRATE Act was unanimously passed in the House of Representatives for the second time. The anti-piracy bill was first introduced during the 115th Congress and passed in July 2018, but it wasn’t taken up by the Senate until 2019.

U of Arkansas NCEs Admit to Underwriting Oops

Radio World
5 years 4 months ago

A pair of noncoms licensed to the University of Arkansas will pay a $76,000 civil penalty after admitting to violating the FCC’s underwriting laws.

KBPU(FM) of De Queen, Ark., and KTYC(FM) of Nashville, Ark., will also implement a five-year compliance plan coordinated with the Enforcement Bureau.

Both noncommercial education stations are managed by Cossatot Community College of the University of Arkansas.

In September 2016, KBPU(FM) and KTYC(FM) ran multiple announcements that “promoted their for-profit underwriters’ products or services and contained qualitative descriptions and comparative language, pricing information, and/or calls to action” over the course of three days. A complaint with a transcript was filed (EB-IHD-17-00024914) against the university. As part of the consent decree, the university admitted that the transcript is accurate, despite retraining staff on underwriting rules.

The University of Arkansas will now be required to make four payments of $19,000 to the U.S. Treasury and will also file regular compliance reports to prove they are taking steps to ensure these violations do not occur again.

The order was adopted and released Jan. 7. Read the order and consent decree (DA 20-12) here.

Hybrid Radio Breaks Out 

Radio World
5 years 4 months ago
Bob Dillon

The author is senior vice president, Connected Radio for Xperi.

Not long ago, Gene “Bean” Baxter said goodbye to KROQ(FM)’s “The Kevin & Bean Show” after 30 years on the station’s signature morning drive-time show. He left behind a legacy that stretched across generations of listeners and traveled far beyond the Los Angeles basin. It’s fair to claim, in fact, that the “World Famous KROQ” lived up to its tagline in part due to the magic of shows like this one. 

It also raises two very good observations about the power of radio: that there’s something tangibly personal and rich about the broadcasting, and that as the world grows smaller —  radio becomes more inclusive and empowering. 

After all, one doesn’t have to be from Los Angeles to appreciate Kevin & Bean. The value and the significance of the content produced travels far beyond one spot on the map. In fact, it’s possible that the power of radio —  personal and real entertainment – has never been greater. That’s good news for everyone who values access to rich content — and the ability to choose what they’d like to consume.  

ENTERTAINMENT OPTIONS ARE ENDLESS

Creating choices for entertainment is perhaps greatest inside your vehicle. Inside the cabin of today’s newer cars is a plethora of options, all of them good. You can connect your personal device via Apple CarPlay or Android Auto; there are satellite networks that deliver programming in hundreds of different ways and categories. On-board apps abound, full of playlists that continuously pump the music at you 24/7. 

The DTS Connected Radio Live Guide shows Now Playing information for each tunable station, enabling station choice based on what’s playing.

Then there’s radio. And it’s a stronger option today than ever before, thanks to the widespread adoption of HD Radio and the emergence of hybrid radio.

Our version of hybrid radio is DTS Connected Radio, which combines over-the-air broadcasting (analog, HD Radio and DAB+) and corresponding metadata (via IP) on a global scale. This convergence creates three very important benefits: 

Deeper and more fulfilling content for users: The combination of data with broadcast enhances the discovery of quality programming. In fact, one of the challenges around broadcast radio going digital is choice — especially in North America with HD Radio, where multi-casting has expanded the number of sources by over 2,000 stations. In addition, today’s modern digital platforms give users the ability to search via many different ways, including voice activation. Hybrid radio also provides that level of enhanced discoverability. There’s a rich visual interface so you can search for content, and the availability of information for all radio stations in a market in under one second. It combines the search-and-sort value of online experiences with higher quality radio programming available in the user’s market.

Affordable change at a global scale for automakers: There’s no mistake that the car dash is changing, getting more complex and more expensive. There’s increased connectivity and hardware, along with new regulations in Europe — and probably soon in North America — that require a module that’s basically a cellular modem in the car for emergency response. Hybrid radio leverages what automakers already are legally required to have as a part of their vehicle technology offerings. The only service that that can deliver that level of affordable infotainment inside a vehicle is radio. Automakers have already made an investment in the digital tuner; they’re now also required, in certain markets, to add a connectivity module for regulatory purposes, and emergency response. Hybrid radio brings these two components together, leverages the investment and creates enhanced radio — the only truly free medium. Automakers can now deploy an enhanced content platform through investments that they’ve already made — with broadcasters who are already on board. It’s affordable, rich content on a global scale, a single radio platform that delivers a consistent and enhanced user experience across analog, HD Radio, or DAB+ radio.

[DTS Promotes “Connected Radio” Project]

Sharper listener insights for broadcasters: The value of metadata doesn’t stop at the album name. Indeed, the real value is in user listening habits. For DTS Connected Radio, once the car is turned on the radio immediately connects to our service. Let’s say a session starts with a vehicle in Los Angeles. We know the radio station, and how long they listen before jumping to another station or service. All the while, we’re sending data to the user, creating a two-way feedback flow that we measure and send back to the station. The radio station can learn why they tuned in, and what made them leave. Did they tune to another radio station? Shut off the car, or did they drive out of coverage? How long did they listen? Ultimately, that’s all available audience flow data over time. Hybrid radio — at least DTS Connected Radio — is able to provide a measurement of their total audience and how that audience flows in and out of their station throughout the day. 

A DTS Connected Radio Now Playing screen shows image and text for currently playing content along with station metadata.

Overall, DTS Connected Radio enables automakers to create a common experience across analog and digital broadcasting. It pairs broadcast programming with IP-delivered content, all from the vehicle’s IP connection. The combination of analog programming and its corresponding metadata creates a richer, more valuable content experience — and one that’s affordable at a global scale for automakers. 

There’s a very real quality to the content that radio brings to listeners. Globally and regionally, it’s a vital part of how we enjoy life and expand our own personal horizons. Radio is unique in that way. As it moves forward toward a hybrid system of digital information and broadcast programming, it is evolving into a scalable format that brings the best of those real moments to an on-demand and two-way system of information sharing — done across a digital, affordable and global platform.

SBE’s Poray to Retire in 2020

Radio World
5 years 4 months ago
John Poray

After nearly three decades of service, Society of Broadcast Engineers Executive Director John L. Poray has announced his pending retirement.

According to an SBE press release, Poray will step down at the end of this year. SBE President Wayne Pecena will work with the board of directors to find a new leader for the organization. However, Pecena said in the announcement that “John has been a fixture of the SBE since 1992 who cannot be replaced. We can only seek to find a successor!”

The SBE was founded 56 years ago, and Poray has been with the society for more than 27 years. Under his leadership, the society increased its membership to more than 5,000 members and 115 chapters spread across the U.S. and Hong Kong, as well as SBE members located in 25 other countries. During Poray’s long tenure, SBE also added to its certification, education and frequency coordination programs.

[Background on SBE EAS Advisory Program]

Poray said he looks “forward to a busy 2020” and says he will assist the board during the transition.

“I have been blessed to have had a long and productive relationship with the SBE, working with many great members, chapter and national leaders and staff,” Poray said in the release. “Together, we have worked to grow the SBE in size and stature and I believe the SBE is positioned well to continue to serve the broadcast and media engineers into the future.”

Prior to taking the helm as the SBE’s first full-time executive director, Poray spent more than a decade in other nonprofit organization management roles. He is a certified association executive. Poray began his career in with the Boy Scouts of America’s Central Ohio Council and went on to work for Kiwanis International, The Apartment Association of Indiana and The Columbus Apartment Association.

WorldCast Sets Up New Office in Malaysia

Radio World
5 years 4 months ago

WorldCast Group will open a new office in Kuala Lumpur, Malaysia.

The group, which comprises WorldCast Systems and CONNECT, explains that it chose Kuala Lumpur for its new office because of the city’s strategic and central location.

Kuala Lumpur, it says, is ideal for providing customers and partners in the Asian market with the “best” local service.

The new WorldCast Group office will officially open mid-January. Victor Bidot, regional sales manager and Bastien Bahuet, pre-sales engineer will use the new location as their base.

Christophe Poulain

The expansion, says WorldCast, consolidates its global presence, which now generates 85% of its turnover from exports.

“For several years now, we’ve had a sales representative in India and with an increasing number of opportunities presented to us in Asia, especially China, Japan, Korea and Southeast Asia,” said Christophe Poulain, co-President of WorldCast Group. “We are enthusiastic about establishing this new office in the region.”

Starks: Tech Advancing People’s Lives, But Caution Still Needed

Radio World
5 years 4 months ago

Speaking in front of the Consumer Technology Association’s Government Affairs Council, FCC Commissioner Geoffrey Starks took the time to recognize many of the biggest tech advancements being made today, but rather than just marvel at them, took a critical look at where they are coming from and how we may need to protect ourselves against them.

Giving his speech on Jan. 6 before the official start of the CES 2020 conference, Starks laid out what his primary goals will be for 2020: “… ensuring that our communications networks and technologies support security, privacy and our democratic values.”

[Read: Starks Criticizes FCC Record on Media Diversity]

Starks brought up many different forms of technologies that on the surface prove beneficial to our everyday lives — entities accessing our data for more personalization; algorithms that can help classify and research topics based on data and past trends; and facial recognition technology for increased security. But he also offered instances where all of these technologies can prove dangerous, abused or misleading.

“We must undertake, right now and continuously, the thorough examination of all these new capabilities to decide now how we will ensure that they are all poised to serve a future that creates opportunities instead of reinforcing existing inequalities,” he said.

He also brought up the potential danger he sees in China. He notes that he has been working to remove equipment provided by Huawei and ZTE from communications networks because he says there have been instances when such equipment transferred secure data to the Chinese government. He also says that technology developed in China is often not taking into consideration the civil liberties that are required for nonauthoritarian regimes.

Potentially helping alleviate much of this, according to Starks, will be 5G.

“I am optimistic that technology developments, especially 5G standards, will support our efforts to improve network and data security,” he said. But still, it will fall on people to make sure that the new technology meets the appropriate standards.

He added, “If we work together, I am confident we can build a future that is more advanced, more secure and more prosperous, and more equitable for all.”
