Good news from Nielsen, but BIA/Kelsey report is a cautionary tale for those counting on digital revenue

Like reported sightings of Bigfoot, and fanciful stories regarding unicorns, claims over the death of over-the-air radio aren’t based in reality, at least according to Nielsen

The company reports that each week, more Americans tune into AM/FM radio (93%) than watch television, or use smartphones, tablets or computers. “At the same time, digital streaming offers consumers even more ways to listen across many of those same devices,” they write. “Audio plays a central role in the daily lives of hundreds of millions of consumers. Broadcast radio specifically continues to profoundly enrich the lives of listeners and create value for advertisers.”

That’s the good news. Let’s also examine the news that’s not so good. According to BIA/Kelsey , the digital advertising income of U.S. radio stations showed a 9.7% increase year over year, but during the same period over-the-air radio showed a decline of 2.0%. (More details are shown in the first quarter edition of BIA Advisory Services’ 2018 Investing In Radio Market Report .)

Overall the industry experienced a 0.2% drop from 2016 to end the year at $13.87 billion.

“Although local radio stations are still important players in their local markets, we do not expect the over-the-air advertising revenue of U.S. radio stations to grow much this year or in the near future,” said Mark Fratrik, SVP and Chief Economist, BIA Advisory Services. He said the number of new audio and entertainment sources will provide continued competition for radio, which of course has a negative effect on ad revenue.

The game is still ours to lose. “It’s an aggressive environment that competes for audiences with local radio,” Fratrik writes.

HD radio technology is also mentioned in the report. “The radio industry is attempting to build out digital channels to reach local communities, but they are also focused on overall platform improvements,” writes Fratrik. “Opportunities for local radio stations include the further adoption of HD Radio technology to transmit their programming and add subchannels for additional programming. With car manufacturers including HD Radio receivers in their new cars, radio has a fresh opportunity to impress advertisers and consumers.” According to BIA data, as of January 2018, 211 AM and 1,980 FM stations were broadcasting an HD Radio signal.

The same report also said that another “strong opportunity” being employed is the increased use of FM translators for rebroadcasting AM signals, and that new technologies including NextRadio open up new avenues for revenue growth.

FMXi 4g provides dynamic time and audio correction

MASON, Ohio — GatesAir will introduce its FMXi 4g and other new HD Radio enhancements for audio and data transport at the 2018 NAB Show, April 9–12 in Las Vegas.

In addition to “virtually eliminating maintenance through a fully embedded architecture that combines both functions” the new FMXi 4g is the first HD Radio Importer/Exporter solution to provide dynamic time and audio correction.

“Diversity Delay is a critical component of the HD Radio listening experience…the GatesAir-exclusive algorithm inside the FMXi 4g ensures proper time alignment between analog (FM) and digital (HD Radio) signals, and improves the listener experience by removing the objectionable blending artifacts” according to the company.

The removal of a standalone, computer-based Importer or Exporter eliminates the boot-up process, removes moving parts and frees broadcasters from “troublesome PC-based applications.” HD Radio implementation is simplified by “integrating the Importer and Exporter and eliminating complex external networks, clocking and GPS references between disparate systems which, substantially raises the possibility of packet loss and other imperfections,” according to the company.

GatesAir will also demo how its new Intraplex IPConnect device for reliable and secure data transport can more effectively manage large data payloads across the E2X connection.

“The seamless integration of IPConnect into the Gen4 architecture smooths the very heavy signal bursts that are common across the E2X path,” said Rich Redmond, chief product officer, GatesAir. “The quality of service significantly improves through a reduction in dropouts and buffering instances that have long challenged HD Radio broadcasters.”

The demo will feature a total of 12 HD Radio audio services from a single transmitter

LAS VEGAS — The NAB is planning a live demo of all-digital FM HD Radio featuring a total of 12 HD Radio audio services from a single transmitter during the show next month. The demo will feature a Nautel transmitter with Beasley’s KKLZ(FM) serving as the test station.

The demo will be available during regular NAB Show hours, according to Nautel officials. The special demo is tied to a session during the Broadcast Engineering and Information Technology Conference that will detail extensive high-power field testing of all-digital FM conducted earlier this year in Las Vegas using the Beasley station. Pilot, the NAB technology and innovation initiative, is hosting the session, “All-Digital FM Field Test Project” on Sunday, April 8, from 1:50–2:10 p.m.

The digital audio channels will be on even-numbered frequencies, so most receivers cannot get these. Attendees can go to the Pilot booth in the Futures Park section of the NAB Show where receivers will be tuned to the even-numbered channels.

Up until now only limited field testing of all-digital HD Radio has been conducted with low transmit power (100W) and reception equipment in non-real world test conditions.

KKLZ’s IBOC signal during the NAB Show will be based on the Nautel all-digital HD multiplex signal composed of three interleaved IBOC sidebands, according to Philipp Schmid, Nautel research engineer.

“To maintain KKLZ’s regular program service, the center sidebands are muted and replaced with the analog FM carrier. The result is two independent IBOC sidebands on both sides of the analog FM signal for a combined bitrate of 394 kbps (over 3.2x standard IBOC capacity), providing up to 12 HD Radio audio services plus the analog FM signal all broadcast by a Nautel GV40 transmitter from the Black Mountain transmission site,” Schmid wrote in an email to Radio World.

The experimental nature of the digital carrier consists of a “several minute-long loops of audio content” and is intentionally placed on the “even” dial positions, according to Schmid.

“The four digital sidebands will be available on 96.0, 96.2, 96.4 and 96.6 MHz that are not normally associated with standard FM radio stations and are receivable on some commonly available HD Radio receivers,” Schmid said.

Meanwhile, KKLZ’s regular FM programming will be available on 96.3 MHz with its regular HD programming suspended in favor of the special signal broadcast under experimental authorization, he explained.

Powerlite DCR-T enters HD Radio and LPFM markets

RAYMOND, Maine — Antenna-maker Dielectric says it has adapted its Powerlite DCR-T antenna for the special needs of HD Radio and LPFM broadcasters. The key, according to the company, is added control of directionality.

The circularly polarized DCR-T directional antenna is offered as a cost-effective solution for low-to-medium power FM and translator stations, which traditionally required a far more expensive antenna in designs typical of higher power operations, to meet directional pattern requirements.

[Exhibiting at NAB Show? Nominate a product here for Best of Show Award consideration.]

Dielectric says this is possible because special software reduces antenna costs and production lead times, and with most FM translator directional antenna requirements, significantly reduces the price of the FCC proof of performance. The software that provides the proof of performance data required to confirm directional pattern compliance, as opposed to the traditional method of verifying patterns with physical scale models.

Dielectric Sales Manager Steven Moreen said, “The ring-style design of the DCR-T antenna, with its stable axial ratio independent of impedance tuning, is an ideal platform on which to add directional signal control. And, given the efficiency at which Dielectric can produce these antennas, the antenna can be delivered within weeks as opposed to months, along with the associated FCC proof of performance.”

The company adds that the DCR-T’s broadband capability offers enough bandwidth to accommodate HD Radio signals alongside analog FM, with in-field channel adjustments should channels change. The low-profile design offers less wind resistance. An optional radome is available.

FMHD-1 mod monitor gets AE management tweak

WEST CHESTER, Pa. — Belar’s well-known FMHD-1 HD Radio-capable modulation monitor is receiving a software update that will allow it to decode and monitor the presence of Artist Experience graphics in the RF stream.

Belar’s new WizWin software will automatically manage bandwidth-heavy image data, while providing broadcasters with a diagnostic tool to monitor the health and status of the Artist Experience data stream. The software recognizes the receipt of Large Object Transmission data encoded in the HD Radio signal, and decodes the image for display on a desktop or laptop workstation in alignment with text-based Program Associated Data such as artist name and song title.

After decoding and processing images, the monitor communicates with the WizWin software to translate the image display on a PC. This ensures that engineers can monitor the presence and proper timing of graphics, and also visualize the full color palette to confirm image quality.

Belar CEO Mark Grant notes that simple HD Radio receivers such as car radios are not adequate to provide the detailed level of monitoring needed. “Without the built-in diagnostic tools of the modulation monitor, there is no simple and immediate way to understand what is happening if the graphic fails, and the service defaults to a station logo, for example. WizWin provides our customers with a complete solution to decode, process, display and monitor Artist Experience data from virtually any location.”

Sam Matheny and Joe D’Angelo addressed the future of radio technology at event in Switzerland

GENEVA — More than 120 delegates attended the recent Digital Radio Summit — part of the annual EBU Digital Radio Week — to hear from EBU members and others about the present and the future in radio technology and innovation, according to tech.EBU .

For those readers in the states that perhaps wonder just why we cover European radio so much, it’s because broadcasters over there are in many ways ahead of us and we can learn something about what will happen in North America by seeing what happens there.

A primary theme running through the summit this year was “user experience,” including automotive and voice control. Questions that kept coming up included: How can radio compete with the user experience offered by other audio services? What can radio do to go even further? And how can broadcasters actually drive change, rather than be swept away by it?

Are we asking these same questions enough in the US? The good news is that US broadcasters were in attendance and spoke to the assembly. Sam Matheny, CTO of NAB , said that broadcasters were currently fragmented, but trying to work with global companies — and that coming together and using scale to leverage change could be the winning tactic. He also pointed out that something as simple as using the same words on a global scale would help to drive this change. 

Matheny reminded attendees that in times of crisis, people continued to turn to radio as their primary source of information, as witnessed during tragic events such as Hurricane Harvey in the US or the Tōhoku earthquake in Japan. It was this reliability of broadcast over mobile networks that drove the NAB push to get broadcast receivers in mobile phones, said Matheny, according to the same article.

Radio remains of vital importance in cars and accounts for a huge proportion of listening hours through the world. The experience of radio in cars is evolving, though. 

Joe D’Angelo of Xperi called these changes “table stakes” that radio must offer to keep its prominence in the dashboard. Presentations from Xperi and Audi illustrated that graphical branding and information about what is on-air enriches the radio user experience, and Audi issued a call to action for broadcasters to provide logos, content and metadata to feed their increasingly sophisticated and capable in-car media surfaces.
