Sage EAS Users Get a Deadline Extension From the FCC

Radio World - Tue, 11/28/2023 - 13:43

Users of Sage equipment: You now have another 90 days to meet that pending FCC deadline for updating your EAS firmware.

Users of EAS products from other vendors: The Dec. 12 deadline still applies to you.

The chief of the FCC’s Public Safety and Homeland Security Bureau has issued an order in response to a request from REC Networks and the National Association of Broadcasters.

REC and NAB had asked for an extension of time for stations to comply with the requirement that participants in the Emergency Alert System, including broadcast stations, prioritize the Common Alerting Protocol-formatted version of an EAS message when they receive both a CAP and legacy version of the same alert. The deadline for EAS participants to comply is Dec. 12. For most participants, that means updating their equipment’s firmware.

But as we’ve reported, Sage Alerting Systems recently the commission and its users know that it would not be able to release the necessary firmware update in time.

The FCC noted that Sage serves a significant market share of the market, and it accepted the argument by REC and NAB that “hundreds, if not thousands, of EAS participants must update their firmware by the same deadline” and that multiple broadcasters requesting simultaneous updates to their systems would create a heavy volume of urgent requests, making it impracticable for all participants to comply.

So the FCC says that Sage users will now have until March 11, 2024.

“We deny, however, the extension request to the extent it requests a waiver on behalf of all EAS participants. … The extension request does not provide a basis for granting a blanket waiver to all EAS participants, nor do we believe it would serve the public interest to extend the deadline where circumstances do not warrant it.”

Manufacturers Digital Alert Systems and Gorman-Redlich released software updates to users last month. Viavi (Trilithic) issued an update earlier this year.

GBS Testing in India Will Start With Bangalore

Radio World - Tue, 11/28/2023 - 13:17

Officials from GeoBroadcast Solutions and India public broadcaster Prasar Bharati met in New York City this fall and gave an update on the deployment and testing of GBS technologies in that country.

Aditya Chaturvedi, deputy director general of Prasar Bharati, provided a comment to Radio World by email through GBS. 

“ZoneCasting and MaxxCasting are seen as wonderful and invaluable technologies by the Indian government. Given the geographical vastness and cultural diversity of India, they recognize the tremendous potential these technologies hold.”

As we reported earlier this year, the technologies have been authorized for deployment and testing in New Delhi, the capital, and Bangalore, often called the Silicon Valley of India. Each area has more than 10 million residents. ZoneCasting enables the targeted delivery of content to geographic zones. MaxxCasting extends the reach and coverage of FM radio, improving reception in challenging terrains.

Shown in New York are Ryan McGinness of R&R Partners; Christopher Devine, GeoBroadcast Solutions; Dr. Ben Chavis and Tish Bazil, media personalities, educators and community leaders; Nitu Chaturvedi and Aditya Chaturvedi of Prasar Bharati; Dev Viswanath, Geo Global Banad Pvt. Ltd.; Bert Goldman, Goldman Engineering Management; and Gerry Waldron, Covington & Burling LLP.

“India’s cities are as diverse as 10 countries, making this technology exceptionally beneficial,” Chaturvedi continued. “It allows us to address our regional populations using a single transmitter and broadcast. Although we are in the early testing phase, we intend to deploy this technology at prominent installations of Prasar Bharati, such as Delhi and Bangalore. Our goal is to assess its performance and ensure it doesn’t interfere with our original transmission.”

He said numerous dialects are spoken across hilly terrains in India, making the technology suitable for providing tailored broadcasts to small yet significant populations. 

“Prasar Bharati is one of the largest radio broadcasting organizations globally, with over 500 broadcasting stations and more than 200 program-producing stations,” he said.

“Despite this extensive network, we still struggle to meet the diverse needs of our public. With these technologies, we can reduce our reliance on numerous program-producing stations and, instead, centralize our content delivery to cater to the varying dialects, languages and population requirements across India. … Though our testing has just begun, the technology is already demonstrating its significance in the context of our rich Indian culture.” 

The testing will commence in Bangalore before expanding to Delhi and overlapping with Faridabad. Assuming these deployments proceed smoothly, subsequent steps would involve discussions on wider implementation of ZoneCasting and MaxxCasting across other cities, mountainous regions and border areas, according to Dev Darshan Banad Viswanath, managing director of Geo Global Banad Pvt. Ltd., which was created to introduce the technologies in India.

“Additionally, we will explore the possibilities of forming partnerships for commercial deployment with private broadcasters throughout the nation,” he said.

Bert Goldman, chief engineer for the ZoneCasting and MaxxCasting initiatives in India, was among those who participated in the New York meeting.

Capitol Broadcasting Doubles Ad Revenue on SoundStack

Radio World - Tue, 11/28/2023 - 12:55

Radio World Buyer’s Guide articles are intended to help readers understand why their colleagues chose particular products to solve various technical situations. This month’s articles focus on products that support streaming, podcasting and online content delivery.

With a slate of popular broadcasts and podcasts, Capitol Broadcasting, based in Raleigh, N.C., works hard to ensure its shows earn as much ad revenue as possible so they can continue to inform and entertain their avid listeners. 

Adding new programmatic demand partners to fill more inventory was difficult; Capitol needed a monetization partner that could also connect them to incremental advertiser demand easily.

Also, using two different systems to manage streaming and podcasting, Capitol’s team was doing extra work to traffic, optimize and analyze their ads and audience. Getting a single and simple view of overall performance was difficult.

Jon Accarrino is VP, transformation and strategic initiatives for Capitol Broadcasting.

“Managing streaming and podcast distribution from separate platforms created needless duplication in reporting and ad scheduling. We wanted a single platform that could manage both,” said Anita Normanly, director of podcast operations.

Capitol moved streaming and podcast delivery/monetization to SoundStack in the fall of 2022. Opening up its audio inventory on an independent platform, with direct connections to multiple demand partners, Capitol ensured that more advertisers would have access to the audiences they value the most, allowing them to fill more inventory. The organization more than doubled ad revenue  in five months by selling each impression to the highest-paying advertiser.

The move allowed them to unify management and reporting, of both podcasting and streaming, in one system, cutting workload in half. It also gave Capitol access to features like reliable geotargeting, blackouts for exclusive sporting events and provide targeted emergency alerts.

AEQ Adds SmarTalk Service

Radio World - Tue, 11/28/2023 - 12:30

AEQ says its new SmarTalk web-based management portal generates links to be sent to a correspondent by email, WhatsApp, QR code or other means.

“When the correspondent clicks on the link, a browser opens and connects to the station’s AEQ Phoenix audio codec, sending Opus-encoded audio to it,” the company states.

“Without further intervention, the audio link between the device’s microphone and speaker or headset and the station’s audio codec is ready.”

It said you don’t need to have an audio codec or install software. “Sporadic collaborators can broadcast from anywhere there is internet connectivity.”

The participant receives the link and clicks it to see a welcome screen. With a second click, the person can participate. “Sending a reporter or a mobile unit, or moving the guest is avoided, as they use their own computer or smartphone to connect and participate.”

Users of AEQ Phoenix audio codecs can request a trial of the SmarTalk service, which is available under a renewable license that can be purchased based on the number of audio codecs per studio to be enabled.

“Subscribers can make any use of the service as they see fit, and send their connection link as many times as they need during the subscription period, for the number of licensed Phoenix audio codecs.”

When a license is activated on a PC at the station, the web application is activated so that SmarTalk users can create the “Guests” or users of remote terminals, send them the links, assign calls to audio codecs and put them on the air. An administrator window is used to register or modify stations, codecs and other users. 

If SmarTalk is enabled for a Venus 4 Phoenix codec, individual audio codec channels can be preset to SmarTalk, allowing a studio audio codec to dynamically work with SmarTalk or other portable audio codecs. In other Phoenix audio codecs, channels can be assigned to the service manually.

AEQ says that to ensure availability and low delay, redundant infrastructure was designed across several cloud servers in different regions of the world.

It adds that there are two working modes.

In Guest mode, the most common, the studio sends a link by email, WhatsApp or QR code. Accepting the link opens a welcome screen, and clicking on it registers the user on the operator’s waiting list, to go on air at the right time.

Reporter mode does not require an operator in the studio. “By tapping on the welcome screen, the user remains active in the air on the pre-assigned codec line or the one available at the station.”

How WJGO Recovered From a One-Two Punch

Radio World - Tue, 11/28/2023 - 11:54

A broadcast engineer hopes to go his or her entire career without having their transmission facilities wiped out by a disaster like a serious fire or a hurricane. 

Jason Horvath and his colleagues had to deal with both types of crises six weeks apart.

Horvath is corporate chief engineer and IT director of Renda Broadcasting Corp., which owns WJGO(FM) “Bob FM 102.9.” It is a Class C1 station with 96 kW ERP licensed to Tice, Fla., and one of four FM stations with transmitters at a site owned by American Tower in Fort Myers. 

WJGO shares an antenna combiner system there with Beasley Media stations WWCN and WJPT. The tower is also the home of Fort Myers Broadcasting station WTLQ(FM) and a translator for Relevant Radio.

On Aug. 18 of 2022, an electrical fire erupted in the transmitter building. 

“It damaged everything,” said Horvath. “Due to the fact that all the equipment was energized and running, by the time the fire company got there, the fire had traversed up into the wall, into the ceiling area, through the conduits and burned the insulation off of everything.”

All RF equipment at the site essentially was totaled, including Renda’s transmitters, combiners and processors. 

“The emergency personnel had to cut holes in the roof. There were two 20-ton air handlers that cycled everything, pulling all the smoke and soot through. And with the water and foam, it just destroyed everything.”

In the immediate aftermath, each broadcaster scrambled to get their stations back to something like normal operations. While Beasley switched to an auxiliary site a few miles inland, Renda was able to borrow an older Harris HPX20 transmitter from another one of its stations to get WJGO back on the air at half of its usual 48 kW TPO.

But that fill-in transmitter was also doomed. Because 41 days later a storm named Ian made landfall in the Fort Myers area as a Category 4 hurricane. Its 150 mph winds pushed water from the Gulf of Mexico across the low-lying landscape.

The transmitter site is less than a mile from the coast and about seven feet above sea level. The building was elevated another four feet off the ground. “But when you have a 16- or 18-foot storm surge,” Horvath said, “there’s nothing you can do.” 

Dozens of radio and TV stations in the region were knocked off the air by Ian, and WJGO was among them, victimized by the flood water. 

“There was no power. The building was blocked. There was debris everywhere. There was a barge blocking driveway access to the site,” Horvath said. 

“And once that hurricane happened, doing any construction, getting anything done in a reasonable amount of time, getting supplies in that region was impossible.”

Radio World has told the story elsewhere about Beasley’s own efforts to restore electrical power to its four FMs, one AM and five translators after the hurricane. But as bad as Ian was, Beasley wasn’t affected by the flooding at this tower site because it had removed all of its damaged gear after the fire. 

Not so Renda. WJGO stayed off the air for two weeks. Fuel supplies throughout the area were inconsistent. Broadcast sites and studios were difficult to access. Renda was eventually able to restore a 2 kW signal using a small temporary transmitter, and later went up to 10 kW with yet another loaner. But the station needed eight months to get back even to half-power. 

“Every piece of equipment, from generator transfer switches to transmitters, was delayed at some point due to supply chain issues,” Horvath said. Insurance processes and the limited availability of work crews also stretched the timetable out. And although the tower survived the hurricane, the ERI Axiom antenna that serves the Renda and Beasley stations had taken such a shaking that it needed to be retuned.

The new ERI combiner.

As of late 2023, all work now has been completed on a newly created iteration of the technical infrastructure that had existed before. The Renda and Beasley stations have a new three-station ERI combiner; Renda has put in a Nautel GV60 transmitter. One thing is for sure, says Horvath. “It’s hopefully a once-in-a-lifetime event.”

New Nautel transmitters in place for Renda.

Local Media Sellers Under Pressure To Drive Digital Ad ROI

Radio+Television Business Report - Tue, 11/28/2023 - 09:01

Local advertising sellers face growing expectations to sell more digital ad inventory and demonstrate higher performance on campaigns.

That’s a key conclusion of a new survey of 471 local-market digital advertising and marketing professionals released today by ad sales automation and workflow software company Frequence.

The report found that 72% of respondents felt recent changes to the digital advertising industry – like Apple’s recent AppTrackingTransparency feature – have led to a negative effect on their organization’s performance. More broadly, 70% feel like they struggle to keep up with all of the new strategies and technologies changing their industry, which include the rise of programmatic, streaming and attribution changes.

“Every day new advertisers enter the local market as barriers to entry fall and outcomes improve,” said Frequence CEO Tom Cheli. “Projections for future ad spend grow more optimistic by the day, and the excitement and growth have led to even greater expectations for performance.”

How important is technology support? Some 72% of respondents in the Frequence survey said they’d consider leaving their job for a competitor because of a lack of technology support. When asked what creates the most stress when working with clients, 33% cited gathering and analyzing campaign performance data as the biggest driver. Meanwhile, 29% cited pressure to sell more third-party ad inventory; 19% cited managing and adjusting campaigns in flight; and 18% cited determining an optimal mix of omnichannel campaign tactics or building a personalized proposal.

Among the other findings:

  • 37% say reporting ad / campaign performance or results is the most difficult part of their job; 27% say tracking in-campaign performance; 16% say drafting proposals and determining the right omnichannel strategies; 14% say adjusting strategies while campaigns are in flight; and 6% say coming up with and managing creative assets.

Additionally, 82% of respondents wish their organization provided them with more software to do their jobs.

“As the industry navigates this period of rapid change, one thing is clear: local-market media professionals need support to meet mounting challenges,” Cheli said. “Technological tools and greater automation can help immensely, and success awaits the companies that invest now to give their employees the tools and resources they need. Local-market advertising is a resilient, adaptive industry, and with the right strategies the future for media companies will remain bright.”

A Community Radio Upgrade Comes, With BE’s Help

Radio+Television Business Report - Tue, 11/28/2023 - 05:59

With 3,000 watts and a signal contour allowing it to serve three Southern Illinois cities, a noncommercial FM with a checkerboard schedule of programming has attracted an audience by being a true community radio offering.

Recently, the need for an FM transmitter upgrade arose for the station’s owner. It ultimately went with a product from a company based not far to the west, in Quincy, Ill.

WDBX-FM 91.1 in Carbondale, Ill., licensed to Heterodyne Broadcasting Co., selected a Elenos ETG3500 transmitter. Thus far, the station’s Operations Manager, James Helfrich, couldn’t be more pleased with the new equipment.

“When it was time to replace our aging transmitter, we shopped around quite a bit on medium power compact transmitters,” he says. With set-up of the new transmitter an easy task for WDBX, Helfrich says it brought a non-broadcast benefit that truly helped the station’s budget. “In the first summer of operation we experienced an average of 30% of more in energy saving from unit operation and association reduction in cooling cost.”

WDBX is pairing the Elenos ETG3500 with a new Inovonics 272 processor. As a result, Helfrich says, “Our signal is stronger and has never sounded so good.”

The Elenos ETG line offers circuit boards with a special coating, coupled with an aluminum chassis. This protects from corrosion. Redundant fans provide ample air flow for cool operations; a “lifeXtender” control algorithm keeps the transmitter operating at the highest safe power level even in the event of total fan failure.

“We are excited and pleased to help WDBX deliver its unique programing across Southern Illinois and thank them for trusting the Elenos Group with this important purchase,” BE President/COO Rich Redmond said. “We know the energy savings and the reliable operation that the ETG transmitters deliver will provide WDBX reduced operating costs and peace of mind for years to come.”

Elenos Group sales associate Ben Marth worked with WDBX with the acquisition of the new transmitter.

ATSC 3.0 Audio Services: The How and Why

Radio World - Mon, 11/27/2023 - 17:43

Liam Power is senior systems engineer, ONE Media. Skip Flenniken is VP/GM of Technology Business Development, Sinclair.

One of the most interesting applications of ATSC 3.0, the new global standard for broadcasting, has been its use not only for television services but also for pure audio (radio) services. 

ATSC 3.0 enables the use of IP (Internet Protocol) as a core part of the standard, allowing enormous flexibility in the potential applications of the specification. If you can send traffic over an internet link, you can also send it over 3.0. At the end of the day, it’s all just bits: video, audio, software, files, signals, and so on. 

As a result, we can deliver audio services through a remarkably efficient, far-reaching and modern system.

Over the past year, we have experimented with a variety of methods of encoding, transport and physical delivery in several markets across the country including Baltimore, Las Vegas, Nashville, Detroit and Washington. The paper “Audio Services Over ATSC 3.0: A Proof of Concept,” given at the NAB Broadcast Engineering & IT Conference, explores in detail the decision-making and testing that led us to the current system design. The key results are summarized here.

A diagram of the prototype radio system. Metadata and thumbnails are also delivered over the air, providing a comprehensive experience without the need for an internet connection. Encoding and transport

First, when it comes to encoding, we found xHE-AAC by Fraunhofer IIS to be the most efficient at the targeted bitrates while maintaining “Good” perceived quality, compared to AC-4, HE-AACv2, HE-AACv1 and AAC-LC. This allowed us to carry audio at 24 kbps for music services, and even less for talk radio. It also has broad compatibility across devices and operating systems, simplifying integration.

Making a choice regarding the IP transport mechanism was a more difficult decision, as the standard options within 3.0 are geared towards much larger data streams than those used for audio, resulting in significant overhead at low bitrates. 

We experimented with UFTP, MPEG TS, muxed MPEG TS, RTP and Pro-MPEG RTP, as well as MMT and ROUTE, which are standard within 3.0. In the end, our decision to use Pro-MPEG RTP was second only to raw RTP for low overhead, but it came with the key benefit of FEC and ease of integration on the receiver side. One other interesting activity that we have been monitoring is BBC R&D’s work with QUIC multicast, which shows great promise in efficient distribution.

While we could simply insert the data at this point, one item within the 3.0 spec we took advantage of was UserDefined signaling, which allows us broad flexibility by permitting any valid non-conflicting XML to be sent as part of the standard signaling bundle known as LLS, or Low-Level Signaling. We crafted our service listing to allow for dynamic channel listing, some basic metadata and the ability to hand off services as a vehicle moves between markets.

Distance drive tests in the Baltimore area. We were able to receive the signal out to the Delaware border, to 10 miles north of the Pennsylvania border, and down to Washington. Testing in the car

With signaling and IP in hand, we turned to the physical layer. There are nearly endless parameters that can be tweaked here, allowing us to adjust to any reception case. 

For this activity, we focused primarily on a vehicle traveling 75 mph down the highway and secondarily on surface streets and in urban canyons. There are multiple excellent pieces of software that allow us to estimate reception in these cases, which we used in combination with real-world experimentation to determine a configuration that would result in full coverage of our target market. 

In our Baltimore tests, we were able to receive the signal out to the Delaware border, to 10 miles north of the Pennsylvania border, and down to Washington. In Detroit, the signal made it into Lansing going west and north past Flint. 

In both cases, this outperformed comparable FM stations hosted from a similar location, crossing well into adjacent markets, and notably, taking up a fraction of the bandwidth used to send an equivalent FM channel over the air. To make the math simple, using 20% of a UHF television channel a station can offer one hundred (100) audio services.

These results have several interesting implications for the radio industry and its competitors. 

One recent development is the removal of AM tuners from vehicles, particularly EVs. Being primarily on the UHF spectrum and thus unaffected by the interference plaguing AM receivers, 3.0 provides a convenient “lifeboat” for AM stations to still have a presence in vehicles, the primary location for radio listening. Additionally, 3.0 delivers improved audio quality and reach over traditional AM radio. This, of course, relies on vehicles having ATSC 3.0 tuners in them, but we have reasons to be optimistic on that front. 

It also isn’t just AM that can benefit from the improved quality and reception. FM and satellite can see similar advantages, as it is very simple to tweak the encoding to meet the desired bitrate, rather than being locked into specific quality levels. ATSC 3.0 provides the advantages of digital radio without the quality loss.

In Detroit, the signal made it into Lansing going west and north past Flint. The maps show sufficient overlap with adjacent markets to allow for signal handoff between towers. Flexible and efficient

The efficiency of ATSC 3.0 for linear content creates the opportunity to offload expensive internet and satellite delivery onto 3.0, primarily for the satellite and streaming companies, but also for those radio stations that provide online streams of their stations. 

Because of the IP nature of 3.0, it can easily transmit audio feeds and failover to the internet in the event of signal loss or market change. For large-scale providers, it offers the opportunity to bring their distribution costs more in line with those of radio stations, as they can take their most-listened linear streams and dynamically send them over 3.0 as listenership changes throughout the day.

Last, an area being actively explored is the integration of digital radio standards directly into 3.0. We have performed experiments with multiple standards thanks to the cooperation of such entities as Fraunhofer IIS and Xperi/DTS and found the burden of integration to be low. This presents a straightforward way to utilize 3.0 with existing receiver systems by carrying the digital radio data over 3.0 and passing it to the digital radio receiver. Imagine an RF-agnostic delivery method, where a signal could be received over AM, FM, ATSC 3.0 or the internet and presented in the same way to the end user. This would ensure the broadest availability at the lowest distribution cost.

In short, ATSC 3.0 is an immensely flexible and efficient standard, creating significant business opportunities for audio services delivered over broadcast.
