.radio Internet Domain Grows as New Stations Launch Approximately 2,500 domains registered in the first year of new EBU-operated domain BY WILL JACK SON GENEVA — Nearly 2,500 .radio domains have been registered since the launch of the new Top Level Domain in August 2017. ICANN, which manages internet domain names and IP addresses, granted the new .radio TLD in July 2016. It can be used for web and email addresses, and is managed by the European Broadcasting Union with the support of other world broadcasting unions. The .radio domain is reserved for the

exclusive use of the radio sector, broadcasters, internet radio stations, people working in radio, companies supplying goods and services to the industry, along with radio amateurs.


Prices for .radio domains depend on the registrar, however for individuals, a .radio domain is likely to cost around €25 (US$30), or for companies, around €220 (US$255). To prevent “cyber-squatting,” applications for domains are checked by the EBU .radio team to ensure they meet

the required criteria. Alain Artero, who manages the domain for the EBU, found that a significant number of initial registrations during the launch period were “defensive,” (continued on page 5)

in order to reserve particular names. Now however, he believes most registrations are linked to new projects such as internet radio services, new broadcast radio stations, radio-related thematic websites or are linked to a change of main domain. The majority of the new .radio registrations have come from North America and Europe. Artero says: “We’re now beginning a campaign to develop the awareness of .radio and its adoption in the other parts of the world, especially in Africa and Asia.” Artero believes that some radio stations are reluctant to change their wellknown domains, perhaps because of a lack of knowledge of the migration process. “A simple web redirection from the old domain to the new .radio domain makes it all transparent to the users,” he explained. “They can keep using their old internet addresses — old URLs — or the new, with the .radio domain, and see the right content in all cases without a glitch. If registrants need support in this respect, we are happy to advise for free.” EBU research has identified a number of factors influencing a decision to change a current domain name. The primary reason is to add meaning to a domain name through the .radio extension. Other reasons include to follow a new trend or be a pioneer, to simplify or shorten a domain, or to have a more modern and fun name. Artero says he’s also seeing radio stations taking advantage of the new domain to develop a profile on social media, citing the new

The owner and founder of Bigtime. radio, Charles Cawood, comes from a music industry background, as an artist, label and publisher — and is now taking on traditional broadcast radio with his business partner, Ronnie Sparks, who shares his interest in helping artists and listeners with “feel-good” music.

and he was very helpful in guiding what I needed to do. I soon registered, then I built the website, and set up the radio platform from which we now run two stations. We now have over 12 million touch points running through our social channels, and we’re growing with tens of thousands of people visiting our websites.” Cawood says the .radio domain is a

key part of this success. “We feel that for our international brand, .radio is perfectly aligned to what radio is, and should always be. We are more than just radio stations, and offer extended services to artists within our community. Our aim and passion is to help talented artists get aired and heard and also get paid their royalties. We have a tough model, but we want to do all we can to help good music to be heard worldwide. With nearly 3 billion new internet users in developing countries coming online via mobile or new internet networks, it gives bigtime. radio specifically an edge in the world.” “As a radio owner, we are building a group of companies that want to help the art and music world,” says Cawood. “We have plans for TV shows and many more exciting and new things with technology that we are looking into. Through our radio channels, we have seen artists get signed with labels and this brings joy to us.” Meanwhile, Artero is also looking to a bright future. “We are now developing new services reserved to .radio registrants, which we hope will bring interesting added value to the .radio domain,” he explains. “One of them is intended to help registrants to use their domain. It targets individuals and small stations who don’t have time and/or skills to implement their web presence.”


“Almost a year later we decided to work collectively, and formed a group of companies under BigTime Radio,” said Cawood. “We had a discussion about domains, and then we found .radio. I called Alain

◗MARKETPLACE DEVA DB45: Broadcast equipment manufacturer DEVA Broadcast says its new DB45 is an essential tool for the reliable monitoring of FM signals. With a DSP-based core and a compact, practical design, the system promises accurate parameter measurement, including the RF level, MPX deviation, MPX power, left and right audio levels, RDS, and pilot injection levels.

Bionic in every sense.

The smartest audience engagement and content production radio has ever seen.

Upon demodulation of the FM signal, the SDR FM tuner digitizes the RF signal and all signal processing is achieved through algorithm calculations. Thanks to the precision of this tool’s digital filters, says DEVA, the FM multiplex signal’s components can be accurately and repeatedly reproduced from one device to another. This means, for example, that the same signal applied to two devices would give the same result. The DB45 also features an “easy-to-use” web interface, a built-in audio streamer, which lets users listen to and record audio from any station, and TCP/IP (GSM connectivity is optional) for remote monitoring.

routing system and digital radio broadcast consoles back then were heavily customized, based on our technical requirements and built by a reputable German manufacturer to be very powerful, highly configurable and very reliable. By 2006, Astro Radio required much more functionality, which would simplify studio workflows and give on-air talent more time and flexibility to focus on delivering compelling content both on-air and online. We had to rethink how a studio broadcast console should be in a rapidly evolving commercial FM radio industry. We took the best features of our first console, analyzed common operator mistakes and gathered improvement suggestions. We condensed all of this invaluable data into a comprehensive document as our mandate to German broadcast console manufacturer Lawo AG for a brandnew broadcast console. Lawo’s answer was the zirkon 2s modular broadcast console. The zirkon 2s was truly simplicity, personified in both form and function for our on-air talents. For example, a press of a macro button could simultaneously record telephone calls, edit talk sets and run an outside broadcast.


In 2015, Astro Radio picked up on the touchscreen technology trend and leveraged on in-house expertise to brainstorm on advanced broadcast consoles for a transforming radio industry. Building on the success of the NewsRoom Lawo

Virtual Console, which we effectively deployed in 2016, Astro Radio embarked on a third generation of radio consoles for its new studios in Kuala Lumpur. In mid-2016, we began sketching out plans for a virtual console for Astro Radio, which would shift the paradigm on the industry perception of a broadcast console. We wanted to radically reimagine what an on-air studio would look like, including what to fit inside the studio and what to leave out. The studio environment would impact how the on-air talent uses the technology inside the studio with the new virtual console as its focal point.

The virtual console needs to be very simple and intuitive to use for first-time users. The virtual console would respond to expectations of our new breed of onair talent. Today’s radio on-air talent in Malaysia is already well-known online personalities with huge fan bases and following. Our radio stations leverage on these talents’ star-power to both maintain and grow radio listenership — on FM, streaming online and on popular social media platforms. Content managers expect new on-air talents to quickly build momentum and get up to speed. They are expected to

BUILDING A FUTURE-PROOF FACILITY In 2017, Astro Radio acquired two new radio stations and needed space for new on-air studios, producer workstations and equipment room. However, our broadcast facility already had 13 on-air studios, seven news studios, three voice-booths, eight audio production studios and edit suites, six equipment rooms and three equipment storerooms. So, our first task was to secure space to build our new studios. We share our headquarters with many business units and divisions. Astro Radio shares a floor with our group’s Astro-Finance department. They had space we needed for our new studios. They needed space to run their meetings. Ultimately, we compromised and came to a mutually beneficial arrangement. We would take their meeting rooms, which were located just behind our Master Control Room. In return, we would share our current and future meeting rooms with them. We engaged the services of an interior designer that understood our design ethos, criteria and expectations. Our mandate to the ID was to create designs for three on-air studios, which were minimalistic, stunning, functional and meet Noise Criteria Rating 20. We wanted designs, which would inspire our on-air talents to deliver compelling content on-air and on-line for today’s radio. We also wanted designs that were forward-looking in anticipation of how

deliver “catchy” talk sets on-air, produce compelling video content online and engage with listeners on social media regularly during their shifts — everyday. There is very little time for training or to familiarize themselves with the technology inside the on-air studio. The virtual console therefore needs to be very simple and intuitive to use for first-time users. It should also be quick and responsive to execute commands, highly configurable and securely “idiot-proof.” The virtual console “platform” allowed for a faster software development cycle. We were able to develop new features

radio could evolve in the next five to 10 years. The studios would be devoid of equipment racks, tableclutter and unsightly cables. We ensured our designs also addressed building health and safety requirements. These included concealed cabling-trunking and access holes for all cabling inside the studios, equipment room and in-between. We decided the studios would have standingheight tables with adjustable high-chairs. We also identified the best combination of color and materials for the fabric wall-panel, carpet, table, wall cornice and skirtings, ceiling, joinery, furniture and fittings and lighting. We went through over 50 drawing versions before settling on the confirmed designs. Our new studios are box-within-a-box designs whereby each studio is placed on its own isolated floor platform, to ensure vibrations would not carry between the rooms. The wall structures use a multilayered system of 16 mm and 20 mm cement sheets and vacuum buffers. The glass fittings used to create a transparent effect were vacuum packed. Special acoustic materials were used to ensure sound integrity of the space. The end-results speak for themselves. Our content managers and on-air talents are so blown-away by how the studios look, we’ve received nothing but praises and smiles all around. — Jude Isa Dawson and Bala Murali Subramaney

and functionality both for “default” and user-specific “snapshots.” We could easily customize the console layout or ‘skins’, redesign and resize fader and button shapes and colors, incorporate macros and GPIO signaling. This flexibility gave us the freedom to explore new possibilities in console design paradigm. For example, we added more channel faders per screen and moved monitoring level-controls to a pop-up screen.


We spent close to six months evaluating 15 touchscreen products available in the market — both consumer and industrial-grade devices ranging from off-the-shelf tablets, point of sales (POS) machines and built-for-factory devices. We also explored consumer tablet devices but quickly dropped that idea because these devices are neither robust enough for 24/7 operation, nor adequately secure to connect safely to the studio router via Wi-Fi or Bluetooth. We refined our selection criteria to device dimensions, screen size, display area, fanless cooling, wide viewing angle, anti-glare screen with high brightness, capacitive touch-enabled and suitability for 24/7 operation. Soon after, we ran into our biggest roadblock. Most touchscreens have a limited viewing angle and had to be tilted at an angle to be clearly seen. However, the virtual console had to be flush-mount into the studio table. The deciding factor was screen brightness. The brightness of most touchscreens is 500 nits or less. For our virtual console, a brightness of greater than 500 nits overcame the viewing angle issue. We finally settled with a built-for-factory touchscreen device for the virtual console.

There are many questions that arise from the choice of interface. For example, what if the touchscreen hangs, fails or is damaged? The answer lies with the Vistool-PC. In addition to the standard features, it also shows all the virtual modules of both touchscreens. The user can control all channels, faders and buttons on the touchscreen from the VistoolPC interface. Similarly, if a touchscreen fails, the on-air talent can also control the console via the Vistool-PC. This gives the engineer time to replace the faulty touchscreen with a spare unit. In addition, it is possible to clean dirty touchscreens in an on-air studio by simply disconnecting the USB control cable to the touchscreen. One advantage of the virtual console is cost-savings on physical consoles. There is no longer a need to stock-up on expensive console spare parts and accessories. The virtual console is also aesthetically more pleasing to the eyes, and gentle on the hands. Astro Radio took a huge risk by implementing fully touchscreen virtual consoles in our live radio broadcast studios and from the happy faces of our

◗NEWSWATCH WECODEC RELEASES REPORT ON JOHANNESBURG DRM+ TRIAL Digital Radio Mondiale has announced that Westbury Community Development Centre (WECODEC) has presented the results of its DRM+ trial that took place in Johannesburg from March to October 2017 to Independent Communications Authority of South Africa (ICASA). The publication of the document coincides with ICASA’s open hearings taking place now in South Africa’s largest city and details the DRM test, which WECODEC, an organization serving disadvantaged communities around Westbury, Sophiatown and near Johannesburg, carried out with its community radio station Kofifi FM 97.2. During the DRM+ trial, Kofifi FM broadcast BBC and local content. The document concludes that the DRM broadcast did not interfere with the analog FM transmission of neighboring stations. “The audio decoding was possible at almost all predicted areas showing a similar of better behavior than the FM audio reception or the analog signal transmitted from the same site. The power consumption was also much lower than in FM,” the report stated. It also demonstrated that despite Johannesburg’s full FM Band, DRM was able to fit between two FM stations where a gap existed, thus requiring no extra spectrum space to provide additional content. For the trial, which was supported by the BBC and other DRM members, ICASA granted WECODEC an eight-month license. The station used a complete transmission system, which included an RFmondial ContentServer, A/D interface and VHF DRM modulator as well as a Nautel exciter/transmitter and a 2.5 W power amplifier.

GATESAIR SIGNS FM DEAL IN BULGARIA Bulgaria’s BTC has purchased GatesAir Flexiva FAX 10 kW transmitters for eight high-power FM radio sites through New Tek, GatesAir’s local channel partner. Specifically, says the firm, the transmitters will be delivered in redundant N+1 configurations and include Direct Drive designs to simplify RF designs and enhance efficiency. Deliveries will take place across three phases — the first delivery, anticipated in the next several months, will cover the two main network sites. GatesAir recently also installed its Maxiva DVB-T and DVB-T2 transmitters at BTC television facilities. “Low power consumption and reduced operational costs associated with GatesAir transmitters were cited as key factors in the decision,” said the company in a press release.

Merlin Codecs Provide STL Magic for Mediacorp Tieline solutions shine in Singapore broadcaster’s new facilities


Engineering Director Telesto Broadcast Solutions SINGAPORE — Mediacorp is a Singapore media com-

pany that pioneered the development of Singapore’s broadcasting industry. In 2016, Mediacorp relocated to a new office in Mediapolis@one-north, Singapore’s first digital media hub. The Mediacorp Campus is the anchor tenant at the 19-hectare media hub and features two large studios, post-production suites, plus news gathering and broadcasting facilities. Mediacorp broadcasts 12 stereo radio channels in Singapore. As a result, they required a new and reliable solution for delivering program content from Mediapolis to their Bukit Batok transmitter site in western Singapore. Telesto Broadcast Solutions Pte Ltd, a system integrator based in Singapore, participated in Mediacorp’s tender process for 56 audio codecs in 2014. Telesto has a substantial track record of successfully implementing similar innovative transmitter link systems in Brunei and throughout Australasia. We recommended Tieline codec solutions to Mediacorp and were subsequently awarded the tender in 2015.


In parallel with the construction of new premises at Mediapolis, Mediacorp’s engineers had the opportunity to review and implement innovative workflows, systems and equipment for their new studios prior to moving there in 2016. IP was the primary and backup transport of choice and Telesto Broadcast Solutions worked closely with Mediacorp to design a tailored solution encompassing Tieline’s TLR5200M Merlin codec, together with the Tieline CMS (Codec Management System). Mediacorp had stringent IP redundancy requirements and Telesto outlined the salient features of Tieline’s Merlin codecs in line with operational requirements. Stereo STL data is transported over separate fiber and microwave links to maximize IP packet redundancy and minimize service interruption. Twenty-four Merlin codecs are used to transmit and receive 16-bit linear PCM audio at 48 kHz sampling over the primary fiber links. Twenty-four backup Merlins encode and decode with 24-bit aptX Enhanced encoding at 48 kHz sampling and these act as a hot standby for each primary connection. This means that all components can be exchanged

delivery and installation of all hardware. All codecs were thoroughly bench tested, configured and loaded with the latest firmware. This preparatory work led to a seamlessly fast install and commissioning when building infrastructure was completed. Tieline’s Codec Management System is installed and used to control and configure all codecs installed and offers network management tools for remote control, monitoring and configuration. It allows Mediacorp to create and manage primary and backup connections, view audio PPMs and IP statistics to maintain mission critical connections. You can also adjust individual codec settings like algorithms, jitter buffers and forward error correction. The system also offers detailed alarm and fault detection information. After installation and final commissioning, Tieline’s Charlie Gawley provided training to Mediacorp’s engineers. He commented that he was “impressed with the engineers’ knowledge of the product and its capabilities,” which was testament to the meticulous groundwork and preparation by both Telesto and Mediacorp. Overall the project has been a huge success and has been operating flawlessly since handover in 2016. Telesto Broadcast Solutions has provided widespread

and replaced at any time and there is no common single point of failure in either the main or backup hardware configurations. Four codecs at each end are also configured with backup programs so they can be swapped out with any of the other 48 codecs installed. Using common technology for both the main and backup systems has reduced training and configuration requirements. It also ensures there is a minimal requirement for holding spare parts. Tieline’s SmartStream PLUS technology delivers seamless and silent switching of IP data packets sent across diverse LAN/ WAN networks. This was a key Mediacorp requirement for the main and backup links. By integrating dual-redundant downstream switches, the possible failure of any hardware component is covered by switching to the backup path. This applies to the codecs, the network switch or the fibre/microwave link. Both physical ports on the codec are set up with multiple IP connections that effectively build a mesh of connections between the source and the destination. It was not sufficient to treat the fiber link and the microwave link as the only main and backup connection, it was also necessary to look at the way the audio is transported to each physical interconnection.


For the studio-to-transmitter links, Telesto Project Manager, Loan Hon Pheng, liaised with Mediacorp and their overarching systems integrator to ensure timely

advice and support to broadcasters throughout the Asian region. The company has a relationship with Tieline that goes back over 10 years and the company has sold and supported the entire range of Tieline audio codecs for both Outside Broadcast and studio-to-transmitter link applications. Factory support is delivered within the region and clients can also call upon the full assistance of the excellent Tieline support team at the factory in Perth, Western Australia.

internet-based approach. We purchased Barix equipment for our STL encoder and decoder based on a recommendation from another community radio station. They were rea-

sonably priced and straightforward to operate, so we deployed an Instreamer for our studio and an Exstreamer at the transmitter site. The encoder and decoder worked great right away, but I can’t

so using temporal redundancy on a single network link, and/or by sending a redundant stream over a second path. With just one connection, we chose the former approach. A Redundix unit at the studio sends the 128 kbps MP3encoded RTP stream from our Instreamer twice, once with a time delay; the second Redundix at our transmitter effectively merges the two into a single “healed” Barix Exstreamer, small box at lower right, and Redundix, upper left, at the Vectis Radio transmitter site.

the Isle of Wight off the south coast of England, Vectis Radio delivers news, weather forecasts and community programming about the local economy and culture. Launched as an internet-only radio station in 2009, we went live with our first FM broadcast on 104.6 MHz in November 2017. We faced a number of challenges in linking our studio to our 25 W transmitter, which is located basically in the middle of nowhere. The transmitter site is a rented space at a golf club at the top of a hill — a rather unusual place for a golf course, I’ll say! We could not use a direct microwave link, as the studio is almost at sea level, and part of the hill is in the way. Dedicated private circuits were cost-prohibitive, so we chose an say the same for the internet connectivity between them. The internet service provider we use at the studio is reliable but could not provide a high-speed connection at the transmitter site, as it’s so far from any main communications highways. The local ISP near the transmission site put in a short microwave link to the transmitter, but like any such link, it is subject to issues like packet loss and rain fade. Those turned out to cause a lot of headaches for us.


Our on-air signal has suffered from sporadic, unpredictable audio glitches. Working with Barix support and Andrew Nordbruch, the managing director of local IT consultancy Wight Computers Ltd., we identified the cause of the glitches as significant, irregular packet loss on our internet link. The packet loss varies considerably for no good reason. Weather does play a factor, as we get more packet loss when it’s very windy and rainy, but we’ll sometimes experience a great amount of loss even in clear conditions. The problem was so erratic that the ISPs were unable to resolve it for us. Barix offered to let us test their new Redundix product, and we jumped at the opportunity. Redundix is designed to avoid such audible glitches by repairing lost RTP packets in the stream. It can do

stream. Working together, Andrew and I determined the optimal time delay to be 800 ms. That introduces a bit of latency, but we can live with it to give us stable, high-quality delivery. The Redundix units work well and clean up the transmission considerably. Our packet loss is severe enough that we still get glitches on occasion, but Redundix has eliminated at least 90 percent of them, and the glitches are significantly shorter as well — to the point that most listeners won’t even detect them. If we have the money in the future, we may add an ADSL link to the transmitter site as a backup and enable Redundix’s pathbased redundancy as well, which I expect would eliminate the few tiny remaining glitches. The Redundix interface provides a lot of valuable information about our network connectivity, and I love that I can access all of the Barix boxes — the Instreamer, Exstreamer and both Redundix units — through web-based interfaces. As the sole technical guy for the whole station, being able to troubleshoot any issues remotely from home is convenient. But the Redundix units themselves have helped us overcome our biggest issue, minimizing the impact of network packet loss and thus improving our audio quality for our listeners.

AGM Chooses Wheatstone for Bakersfield WheatNet gives flexibility to operations while also interfacing with other Wheatstone equipment


Corporate Director of Engineering American General Media BAKERSFIELD, C alifornia — I was out of town and enjoying a mini vacation from my duties as American General Media’s corporate engineer when I got the call. Two politicians had shown up unexpectedly at our studios in Bakersfield at the same time, and staff wanted to do a “town hall meeting/ mini debate.” The main studio was too small, and they needed to move things to our larger performance studio down the hall. I asked when they wanted to make the switch, and they said about six minutes

after the news. No problem. I pulled out my iPad, VPNed into our WheatNet-IP network server and, using the system’s Navigator software, I set up a cross point between the performance studio and the main studio about 300 feet away. I then mapped each mic to its own console channel and routed talkback from the studio to the host headphones. I was able to do this faster than they could have walked down the hallway and done a mic check.


This sort of flexibility is why I decided to go with WheatNet-IP audio networking after a fire destroyed American General Media’s Bakersfield studios almost two years ago. The fire started with faulty electrical in the TOC, melting the servers there. The smoke

damage was so extensive, the studio facility for all six of AGM’s stations in Bakersfield, California, was a total loss. AGM, which has stations throughout California, New Mexico and Colorado, had WheatNet-IP in the Albuquerque facility so I was more than familiar with the system. For Bakersfield, I did look at other systems but decided for certain to go with WheatNet-IP when I ran across a WheatNet-IP system installed by a European vendor to showcase their on-air lights. It says something when a vendor buys a product to make their product look good. I purchased IP-12 consoles for the six on-air studios, each with talk studios and a shared central mixing studio with glass all around, plus a large production studio and a performance studio complete with a stage and lighting. The entire facility was outfitted with Wheatstone’s modular QuickLine furniture and networked together through the WheatNet-IP audio network. There’s not a soundcard or relay box in sight. Through IP audio drivers, I was able to tie in critical pieces of audio gear. For example, VoxPro digital audio recorders/editors are in every on-air studio, networked through WheatNet-IP for intense show productions requiring shared files and editing functions.


In addition, I was able to add video to our webstreams using camera automation tied into WheatNet-IP in each studio, and enhance shows and sportscasts with graphics from its new digital content department complete with greenroom. It’s all controlled and managed through one IP audio network platform

accessible from phones or laptops. As expected, the installation was fairly stress-free. It took about 10 minutes per studio to install the QuickLine furniture, which is why they call it QuickLine. This is Wheatstone furniture that comes in five modular components that are reversible, so you can get up to 32 functional configurations. Hooking up the WheatNet-IP system was straightforward. They’re not kidding when they call it plug-and-play. I simply plugged the Cat-6 cable into a Blade (I/O unit) and it self-installed into the network. This was certainly a lot easier than most of the studio projects I have managed in the past — and I’ve been involved in 900 studio projects in my career as a broadcast engineer. I can recall the enormous amount of time and engineering spent on tracing, stripping and punching down wire and making up connectors. By the time you add in time and labor, plus the punch down tools, shrink tubes, external relays and matchboxes, it can easily cost four times as much to do a punchblock routing system as an AoIP system. In the case of WheatNet-IP, I just put the Blade in a rack, got the premade XLR cables sitting on the bench and plugged it in. Just about everything is done using software; and by the way, we ordered all the connectors through Amazon, so it all came right to our door. The hardest part was ripping out the copper wiring that had been installed for the punchblock routing system used back in the day.

BRIC-Link Leaps Over Mountains for KSUT IP codec reliably handles STL duty for multiple transmitters


Independent Engineer

IGNACIO, Colorado — KSUT(FM)

is a public broadcasting organization that serves the Four Corners area in the western United States, with studios and offices on the Southern Ute Indian Reservation. As an independent engineer, I recommend equipment, help with configuration and troubleshoot any technical problems that may arise.


KSUT produces two broadcast streams from their headquarters in Ignacio, Colo. The Four Corners/NPR programming is delivered to five transmitter sites around the Four Corners, while Southern Ute Tribal Radio programming is delivered to two transmitter sites. About six years ago, KSUT installed the first BRIC-Link IP codec as an STL for the tribal programming service. I

liked the BRIC-Link’s reliability and AAC compression, so we went on to add five more BRIC-Link pairs as primary STLs. For years, KSUT ran a Comrex ISDN unit as an STL to a remote transmitter site. The Comrex units were so reliable

that after a lightning strike, which blew out the main output, it continued to work for several more years. When we started having interference problems with our radio STLs, KSUT began using Comrex BRIC-Links to bypass the interference issues.

One of the reasons I chose Comrex equipment is the great support. I always read the manual, but it’s helpful to be able to call and speak with a person who has a wealth of knowledge about our equipment. The Comrex support team has been especially helpful in configuring our BRIC-Link infrastructure. We have some challenging connections — for example, there’s a 3,000+-meter mountain between our studio and one of our transmitter sites. The internet pathway is punctuated with microwave hops. Despite the geographical challenges, our BRIC-Links reliably run at 128 kbps and I rarely have to do anything to the connection or the equipment. The BRICLinks have a GUI interface that allows troubleshooting from any computer. KSUT has been very happy with the Comrex products and support. The BRIC-Links have been reliable and so far, we have had no major failures. Because of the dependability and excellent support from Comrex, I would recommend a BRIC-Link system to anyone.

AoIP Evolution With GatesAir at Washington’s WAMU Intraplex IP Link codecs and Dynamic Stream Splicing technology solidify signal chain


Assistant Director of Engineering WAMU(FM) WASHINGTON, D.C. — The Ameri-

can University-owned WAMU(FM) has been the primary NPR member station for the Washington area since the birth of NPR, broadcasting a mix of a national content, hourly NPR news and locallyproduced public affairs programs. In recent years, WAMU has transitioned almost exclusively to IP for audio production, contribution, and distribution. This includes our AoIP studio plant, studio-to-transmitter links, and backup links to NPR’s Network Operations Centers. We rely heavily on GatesAir’s Intraplex IP Link codecs to ensure uninterrupted audio delivery. Intraplex IP Link codecs provide audio connectivity to all of our transmitter facilities. Our IP Link codecs are the primary STL paths to our auxiliary transmitter site, collocated with WETA(FM) in Arlington, Va., as well as to our satellite station WRAU(FM) located in Ocean City, Md. Both sites are fed via diverse public internet links. Dropped packets are inevitable even with the most stable internet connections, but Intraplex IP Link codecs have a feature called Dynamic Stream Splicing, which

virtually eliminates audio dropouts. Dynamic Stream Splicing works by combining packets from multiple streams to reconstruct any missed audio frames. This can be done over separate internet connections, or even a single internet connection by delaying one stream by 50-100 ms and adding forward error correction (another built-in feature of the Intraplex IP Link codecs). We also use Dynamic Stream Splicing on the return path from WRAU so we know that what we hear at the station is what listeners hear over the air 150 miles away. We’ve been blown away at how well this feature works, and it’s extremely rare that the Intraplex IP Link cannot deliver flawless audio. Another great feature of the Intraplex IP Link is the ability to set up multiple failover audio sources. These can be additional RTP streams (from a different source Intraplex IP Link device), AAC or MP3 web streams from a CDN, or even a USB Drive preloaded with audio. This flexibility enables us to deliver continuous audio to listeners even in the event of audio or total primary stream loss. Audio from our Intraplex IP codecs is delivered to AES switching networks and ultimately the audio processors located at each transmitter site. For our main site, which maintains a native Livewire path as its primary connection, the Intraplex IP provides a redundant backup via diverse links in case of interruption to the leased fiber link that

conveys our Livewire connection. It’s a very robust setup. We also convey our nationally distributed program, “1A,” to NPR’s primary NOC in Washington and backup NOC in Saint Paul, Minn. While we still rely on legacy T1 technology to get us across town to NPR, we are working to transition to a new standard that would utilize

◗TECHUPDATE AETA µSCOOP SIMPLIFIES STL TASKS LES PLESSIS ROBINSON, France — AETA’s µScoop full-duplex IP audio codec, available with analog or digital input/outputs, is designed to utilize IP connections over wired IP networks. Two types of packet duplication functions ensure transmission. This, says AETA, makes it possible to improve the resistance to packet losses, thus increasing connection reliability. The auto redial feature lets users configure the number of redial attempts in case of a connection loss along with a waiting time before each attempt. If the link is dropped, the codec relaunches the call and sets the link up again. This feature is also effective in the case of a power failure, with µScoop recalling the remote unit as soon as it restarts. Thanks to the new AETA Remote Access feature, µScoop can now be controlled remotely and in real time via the internet. The system relies on using a remote access server as an intermediary between the codec and the control device. It allows the user to access the embedded html servers of the codec, and thus to control all the settings and parameters of the codec in real time. In addition, µScoop features multicast transmission; Ethernet remote control from its embedded HTML server; configurable status and control relays (GPIO) that inform users when the remote µScoop is synchronized; a choice of encoding algorithms including Opus and MPEG AAC; and SIP or direct RTP modes.

the Intraplex IP Link over the public internet at 256 kbps AAC to reach both the primary and backup NPR NOCs, which makes the Dynamic Stream Splicing application that much more valuable. At each NOC, IP Link codecs receive the signal and provide the same stream reconstruction service as we use at our transmitter sites. This is a fairly straightforward operation, though once again the reliability and stability of the IP Link has proven exceptionally valuable. If the main NOC in Washington were to go down, the backup NOC in Minnesota picks up the stream to ensure an uninterrupted national broadcast. Once decoded, the signals are then re-encoded in IP Link devices for national satellite delivery. Our most recent use of the IP Link codecs involves reimagining our main program channel streaming service. We’ve begun experimenting with the IP Link hardware to eventually replace Microsoft Windows-based stream encoders to deliver the audio to StreamGuys, our CDN and streaming media service provider. Like many stations, we were often faced with the typical performance glitches that come with computer misbehavior. We believe that moving to dedicated hardware for audio encoding with the IP Link 100 will eliminate the shortcomings of a computer-based encoder. (continued on page 29)

Telos Has the Right Codec for the Job Z/IP ONE comes through in the clutch at Rhema Central Coast


Technical Operations Manager Hope Media Ltd. SYDNEY — I’ve been with Hope Media Ltd. for 14 years as technical operations manager; during that time I think I’ve seen it all, or at least most everything. Hope Media is a not-for-profit organization that runs Hope 103.2 on FM and Inspire Digital on DAB+ in Sydney. As one of the largest nonprofit community radio stations in Australia and due in large part to the resources that it has at its disposal, one of Hope Media’s missions is to foster, encourage and provide technical assistance to many smaller stations. These stations are located all over Australia and attention is given specially to rural areas, to help improve their content, fundraising and sponsorship. As a part of this ongoing mission, Hope Media loans me, generally at no charge, to stations in the community sector to help them with various technical projects. Recently one of these projects brought me to 94.9 FM Rhema Central Coast. It’s situated about 1.5 hours drive north of Sydney in Erina, and has a population somewhere in the neighborhood of 300,000. A couple of years ago they had to move transmission sites due to the land being reclaimed where their tower stood. Unfortunately, their existing 850 MHz STL wouldn’t work with the new

that they were suffering from interference at times with the 5.8 GHz link. So an alternate backup path was needed in order to achieve the stable signal that they desired. We tried 4G in the short term, but data plans would be prohibitive for the station in the long

transmitter site, and there weren’t any extra STL frequencies available. They installed a two-hop 5.8 GHz Ubiquiti link — the first hop is 8 kilometers/5 miles and the second is 3 kilometers/2 miles. It’s a small Axia Livewire facility. When I was brought onto this project I recommended running Livewire over the Ubiquiti link and installing their Omnia One processor at the transmitter site. This was reasonably successful, except

term. The transmitter site was hard to get an internet connection to. Like most transmitter sites it was a bit remote, but we eventually were able to get an ADSL connection installed with limited bandwidth and differing amounts of latency. Due to the station having limited funds, we tried multiple cheaper codecs over nine months, but unfortunately due to the ADSL conditions, it proved difficult and we were not getting the results that they needed. Fortunately, the station had

applied for a local government grant for codecs, and they were awarded it. Because of the ADSL conditions, I recommended Telos Z/IP One IP codec, which I have used extensively for backup paths and program distribution with Hope Media. The Z/IP Ones are great because of the Agile Connection Technology (ACT). It adapts to the connection’s conditions, you can set a minimum and maximum bitrate and also a minimum and maximum buffer. It will

try to use the highest quality bitrate and lowest buffer, but if packets start dropping it will increase the buffer or reduce bitrate, all on the fly. Since installing, the Rhema Central Coast connection has been rock-solid, running at AAC 320 kbps without any dropouts, and they couldn’t be happier.

◗TECHUPDATE DIGIGRAM IQOYA *X/LINK OFFERS FLEXIBLE OPERATION MONTBONNOT, France — The Iqoya *X/Link from Digigram is a 1U rack audio codec for the delivery of one or several audio programs over IP networks. The unit can be used in legacy analog and AES/EBU audio infrastructures, as well as in full-IP infrastructures, thanks to the support of Livewire, AES67 and Ravenna technologies. Using Digigram’s FluidIP technology, Iqoya *X/ Link provides for the transport of audio content over managed and unmanaged networks and for continuity of audio service on transmitter sites. According to the company, unique features include its four RJ-45 network ports, allowing for the integration into full IP infrastructures (full separation of IP traffic: AES67/Ravenna, dual streaming on WAN, control). The multi-encoding and multiprotocol streaming lets users stream a radio program

simultaneously to transmitter sites, DVB multiplexers — MPEG-TS/IP, web radio CDNs — Icecast/Shoutcast and other studios. The system can support up to 16 I/O channels (four analog I/O channels, four digital I/O channels on AES/EBU, and AES67/Ravenna I/O channels) and has a full AES/EBU transparent transport through PTP or external 10 MHz synchronization. Iqoya *X/Link is based on a lowconsumption, fanless dedicated hardware platform powered by two redundant power supply units. It features four analog audio I/Os and two stereo AES/EBU I/Os, and supports synchronous AoIP I/Os (Livewire, AES67, Ravenna). The unit supports one to eight stereo I/Os, and allows for multi-format and multi-protocol encoding and streaming of each audio source. The four

network ports allow for the separation of IP traffic: control and monitoring, redundant dual streaming through two network paths, and synchronous AoIP (Livewire, AES67, Ravenna). The Iqoya X/Link range also includes the X/LinkLE, X/Link-Dual and X/Link-AES67. For information, contact Digigram in France at +33-4-76-52-47-47 or visit

◗TECHUPDATE AVT’S MAGIC ACIP3 2M SUPPORTS STL APPLICATIONS NÜRNBERG, Germany — AVT Audio Video Technologies GmbH has introduced ModNet, a DSP-based hardware management platform for use with Magic ACip3 (2M) audio codecs and designed for STL applications. ModNet can be equipped with one E1 (2 Mbps) interface and/or three independent Ethernet interfaces, which can be used for the main audio signal distribution, for backup and also for control and monitoring. With the standard version, one stereo ISO/MPEG Layer 2 audio codec is available. With the optional twocodec upgrade two independent stereo audio signals can be transmitted with one system. If low latency is required, the system can be upgraded with the optional Enhanced aptX 16-/24-bit algorithm. Using the 24-bit format the highest quality for compressed audio transmission with the lowest delay is possible.

GatesAir (continued from page 26)

We plan to utilize the IP Links in a true redundant configuration so that our web stream remains on the air if either of our wide-area network connections is lost, or if we need to perform updates on the Intraplex IP Link hardware. A common benefit across all of these applications is ease of setup and use. GatesAir has made the process very simple to understand, and easy to replicate across any application. It is consistently the same process regardless of the network characteristics or type of connection. As T1 and ISDN become more difficult to maintain and IP solutions continue to evolve, there is no question that broadcasters should aggressively complete the transition to IP. Having redundant connections will provide excellent protection, while advanced error correction and mitigation techniques in products like IP Link will ensure the best possible quality and performance for any audio contribution and distribution needs.

Via the E1 interface, the system allows the transmission of multiple stereo or mono audio signals depending on the selected bitrate. Additional codecs can be connected to the main scheme via E1 using the Drop & Insert feature (which the company says offers

low latency) or alternatively via IP. With the IP version, each encoder can transmit five remote sites simultaneously. One network can consist of up to 99 systems, all of which can be managed via the ModNet application. With the optional Backup upgrade, | RADIOWORLD

users can secure remote sites with an automatic backup functionality if a network fails. Operators can also assign E1 as main distribution signal and IP as backup network or viceversa. Also possible is a pure IP transmission via two independent IP networks. If main and backup networks fail, you still have the possibility to play out an audio signal from an SD card.
