GatesAir, a global leader in wireless, over-the-air content delivery solutions for TV and radio broadcasters, has helped Stephens Media Group of Medford’s country station KAKT(FM) become the first commercial HD Radio broadcaster in the Medford, Oregon market. The station is now delivering two HD Radio channels alongside its main FM program, using a complete GatesAir HD Radio Gen4 solution with high-efficiency transmission, embedded signal processing, and IP networking gear.
The Stephens Media Group of Medford engineering team worked closely with GatesAir channel partner SCMS to identify a solution that would help launch an HD Radio service while also transitioning to solid-state transmission. KAKT selected a GatesAir Flexiva FAX20 (20kW) air-cooled transmitter, retiring tube transmitters that had grown challenging to service. Klein-White Broadcast Engineering, a full-service design and engineering firm, added value through turnkey installation and commissioning services that brought the new solid-state system to air quickly.
“Solid-state brings a great deal of new maintenance and efficiency benefits over tubes, and spare parts have become expensive and tougher to find,” said Dan Sullivan, Chief Engineer, Stephens Media Group of Medford. “The Flexiva is half the size of our tube transmitter, which reduces cooling requirements and returns a great deal of space in a rather small room. Our new transmitter is very accessible for maintenance, with a plug-and-play, hot-swappable design that will simplify our workload and ensure we can service the transmitter while on the air.”
The FAX20 accommodates the FM, HD1 and HD2 channels, with an HD3 channel to be added in the future. GatesAir’s Flexiva FMXi 4g embedded HD Radio solution provides a single Importer/Exporter to manage the audio and data within Stephens Media Group of Medford’s IT infrastructure. This eliminates the need for separate systems with moving parts, and centralizes all related signal processing and multiplexing.
The FMXi 4g also time-aligns the analog and digital program audio without the need for a separate modulation monitor or other hardware unit that was required before GatesAir’s innovation. KAKT uses a traditional microwave STL system to transport its FM signal, and GatesAir Intraplex IP Link 200 codecs to network both HD Radio channels over IP. Sullivan adds that the IP Links operate reliably over what he calls “a slow network,” with no obvious signs of packet loss as the program audio moves from the studio to the transmitter site over IP.
“The automatic delay option in the FMXi 4g calculates the diversity delay for analog/digital time alignment, and sends the synchronized signals into our FAX exciter,” said Sullivan. “That alone has saved us a lot of money, and the built-in functionality removes another device from the infrastructure that I would have to manage. The ability to remotely tap into all of these systems has also been useful, and the GUIs on the FAX exciter and transmitter provide clear and important data around PA temperature and other performance parameters.”
Feedback from the Medford community has been positive since launching the new system, particularly in regards to HD Radio audio quality. Sullivan notes that the new transmitter is also covering the market with a much stronger broadcast signal, ensuring that its FM and HD programming reach the largest possible audience.
“KAKT is an ideal example of how a community-oriented, smaller market radio station can cost-efficiently launch new digital services and transition to IP networking on a reasonable budget,” said Ted Lantz, Vice President and General Manager, Radio Product Group for GatesAir. “And with a third HD Radio channel on the way, Stephens Media Group of Medford can focus more on serving their listeners instead of servicing an older transmission system that would continue to escalate operational costs and maintenance. They can now look forward with a high-efficiency architecture that represents revenue growth over complex engineering requirements.”

The German system integrator was on site with their Singapore entity and held responsible for the system’s design, implementation and service on-site to give the production company a broader and uninterrupted wireless camera coverage, specifically in the PIT area.
Three sets of Silvus 4200 radios with Haivision Makito X encoders/decoders using HEVC (high-efficiency video coding) and SRT (secure reliable transport) were deployed. The solution from both companies provided a combination of a wireless IP MESH-network and a highly efficient low latency encoding/decoding system. The team-play of Silvus and Haivision solutions are the perfect combination to provide a low-latency wireless camera system for broadcast and live TV-production.
Because of the overall area conditions Top Cool Productions previously was unable to provide a wireless connection between Tx and Rx, due to their legacy wireless system, offering only point-to-point and line-of-site connection. Therefore they needed a system capable of securing a full coverage of the PIT area to interview drivers and team members and overcoming existing areal barriers. This is where Silvus and Broadcast Solutions came into play.
The PIT area stretching around 200 m and the OB Van in charge had to struggle with several obstacles blocking a direct line-of-site connection. With only three Silvus radios forming a MESH-network Broadcast Solutions enabled a full coverage along the PIT area, including PIT rooms and holding areas without nearly any dead spots. With the fluid, self-healing, self-forming MESH-network topology coupled with Haivision’s HEVC and SRT, providing ultra-low latency (20msec) at 6Mbps stream of HD video, the result was a very robust wireless camera system operating on ad hoc coverage even in non-line-of-site situations.
Flashback on the first IP-based broadcast centre with state-of-the-art platforms and numerous innovative production and distribution applications to answer the needs of today and tomorrow media players.
The 36,000 square meter IP-based facility supports 24/7 broadcasting of more than 35 channels, among those RTL Télé Lëtzebuerg, Chamber TV, Luxe.TV (Luxembourg), RTL TVI, Club RTL, Plug TV (Belgium), RTL4, RTL5, RTL7, RTL8, RTL Z, RTL Crime, RTL Telekids, RTL Lounge (Netherlands), RTL9 and AB Groupe movie channels and Altice Group channels (France), RTL Hungary (Hungary) and Love Nature, Love Nature 4K, Blue Ant Extreme, Blue Ant Entertainment (Singapore).
The broadcast centre was three years in the making and features an end-to-end IP infrastructure and well-conceived data IT network that manage mostly HD (and some 4K) content and channels.
“IP-based platforms allow us to rapidly setup new channels,” comments Costas Colombus, Technology Projects & Support Director at BCE. “Whereas it is for continuous or ephemeral channels, we are able to give a fast answer and start broadcasting the content worldwide.”
The new broadcast centre is located in in the centre of Europe. All the radio and television production facilities and playout centre operations employ the latest IP-enabled equipment from technology suppliers like Arista, Grass Valley (GV), Isilon, Juniper, Lawo, Harmonic.
Advanced research and systems integration
All of the equipment and systems were installed and tested by BCE. When plotting out goals for the new building, BCE engineers wanted the new infrastructure to be both future-proof and able to adapt to new workflow challenges as needed.
When it first began to consider replacing its traditional SDI systems in 2014, the available IP technology wasn’t suitable for real-world deployments or mission-critical broadcast use, and most solutions were proprietary. The process resumed in 2015 with six months of intensive interoperable testing. For BCE it was critical that the IP solution had the same quality of service and reliability achieved in the SDI world, but with an increased level of scalability, stability, propagation delays and synchronization.
Working with engineers at The Institut für Rundfunktechnik GmbH (IRT) research centre, BCE began looking at the SMPTE 2022-6 IP spec as a way to connect all of the disparate systems and have them communicate as a fully networked system. This would streamline the production of content and get it to the right TV, radio, and web platform for its own purposes, as well as support the numerous playout and other services it provides for major U.S. content distributors like CBS, NBC Universal, Warner Brothers Television and others.
Laurent Seve, Marketing Manager at BCE, said that when their team began researching different ways of implementing IP technology, they recognized that what was needed was a facility that was significantly different to what had been done in the past.
“The new facility is flexible enough to handle all types of content creation and distribution projects,” Laurent Seve said. “The collaboration between the IT and broadcast teams led to new types of workflow methods and allowed to get the most out of the systems.”
Technology provider Grass Valley was brought in to help test a series of IP workflows. Fiber-optic cabling, which is bandwidth-friendly, supports the various systems and connects all floors of BCE. There’s also lot of Cat6 cable installed throughout the building for things like data networks, online access and a variety of control (KVM) functions.
“The IP-technology allowed the move to a fiber-based cabling infrastructure,” said Alain Prim, Technology Projects Manager at BCE. “All the areas of the building are connected through a reduced amount of cables which are able to transport a far higher number of services. The multiple changes in media services are now easier to manage without the need of modifications in the basic cable or hardware structure.”
Indeed, BCE is now responsible for the playout of over 35 regional and international channels, from its Luxembourg Network Operations Centre (NOC). This NOC also manages transmission sites, located on remote sites in Luxembourg and Germany. Online and available 24/7, the NOC team ensures the continuity of BCE’s and its customers activities by answering all queries and taking targeted actions.
Thanks to the IP solution implemented, the NOC can fully operate, and control BCE’s Teleport located miles away. All the antennas, uplinks and downlinks, receivers, etc. are remote controlled over IP by the NOC.
The core of the production activities features a 1,000 sqm datacentre with one-megawatt capacity and 366 floor-to-ceiling equipment racks that store and distribute the content (and metadata) internally and outside the building. In-row water-cooled airflows keep the systems at optimal temperatures.
“Numerous customers selected our datacentre for its flexibility, its advanced infrastructure and the access to numerous services,” comments Xavier Boschian IS&T Director at BCE. “As a result, we have already built a second datacentre and are looking to extend the platform to welcome more customers.”
System and content security
Securing the operations of its customers is BCE’s priority, the new IP workflow of RTL City facilitates connections setup to remote sites for disaster recovery (DR) platforms.
Data is handled with the utmost care and stored in BCE’s storage facility. Whereas it is administrative, financial or media content such as videos and audio, BCE holds several solutions including a 20 Petabytes nearline Digital Library, online and offline solutions as well as S3 cloud backup and storage (through its flagship solution: itstored).
There are also three diesel generators for backup power, with UPS technology everywhere for system resilience. In fact, every piece of equipment is connected to two independent electrical power supply paths—with intelligent sensing and monitoring that will automatically connect the device to a third backup supply if two live and active electrical supplies are not detected.
Linked via dark fibre to BCE’s headquarters, the DR site features emergency workstations, playout platforms for the premium channels, a digital library with several Petabytes and a datacentre.
Flexible production and remote control
Due to its IP backbone, several production studios can share control rooms if necessary, with one control room controlling various productions at once. There are also several audio mixing rooms, and advanced lighting grids in the production stages.
About 30 post-production suites support a number of radio and TV channels as well as other outside client needs. These are based around GV edit stations with networked Isilon storage.
All the radio studios have voice-activated broadcast cameras in them so that when a particular on-air talent is talking, the appropriate camera goes live. The system has proved to be very flexible for full spec broadcasting on a main channel as well as generating a web stream.
“We have always anticipated the merge between IT and Broadcast technologies and decided to stop talking about new solutions and change the complete workflow of our activities to IP,” said Andreas Fleuter, Technical Infrastructure & SLA Director at BCE.
IP backbone makes the difference
While the internal network can be expanded as needed, the initial deployment is based around the VSF TR-03 protocol for distributing video over IP, using SMPTE ST 2022-6/7 and AES67 redundant IP streams. This includes multi-level routing support of the VSF TR-03 protocol for audio breakaways.
The building’s architecture supports 10Gbe, 25Gbe and 40GbE connectivity. GV provided an end-to-end IP routing system to meet this, complete with full SMPTE ST 2022-7 redundant hitless operation and seamless recovery from interruption to one IP link. GV also supplied a massive routing matrix that can handle 1036×1584 2022-6 video flows and 1180×1728 AES67 (each x8 AES3) audio flows.
Other GV IP technology in use includes its Kahuna IP production switchers, IQ-Edge IP processing systems, IP routing control systems and multiviewers. These are fully networked to a Lawo Virtual Studio Manager (VSM) control layer that manages all of the IP signals and tells the routers where (and when) to send them. There’s also a GV monitoring system that collects data from the IP sub-system, along with a direct interface to a Skyline Communications DataMiner network management and monitoring layer.
Evolution and Revolution
With the new IP infrastructure in place, any room or machine in the building can be accessed and used by any other with just a few router settings. In addition, operators at RTL City can now launch a new channel in a few days, as opposed to the 4-5 months it took previously.
“Technology and innovation are in BCE’s roots,” comments Tun Van Rijswijck, COO at BCE. “This all-IP infrastructure was meant to break the barriers and open to new linear and non-linear developments. Our recent acquisitions and innovations strengthen our conviction that we are on the right track.”
As a matter of fact, since the opening of RTL City, several channels selected BCE as their technological partner: Altice launched a multiplayout control room broadcasting numerous channels over Europe including a Live sport channel in 4K over IP and Blue Ant Media (BAM) launched Love Nature in HD and 4K in multiple languages.
With the acquisition of Freecaster, BCE enriched its portfolio with new hybrid solutions directly connected to the Cloud. Freecaster’s platform was perfectly integrated in BCE’s IP workflow, granting access to live streaming solutions, reaching new horizons with social network but also delivering OTT solutions, VoD portals, replay platforms and more.
“Freecaster is a strong asset for BCE, on one hand it answers our customers’ expectations for new OTT solutions and extension of our content delivery network and on the other hand it opens new markets like sports, institutional, music and fashion related customers.” Adds Tun Van Rijswijck.
On the production side, BCE created a new solution (StudioTalk) facilitating the launch of new programs. StudioTalk is geared up with PTZ cameras, microphones, digital branding and a touchscreen interface to manage the content, the production and the delivery. The solution gives an affordable alternative to cover events that were not financially viable before.
The results are clear, radio goes visual, television shows production is easier, events are covered anywhere, ephemeral studios are installed everywhere… BCE is steering the market to video and screen multiplication.
“Innovation has always paved the way of BCE activities. The all-IP infrastructure leaded our company to hybrid and cloud while increasing the distribution of media content on a global scale. The acquisition of Freecaster and its integration in our workflow was a significant move to the non-linear market. Tomorrow, the engineering of new solutions will enhance the development of BCE in the digital media world.” Concludes Frederic Lemaire, CEO at BCE.
