Markertek Supports Philadelphia Eagles With SMPTE Fiber, Customer Service

Fri, 24 Oct 2014 11:44:17 -0400

As part of the $125 million renovation of Lincoln Financial Field, the Philadelphia Eagles added 10 Sony F55 4K cameras to capture in-game content. To connect those camera locations to the video-control room, the team tapped Markertek to supply SMPTE fiber, tactical fiber, and telecast gear.

“Markertek is my go-to for any thing at all for our production, and that’s probably because of their customer service and the fact that they do handle a lot of their own stuff,” explains David Sullivan, building AV engineer, Philadelphia Eagles. “I’ve never had a problem, but I know that, if I’m buying their brand [and] I had a problem, they’re going to back it up.”

The Eagles selected Markertek’s SMPTE fiber cable after testing several brands side-by-side for durability, cable size, and more. “We actually had some other SMPTE cable in the building that fell apart already, but the Markertek cable has stood the test of the first six weeks of football,” Sullivan continues. “So far, so good."

Manufactured in the company’s LEMO-, Neutrik opticalCON-, and Canare Fiber-Certified Fiber Lab in Saugerties, NY, Markertek’s SMPTE fiber is hybrid fiber-optic and copper cable that connects the camera-control unit (CCU) of each F55 with the video-control room. Located on The Linc’s press level, the control room feeds content to videoboards throughout the venue, including two 10-mm end-zone displays manufactured by Panasonic.

“From start to finish, we’re manufacturing some of the highest-quality fiber optics in the industry,” says Dan Coscarella, proprietary sales manager, Markertek. “Our defined specs exceed what the industry spec is, so we’re really building a quality brand for our customers.

Markertek also supplied the team with tactical fiber cables, which are not installed in a fixed location. Rather, the cables are kept spooled and can be deployed for any live-production need: capturing fan reactions in the stands, halftime events on the field, postgame reaction in the studio.

The SMPTE and tactical fiber were added to the Eagles’ existing triax infrastructure as part of the renovation, which was completed prior to this season. Diversified Systems installed and integrated the venue’s fiber infrastructure in addition to serving as the video-control-room integrator.

“There’s 500 varieties of each product, but we don’t want to sell the one we want to sell. We want to sell the one that makes the most sense for the particular customer, and, to get there, we spend a lot of time training the staff and making sure the staff knows what their customers really are looking for,” says Coscarella.

Eurovision Americas To Offer IEEE BTS ‘Bridging the Gap’ Training Course

Thu, 23 Oct 2014 09:45:39 -0400

The IEEE Broadcast Technology Society (BTS) announced that Eurovision Americas Inc., the U.S. arm of the European Broadcasting Union (EBU), will host the next session of the society’s “Bridging the Gap” training course, Dec. 8-9, at its Washington, D.C. headquarters. During the interactive seminar, attendees will learn how to address the knowledge gap between IT technologists and video specialists in order to improve operational efficiencies in broadcast facilities. The course is open to Eurovision Americas employees, members of the broadcast community, and the general public at a rate of $395.

“Operational efficiency is critical for the success of any broadcast facility, and especially in a 24-hour live news and sports environment such as ours,” said Jay B. Hahn, vice president and engineer-in-charge, Eurovision Americas. “By hosting the IEEE BTS ‘Bridging the Gap’ seminar, we can ensure that our employees and members of the broadcast community are up to speed on both IT and broadcast technologies. Gaining an understanding of the complex relationships that exist between media and information processing technologies is imperative for modern broadcast facilities that are operating under a file-based workflow.”

“Bridging the Gap” training is ideal for engineers and senior level technicians looking to gain a deeper understanding of a wide range of current and emerging technologies used in broadcast facilities. Taught by well-known broadcast industry experts Wes Simpson and John Luff, the course covers a broad range of topics such as baseband digital video transport, video servers, data networking for broadcast facilities, metadata, archiving, and video compression. After completing the course, attendees are able to resolve day-to-day issues more efficiently.

Attendees also receive a printed copy of the course materials featuring detailed diagrams and tables for future reference. IEEE continuing education credits are available to those who complete the course.

The IEEE BTS is currently accepting hosts for future sessions in 2015. Each two-day seminar accommodates 30 or more attendees.

Host organizations may be entitled to receive a discount on student tuition, and IEEE BTS members receive a 5-percent discount toward tuition.

Online registration for the seminar is now open and can be accessed at http://goo.gl/bGsBxI.

Live from SMPTE: Belden Talks 12 GHz Coax for 4K Needs

Wed, 22 Oct 2014 10:40:28 -0400

Coax will still play a role in the world of 4K and 12 GHz as Steve Lampen, Belden, multimedia technology manager, laid out plans for a 12 GHz single link coaxial cable that the company plans on introducing in the first quarter of 2015.

“Single link 12 GHz requires new design,” explained Lampen. One of the big changes will be doubling the Nyquist rate in order to give users longer distances to play with. The current 1694A cable, for example, will be able to reach distances of 69 meters and still be able to send a high-quality signal.

“Is 69 meters far enough? Time will tell,” said Lampen. The cable will also be thicker and also include a tri-shield, giving it a -20 dB improvement over foil/braid at high frequencies.

“By bonding the foil to the core we will improve return loss and ruggedness as at 12 GHz there are super tiny wavelengths and even subtle changes in the difference in distance between the foil and core can have huge effects on the signal,” explained Lampen. “So by bonding the foil to the core that distance will not change even when the cable is bent.”

The cable will be introduced early next year and Lampen says it will allow those who are comfortable working with coax to not have to make the move to fiber in order to embrace 4K. The only remaining uncertainty is when the connectors will become available, as the 4K signals will require improved connectors. Using existing connectors, said Lampen, would be like using wooden wheels on a sports car and going 500 miles per hour.

Duplex

A duplex communication system is a system composed of two connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for a communication "two-way street" between two connected parties or to provide a "reverse path" for the monitoring and remote adjustment of equipment in the field.
Systems that do not need the duplex capability include broadcast systems, where one station transmits, and everyone else just "listens". A half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously). Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying. A full-duplex, or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex, since they allow both callers to speak and be heard at the same time.

Understanding Fiber Optic Attenuators

Attenuators are used with single-mode fiber optic devices and cable to filter the strength of the fiber optic signal. Depending on the type of attenuator attached to the devices at each end of the fiber optic cable, you can diminish the strength of the light signal a variable amount, measured in decibels (dB).

Why would you want to filter the strength of the fiber optic signal? Single-mode fiber is designed to carry a fiber optic signal long distances—as much as 70 kilometers (or 43.4 miles). Fiber devices send this signal with great force to ensure that the signal, and your data, arrive at the other end intact.

But when two fiber devices connected with single-mode fiber cable are close to each other, the signal may be too strong. As a result, the light signal reflects back down the fiber cable. Data can be corrupted and transmissions can be faulty. A signal that is too strong can even damage the attached equipment.

Because it’s probably not feasible to move your fiber equipment farther apart, the easiest solution is to attach an attenuator to each fiber device. Just as sunglasses filter the strength of sunlight, attenuators filter the strength of the light signal transmitted along single-mode fiber cable. Within the attenuator, there’s doping that reduces the strength of the signal passing through the fiber connection and minute air gaps where the two fibers meet. Fiber grooves may also be intentionally misaligned by several microns—but only enough to slow the fiber optic signal to an acceptable rate as it travels down the cable.

Before selecting an attenuator, you need to check the type of adapter on your fiber devices. Attenuators typically fit into any patch panel equipped with FC, SC, or LC adapters that contain either PC or APC contacts. In addition to the type of adapter, you also need to determine the necessary attenuation value, such as 5 or 10 dB. This value varies, depending on the strength of fiber optic signal desired.
