MULTIDYNE DEBUTS THE DVI-ONE-E, A LOW-COST SOLUTION FOR DVI AND HDMI OPERATING OVER ONE FIBER AT INFOCOMM 2010

June 10th, 2010

Extends DVI and HDMI Distance Limitations


LAS VEGAS, JUNE 9, 2010
MultiDyne Video & Fiber Optic Systems, a premier provider of fiber optic-based video and audio transport solutions for broadcast and pro A/V applications, is introducing the DVI-ONE-E, a low-cost solution that allows either DVI or HDMI to operate over ONE fiber, at InfoComm 2010 (Booth C4823). Designed to extend DVI and HDMI distance limitations, this cost-effective solution is the first to offer users bi-directional communication over ONE fiber for full HDCP copyright and EDID functionality.

Recognizing the need for high-resolution graphics and video image transfer over long distances, MultiDyne’s DVI-ONE-E focuses on maximizing visual quality, with pixel-for-pixel image transport, a 100 percent 24-bit scan rate and no contouring or bit reduction. The fully uncompressed DVI-D or HDMI signal is transported over ONE fiber supporting WUXGA up to 1920×1200 and is 100 percent transparent with no frame dropping.

The DVI-ONE-E supports DVI and HDMI signals with the use of a cable adaptor. MultiDyne’s DVI-ONE-E also responds to market demand for a locking HDMI-connector, seamlessly transporting the HDCP and EDID information along with the HDMI or DVI video signal. The product also allows transmissions of up to 1000 meters over multimode fiber and ensures that HDCP encoding remains intact and unmodified throughout the entire process.

“The transport of DVI and HDMI copyright protected material continues to be very important for the A/V, home theater and permanent installation markets,” says Frank Jachetta, managing director, MultiDyne. “With the DVI-ONE-E, installers can now send video from a central DVD or Blu-ray player to a monitor or display to distances of up to 1000 meters away – and most importantly, over a single fiber. With more complex installations of HD video over longer distances, and in projects ranging from schools to hotels and conference centers, this is a major benefit for our users.”

The DVI-ONE-E optical transport design is ideal for secure video and audio communications in command and control facilities. The lack of EMI characteristics also makes the DVI-ONE-E the perfect choice for medical instruments and airborne applications. This solution includes external power supplies and a USB power port. Alternatively, a free USB port can be used from the video source to power the transmitter and a USB port on the monitor can power the receiver, eliminating the need for two external power supplies.

MultiDyne’s DVI-ONE-E fiber link can be the solution for a wide variety of applications including medical and MRI displays, advertising and signage, sporting and concert video displays, video walls as well as in the commodity and stock exchanges.

NASA LIFTS OFF WITH MULTIDYNE’S VIDEO AND FIBER OPTIC SOLUTIONS

April 27th, 2010

HD-1500HD-1500 and RGB-5000 Solutions Give the Public a Glimpse Inside NASA Control Room


LOCUST VALLEY, NY, APRIL 27, 2010
– MultiDyne Video & Fiber Optic Systems, a premier provider of fiber optic-based video and audio transport and routing solutions for broadcast and pro A/V applications, is helping NASA TV document history at the NASA Goddard Space Flight Center in Greenbelt, MD. With several major space missions, NASA TV’s production team called upon MultiDyne to provide its HD-1500 fiber optic link and RGB-5000 systems to transport video from the center’s Space Telescope Operations Control Center (STOCC). These solutions moved video from across campus to the NASA TV control room, capturing several exciting moments in national history and displaying them for the public on NASA TV.

Two years ago, the TV production staff at the NASA Goddard Flight Center began looking for a video transport solution that would take advantage of the NASA campus’ robust fiber optic infrastructure. Production staff met with MultiDyne representatives at the National Association of Broadcasters (NAB) convention to discuss their needs and equipment criteria for NASA projects. As MultiDyne equipment features HD video capability and adheres to SMPTE standards, the center’s TV production manager selected the HD-1500 and RGB-5000 solutions, with plans to upgrade to the DVI-6000.

The MultiDyne HD-1500 supports the distribution of digital signals from 5 Mbps to 1.5 Gbps over singlemode fiber, transporting video from three Panasonic cameras installed in the STOCC to the NASA TV control room.  From there, video of the action-packed control room is used on NASA’s full-time satellite TV channel, on a daily “STOCC Update” TV program as well as for B-roll for various news organizations, documenting history for the public. In addition to the shots of the STOCC, the TV production staff also used MultiDyne’s RGB-5000 to transport real-time animation from NASA’s telemetry programs, incorporating high-resolution data from the spacecraft into NASA TV’s live programming. Recent NASA missions that were filmed include Servicing Mission 4, the final servicing mission for the famous Hubble Telescope, and the landmark launch of the Lunar Reconnaissance Orbiter (LRO), which represents the first step in NASA’s return to the Moon.

“Using our products, NASA TV has been able to design a high-tech system for transporting video across its campus, making sure that HD video of NASA’s milestones is available to the public,” says Frank Jachetta, managing director, MultiDyne. “It’s a thrill for us to be able to work with such a visionary agency as NASA and we look forward to continuing to provide it with our proven solutions for all of its fiber optic video transport needs at the Goddard Center.”

MULTIDYNE’S MULTI-FORMAT HD-1500 FIBER OPTIC LINK TO HIT THE RED CARPET AT THE VANCOUVER WINTER GAMES OPENING CEREMONIES

February 2nd, 2010

MultiDyne - LiGHTBoXLOCUST VALLEY, NY, FEBRUARY 2, 2010 – As the Olympic torch is carried into BC Place Stadium for the official opening ceremonies of the Vancouver Winter Games, MultiDyne Video & Fiber Optic System’s HD-1500 Fiber Optic Link will be in action transmitting signals from the announcer booths and red carpet. MultiDyne, a premier provider of fiber optic-based video and audio transport and routing solutions for broadcast and pro A/V applications, was chosen to supply its HD-1500 and LiGHTBoX® field fiber transport systems for the Canadian broadcast by CP Communications, the largest provider of wireless equipment to the sports broadcasting industry.

For this year’s opening ceremonies, CP Communications required the option of monitoring both HD and SDI signals and wanted to transport video back and forth from its client’s announcer booths to the network’s broadcast trucks. As a longtime user of MultiDyne equipment and with over 60 HD-1500 links in-house, CP Communications knew that the HD-1500 was one of the few products on the market designed for monitoring multiple formats in one single unit. With this in mind, the HD-1500 was incorporated into booth kits assembled for the client’s French, English, combined French/English mix and red carpet announce booth kits of equipment to be used during the Games’ opening ceremonies.

“Reliable products are important for any project, but the Olympics and the live broadcast of the opening ceremonies absolutely steps up that need a notch,” says Kurt Heitmann, senior vice president of sales for CP Communications. “Security is also tighter for a major event of this stature, so you have to be able to rely on the equipment you ship in because you don’t have the opportunity to replace a product if it stops working. We have never had a failure with a MultiDyne product, and that gives us the confidence to recommend the HD-1500 to our customers, who are very comfortable using a high-quality solution like MultiDyne’s HD-1500 at this year’s opening ceremonies.”

Beyond its reputation with CP Communications for reliability, Heitmann also touts the HD-1500 as user-friendly, noting that the solution is easily rack-mountable unlike other smaller devices on the market that do not come with rack mounts. Further, as other products have much smaller displays, Heitmann appreciates the HD-1500’s large LED indicators for data rate, HD, lock and power that aid users who need to quickly identify certain functions.

MultiDyne - LiGHTBoX Rack FrontIn addition to the HD-1500 links, CP Communications will also provide clients at the Olympics with custom LiGHTBoX field fiber transport systems that will be used to transport audio and data bi-directionally as well as provide two-wire to four-wire communications for the camera operator.

“With MultiDyne, you can customize just about any product,” says Heitmann. “Their customer service is above and beyond and they are very flexible; they will work with you to develop unique, cost-effective products for you and your customers. We worked closely with them on the custom LiGHTBoX units and we just wouldn’t have been able to do that with some other manufacturers. As a company, we think MultiDyne is tops.”

The HD-1500 and LiGHTBoX units will be used at this year’s Vancouver Winter Games beginning February 12, 2010. For more information on the HD-1500 or LiGHTBoX, please visit www.multidyne.com.

TV Technology User Report: MultiDyne Helps Casino Create Visual Oasis

September 9th, 2009

MultiDyne has had the privillege of working with some amazing clients, including the Peppermill Casino brand in Reno, Nevada. Below is their project manager Aaron Lines’ take on using the MultiDyne HD-1500 to create a visual oasis at the hotel properties.

This report was first published in TV Technology – http://www.tvtechnology.com/article/86544.

WENDOVER, NEV.
When you step into any of the Peppermill Casino’s gaming areas, either here or at our Reno, Nev. location, you’ll enter a fantasy world of stunning architecture, HD video and sizzling action. All of our properties place a major emphasis on creating the most exciting and luxurious atmosphere for our guests. That’s why, when I was tasked with complementing our casino design with a world-class video and entertainment system, I needed a video transport solution that could continue the standard of excellence we demand as a company.
When I began my planning for the project, there were only a few companies that had fiber systems for transferring HD video over the distance involved. After meeting with MultiDyne, they assured me that there was no challenge in distributing our 16 HD-SDI streams to all of our Wendover properties, as well as moving video from one side of our Reno property to the other.
During the selection and testing process, a critical concern was in avoiding degradation of our high-resolution video during transport. The HD-1500 certainly passed this and all of the tests. Our displays give guests the feeling that they have walked into a new visual oasis, heightening the feeling of excitement in our gaming areas.

Today, the HD-1500 system continues to serve as a crucial component in our highly proprietary and customized equipment configuration. It is used to transport both video and embedded audio. The HD-1500 works flawlessly and has been used 24 hours a day, seven days a week for two years now with absolutely no failures.

As this level of broadcast quality distribution is very unusual for a casino, it was important to work with a manufacturer who had solid experience in broadcast video, and also understood gaming facilities. MultiDyne’s very professional customer service and attention to our needs provided the comfort level needed to purchase these new products, and I’ve continued to rely on MultiDyne for these services over the years.

Broadband RF and Satellite Link Transport

February 7th, 2009

Broadband RF and Satellite Link Transport

There are many broadband RF applications for fiber.  One important application is satellite uplinks and down links.  Commercial satellites, for long wavelgths applications, typically use an Intermediate Frequency or IF signal as a means on communication. The IF signals is typically 70 or 140 MHz.  The signal has a limited transport distance over copper coax.  The noise level and sensitivity of a satellite system will suffer with the use of copper coax.  The relatively high bandwidth and noise sensitivity issues make IF signal transport ideal for fiber.  As pictured below in figure 32, fiber transport solutions are available for IF satellite applications.

Consumer and residential satellite is findings it way into more and more commercial, corporate and military applications.  Consumer satellite equipment is used in many applications as a source of information and news.  A large corporation may use consumer satellite instead of cable for news and informational content.  In a corporate building or military bunker, the satellite dish may be on the roof many floors above the control or conference room.  The L-Band signal has a bandwidth from 950 to 2150 MHz.  A coax run will not transport the L-band satellite signal very far.  A consumer satellite dish is small due to a shorter wavelength.  It typically has a device called a Linear Noise Block or LNB.  The LNB is an active device that receives the satellite signal and amplifies to be sent down the coax to the receiver.  The LNB requires a DC voltage which is typically generated by the receiver and sent up the coax.  If we use a fiber link, the DC voltage needs to be generated on the dish side of the fiber link.  When designing an L-Band fiber link, the system needs to provide the appropriate LNB DC power.
