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.

NEW YORK, N.Y., June 2, 2010 – From political conventions to the news programming live from the Super Bowl, MultiDyne’s LiGHTBoX® field fiber transport system has helped CBS News deliver the top stories to viewers at home. MultiDyne, a premier provider of fiber optic, video and audio transport and routing solutions for broadcast and pro A/V applications, supplied its award-winning LiGHTBoX® to CBS News as part of their equipment for the transport of video from multiple locations during the broadcasting of various news programs.

“Broadcasting our regular news programming live from multiple locations, from the sand on South Beach to Sun Life stadium during Super Bowl, required that the equipment be very portable,” says Mel Olinsky, director of bureau operations, CBS News. “Working on location, we also have to transport HD signals over long distances, which would have been impossible with copper. The LiGHTBoX field fiber optic transport system provided all of our connectivity, over one multiple strand fiber cable, with no length restrictions.”

CBS News has used the LiGHTBoX extensively covering several major events, including political conventions and most recently, the Super Bowl. During the week leading up to the Super Bowl, MultiDyne’s LiGHTBoX transported video for several newscasts, including “The CBS Early Show,” “The CBS Weekend Evening News” and “Face The Nation,” which all broadcast live from different locations, including South Beach in Miami and Sun Life Stadium Miami Gardens. For these broadcasts, CBS News required the option of monitoring both HD and SD signals and wanted to transport video back and forth from various locations in South Florida to the network’s broadcast trucks, which were often parked far away from the shooting locations. A battery powered, bi–directional HD field fiber transport system designed for field and harsh environment applications, the LiGHTBoX was the ideal, portable solution to transport signals over distances as far as three football fields away during each on-location shoot.

Frank Jachetta, Managing Director, MultiDyne, stated, “On-location ENG and production can be very hectic, especially leading up to major events.” He concluded, “The LiGHTBoX takes some of the stress out of a live, remote shoot, as it is incredibly easy to transport, rugged enough for any field condition and extremely reliable. We’re thrilled that our LiGHTBoX plays a role in making sure that on-location CBS News broadcasts go off without a problem.”

Applications for Video Fiber Optic Transport

There are many applications for fiber optic communications.  Any application that requires high bandwidth or high bit rate communications is ideally suited for fiber optic transport.  The Television and Video industries are a perfect application for fiber optic transport.  Analog television is a relatively high bandwidth signal of more than 5 MHz.  Digital television or HDTV has bit rates of more than 3.0 Gbps.  High resolution computer graphics can have a bandwidth exceeding 165 MHz.  All of these television and video applications are ideal for fiber.

Broadcast Television Transmission

As mentioned earlier, television production and broadcast engineers have always sought out the best technology for media events such as the Olympics.  In the mid-80’s, fiber optic transport was introduced into the television industry.  Since that time that has been no looking back.  Fiber optics are used in all aspects of production and distribution of video and audio signals.

The state of the art for the transport of analog video is to use 12 bit video digital encoding.  The serial digital bit rate can vary from about 144 to 300 Mbps.  Please see the photo in figure 17 of a typical analog video and audio fiber optic link.

With the introduction of digital video in the 90’s, fiber optic transport continued to enjoy growth in the broadcast industry.  Digital video was encoded into 144 to 360 Mbps. These high bit rate video signals could only travel over copper up to about 300 meters.  Transport distance beyond 300 meters required fiber.

The transitioning to 100% digital or high definition television has created a need to transport signals with a bit rate as high as 3.0 Gbps.  High definition television or HD-SDI in its native or uncompressed from is 3.0 Gbps.  HD-SDI can only reach about 150 meters over a coax.  Once again, fiber is the only choice to reach distances beyond 150 meters.

Systems can be designed using many of the technologies described above.  We can mix analog and digital signal transport.  We can combine signals using Time-division and Optical multiplexing.  Figures 22 through 23 show typical applications.

Studio to Transmitter Fiber Optic Link, Figure 22

In the example in figure 22 we see a typical application of a Studio to Transmitter Link or STL.  A broadcast television station may typically reside in a downtown metropolitan area.  The television transmitter and satellite up and down links may be on a distance mountain top out side the city. This situation is a perfect application for fiber transport.  The system may require both analog video and digital video since the station may be in the midst of their conversion from analog to digital broadcast.  They will require signals in both direction to support downlink satellite video.  The diagram above shows a system with an eight channel CWDM and a variety of fiber optic transport links supporting analog video and audio as well as digital video in both directions.

Fiber Optic Trunking, Figure 23

The diagram in figure 23 shows an application where many channels of video and audio are combined together over one fiber for back-haul feeds, cable television, common carrier or Telco.   The system uses time-division multiplexing or TDM to combine groups of 8 channels of video with audio into single wavelengths.  The optical multiplexing or CWDM technology is used to combine the wavelgths with groups of 8 videos onto one fiber.  The combined technique of TDM and CWDM provides a  fiber transport capacity of more than 144 video channels on ONE fiber.

Early Applications for Fiber Optics

The United States armed services immediately took advantage of Fiber optics to improve their communications and tactical systems. In the early 1970s, the U. S. navy installed a fiber optic telephone system aboard the USS Little Rock. In 1976, the air force followed suit by developing its Airborne Light Optical Fiber Technology, ALOFT, program. The early successes of these applications spawned a number of military research and development programs to create stronger fibers, tactical cables, ruggedized, high performance components for applications ranging from aircraft to undersea.

Soon after, commercial applications began to appear. The broadcast television industry was always interested in systems that offered superior video transmission quality.  They embraced fiber optics video transmission.  The Broadcast Networks televising the Olympics every year utilized the newest technology currently available. In 1980, broadcasters of the winter Olympics, in lake placid, New York, requested a fiber optics video transmission system for backup video feeds. The fiber optic feed, because of its quality and reliability, soon became the primary video feed, making the 1980 winter Olympics the first use of fiber optics for a live television production in history.

The telecommunications industries took advantage of this new technology. In 1977, both AT&T and GTE created fiber optic telephone systems in Chicago and Boston, respectively. Soon after, fiber optic telephone networks increased in number and in reach. Network designers originally specified Multimode grated index fiber, but by the early 1980s, Singlemode fiber operating in the 1310nm and later in the 1550nm wavelength windows became the standard.  In 1983, British Telecom’s entire phone system used Singlemode fiber exclusively.  Computer and information networks slowly moved to fiber.  Today fiber is favored over copper due to lighter weight cables, lightning strike immunity and the increased bandwidth over longer distances.

In the mid 1980s, the United States government deregulated telephone service, allowing small telephone companies to compete with the giant,  AT&T.  Company’s like MCI and Sprint led the pace by installing regional fiber optic telecommunications networks throughout the world. Existing natural rights of way, such as railroad lines and gas pipes allowed these companies to install thousands of miles of fiber optic cable.   With this boom, the fiber transmission capacity struggles to keep up with the demand.  The optical fiber needed to increase in bandwidth over greater distances.
In 1990, Bell Labs sent a 2.5 Gigabit per second signal over 7500 KM without regeneration. With the use of soliton lasers and erbium-doped fiber amplifier or EDFA, the light pulses maintained their shape and intensity.   In the 1998, Bell Labs success went one better as researchers transmitted 100 simultaneous optical signals.  Each optical signal was at a data rate of 10 Gigabit per second and was transported for a distance of nearly 250 miles.  The bandwidth on one fiber was increased to 1 Terabit per second.  This was achieved using dense wavelength division multiplexing or DWDM technology which allows multiple wavelengths to be combined into one optical signal. Figure 10 illustrates a basic DWDM system.

Dense Wave Division Multiplexing, Figure 10.

DWDM technologies continue to develop as the thirst for bandwidth increases. The potential bandwidth of fiber is 50 Terra-Hertz or better.  DWDM technology has decreased greatly in cost and power consumption over the years.  The DWDM laser technology requires strict temperature control and compensation.  This makes the device draw high amounts of power and adds to the system costs.  Today it is still a rather expensive form of optical multiplexing.  More commonly used in the broadcast television industry is coarse wave division multiplexing or CWDM.  CWDM technology gives the ability for up to 18 simultaneous optical signals on one fiber.  This gives a usable bandwidth of more than 70 gigabits per second.  CWDM optics are relatively common that operate at 4 Gbps.

The FCC mandated that all broadcasters switch from analog to digital or high definition television standards.  This presented researchers with the challenge to provide high bandwidth fiber optic transport for high definition television.

Beyond broadcast television, however, consumers are pushing to have broadband services, including data, audio, video delivered to the home. Broadband services allowed interactive communications for both consumers and businesses, bringing to reality interactive video networks, interactive banking, shopping from the home, interactive distance learning just to name a few applications. Video on Demand hit a brick wall in coaxial cable television systems that excelled at carrying the same Video signal to everyone, but failed as a means to route switch signals. That will not be true for the next generation of fiber optics technology. Video transmission and fiber optic technology are naturally suited to one another.
