AMSTERDAM, NETHERLANDS, AUGUST 24, 2009 – 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 bringing its LiGHTBoX™ fiber optic field transport system with brand new features to IBC 2009 (Stand 2.A54).

Addressing industry demands for fiber transport applications where battery-powered equipment is required, new features on the popular LiGHTBoX product include 3G capability, a boon for users working with high definition video. The LiGHTBoX is also now compatible with two of MultiDyne’s flagship products, the DVI-6000 and COMMS-2000. Both products can be integrated into the LiGHTBoX, with the COMMS-2000 for use anywhere to provide a two to four wire bridge for intercom. Applications for the LiGHTBoX with DVI-6000, a product designed for the transport of DVI-I, RGB-HV and DVI-D over ONE fiber, include outdoor digital signage and common area video display at a stadium or ball park. This solution ensures that fans do not miss a second of the game when watching the concession-area displays due to the efficiency and high resolution of the DVI display.

“MultiDyne is focused on providing fiber solutions for any requirement, including field and harsh-environment applications,” says Frank Jachetta, senior vice president of sales and operations. “The LiGHTBoX addresses a need for a road-ready, robust fiber solution that serves the needs of our ENG and sports customers.”

The LiGHTBoX is fully customizable offering virtually any signal configuration and can be linked via tactical fiber cable to the MultiDyne DVM-2500, HD-1500, HD-3000 and HEMC-4000.

High Resolution Graphics and Video Transmission for DVI

The quality and fidelity of a signal over short and long distances is difficult to maintain over copper.  As signals increase in bandwidth and bit rate, it becomes more and more difficult for systems to transport these high bandwidth signals even a short distance over copper.   This becomes very apparent when working with high resolution vided and graphics.

A computer generated RGB or UXGA signal at 1600 by 1200 pixels requires and analog bandwidth of close to 500 MHz.  If the signal is digitized, requires and data transport bit rate of 3 to 4 Gbps.  How do we transport these signals?  The answer is “Not very far over copper”.   There are many copper based products that will transport these signals but at a cost in performance and video quality.

High bandwidth signals such as RGB, DVI and HDMI all benefit by the use of fiber.  Systems like the one pictured below in figure 28, offer state-of-the-art fiber transport over one fiber for RGB/UXGA Video, Audio, Data and Ethernet.

Many applications today require the same video or graphical signal to be displayed on a series of monitors.  An example may be an airport terminal where arrival and departure information is displayed every 100 feet.   This application requires a long daisy-chain of units that can drop and repeat the same signals to each monitor every 100 feet.

System are available with the drop and repeat or daisy-chain feature.  As shown in figure 29, one transmitter can send the video signal to the first receiver.   The first receiver decodes the optical signal and generates an output for the local monitor.  The receiver also repeats and re-generates the optical signal to send to the next receiver in the chain.  This technique saves on installation and equipment costs.  The alternative would be to run a fiber from each monitor back to the control room.  Instead, one fiber can feed many monitors.
