DVI stands for Digital Video Interface. Both TV and PC video can be in
digital form rather than the traditional analog. The advantage of the
digital signal is that it can give you a virtually perfect image. Gone
are analog artifacts such as ghosting, smearing, noise, snow, shaking,
or out-of-focus images on your display.
DVI is fundamentally a 24-bit digital RGB interface based on a signal
technology called Transition Minimized Differential Signaling (TMDS).
A single DVI "link" consists of three pairs of differential, low-voltage
digital signals, one each for the red, green and blue components plus a
fourth pair for transmitting a pixel clock. The data for each 8-bit RGB
component is transmitted as a serial bit-stream with a maximum bit rate
of 1.65 Gigabits per second (Gbps). In today's evolving technology,
though DVI can be used for TV, it is almost exclusively used in high-end
PCs. The DVI for television application has migrated into HDMI

Video over UTP (Cat5/5e/6) solution used in Mexico City Airport.
"Mexico City Airport wanted to upgrade it's information systems and provide flight infomation to their passengers throughout the airport. Contecnica was the vendor chosen to tackle this problem and the problem they were facing was the vast size of this airport. The airport spanned over 1 mile from gate 1 to gate 35. Sending identical video to over 50 locations spread out over a location of this size was a daunting task. Their previous system utilized a master PC which was updated by the flight controllers and 8 client PC's distributed throughout the aiport. Contecnica did not want to purchase 40+ PC's to act as clients to the master just to drive a video signal so we offered them a simpler and far less expensive solution. "
