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

The city council of Huntington Beach, CA uses a Hall Research Video Solution and custom voting application.
"A few years ago, the city council of Huntington Beach came to Hall Research asking for a solution for their video presentation in their public meeting chambers. The problem was they wanted citizens to have the ability to show a presentation on a PC, that would be displayed by a large projector, but they could not have the PC in the meeting chambers. "
