A Video Extender is used in places where there is a need to extend video between output device and the source over long distances. Different formats of extenders available today such as DVI, HDMI, VGA, KVM, composite and component extenders. The composite extender allows user to extend video signals beyond A/V rack and can cover a distance up to 1000feet.
DVI, Digital Visual Interface is specifically designed to provide high quality visual on devices with digital display such as digital projectors in auditoriums, conference rooms and flat LCD monitors. In other words, DVI is mainly designed for carrying uncompressed digital (video) data to a display. A DVI Extender is a mix of Analog and digital video interface. It does not carry any audio data like HDMI does in its TMDS channel.
This extender, using a single CAT5 cable can extend up to 500 feet and at the same time retain image quality. It supports video resolutions up till 1600 X 1200 @ 60Hz. For long distance DVI transmission fiber optic extender units are used. These extenders consist of a transmitter that is connected to a PC and a receiver that is connected to a monitor.
