How to distribute computer graphic signals over long distances?
There are three ways: The simplest way is to convert the computer graphics to video, and then use the video solutions for distant transmissions – by line amplifier, twisted pair or fiber optic. This approach needs a scan converter to convert DATA to video. This solution is simple but is limited by computer resolution. Resolutions of 640×480 can be used with this proposal with a minor loss of details (provided a high quality scan converter is used). The second way is to use either three very high quality video DAs for each of the Red, Green and Blue channels or a Component Video DA that amplifies all signals in parallel. In order to obtain the best results, take care to use the best available cables, as high resolution computer graphics signal quality deteriorates very rapidly when using inappropriate cables. Bear in mind that the computer graphics signal may come in various formats – RGB with sync riding on green (three channels), RGBS with separate syncs (four channels), RGBHsVs which
