Digitally-Encoded DVI / RGB
Video Transmission System |
|
| DESCRIPTION
Lascomm’s RGB product is part of Lascom’s DigiView™ product family. This state-of-the-art, cost-effective, high performance video transmission system transmits fully-compliant DVI, RGsB or RGBHV signals over one, multimode fi ber. The supplied adapters (dongles) allow easy interface to standard RGBHV connectors on computers and monitors. This RGB product provides real-time, digitized transmission of DVI, RGB and H&V sync signals. Because it transmits signals in realtime, no video information is lost and is a perfect solution for dynamic video signals with crystal clear video and no color pixel skewing. Having both DVI and RGB input capability, this system offers an easy upgrade path from RGB to DVI systems with the same modules. In addition, this dual format capability allows the user to convert from one format to the other (RGB to DVI, DVI to RGB) to ensure compatibility with a wide variety of video sources and monitors. An example of this would be to supply a RGB signal at one end of the link and output a DVI signal at the other end. The user can further enhance the video performance with the use of the computer USB interface. This data channel allows the user to adjust brightness, contrast, H&V position, picture sharpness, color, etc. As with all of Lascomm’s DigiView products, this unit has a 10-year warranty.
Note: Options available for Mouse, Keyboard and Audio
