Video Scan Converter

The RGB/Videolink® 1690 video scan converter transforms computer graphics and other signals to broadcast standard video. Computer generated images can then be recorded, broadcast, displayed or transmitted using ordinary video equipment.


The unit offers NTSC/PAL composite video, S-Video (S-VHS, Hi-8) and component analog video (Betacam/MII) outputs. SMPTE 259M digital output is available as an option. State-of-the-art digital signal processing circuitry eliminates interlace flicker in the output image. Even thin horizontal lines appear stable. Multiple levels of filtering offer you the best choice between image sharpness and flicker elimination.


A zoom function lets you scale a portion of the image to emphasize or to provide just the right amount of underscan/overscan adjustment. The RGB/Videolink 1690 provides automatic synchronization to computer signals at up to 1600 x 1200 pixels, including virtually all desktop computers and workstations.


Professional quality scan conversion has never been easier.
