Scan and video converters transform a digital computer image to a standard video signal for use with broadcasting or video devices such as televisions, monitors, or VCRs or vice versa. Scan and video converters allow equipment operating with differing video signal formats to be used together. A video format converter takes video and computer generated images and converts them to another output format or standard. For example, a video converter can convert composite video to 720p, SXGA (1280x1024) graphics to S-video, or mix 720p HD programming with 768p PC graphics. Video format converters are also known as seamless switchers, video scalers, and scan converters. A VGA to video converter converts video graphics array (VGA) red-green-blue-horizontal-vertical (RGBHV) video sources, which are color video signals used by computers and high definition video, to Y-Pr-Pb component video for use with high-definition televisions (HDTVs). Scan and video converters such as an S video converter separate color and brightness signals using a video signal, which separates luminance (Y) and chrominance (C) signals for displaying VHS or Beta ED images.
