Engineering:VGA box

A VGA box is a video converter that converts common analog video standards such as S-Video and component video to VGA format. Some VGA boxes include audio outputs for connecting to computer speakers. Others models include devices that convert VGA signals to composite, S-video, or component video, as well as SCART in Europe. A VGA-to-HDMI converter digitizes incoming analog VGA signals and upscales to HDTV resolutions to enable a VGA video source to be displayed on an HDMI connection. The scaling engine ensures the VGA output fits the full HDTV screen with no image shifting or alignment issues.
