Abstract
The present invention provides an on-screen graphics (OSD) subsystem for overlaying OSD graphic images onto analog or digital video source signals. The OSD system has a video graphics bypass path and graphics bypass switch for directing an analog video channel around the OSD subsystem during time intervals when the OSD subsystem is not required to insert graphics into the source signal.
