Abstract
Systems and methods for providing compressed video with layered graphics to at least one screen are described herein. An On Screen Display (OSD) system receives a command from a remote set top box coupled to a screen. The command instructs the OSD system to process the input video stream according to various processing functions including layering at least one graphics plane on top of the video stream. The OSD system processes the input video stream to generate an output video stream with the layered graphics planes and outputs, in a compressed format, the output video stream to the screen. The system advantageously provides a central OSD processing unit that can output video with layered graphics in a compressed format to multiple displays.
