Abstract
A video processing system is provided. A video signal processor receives a video signal, processes the video signal to obtain video images and program information and stores the program information in a program information buffer. A microprocessor issues an on screen display (OSD) paint command and accesses the program information buffer to obtain the program information. An OSD control module receives the OSD paint command and acquires the program information from the microprocessor, and converts the program information and initial attributes to form an OSD image in response to the OSD paint command.
