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.
Claims18
A video processing system, comprising:
- a video signal processor, receiving a video signal, processing the video signal to obtain a plurality of video images and program information, and storing the program information in a program information buffer;
- a microprocessor, issuing an on screen display (OSD) paint command and accessing the program information buffer to obtain the program information;
- and
- an OSD control module, receiving the OSD paint command and acquiring the program information from the microprocessor, and converting the program information and a plurality of initial attributes to form an OSD image in response to the OSD paint command.
A video processing method for a video processing system comprising a program information buffer, comprising:
- receiving a video signal and processing the video signal to obtain a plurality of video images and program information;
- storing the program information in the program information buffer;
- issuing an on screen display (OSD) paint command to begin painting an OSD image;
- acquiring the program information from the program information buffer in response to the OSD paint command;
- and
- generating the OSD image according to the program information and a plurality of initial attributes.
A video processing system, comprising:
- a video signal processor, comprising a program information buffer, receiving a video signal, processing the video signal to obtain a plurality of video images and program information, and storing the program information in the program information buffer;
- and
- an on screen display (OSD) control module, receiving an OSD paint command, and acquiring the program information from the program information buffer and converting the program information and a plurality of initial attributes to form an OSD image in response to the OSD paint command.
