Abstract: A new video system and processor for computer is disclosed. In accordance to the present video processor that is capable of receiving TV signals and driving partial computer devices (such as a LCD panel) without starting the computer's operating system, the computer may display TV videos on the display panel of the computer without turning on the main power and the operating system. Furthermore, by returning the partial video processes to the CPU and VGA after the operating system is started, it may achieve the goals for displaying TV programs or working as a regular monitor when computer starts normally. The present video processor comprises an initial control unit, a data conversion unit, a panel drive, a memory control unit, a switch unit, a video compression unit, an I/O interface, and two selective modules.
