Video system and processor for computer

A video processor, which applies to a VGA-included computer system for playing TV programs on a display panel without booting the computer's operating system, said video processor comprises:

• an initial control unit for handling relevant computer devices;
• a data conversion unit for converting input TV video data into computer video data;
• a panel drive for generating a driving signal in LVDS format;
• a memory control unit for controlling an external memory to access data;
• a data exchange interface, wherein said data conversion unit, said memory control unit, and said panel drive exchanges data through said data exchange interface;
• a first selective module including:
• an input port for receiving the input TV video data;
• a first output port electrically coupling with said data conversion unit;
• a second output port electrically coupling with the VGA, wherein said first selective module outputs said TV video data selectively through said first output port or said second output port;
• a second selective module including:
• a first input port electrically coupling with said panel drive;
• a second input port electrically coupling with the VGA;
• an output port electrically coupling with a display panel, wherein said second selective module selects said first input port or said second input port to output to said display panel;
• and
• a switch unit for receiving a mode switch order to select an effective input port or an effective output port of said second selective module and an effective output port of said first selective module.

A video processor, which applies to a VGA-excluded computer system for playing TV programs on a display panel without booting the computer's operating system, said video processor comprises:

• an initial control unit for handling relevant computer devices;
• a data conversion unit for converting input TV video data into computer video data;
• a panel drive for generating a driving signal in LVDS format;
• a memory control unit for controlling an external memory to access data;
• a video compression unit for compressing said computer video signals into compressed video data;
• a data exchange interface, wherein said data conversion unit, said memory control unit, said video compression unit, and said panel drive exchanges data through said data exchange interface;
• a selective module including a first input port electrically coupling with said panel drive, a second input port electrically coupling with a north bridge chipset, and an output port electrically coupling with a display panel, wherein said selective module selects an effective input port to output to the display panel;
• and
• a switch unit for receiving a mode switch order to select an effective input port of said selective module.

A computer video system capable of playing TV programs on a display panel without booting the computer's operating system, said computer video system comprises:

• a core module including a CPU, a memory, a south bridge chipset, and a north bridge chipset for computing data;
• a display panel for displaying videos;
• and
• a video processor, wherein said video processor receives TV video data and processes a TV/computer signal conversion to generate a first panel driving signal, or receives a second panel driving signal of LVDS format generated by the core module to output to the display panel.
