Video processing apparatus and computer system integrated with the same

A computer system, comprising:

• a video decoder, which receives a video signal and decodes it to generate a digital video signal;
• a deinterlacer, which receives the digital video signal to generate a non-interlacing signal;
• a computer, which sends out a PIP command;
• a display;
• a PIP module, which receives the non-interlacing signal and a PIP characteristic signal and overlaps the non-interlacing signal with a screen signal in response to the PIP characteristic signal, producing a PIP video for the display to play;
• wherein the PIP characteristic signal controls the location and size of the PIP video and the screen signal is the background of the computer operating system (OS);
• and
• a PIP characteristic controller, which receives a PIP command, coming from a computer, to output the PIP characteristic signal according to the PIP command;
• wherein the deinterlacer and the PIP module are implemented by hardware.

A video processing apparatus, comprising:

• a video decoder, which receives a video signal and decodes it to generate a digital video signal;
• a deinterlacer, which receives the digital video signal to generate a non-interlacing signal;
• and
• a bridge, which converts the non-interlacing signal into a computer video signal that is compliant with a universal computer interface format;
• wherein the computer video signal is received by a computer and played on a display.
