Embodiment Construction

[0027] Please refer to FIG. 1. FIG. 1 illustrates a functional block diagram of a conventional computer system 10. The computer system 10 includes a computer 20 and a medium device 30 for accessing storage medium. The computer 20 includes a central processing unit (CPU) 12, a memory 14, a display unit 32, a chipset 40, loudspeaker 28 and a control interface 26. The CPU 12 is capable of executing programs and algorithmic calculations, processing data, and controlling the main operation of the computer system 10; the memory 14 is utilized for temporarily storing program codes, data, and figures required by the CPU 12 during operation. The display unit 32 is utilized for displaying graphic pictures, and the loudspeaker 28 broadcasts sound. The control interface 26 is then utilized for receiving control operations of a user such as a keyboard, a mouse, a touch pad, or other indicating devices. The medium device 30 acts as a peripheral of the computer system 10 and is coupled to the chip...

Abstract

A multimedia computer system and method is disclosed. A medium device of the computer system, like an optical disc loader, has a built-in function of multimedia decoding for supporting the computer system to work under a normal mode and a playback mode. In the normal mode, the medium device does not decode, and north / south bridges of the computer arrange data exchange and access between the medium device, a CPU, and a memory of the computer system. In the playback mode, the medium device performs multimedia decoding itself for obtaining video data from the medium, and the video data are sent to a display of the computer system by the north bridge. Therefore, in this playback mode, other circuits like the south bridge, CPU and memory can be powered down to an idle status, and a low power consumption multimedia broadcast is realized.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 630,533, filed Nov. 22, 2004, and included herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a multimedia computer system and method, and more particularly, to a multimedia computer system and method capable of supporting a low power consumption multimedia playback mode.
