Multimedia Computer System and Method
First Claim
1. A computer system capable of broadcasting multimedia data, the computer system comprising:
- a medium device comprises a front-end and a back-end, wherein the front-end is utilized for accessing multimedia data from a storage medium, and the back-end is utilized for decoding a corresponding image data from the multimedia data if the multimedia data from the storage medium accessed by the front-end is compliant to a preset multimedia format; and
a chipset coupled to the medium device for transmitting the image data obtained from decoding by the back-end to a display unit for displaying when the computer system operates in a default playback mode.

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.
