Computer system and method for reproducing audio file

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system and a method for reproducing an audio file thereof. More particularly, a computer system and a method for reproducing an audio file can be reproduced easily without driving hardware unnecessary for reproducing the audio file in the system. It is about.

Due to the development of the multimedia functions of the computer and the development of the Internet, the number of users who listen to music and movies using the computer is increasing rapidly. In particular, music played through a computer is of high quality, and the size of a music file is not so large, so it is widely spread. Most music files are produced by reading and converting music from compact discs. Generally, such music files are called audio files.

The audio file can be easily obtained in communication, and a performance program to be played back can also be easily obtained in communication. Representative audio files include mp3, wav, ra, and midi files. Among them, the most widely used audio files are MP3 files with high sound quality compared to the file size. Mp3 files are not only computers but also dedicated players, and the demand is increasing exponentially.

In order to play audio files stored on a hard disk drive or audio files stored on a medium such as a compact disc, ROMBIOS must run a post-routine to boot the system's operating system. However, the system's booting time becomes longer because the post-routine executed by ROMBios has to go through the process of checking hardware, including memory test, graphic initialization, and monitor, which are unnecessary to play audio files. Therefore, when using such a method, there is a problem that the power consumption is increased and the lifespan of hardware is shortened by driving unnecessary equipment.

In the case of playing an audio file by embedding an MP3 player in the computer system, the computer system has an advantage of playing an audio file without executing a post-routine. However, when using this method, a separate MP3 player must be embedded in the computer system, and audio files stored in an auxiliary memory device such as a hard disk drive cannot be reproduced.

Accordingly, an object of the present invention is to provide a computer system capable of minimizing power consumption and lifespan without driving unnecessary hardware of the system when the computer is driven only for the purpose of listening to music.

The audio file information window 17 is formed on one side of the audio reproduction selecting section 11.

The audio reproduction selection unit 11 and the audio file information window 17 are provided in one region in front of the casing 10, and the audio power button 13 is connected to the power supply unit 60 and the ROM bios 50. Accordingly, when the audio power button 13 is selected, the power supply unit 60 supplies power to the ROMBIOS 50, the controller 25, the CD-ROM drive 40, and the sound card, and the controller 25 supplies the audio power. It detects that the button 13 is selected to execute the second post routine and to execute the decoding program 55.

On the other hand, since the monitor 2 does not operate when the audio file information window 17 is driven, the audio file information window 17 transmits text information about the audio file to the user through the LCD screen instead of the monitor 3. It is for. The audio file information window 17 is connected to the main board 20 to receive power from the power supply unit 60, and receives and outputs data from the central processing unit 21.

On the other hand, the front of the casing 10 is provided with a power switch 18 for supplying power to the system and a reset key 19 for rebooting the system without checking the memory. Here, the power switch 18 is provided with a casing. It is connected by the power supply unit 60 and the main board 20 provided in (10) to apply power to the system.

A process of playing an audio file in the computer system having such a configuration will be described below with reference to FIG.

First, a power source for driving the system should be applied to the system. As described above, power is supplied to the system by the audio power button 13 and by the power switch 18. There are two things when power is applied.

Accordingly, the controller 25 detects whether the audio power button 13 or the power switch 18 is selected. When the audio power button 13 is selected (S10), the power supply unit 60 supplies power to the ROMBIOS 50, the control unit 25, the CD-ROM drive 40 (S20), the ROM 25 in the control unit 25 The second postroutine of the bios 50 is called (S30). When the second post-routine is executed, it is checked whether hardware such as the sound card 23 and the CD-ROM drive 40 necessary for audio reproduction are mounted. If each hardware is mounted, each hardware is driven.

When the hardware is driven, the central processing unit displays the driving of the hardware through the audio file information window 17, and the user selects the audio play button 15 to play the audio files (MP3 file, RA file, WAV file, etc.). Choose. Then, the controller 25 operates the CD-ROM drive 40 and operates the decoding program 55 in the ROMBIOS 50 to convert the audio file stored in the compact disc into a digital signal from an analog signal (S40). In this case, the decoding program 55 may be automatically operated without the audio play button 15 being selected. On the other hand, the decoded audio file is delivered to the sound card, the audio signal is amplified in the sound card and output through the speaker 65 (S50, S60). During playback of such an audio file, text information is continuously output through the audio file information window 17.

When the power switch 18 is selected in step S10 (S15), the power supply unit 60 supplies power to each hardware (S25), the control unit 25 calls the first post routine of the rombios (50) (S35).
