FIG. 8 is a flowchart showing a processing procedure of the audio data reproducing function of the personal computer according to the embodiment of the present invention. Here, the operation knob 116a of the mode control switch 116 is operated to the left sliding position (PM). Then, the reproduction process of the CD / DVD is executed, and the mode control switch 116
Is operated to the right slide position (PD), the reproduction process of the digital sound data using the playlist 302 is executed.

FIG. 9 is a flowchart showing a processing procedure of the audio data reproducing function of the personal computer according to another embodiment of the present invention. In this case, when the mode control switch 116 is operated to any of the slide positions, Alternatively, when another hardware switch for instructing audio reproduction is pressed, a reproduction process of a sound source (CD / DVD / digital sound data) according to the registered contents of the playlist 302 is executed.

FIG. 10 is a diagram showing the flow of the reproduction processing in the above-described embodiment. When the mode control switch 116 is operated during the operation of the system, the switch operation manages the button operation from the BIOS via the OS. (Hereinafter referred to as an SMG program). SM
Upon receiving the above notification, the G program starts a player application program (CD player application / DVD player application / digital sound player application) to be played back in accordance with the operation of the switch.

More specifically, mode control switch 1
16 is operated, the switch operation state is changed to BIOS.
Is notified to the SMG program via the OS, and the SMG program inquires the BIOS about the contents of the switch operation (inquires about the switch operation event).
An instruction to reproduce a disk medium such as a CD / DVD (operation knob 116a is operated to the left slide position (PM)) or an instruction to reproduce digital sound data such as MP3 data (operation knob 116a is operated to the right slide position (PM) P
D) is recognized.

Here, if the instruction is to reproduce a disk medium such as a CD / DVD, it is determined whether or not the disk medium is being reproduced. If not, the digital sound player is performing a reproducing operation (digital sound). It is determined whether or not the playback process is being performed under the control of the player application program. If the playback operation is in progress, the operation is stopped and the disk drive (CD / DVD-DR) is controlled.
V) A CD player (CD player application program) or a DVD player (DV
(D player application program).

If the instruction is to reproduce digital sound data, it is determined whether the digital sound player is operating. If not, the digital sound player is loaded into the disk drive (CD / DVD-DRV) 21. It is determined whether or not the disc is being reproduced. If the disc is being reproduced, the operation is stopped and then the digital sound player application is started to be reproduced.

During the reproduction process after each player is started, the "reproduction stop" button, "forward" button, "reverse" button and the like included in the A / V control button 117 must be operated. Thus, playback stop, forward feed, reverse feed, and the like can be performed. Also, the bass boost button 118
By pressing down, the output volume level of the bass range from the subwoofer can be switched.

The operation of the embodiment of the present invention will now be described with reference to the above-mentioned drawings.

In the present invention, a reproduction operation according to a play list is started by a direct operation instruction by a hardware switch.

Here, a playlist 302 in which a plurality of pieces of information designating (specifying) digital sound data to be reproduced are registered in the order of reproduction is created in advance, and a hard disk drive (HDD) 210 is used to store a main memory (ROM / RA).
M) 202, so that the digital sound player (digital sound player application program) can be referred to.

In the above system operating state, the CD,
When instructing reproduction of a disk medium such as a DVD, the operation knob 116a of the mode control switch 116 is operated to the left slide position (PM). Also, MP
When instructing reproduction of digital sound data such as 3 data, the operation knob 1 of the mode control switch 116 is used.
16a is operated to the right slide position (PD).

By operating this mode control switch 116, the embedded circuit (EC)
From 209, an SMI according to the switch operation occurs,
The interrupt is notified to the CPU 201. On the software side, the BIOS sends O
An event indicating the slide operation of the mode control switch 116 is generated with respect to the SMG program via S, and the SMG program inquires the BIOS about the operation of the switch, thereby instructing the reproduction of the disk medium such as a CD / DVD (operation). The knob 116a is operated to the left sliding position (PM), or an instruction to reproduce digital sound data such as MP3 data (operation knob 116a).
Is operated to the right slide position (PD)) (step A11 in FIG. 8).

Here, if the instruction is to reproduce a disk medium such as a CD / DVD, it is determined whether or not the disk medium is being reproduced. If not, the digital sound player is performing a reproducing operation (digital sound). It is determined whether or not the reproduction process is being performed under the control of the player application program. If the reproduction operation is being performed, the operation is stopped (see FIG. 10 (4-1)), and the disc drive (CD / DVD- In response to the determination of the mounted reproduction medium recognized by the controller side of the DRV) 21, the reproduction is started on the CD player (CD player application program) or the DVD player (DVD player application program) (FIG. 8, steps A12 to A12).
A14) (see FIG. 10 (5-1)).

If the instruction is to reproduce digital sound data, it is determined whether the digital sound player is performing a reproducing operation. If not, the digital sound player is loaded into the disk drive (CD / DVD-DRV) 21. It is determined whether or not the disc has been reproduced. If the disc is being reproduced, the operation is stopped (see FIG. 10 (4-2)), and then the disc is stored in the above-described register area at the time of the previous termination. The reproduction target data is selected from the playlist 302 using the information (FIG. 8).
Step A15), the reproduction start of the digital sound player (digital sound player application program) is performed (step A16 in FIG. 8) (see FIG.
2)).
