The data storage unit 350 stores help data for each of the function keys and the numeric keys provided in the key input unit 110 of the optical disc player 100. In this case, the help data is spoken through the speaker 400. It will be stored as sound source data for output.

The voice signal processor 360 converts the help data drawn from the data storage 350 into a voice signal and provides the voice signal to the speaker 400 under the control of the PC controller 310, and the speaker 400 provides a key input unit. Help for the key signal generated at 110 is output as a voice.

Hereinafter, a method for providing help of an optical disc player according to the present invention, which is implemented in the apparatus for providing help of an optical disc player including the above-described members, will be described with reference to FIG.

2 is a detailed flowchart illustrating a method for providing help of an optical disc player according to the present invention.

First, when the PC is powered on (S 1), when the user presses a help setting key provided in the key input unit 110 to refer to the help of the optical disc player, the key input unit 110 may help. The set key signal is provided to the optical disc player controller 120 (S 2).

The optical disc player controller 120 receiving the help setting key signal from the key input unit 110 generates a reception request signal and provides the received request signal to the optical disc player connector 210 (S 3).

In S 3, the reception request signal generated by the optical disc player controller 120 is provided to the optical disc player connector 210, and the optical disc player connector 210 provides it to the PC connector 220 again.

The PC connector 220 provides the serial port controller 230 with a reception request signal provided from the optical disk player connector 210.

When the reception request signal is input from the PC connector 220, the serial port controller 230 generates an interrupt signal to the PC controller 310 (S 4).

By the interrupt signal generated by the serial port controller 230, the PC controller 230 stops controlling the general operation of the working PC and prepares to receive data from the serial connection unit 200 (S 5).

The serial port controller 230 checks the state of the PC controller 310 and applies a receivable signal to the optical disk player controller 120 through the PC connector 220 and the optical disk player connector 210 (S6).

The optical disc player controller 120 receiving the receivable signal from the serial port controller 230 recognizes that the PC 300 is in a receivable state, and provides key codes 8 corresponding to the help setting key signal to the optical disc player connector 210. Provided as serial data in bits.

The optical disc player connector 210 provides 8-bit serial data corresponding to the help setting key code provided from the optical disc player control unit 120 to the PC connector 220, and the PC connector 220 returns this to the serial port control unit. Provided to (230). (S 7)

The serial port controller 230 converts the 8-bit serial data of the help setting key code provided through the optical disc player connector 210 and the PC connector 220 to provide it to the PC controller 310 (S 8).

The PC control unit 310 will detect the function corresponding to the help setting key code with reference to the PC code storage unit 320, and as a result, the PC control unit 330 will connect the optical disc player (e.g., via the serial connection unit 200). It will be recognized that the data transmitted in 100) is the help setting key code.

Therefore, the PC control unit 310 switches to the help mode, so that all data transmitted from the optical disc player 100 will be referred to by the optical disc player code storage unit 340 (S 9).

Thereafter, when a predetermined key signal is generated in the key input unit 110 by a user's key manipulation, the generated key signal is provided to the optical disc player controller 120. (S 10)

The optical disc player controller 120 receiving the key signal from the key input unit 110 provides a key code corresponding to the key signal to the PC connector 220 as 8-bit serial data, which is again supplied by the PC connector 220. Provided to the serial port controller 230. (S 11)

The serial port controller 230 provides 8-bit data of the help setting key code provided through the optical disk player connector 210 and the PC connector 220 to the PC controller 310 (S 12).

The PC controller 310 searches for the function of 8-bit data provided from the serial port controller 230 with reference to the optical disc player code storage unit 330 (S 13), and stores an address corresponding to the retrieved function in the address unit ( 340 is taken out (S14). In this case, the address indicates a predetermined position of the data storage unit 350 and is referred to when storing or reading data in a predetermined section of the data storage unit 350.

Thereafter, the PC controller 310 refers to the address detected by the address unit 340, and extracts the help data stored in the predetermined position of the data storage unit 350. (S 15) At this time, the help data is an optical disc. The sound source data for the help corresponding to each of the function keys and the numeric keys provided in the key input unit 110 of the player 100 will be described.

In step S15, the PC controller 310 controls the voice signal processor 360 to output the help data drawn from the data storage 350 as a voice.

The voice signal processor 360 converts the help data converted into the sound source data into the voice under the control of the PC controller 310 and provides it to the speaker 400 (S 16).

Therefore, in the speaker 400, the help corresponding to the key signal generated by the optical disc player key input unit 110 will be output as voice.

As described above, according to the present invention, since the key signal generated from the key input unit is provided to the PC as serial data to control the operation of the optical disc player, help for various functions provided by the optical disc player is transmitted through the speaker of the PC. It can be described, so that the user can easily understand and utilize the functions provided by the optical disc player.
