As shown in FIG. 1, an optical disc player for implementing the present invention includes a pickup and actuator unit 10, an RF (radio frequency) signal amplification and servo signal processor 20, a motor driver 30, and a key input unit 40. ), A microcomputer 50, a digital signal processor 60, an MPEG decoder 70, an audio signal processor 80, a video signal processor 90, a speaker 100, and a screen 110.

The pickup and actuator unit 10 executes an optical pickup from a disc loaded in a disc tray (not shown) and outputs an RF signal which is read accordingly.

In addition, the motor driving unit 30 drives the spindle motor (not shown) to rotate the disk, and drives the actuator unit 10 so that the pickup unit 10 performs optical pickup to read the data recorded on the disk to RF Output as a signal.

The RF signal amplification and servo signal processing unit 20 amplifies an RF signal provided from the pickup and actuator unit 10 and provides a servo control signal according to the signal to the motor driving unit so that the focus servo and the tracking servo are performed.

The digital signal processing unit 60 digitally processes the amplified RF signal provided from the RF signal amplification and servo signal processing unit 20, performs error detection and error correction, and outputs the result to the MPEG decoder 70.

The MPEG decoder 70 decodes an error corrected digital video signal and an audio signal provided from the digital signal processor 60 based on the MPEG compression format and outputs the decoded video signal to the video signal processor 90 and the audio signal processor 80. .

The audio signal processing unit 80 and the video signal processing unit 90 process the decoded audio and video signals provided from the MPEG decoder 70 and output them to the speaker 100 and the screen 110, respectively. And the screen 110 are displayed as an audio and an image, respectively.

According to the present invention, on the other hand, data which enables to sequentially or selectively perform all the functions that are characteristic of the optical disc player, for example, a playback control function, a karaoke function, repeat playback, image search, memory playback, and the like, are recorded. When the test disc is loaded in the disc tray, the microcomputer 50 generates a control signal to the motor driver 30, and accordingly, the motor driver 30 is driven to drive the pickup and actuator part 10, thereby picking up and actuator part. 10 reads and outputs TOC (table of contents) data from the test disk, and the microcomputer 50 stores it in an internal memory (not shown).

Thereafter, when the test mode key signal is input from the key input unit 40, the microcomputer 50 accordingly stores data and control signals for the functions recorded on the test disc with reference to the stored TOC data to the video signal processing unit 90. As a result, the video signal processor 90 processes OSD (on screen display) data provided from the microcomputer 50 to the screen 110, and the screen 110 displays the text as text to display the text. A function selection key signal for executing a predetermined function is input.
