Description

Method of processing disc content information in an optical disc player

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc player, and more particularly, to a disc content information processing method of an optical disc player, which is recorded on an optical disc and appropriately processes disc content information for reference in executing an optical disc player .

A typical optical disc reproducing apparatus includes a compact disc player (CDP), a laser disc player (LDP) and a compact disc graphic player (CDGP), a video compact disc player (VCDP: a compact disc player, a compact disc player, and a video compact disc player are devices capable of reproducing video and audio at the same time .

In recent years, a digital video disk (DVD) using MPEG-2 moving picture compression technology has been developed. This is because a gigabyte (GB) capacity Data can be recorded and reproduced, and the performance is continuously being improved to improve the performance.

The optical disk reproducing apparatus reproduces the video and / or audio recorded on the optical disk and outputs the reproduced video and / or audio through the screen and / or the speaker. The optical disk reproducing apparatus has a higher signal- It is possible to reproduce a signal with image quality and / or sound quality, to generate no noise due to irregular reproduction and modulation, to have very few distortion, to have no ghost, and to have random access, And it is in a trend of spreading widely.

In order to perform various functions such as reproducing data recorded on an optical disc in such an optical disc player, in general, disc content information recorded in a lead-in area of the optical disc, that is, a total content ) Information should be read and stored first when the disc is loaded and then referenced.

The TOC information is information of the disc when the disc tray is opened and the disc tray is closed after the disc is loaded and the disc tray is loaded and loaded among the components constituting the optical disc player. And is stored in the memory.

Then, when a predetermined function key signal is provided, the optical disc player refers to the stored TOC information and performs various functions according to the inputted key signal such as reproduction, search, and the like.

Meanwhile, as described above, the TOC information read out at the initial stage of disk loading in the optical disk player and stored in the memory is automatically read and stored when the disk tray is closed after the disk is loaded in the disk tray, It disappears automatically. That is, when the user opens the disc tray to replace the disc, the TOC information of the previously stored disc is all consumed.

However, when the user opens the disc tray while using the optical disc player, the disc tray may be opened for confirming the disc, not for exchanging the disc. In addition, In this case, the pre-stored TOC information is cleared at the moment when the disc tray open key is input, and then the disc tray is re-opened again. The same TOC information must be read out and stored again on the same disc, so that the speed of realizing a predetermined function has been disadvantageously lowered.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide an optical disc apparatus, And to provide a method of processing disc content information in an optical disc player capable of speeding up a function implementation speed of a player.

According to an exemplary embodiment of the present invention, there is provided a method of recording data in a lead-in area of an optical disc, The method comprising the steps of: (a) performing an open operation of the disc tray when a disc tray open key signal having the disc loaded therein is input during a predetermined function or in a standby state, (B) if the opening of the disc tray is completed in the step (a), after storing the previously stored TOC information, if the disc tray is closed, Reading and storing the TOC information of the loaded disc if the disc is loaded, (c) If a predetermined function key signal is inputted in the state where the disc tray is being opened in the step of performing the close operation of the disc tray, it is determined whether there is already stored TOC information, and if there is already stored TOC information, And reading and storing the TOC information if there is no pre-stored TOC information, and executing an operation according to the inputted predetermined function key signal.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of an optical disc player for carrying out the present invention.

1, an optical disc player for carrying out the present invention includes a pickup and actuator unit 10, a radio frequency (RF) signal amplification and servo signal processing unit 20, a motor driving unit 30, a key input unit 40, a microcomputer 50, a digital signal processing unit 60, an MPEG decoder 70, an audio signal processing unit 80, a video signal processing unit 90, a speaker 100 and a screen 110.

The pickup and actuator section 10 executes an optical pickup from a disk loaded in a disk tray (not shown) and outputs an RF signal thus read out.

The motor driving unit 30 drives a spindle motor (not shown) to rotate the disc and actuate the actuator unit 10 so that the pickup unit 10 executes the optical pickup to read the data recorded on the disc, Signal.

The RF signal amplification and servo signal processing section 20 amplifies the RF signal provided from the pickup and actuator section 10 and also provides a servo control signal according to the signal to the motor driving section so as to perform focus servo and tracking servo.

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

The MPEG decoder 70 decodes the error corrected digital video signal and the audio signal provided from the digital signal processing unit 60 based on the MPEG compression format and outputs the decoded digital video signal and audio signal to the video signal processing unit 90 and the audio signal processing unit 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 respectively outputted as a voice and displayed as an image.

According to the present invention, when the disc tray open key signal is inputted by the user through the key input unit 40 in the state where the optical disc player executes a predetermined function or in a standby state, the microcomputer 50 transmits the control signal And drives the motor driving unit 30 to rotate the tray driving motor (not shown) to open the disc tray. At this time, when the optical disc player is in the standby state, the disc tray is controlled to be opened immediately The control unit controls the disk tray to perform an open function after switching to the standby mode by stopping the operation being performed first when the predetermined function is being performed.

The microcomputer 50 detects whether a predetermined key signal is input from the key input unit 40 until the opening of the disc tray is completed by performing the opening process of the disc tray. When a predetermined key signal is input before the opening of the disc tray is completed, the microcomputer 50 generates a control signal to the motor driving unit 30 to close the disc tray after stopping the opening of the disc tray. When the disk tray is closed, the microcomputer 50 checks the internal memory (not shown) to determine whether there is TOC information already stored in the internal memory. At this time, the microcomputer 50 reads TOC information previously stored in the memory The TOC information of the disk mounted on the disk tray is read out if there is no pre-stored TOC information, and the TOC information of the disk mounted on the disk tray is read out And after storing the TOC information, generates a control signal by referring to the TOC information, thereby performing an operation according to the inputted function key signal.

Meanwhile, when opening of the disc tray is completed without inputting any other function key signal during the opening operation of the disc tray, the microcomputer 50 first clears the TOC information stored in the internal memory.

Thereafter, when a disc tray close key signal is input from the key input unit 40, a control signal is generated by the motor driving unit 30 to drive the tray motor to close the disc tray. When the disc tray is closed, If the disc is mounted, the TOC information of the disc is read and stored in the memory.

FIG. 2 is a detailed flowchart of a method of processing disc content information in an optical disc player according to a preferred embodiment of the present invention.

First, in step S10, it is determined whether a disc tray open key signal is input. At this time, if the disk tray open key signal is input, the process proceeds to step S20, and if not, the flow is fed back.

When the process proceeds from step S10 to step S20, the disk tray is opened in step S20, and in step S30, it is determined whether the disk tray is opened.

If the disk tray is opened in step S30, the process proceeds to step S40, and if not completed, the process proceeds to step S80.

In step S30, if it is determined in step S80 that a predetermined function key signal such as tray close, playback, or power off is input in step S80, S90). If not, the flow returns to step S20 to re-execute the flow.

When the process proceeds from step S80 to step S90, a closing operation of the disk tray is performed regardless of the key signal inputted in step S80 in step S90. If the disk tray is closed in step S90, it is determined in step S100 whether pre-stored TOC information exists. If YES in step S90, the flow advances to step S120. If there is no pre-stored TOC information, ).

When the process proceeds from step S100 to step S110, the TOC information of the disc mounted on the disc tray is read and stored in step S110, and then the process proceeds to step S120. In step S120, And performs an operation according to the inputted function key signal. When step S120 is completed, the flow ends.

On the other hand, when the disc tray is opened in step S30 and the process proceeds to step S40, the previously stored TOC information is cleared in step S40, and the process proceeds to step S50. Thereafter, in step S50, when the disc tray close key signal is inputted, it is determined whether or not the disc tray opened in step S30 is closed. At this time, if the disc tray is closed, the process proceeds to step S60.

If the disc tray is closed in step S50 and the process proceeds to step S60, it is determined in step S60 whether a disc is loaded in the disc tray. If the disc is mounted on the disc tray in step S60, the flow immediately ends. If the disc is loaded in the disc tray, the process proceeds to step S70, where the TOC information of the loaded disc is read and stored, and the flow ends.

Therefore, the present invention clears pre-stored TOC information only when the disk tray open key signal is inputted and the disk tray is opened, so that the function according to the function key signal inputted later can be executed more quickly have.
