Steps.

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

1 is a schematic block diagram of a typical optical disc changer system for practicing the present invention.

As shown in FIG. 1, an optical disc changer system 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, the microcomputer 50, the digital signal processor 60, the MPEG decoder 70, the audio signal processor 80, the video signal processor 90, the speaker 100, and the screen 110.

The pickup and actuator unit 10 executes an optical pickup from one of the loaded discs to reproduce data among the discs mounted on a disc tray (not shown) capable of mounting a plurality of discs, thereby reading out an RF signal. Outputs

In addition, the motor driving unit 30 drives a 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 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 can be 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 MEPG decoder 70 and output them to the speaker 100 and the screen 110, respectively. ) And the screen 110 are displayed as an audio transmission and an image, respectively. On the other hand, according to the present invention, when the memory stop key signal is input from the key input unit 40 while the reproduction is performed in the above-described manner, the microcomputer 50 accordingly provides the Q provided from the digital signal processing unit 60. By referring to the data, the time information of the storage position to which the storage stop key signal is input and the table of content (TOC) information of the disc currently being played are stored in a built-in memory (not shown) by designating a predetermined address. 50 stores these stored information data in a memory in a format as shown in FIG.

In Fig. 5, data (1, 2, 3) representing the type of disc can be set to data representing CD, VCD1.1, and VCD2.0, respectively.

After storing the stored information data according to the storage stop key signal for storing and reproducing the above process, if a predetermined disc is loaded in the disc tray, the microcomputer 50 reads the TOC information of the loaded disc, By comparing with the TOC information data, it is determined whether the storage information data for the loaded disk is already stored. At this time, if the memory information data for the loaded disc is already stored in the memory, the microcomputer 50 reads the memory information data and provides the same to the video signal processor 90, and the video signal processor 90 processes the text. The display 110 outputs the image to the screen 110 so that the user can recognize it by displaying it. FIG. 3 shows an example of data displayed on the screen 110.

On the other hand, if the storage information data for the loaded disc is not already stored in the memory, that is, if the storage stop for the memory reproduction has not been executed for the loaded disc, the microcomputer 50 stores the memory from the key input unit 40. Detects whether a memory information confirmation key signal is input for displaying and confirming all other memory information data stored in the memory. When the memory information confirmation key signal is input, the microcomputer 50 reads out all the memory information data stored in the memory and sequentially Provided to the video signal processor 90, the video signal processor 90 processes the text and outputs it to the screen 110, the screen 110 displays them sequentially so that the user recognizes them.

That is, as shown in Fig. 4, the storage position information includes the type of the disc, the total track of the disc, the total playback time, the track number of the position where the storage position data is stored, the time information for the storage position, and the storage date. As shown in FIG. 5, the data may be displayed on the screen 110 based on the data stored in the memory.

2 is a flowchart of a storage information processing method in an optical disc changer system according to a preferred embodiment of the present invention.

When the playback key signal is input in step S10 and playback is performed, it is determined in step S20 whether the storage stop key signal is input. When the storage stop key signal is input in step S20, the flow advances to step S30. In step S30, the positional information on the playback position at the time when the storage stop key signal is input, i. In this case, the TOC information of the disk on which the storage stop has been executed is stored at the same address where the storage position information is stored. In step S40, the optical disk changer system is set to the standby mode.

Thereafter, in step S50, it is determined whether a predetermined disk is loaded from the disk tray. At this time, if it is determined that the disk has been loaded, the process proceeds to step S60; otherwise, the process proceeds to step S90.

First, when the process proceeds from step S50 to step S60, in step S60, the TOC information of the loaded disk is read and stored, and in step S70, the TOC data of the loaded disk read out in step S50 is stored. In step S30, the TOC data stored together with the storage position data are compared to determine whether they are the same to detect whether the disk loaded in step S50 has previously executed a memory stop.

In step S70, if predetermined storage stop data for the loaded disc is detected, the flow advances to step S80 to display the storage information data as shown in FIG. 3, and then proceeds to step S90. If no, go directly to step S90.

Then, in step S90, it is determined whether or not a storage information confirmation key signal for confirming all previously stored storage information other than the storage information data displayed in step S80 is input, wherein the storage information confirmation key signal is inputted. If the flow proceeds to step S100, all other stored information data is displayed in the form as shown in FIG. 4, and then the flow ends. Otherwise, the flow ends immediately.

Therefore, the present invention has the advantage of enabling the memory reproducing to be performed more conveniently because the information on the storage position and the respective discs can be checked in advance when the memory reproducing is to be executed in the optical disc changer system.
