BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repeat play method in an optical disc player, and more particularly, to a repeat play method of an optical disc player suitable for performing repeat play by correcting the end position of a set section in executing the repeat play.

With the development of audio and video media, optical disc players have been developed for recording and reproducing video and audio data on semi-permanent optical discs.

Such an optical disc player reproduces an image and / or audio recorded on an optical disc and outputs it through a screen and / or a speaker, and has a higher signal-to-noise ratio than conventional image and / or audio reproducing apparatus, resulting in better image quality and / or Or it can reproduce signals with sound quality, generate no noise due to irregular reproduction and modulation, very low distortion, no ghost, random access, etc. There is a trend.

In addition, such optical disk players include compact disk players (CDPs), laser disk players (LDPs), compact disk graphic players (CDGPs), and video compact disk players (VCDPs). video compact disk player) has been developed and widely used, and recently, a digital video disk (DVD) using MPEG-2 moving picture compression technology and a digital video disk player for playing the same have been developed. It can record and play back gigabytes (GB) of data including moving pictures on a 12cm optical disc such as a CD, and it is also made to be compatible to play current CDs and VCDs.

On the other hand, in a typical optical disc player, if a user wants to repeatedly play a specific section that he / she wants, a series of processes such as searching for a section and playing a disk at the corresponding position by manual operation must be repeated as many times as the number of plays. There was discomfort.

Accordingly, the present invention has been devised in view of the above-described point, and it is possible to repeat a section by setting a desired section when the disc is played in the optical disc player, and repeat the section of the optical disc player which can modify the end point of the set section. The purpose is to provide a regeneration method.

In order to achieve the above object, the present invention provides a menu screen for setting the repetition section when a repetition section setting signal for section repetition playback is input during normal play of a disc, and displays a starting point for the repetition section ( A first step of receiving and storing the repetition section setting information including P1), the end point P2, and the number of repetitions C1, and if a reproduction signal for the set repetition section is input, repeating based on the stored repetition section setting information Reproducing the disc at the interval starting point P1, and counting up the number of times of the playback C2; when the disc playback position of the disc reaches the end point P2 of the set repeating period, A third step of checking whether the end point P2 of the set repeating section is changed after the disk play operation is paused, and the end point P2 of the repeating section; A fourth step of changing / updating the set end point P2 when the change information is input, and comparing the counted number of times of play C2 with the set number of times of repeat play C1 and matching the repeated section play process. And a fifth step of repeating the process after the second step if the disc is not normally played, if the disc does not match.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

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

1 is a block diagram of an optical disc player suitable for performing a repetitive playback method according to the present invention, which includes a deck unit 10, an optical pickup unit 20, a digital signal processor 30, a microcomputer 40, The key input unit 50, the MPEG decoder 60, the memory unit 70, the audio signal processor 80, the video signal processor 90, and the OSD unit 100 are included.

The optical pickup unit 20 chucks the disk mounted on the deck unit 10 based on a control signal for the optical pickup generated from the microcomputer 40, and performs optical pickup from the chucked disk. The signal is read, with the table's table of content (TOC) information also read.

The read RF signal is provided to the digital signal processor 30, and the digital signal processor 30 outputs the RF signal to the MPEG decoder 60 after digital signal processing, error detection and correction.

The MPEG decoder 60 decodes an error corrected digital video signal and an audio signal provided from the digital signal processor 30 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 processor 80 and the video signal processor 90 process the decoded audio and video signals provided from the MPEG decoder 70 and output them to a speaker (not shown) and a monitor (not shown), respectively.

In the optical disc player configured as described above, when the user sets the desired section during disc playback and inputs the section setting start key signal through the repeat play key input unit 50 as many times as desired, the microcomputer 40 displays the OSD unit. An OSD driving signal is generated at 100 to display a menu screen for repetition interval setting.

When the user inputs the start point of the section to be repeatedly reproduced through the key input unit 50, the microcomputer 40 stores the disk address corresponding to the start point setting point from the TOC information read from the optical pickup unit 20 in the memory unit. Store at 70.

Subsequently, when the repeat section end point is input from the user again during disc playback, the microcomputer returns the disc address corresponding to the position where the repeat section end point is generated from the TOC information read out from the optical pickup unit 20 and the repeat count for the set section. It receives the input from and stores it in the memory unit 70.

As described above, when the section reproducing signal for reproducing the section set by the user is input through the key input unit 50 while the repetition section setting information input by the user is stored in the memory unit 70, the microcomputer 40 Reads the address of the starting point of the repeating section from the information on the repeating section stored in the memory section 70 to generate a control signal corresponding to the optical pickup section 20.

Accordingly, the optical pickup unit 20 reads and reproduces the disc from the track position of the disc corresponding to the control signal generated from the microcomputer 40. The end point of the repeating section is changed by the user during the playback of the set section as described above. When the interval change key signal is input through the key input unit 50, the microcomputer 40 pauses the playback of the disc.

At this time, when the user performs a rewind (REW) operation or fast forward (FF) operation to input a new end point for the repeating section, the microcomputer 40 updates the end point information for the repeating section stored in the memory unit 70. You will save it again.

Then, the disc is replayed from the starting point of the repeating section, and if the current optical pick-up position provided from the optical pick-up section 20 during the playback for the set section corresponds to the end position of the updated repeating section, the microcomputer starts. 20 detects this and generates a control signal to the optical pickup unit 20 to stop the repetition section reproducing operation.

Then, the microcomputer 40 reads the repetition number from the repetition section setting information stored in the memory unit 70 and performs the replay for the repetition section through the same process as described above by the set repetition number.

2 is a flowchart illustrating a repetitive reproduction process of an optical disc player according to a preferred embodiment of the present invention. Referring to the same figure, the repetitive reproduction process of an optical disc player according to the present invention will be described in detail as follows.

If the repeat section setting key signal is input from the user while the disc mounted on the deck unit 10 is being played (step 101) (step 102), a menu screen output from the OSD unit 100 is displayed on the monitor (not shown). (Step 103).

The user inputs the repeating section setting information including the start point P1 and the end point P2 of the repeating section and the number of repeating playbacks C1 for the set section by referring to the menu screen displayed on the monitor. If the setting information for the repetition period is not input for a predetermined time, for example, 10 seconds (step 105), the control unit of the microcomputer 40 is displayed on the monitor. The menu screen is turned off (step 106) and normal playback of the disc is performed.

On the other hand, when the information on the repetition section is input from the user in step 104 described above, it is stored in the memory unit 70 through the microcomputer 40, the optical pickup unit 20 continues the normal playback of the disc Is performed (step 107).

Meanwhile, the above-described repetition section start point P1 and the repetition section end point P2 are based on the TOC information read out from the optical pickup unit 20 and provided with the position information of the disc track where each section start signal and the end signal are generated. Each track is provided to the microcomputer 40 in the form of an address and then stored in the memory unit 70.

While all the information related to the disc repeat play provided by the user through the above-described step 107 is stored in the memory unit 70, while the normal play of the disc is performed, a key signal for performing the repeat play for the set section is keyed. When input via the input unit 50 (step 108), the microcomputer 40 plays the disc at the start point P1 of the repetition section stored in the memory unit 70, and counts up the number of times of play C2 ( Step 109).

On the other hand, if the section repeat playback cancel signal is input from the user through the key input unit 50 while the disc is being played back through step 109 (step 110), the optical pickup unit 20 controls the microcomputer 40. The repeat play for the section set by the signal is terminated (step 111), and normal play of the disc is performed at the current play position.

On the other hand, if the section repeat play cancel signal is not generated in the above-described step 110 and the normal section repeat play is performed and the play position of the disc reaches the repeat section end point P2 (step 112), the microcomputer 40 The playback of the disc is paused by the control signal (step 113).

At this time, the monitor (not shown) displays an OSD menu screen inquiring whether to change the end point P2 (step 114). If the user inputs the end point P2 for the new repetition section through the key input unit 50, the input is performed. The end point P2 of the set repetition section is updated by storing the positional information on the new end point P2 that has been set in the memory unit 70 (step 115).

After the above-described step (step 115), the microcomputer 40 compares the number of repetitions C1 set in the memory unit 70 with the counted number of playbacks C2 (step 116), and the number of times C1 set by the user is detailed. The operation from step 109 is performed to repeat playback for the set section, and when the number of repeat playbacks set by the user (C1) and the counted repeat counts (C2) coincide with each other, at step 113 Normal playback of the disk is performed from the position of the stopped disk, that is, from the end point P2 of the repeating section (step 117).

The end point change function for the repetition section as described above is particularly useful when the user wants to repeat the learning except for the part he / she is familiar with in the section set during language learning using the language disc. Therefore, it can be useful when you want to continuously change the end point to learn.

As described above, according to the present invention, the user can set the desired section and the desired number of times to automatically repeat the playback while the disk is mounted and played in the optical disk player, and can also modify the end point of the set section during the section repeat playback. There is an effect that can meet the various needs of the user.
