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 improved DVD system according to a preferred embodiment of the present invention, the deck unit 10, the signal processing unit 20, the image decoder 30, the character decoder 40, the audio decoder 50 , A keypad 60, a controller 70, an A / D converter 80, a memory 90, and a D / A converter 100.

In the DVD system configured as described above, when the language disc is inserted into the deck unit 10 and played, the signal processing unit 20 receives the signal of the reproduced disc and provides the image signal to the image decoder 30. The text signal corresponding to the caption is separately provided to the text decoder 40 and the audio signal to the audio decoder 50, respectively.

The video decoder 30 decodes the video signal, and the text decoder 40 decodes the text signal and provides the video signal to the monitor, so that the video and subtitles are displayed on the screen, and the audio decoder 50 decodes the audio signal. To output sound through the speaker.

At this time, when the user presses the recording button provided on the keypad 60 to record his voice (pronounced) and compare it with the original sound recorded on the disk, the control unit 70 responds to the recording key signal generated from the keypad 60. By generating a control signal to the character decoder 40, the subtitle output is interrupted and the position information of the disc on which the subtitle of the screen displayed on the current screen is recorded is provided from the signal processing unit 20. And the position where the image data is recorded with reference to FIG.

The subtitle corresponding to the video data V is recorded at the previous position P1 where the video data is recorded, so that the subtitle data P1 is displayed on the screen while the subtitle data P1 is read first and then the video data V1 is played back, and the next video data V2 The caption data for is stored in P2.

Therefore, the control unit 70 receives the position P1 of the caption data for the video data currently being reproduced when the recording key signal is generated from the signal processing unit 20 and stores it in the memory unit 90, and again during the disc playback, the signal processing unit ( 20, when the position P2 of the next subtitle is detected, the detected position P2 is also stored in the memory unit 90, and then a control signal is generated in the deck unit 10 to move the read position of the disc to P1. Next, the operation of the deck unit 10 is paused.

When the user inputs his or her own voice (not shown), the A / D converter 80 receives the voice signal, converts it into digital data, and stores the converted digital data in the memory unit 90. When the key operation signal for learning is input, the control unit 70 generates an output control signal to the memory unit 90 so that the voice data stored in the memory unit 90 is output to the D / A converter 100. .

When the output of the above-mentioned voice data is finished, the control unit 70 generates a control signal to the deck unit 10 to release the pause, and turns on the caption output so as to perform normal playback of the disc again at the position of P1. .

When the next subtitle P2 is detected from the signal processing unit 20 during the normal playback, the control unit 70 pauses the operation of the deck unit 10 again, and then the user described through the OSD unit not shown. You will be asked whether you want to continue recording.

At this time, if the user generates a key operation signal to perform the above-described recording operation again, the DVD system repeats the voice input process of the user described above, and if the user wants to terminate the recording operation, the DVD unit pauses the deck unit 10. Generate a release signal to allow the disc to play normally.

A process of performing language learning according to the present invention using the DVD system having the above configuration will be described in detail with reference to FIG. 3.

When the language disc is inserted and played in the deck unit 10 of the DVD system (step 201), when the user presses the record button provided on the keypad 60 to record his voice and compare it with the original sound recorded on the disc ( In step 202, the control unit 70 turns off the caption output of the character decoder 40 (step 203).

Then, the position information P1 of the disk on which the caption of the screen displayed on the current screen is recorded is received from the signal processing unit 20 and stored in the memory unit 90 (step 204), and the position P2 of the next caption is stored. If detected, the detected position P2 is also stored in the memory unit 90 (step 205). The control unit 70 generates a control signal to the deck unit 10 to move the read position of the disc to P1, and then the deck unit The operation of 10 is paused (step 206).

In the pause mode as described above, the controller 70 checks whether or not the user's voice is input. If the user's voice is input from the microphone (not shown) (step 207), the input user's voice is an A / D converter ( 80 is converted into digital data and then stored in a predetermined space of the memory unit 90 under the control of the control unit 70 (step 208). It continues until it is finished (step 209).

Next, when a key operation signal for comparison learning is input from the keypad 60, the control unit 70 switches the current pause mode to the reproduction mode, wherein the image data to be reproduced is, for example, V1 of FIG. Image data of the section (the image section corresponding to the user's voice stored for language learning), and the user's voice corresponding to the image of the section V1 is read from the memory unit 90 and output to the speaker (not shown) (step) 210).

That is, under the control of the control unit 70, the user's voice corresponding to the video of the V1 section is simultaneously output.

Accordingly, the user may realize effective language learning through comparative analysis of the voice pronounced by him and the original voice previously heard without a corresponding subtitle.

On the other hand, if it is checked whether the user's voice output is terminated after the step 210 (step 211), the controller 70 searches for the P1 position to perform a normal playback operation and simultaneously outputs the subtitles of the audio decoder 50. Is turned on (step 212). Therefore, on the monitor, the image of the section V1 and the image of the section V1 in which the caption information is composed in the OSD form is displayed on the monitor, so that the user can obtain his or her own evaluation of the voice previously pronounced. Could be.

Then, if it is determined in step 213 that the playback position reaches the P2 point, that is, the video playback of the V1 section is completed, the current playback mode is switched to the pause mode under the control of the control unit 70. (Step 214).

At this time, on the monitor, do you want to pause the deck 10 and at the same time repeat the OSD text that asks you to repeat the user's voice recording, for example, user voice recording? OSD characters such as As such, the text of the repetition statement displayed on the monitor may be displayed through part or all of the screen.

Therefore, when the repeated query character is displayed on the monitor as described above, the controller 70 checks whether or not a key operation signal for the user voice listening repetition learning is input for a predetermined time period, for example, 10 seconds ( Step 215), if there is no input of a key operation signal for repeating the user voice recording for a predetermined time as a result of the check, the DVD system performs a normal playback operation under the control of the control unit 70, that is, P2 shown in FIG. The playback operation from the position is performed (step 216).

On the other hand, if a key operation signal for repetitive learning is input for a predetermined time as a result of the check in step 215, the subsequent steps are repeated from the above step 203, that is, the user voice is stored thereafter. The language learning process by the user's voice recording according to the present invention will be repeated by removing the caption output and displaying the image corresponding to the output of the stored user's voice.

As described above, according to the present invention, a section for user voice listening learning is set during language learning using a DVD system, a user voice for the section is stored, and the user voice is stored without corresponding subtitle data. By outputting the image to the speaker and the monitor, it is possible to realize the language learning through the comparative analysis of the original sound and the voice pronounced by his own to improve the learning efficiency.
