Referring to the flowchart of the learning method of the present invention shown in Figure 2 the operation of the learning apparatus according to the embodiment configured as described above is as follows.

First, the disc 100 records language audio data (for example, audio data corresponding to English conversation) and language video data (for example, sentence subtitles corresponding to English conversation or a person speaking English). The entry data is recorded at a certain section of language audio data, for example, at the beginning of each sentence of the English conversation.

Therefore, when the learner provides the key signal corresponding to the learning mode to the controller 270 through the key input unit 280 (S1), the controller 270 controls the switching unit 500 to control the audio signal processor 250 and the speaker ( After the 600 is connected (S2), the CD deck unit 210 is controlled to read / play the disc 100 (S3).

The CD deck unit 210 is a control device for reading / reproducing language video data and audio data recorded on the disk 100. As shown in FIG. 1, the optical deck apparatus 10 and the RF ( Radio Frequency) An amplifier / servo signal processing unit 20, an actuator / motor driving unit 30, a disc motor 40, and the like are provided. The language video and audio data read / reproduced by the CD deck unit 210 is provided to the digital signal processor 220. The digital signal processor 220 demodulates the read / reproduced language video and audio data to detect the frame sync signal, detect the error, and correct the error. Then, the table of contents (TOC) information and the sub data of the disc are stored. And the video and audio data are provided to the MPEG decoder 230, respectively.

The MPEG decoder 230 expands the error-corrected video data and the audio data, and then converts the video data into an analog RGB signal, converts the video data into a composite video signal, and provides the converted video signal to the video signal processor 240. Is converted into an analog audio signal and provided to the audio signal processor 250.

In addition, the MPEG decoder 230 detects the entry data inserted in a predetermined section unit of the audio data string and provides the same to the controller 270.

The video signal processor 240 processes the video signal provided from the MPEG decoder 230 to the monitor 260 by processing a video signal, and the audio signal processor 250 processes the audio signal to switch the signal 500. To provide. At this time, since the switching unit 500 is connected to the audio signal processing unit 250 and the speaker 600 under the control of the control unit 270, the audio signal of the audio signal processing unit 250 passes through the switching unit 500. Provided to the speaker 600.

On the other hand, if entry data is detected from the MPEG decoder 230 (S4), the controller 270 stores the detected entry data in the internal memory (S5). Then, the controller 270 controls the CD deck unit 210 to stop the CD deck unit 210 from reading / playing and switch to the pause mode (S6) and then controls the switching unit 500 to control the audio signal. The processor 540 and the speaker 600 are connected (S7). The controller 270 provides a reference clock for A / D conversion to the A / D converter 510 and provides a control clock for data writing to the salt memory 520. Accordingly, the data provided through the A / D converter 510 is written to the memory 520 (S8), and the controller 270 drives an internal counter (not shown) to start counting ( S9).

The learner listens to the learning sentence read / played from the disc 100 through the speaker 600, and then, while the video CD 200 is switched to the pause mode, the learner reads and reproduces the learning sentence read / played through the microphone 300. The pronunciation is thus pronounced by the learner. The audio signal of the microphone 300 is provided to the amplification and compensator 400 to remove the amplification and noise, and is then provided to the A / D converter 510 to be digitally converted and stored in the memory 520.

When the learner provides the learner voice listening key for listening to the learner's voice through the key input unit 280 (S10), the control unit 270 provides a read clock to the memory 520 and converts the D / A. A reference clock for D / A conversion is provided to the unit 530 to read data stored in the memory 520.

The learner's audio data read from the memory 520 is provided to the D / A converter 530, converted into analog, and then processed by the audio signal processor 540 to process the audio signal, and the speaker is passed through the switching unit 600. It is provided at 700 (S11).

The learner will be able to correct their pronunciation by comparing their pronunciation heard from the speaker 600 with the pronunciation read / reproduced in the disc.

The controller 270 continuously searches whether a repetition key signal or a learning mode release key is provided from the key input unit 280 during the execution of the processes S10 and S11 (S12 and S15). When the learner provides the control section 270 with a predetermined section repetition key using the key input unit 280 (S12), the control unit 270 plays the entry data stored in the step S5, that is, the immediately preceding playback section of the language video and audio data. After detecting the entry data referred to for (S13), the optical pickup device 10 of the CD deck unit 210 is moved to a position where the entry data detected in step S13 is recorded on the optical disc 100. (S14). Then, the process of S2 and below is performed again.

Meanwhile, as shown in FIG. 2, in step S15, the controller 270 searches for a key signal corresponding to the release of the learning mode from the key input unit 280 while continuously increasing the count value (S15). If the key signal corresponding to the learning mode release is provided before the count value reaches the preset value, the control unit 270 causes the learning mode to be released (S16) and then switches the video CD to the normal playback mode (S17). In this case, the key signal corresponding to the learning mode release may be provided with a learning mode release key separately from the key input unit 280, and the first learning mode key signal may be provided using only the learning mode key provided in the key input unit 280. If provided, the controller 270 may recognize the learning mode, and if the second learning mode key signal is provided, the controller 270 may be programmed to recognize the learning mode release.

When the video CD is switched to the normal play mode by the step S10, the CD deck unit 210 does not read / play the disc on an entry basis, but performs normal play.

Meanwhile, in step S17, if the key signal corresponding to the learning mode release is not provided until the count value reaches the preset value (S18), the controller 270 controls the CD deck unit 210 to detect the next entry data. The read / reproduce of the disc 100 is performed until it is performed (S2).

In this case, after converting the count value of the control unit 270 to time data, the time data is displayed on the monitor 260 (OSD) to inform the learner of the timing of providing the learning mode key or the learning mode release key to the learner. It would be desirable to provide a convenient function.

As described above, according to an exemplary embodiment of the present invention, the present invention is configured to automatically read language learning data in a predetermined section unit, thereby eliminating the trouble of a learner arbitrarily setting a reading / reproducing section, and repeating the language learning data in a certain section. By reproducing, the learning efficiency is improved, and the pronunciation of the audio audio data recorded on the disk and the pronunciation of the actual learner can be compared and corrected.
