And a second memory 211 for storing external data.

The operation of the apparatus for reproducing digital media contents according to the present invention configured as described above will be described with reference to FIGS. 2 to 6.

Sentence information is edited in the personal PC with the sentence information input according to the user's request (S10).

In operation S20, it is determined whether the edited sentence is selected for short-term transmission.

Subsequently, if the terminal transmission is selected, the determination result (S20), the edited sentence is transmitted to the terminal (S30).

Then, the transmitted sentence is stored and reproduced as desired through storing, reproducing / repeating sentence and pattern drill (S40).

In this case, the process of editing the sentence will be described with reference to FIG. 3. First, when a wave file is to be changed into a content file, the wave file is compressed into a digital media file (S101).

The sentence information is extracted by restoring the compressed file (S102).

The sentence is reconstructed after setting options as desired by the user with reference to the extracted sentence information (S103).

Subtitle information is added to the reconstructed sentence (S104).

Then, a sentence is constructed according to the sentence and the caption information (S105).

Unlike the above, if the user wants to store the sentence information while receiving the content that is not edited by using the editing software and playing the content on the digital media terminal 200 in the personal PC, referring to FIG. Start (S201).

Subsequently, the sentence of the reproduced content is reproduced (S202).

The reproduced content is decoded to detect a section in which a silent section exists and store sentence section information in a second controller (S204 to S205).

At this time, the detection of the silent section is to detect from the beginning of the silence to the end of the silence using the algorithm in the decoded content or to detect the silence information obtained by using the analog final output.

When the reproduction after the storing is completed, the sentence section information stored in the second controller is stored in the second memory to enable functions such as sentence repetition, drill, and pattern drill (S206 to S207).

The operation in the case where the stored sentence is to be reproduced or repeated as described above will be described with reference to FIG. 5. First, content reproduction is started, sentence reproduction is performed, and content is decoded (S301 to S303).

Then, it is determined whether the sentence repeat mode is set (S304).

Subsequently, if the sentence repetition mode is not set, the determination result (S304) determines whether the sentence section information is present (S305).

As a result of the determination (S305), if the sentence section information exists, the sentence information is stored in the second memory (S306).

On the other hand, if the determination result (S304), the sentence repeat mode is set, it is determined whether the sentence section information is present (S307).

As a result of the determination (S307), if the sentence section information is present, the sentence is repeated (S308).

When the playback ends, the repeated sentence information is stored in the second memory (S309 to S310).

In addition, when the user selects the pattern drill mode, referring to FIG. 6, sentence information is first analyzed (S401).

Then, the analyzed sentence information is reproduced, and the user's voice is recorded according to the reproduced sentence information (S402 to S403).

Subsequently, the reproduced sentence information is reproduced again, and the recorded voice is reproduced (S404 to S405).

In addition, it is determined whether n + 1 sentences or n-1 sentences are selected in the pattern drill mode, that is, in the next section of the sentence, through the sentence forwarding +/- button in the next section of the currently reproduced and recorded sentence (S406).

Subsequently, when the sentence turning mode is selected, the determination result (S406) is moved to the next sentence, and the process returns to the step (S402) to perform a pattern drill (S407).

On the other hand, if the sentence turn mode is not selected (S406), it is determined whether the pattern drill mode is finished (S408).

As a result of the determination (S408), if the pattern drill mode is not terminated, the current sentence is repeatedly moved to the current sentence in order to pattern drill repeatedly, and the process returns to the step S402 to perform the pattern drill.

Subsequently, when the determination result (S408), the pattern drill mode is finished, the pattern drill is released (S409).

As described above, the sentence editing process in the method for reproducing digital media contents according to the present invention will be described with reference to FIGS. 7A to 7F.

First, as shown in FIG. 7A, since the content of the digitized analog audio (for example, * .wav file) cannot be used as it is because the memory file capacity is very large, about 1 by performing digital compression (for example, * .mp3 of mpeg). You can get a compressed file as small as / 10 to 1/40.

For example, sample.wav is changed to sample.mp3. At this time, mp3 uses digital compression. In order to use less memory, it can be compressed to a size of 1/40 with a sampling frequency of 16 kHz and a playback bit rate of 32 Kbps.

Since the compressed file is difficult to obtain the sentence information of the content, it is restored again as shown in FIG. 7B to obtain a wave file having a small file size. In this case, the size information of the content is analyzed and stored as data.

If the search is performed after the silent section is set in the stored file as shown in FIG. 7C, the sentence information is extracted and displayed as shown in FIG. 7D.

At this time, the reference for setting the silent section is set to the threshold value, that is, the size of the sentence and the interval in time units.

In order to allow the client to use the caption information in the extracted sentence information, caption characters are added to each sentence as displayed in FIGS. 7E and 7F.

In addition, as shown in FIG. 7G, caption / test information may be added to desired sentence information by using a caption / test file generation menu in sentence information to which caption letters are added.

Accordingly, the client may store the edited sentence information as described above and store the file if the user wants to download the stored sentence information.

If the sentence repeat mode is set, it is determined whether the current playback position is a sentence division section, and if it is a sentence division section, it is determined that one sentence has been played. Repeat until you enter.

In addition, if the pattern drill mode is set, the sentence play and voice play are repeated repeatedly, and the pattern drill is sequentially executed from the beginning of the content by replaying the sentence, recording the voice, replaying the played sentence, and replaying the recorded voice. You can proceed.

As described above, the apparatus and method for reproducing digital media contents according to the present invention has the following effects.

First, it is possible to play sentence-by-sentence and drill recording using sentence information, so that sentence-by-sent learning can be made efficiently, and by repeatedly playing sentences indefinitely, the effect of listening ability related to language can be enhanced.

Second, the ability to play a sentence and to record the pronunciation of yourself pronounced by the same sentence contents for a predetermined time can increase the reading ability.

Third, the sentences are pre-listened to play the sentences for a few seconds quickly to know what sentences are in one content file, so that convenient movements can be made in units of sentences, thereby realizing convenient functions not present in existing digital contents.

Fourth, it is possible to effectively use the language content by making the sentence information directly available in the playback device without using a PC editor.
