And setting a corresponding mapping region of the section information unit as a section for repeat play and repeating the play of the mapping section.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 shows a schematic circuit block configuration of a general digital audio player.

As referred to herein, the CPU 10 is connected to the communication interface device 12 so that the digital audio data is connected to the PC 13 or other data server side through the communication interface device 12. The digital audio data connected to and input to the CPU 10 is configured to be stored in the (nonvolatile) data memory 15.

The CPU 10 includes various function selection buttons (PLAY, REW, FF, STOP, etc.) of the digital audio player, a start point setting key 14-1, an end point setting, and an execution key 14-2 for setting a repeat play section. It is configured to apply various key input information of the key input unit 14, including (), and to input digital audio data contained in the expansion memory card 11 through the slot. CD, MD, HDD through the slot Digital audio data contained in the portable data storage medium 21, such as FLOPPY DISKETTE, is input.

Audio data among the digital signals processed by the CPU 10 is configured to be output to the speaker 20 which is a voice output device through the decoder 18 and the DAC 19. In addition, when caption data is mapped to the digital audio data, the digital caption audio data may be processed by the CPU 10 and then output to the screen display device 17 through the screen display control and the character generator 16. An additional configuration may be further included. The audio reproduction output process of the digital audio player configured as described above is as follows.

When downloading digital data such as language learning or singing practice from the outside, if the data source is stored in the PC 13, it is connected through a wired / wireless communication interface device 12 such as RS232C, parallel port, USB, IrD, BLUETOOTH, etc. If the data source is data existing in the database server of the wired switching center, the CPU 10 connects to the wired switching center server through a communication modem (not shown).

The digital audio data downloaded from the outside by the CPU 10 through the communication interface device 12 or the communication modem is stored in the data memory 15, and the stored data is stored in the function execution program selected by the key input unit 14. Will be processed accordingly. That is, the digital audio data is processed by the decoder 18 and the DAC 19 to be output as a voice signal through the speaker 20. If the digital caption is synchronized with the digital audio, the caption data is displayed on the screen. And it is processed by the character generator 16 is to be output through the screen display device (17).

In addition, the digital audio data of the (non-volatile) expansion memory card 11 input through the slot is also processed in the same manner as described above and outputted as voice and subtitle information to the speaker and the display device, respectively.

To repeat playback of a specific section using a digital audio player, first select the repeat playback section setting mode using the function selection key provided on the key input unit 14, and then set the start point setting key 14-1 and the end point. An arbitrary section should be selected and registered with the execution key 14-2. Here, the mapping method of the digital audio in the present invention will be described first. [0047] Data composed of the digital audio data format is an audio access unit (audio access unit). unit: AAU). AAU is a frame of the minimum unit constituting music / voice of MP3 data. In addition to the MP3 data format, the digital audio organized in a frame unit includes audio portions of all the digital video disk (DVD) standards and the moving picture coding experts group (MPEG) standards. The interval information unit for dividing the digital audio file is a word unit. It may be a unit of measure, sentence, and caption display. The mapping step refers to a step of dividing the digital audio file by the interval information unit and associating the audio with the corresponding interval unit. If there is a digital audio file for a horse, it consists of a number of AAUs, and the interval information unit is "Good Morning", where the location of the AAU corresponding to the beginning and end of the "Good Morning" is indicated by time, time, and mark. The mapping step is to store the number, AAU number, etc., and read this information when playing on a digital audio player to respond to "Good Morning." It is used to represent the "Good Morning" at the time the audio is being played.

The section for repeat playback and the playback execution process are as follows.

First, when digitalizing audio or learning content, the digital audio data file is divided and mapped into interval information units. Here, the section information unit constituting the digital audio file may be one of word units, word units, sentence units, or the minimum unit displayed on the screen to determine a section to be repeatedly played back by a provider providing repeat section information.

Therefore, a specific section of the digital audio file to be repeatedly reproduced is set based on the section repeating unit information determined as described above, wherein the section start and end time points are determined by the mapping unit of the digital audio data.

For example, if a user wants to set a specific section to be repeatedly played in digital audio, first, when the user presses the start point setting key 14-1 provided in the key input unit at an arbitrary point (time) while the digital audio is playing, the system The control CPU 10 detects this and sets the start point of the mapping section of the word unit, the measure unit, or the sentence unit at the presently reproduced time point as the start point of the repeat playback. The start point information of such repeated playback is stored in the memory via the CPU as an AAU value.

Subsequently, when the end point setting and execution key 14-2 are pressed to determine the end point of the repeat playback section of the digital audio, the end point of the word section, the word unit or the word unit or sentence unit mapping section at the point (start point) is repeated. Set as or the end point immediately before the start point of the next mapping section. Here again, the end point information of the repeat playback is stored in the memory via the CPU as another AAU value. Examples of the start point and end point information of the repeat playback are time, time, mark number, AAU position value, data position value, and the like. Can be mentioned.

In particular, when the end point setting and the execution key 14-2 are input for setting the repeat play section by the user, the end point of the mapping section of the word unit, the measure unit, or the sentence unit at the point (point) is repeated. The replay playback execution mode automatically occurs at the same time as the end point of, or the position immediately before the start point of the next mapping section is set as the end point. In particular, when setting just before the start point of the mapping section as the end point, it is possible to operate by setting only the start point of the section in the mapping process.

On the other hand, unlike the specific section setting execution control method of setting an arbitrary section for repeat playback through the two key operation as described above, and repeatedly playing the set section, one key operation (one touch) It is also possible to selectively repeat playback by measure unit, word unit, sentence unit, and the like.

In this case, when the end point setting and execution key 14-2 are inputted at the time of arbitrary digital audio playback, the mapping unit section information (measures, words, sentences, captions) hanging on the key input point is displayed on the screen. Caption) is selected and the section information of the selected mapping unit is automatically played repeatedly. That is, it is possible to designate a specific section for each mapping section information unit and to execute repetitive playback in a single operation.

2 is a flowchart illustrating a process of setting an arbitrary repeat play section and executing a repeat play according to the present invention.

As referred to herein, if the start point of a repeat section start key for repeat playback of a specific section during digital audio playback according to the selection of the digital audio playback mode is selected, the start point of the mapping unit section information of the current audio data at the corresponding point in time. Set as the starting point of the interval repeat.

Next, it is determined whether to set the end point of the repeat play section and input the execution key. In this case, when the end point is set and the execution key is input, the end point of the section information of the currently played section is set as the end point of the section repeat, and the repeated section is automatically repeatedly played.

3 is another embodiment of the present invention, in which a simple measure unit, a word unit, a sentence unit, and a caption unit displayed on the screen may be selectively executed by a single key operation. It may be.

Here, the measure unit, word unit, and sentence unit refer to one digital audio mapping unit, and when the end point setting and execution key are input during digital audio playback, the mapping unit section information (measure, word, sentence) hanging at the key input point is input. Is selected and the section information of the selected mapping unit is automatically and repeatedly played. However, the one-touch repeat playback process performed by the single key operation is one set by the end point setting and the execution key input. Since only the mapping unit interval of is selected and replayed, there is a possibility that the mapped unit interval is short in the case of language learning, which may cause a problem that the conversation is interrupted. If you do not print the conversation of only one speaker and do not output the conversation of the other party, the conversation is blocked in the middle. Therefore, in the present invention, the end point setting and the execution key and an additional function button are added, and the end point setting and the execution key and the additional function button are pressed simultaneously, or the preceding section or the trailing section of the selected mapping section. It is possible to set to repeat playback of at least two or more consecutive mapping sections. By setting two or more mapping sections, it is possible to output data (language conversation or song lyrics) sufficiently without interruption of long conversations, so that learning can be performed more efficiently. The function button can be easily installed in the key input unit. Basically, the trailing section of the selected repeat play section is automatically added to allow the play to be repeated. By adding the selection function of the preceding section or the following section, it is possible to set the confirmation section of the repeat playback section, or it is possible to extend two or more extension sections to n sections. In other words, when the user selects the n extended section, the n section is automatically played repeatedly including the selected repeating section when the end point setting and the execution key are pressed. This function is useful when the repeat play section is set by pressing the repeat play command, i.e., setting the end point and pressing the execution key, and the dialogue is cut off in the middle. It is possible to achieve this by pressing the start point setting key 14-1, the end point setting and the execution key 14-2, which have been previously installed. Alternatively, the end point setting and execution key 14-2 may be configured to activate the section extension function by double-clicking for a predetermined time of 1 second or less. Such a function can be easily implemented by modifying the control program of the digital audio player.

In the present invention as described above, the start point and the end point of the repeat play section are set by breaking the syllable unit of the speech syllable or the song lyrics during repeat play learning such as language or song lyrics using a digital audio player. It is possible to prevent the occurrence of voice noise in the portion.

In particular, the present invention can obtain a smooth switch operation of the audio output at the start point and the end point during repeat execution in the repeat playback section, thereby improving the performance of the digital player.

In addition, the present invention can set and execute an arbitrary section for repeat playback by only one key operation or two key operations, thereby obtaining a unique effect of facilitating the operation of a digital audio player.
