The present invention relates to a recording method of a repeating section for repeating section recording in order to reproduce a section more precisely desired by a user for a repeating section.

Moving Picture Experts Group (MPEG) is a group of video and multimedia experts that have been developed by experts in this field under the auspices of international standards bodies such as the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It provides technical criteria such as compressing a signal, transmitting it, and restoring it again. MP3 stands for MPEG-1 Audio Layer-3, which is one of the audio parts of MPEG technology. By applying MPEG audio compression technology, audio sound information of a CD can be reduced to 1/12.

As such, advances in science and digital audio data processing technology have resulted in portable digital audio players, such as memory means and MP3 players, which enable the accumulation of sound data (ie, audio sound information) in addition to conventional sound storage media such as cassette tapes and the like. Enabled the development of.

MP3 players commonly used in recent years have built-in memory means, so that the desired sound data can be reproduced for a long time without deterioration of sound quality even without inserting a conventional sound storage medium.

1 is a block diagram of a typical portable digital audio player.

Referring to FIG. 1, the MP3 player includes a key input unit 15, a display unit 20, a power supply unit 25, a control unit 30, a decoder 35, a D / A converter 40, and an audio output unit 45. ), The earphone jack 50.

The key input unit 15 may include a play button, a menu button, a pause button, a song selection button for determining whether to play music file data stored in the MP3 storage unit 55, a playback method, a display type on the display unit 20, and the like. Interval repeat recording button. The apparatus may further include a hold switch for preventing the MP3 player from operating even if a user inputs a key.

In addition, the display unit 20 displays the music file recognition information of the MP3 storage unit 35, the music file information being played (for example, the name of the song, the playing time, the sequence number of the corresponding song, etc.), the operation state of the MP3 player, and the like. It is a means to display to. The information displayed through the display unit 20 is determined according to which function the MP3 player includes, and all information that needs to be notified to the user among the function information that can be operated by the MP3 player is displayed on the display unit ( 20).

In addition, the power supply unit 25 is a means for providing power required for performing normal operation. The power supply 25 may be, for example, a portable power supply such as a rechargeable battery, a battery, or an adapter connection for allowing driving power to be applied from an external power source.

In addition, the controller 30 may output the music data stored in the MP3 storage unit 55 through the earphone jack 50 by a user's manipulation through the key input unit 15. The display unit 20, the decoder 35, the MP3 storage unit 55 and the like to control the function.

The decoder 35 reads and decodes the information of the MP3 file stored in the MP3 storage unit 55 under the control of the controller 30 to generate audio digital data.

The D / A converter 40 is a means for converting audio digital data generated by the decoder 35 into an analog signal to generate audio analog data. Depending on the device, a microphone and an A / D conversion unit, which are not shown, may be used to record external voice.

The audio output unit 45 amplifies and waveform-shapes the audio analog data received from the D / A converter 40 and converts the amplified audio analog data into the earphone jack 50 or the speaker ( (Not shown) allows a user to listen to sound data in the best condition.

The portable digital audio player as described above provides a function of repeatedly playing a specific section when playing a file. This repeat playback function will be described with reference to FIG.

Referring to FIG. 2, the MP3 file is played back (S11), and it is checked whether the section repeat recording mode input is input by the user during file playback (S13). As a result of the checking, in the section repeat recording mode, the section repeat start position and end position information selected by the user in the playback file are recorded (S15). Subsequently, it is checked whether the section repeat playback mode is applied (S17), and in the section repeat playback mode, section replay is repeated using section start / end position information (S19).

As described above, only the start position and the end position of a specific section are recorded for the section repeat play, so that a user may not match the start position to be played back with the section repeat play. That is, when the user determines that the start point of a specific section is selected and the user selects the start point, the time point is a delayed time. Accordingly, there is a problem that can not provide the user with the best section repeating position and section start position.

It is an object of the present invention to provide a method for repeating a section of a portable digital audio device capable of compensating for a section repeat playback start position.

A second object of the present invention is to provide a portable digital audio playback apparatus capable of reproducing the stored section repeat files upon copying and storing them in a separate memory using the position and end position information that compensates for the section repeat play start position. The purpose is to provide a method for repeating the interval recording.

A third object of the present invention is to provide a method for repeating a section of a portable digital audio reproducing apparatus capable of storing a section file extension starting with a name of a corresponding file when recording a section file.

Section repeat recording method of the portable audio player according to the present invention for achieving the above object,

In the section repeat recording method in a portable digital audio device,

Playing digital audio data;

Checking whether the reproducing digital audio data is in a specific section repetitive storage mode;

Starting copying of the file from a position where the start point of the corresponding section is compensated when the start point of the section is input in the section repeat storage mode;

And ending the ongoing copying at the end of the section when the section end point is input, and storing the copied file as a section repeating file in a memory.

Preferably, the compensating position at the start point of the section is one syllable or one word or a predetermined time of the corresponding playback file.

Preferably, the section repetition file is characterized in that the name of the file currently in dispute is extended and copied to a new name and stored separately for each section repeating file.

Preferably, the interval repetition recording mode is characterized by copying and storing the interval repetition file of the corresponding section by using the start position and the end position information which compensated the interval recording time point.

Referring to the accompanying drawings, a repeating section recording method of a portable digital audio player according to an embodiment of the present invention configured as described above will be described.

First, as shown in FIG. 3, a memory 120 of a digital audio player (eg, MP3) is allocated an area 120 in which an MP3 file is stored and an area 130 in which an interval repeated playback file is stored.

In such a device, if a section start time and end time are selected for repeated listening to a specific section from the MP3 file currently being played and read from the MP3 storage area 120, the section is copied from the start position to the end position and then copied to the section repeat playback file. Will be saved.

If the section repeat listening mode is performed while playing file 1, the section repeat file in the song is preceded by the name of file 1, and then the section repeat file is expanded with a new name (-A, -B). Copied and saved. For example, the interval repeating file of file 1 is named file 1-A and file 1-B in order to be stored. As another example, the first lyrics at the start of the interval repetition file may be named.

4 is composed of the beginning of the song and the end of the song for one MP3 song in the present invention. When the song starts, it is stored as a section repeating file for repeat listening from section A to section B.                     

In this case, the actual position selected by the user as the start point of the interval repetition is A, and the actual position selected by the end point of the interval repetition is B.

In order to compensate for such a section start position, when the section start point A is selected, a copy is started from the position A 'by compensating for a predetermined time (a position of 3 to 5 seconds before). When the end point of the section is selected, copying (A'-B) is performed up to B.

Here, since the degree of time delay for selecting the start point and the end point of the section varies according to the user, one syllable or a word may be selected as the position before or after the section start and / or end position.

In addition, since the end point of the interval is not substantially different, only the start point of the section can be compensated.

If the user frequently repeats the section, the user may be provided with a setting mode in which the user may select a temporal compensation at the start point of the section repeat or the end point of the section repeat.

FIG. 5 shows that when a section repeat listening section is performed for several sections C, D, and E in one song, the T1 of a temporal starting position for each section is performed, and the compensated starting position of each section is shown. Copies from (C ', D', E ') to the end position and stores them in separate memory areas. Here, T1 in each section may be different or the same.

A preferred embodiment of the present invention will be described with reference to FIGS. 6 to 8.

6 is a flowchart of the interval repeating recording method of the present invention.                     

First, when the MP3 file is played back (S101), the user checks whether the file being reproduced is in the section repeat recording mode (S103). At this time, if a start point of a specific section is selected in the section repeat recording mode (S105), the previous position is determined as a start position at the start point of the section selected by the user to start copying the section repeat file (S107).

Here, the section start position determines the section corresponding to the position of -3 to -5 seconds before the section starting point as the start position. In this case, the compensation position at the start of the section may be selected from a predetermined time or one syllable or one word.

Thereafter, when the user selects the end point of the section (S109), the file copying ends up to the section end position at this time, and the copied section repeating file is stored in the memory (S111).

In this case, when the end point of the section is selected, the compensation of the end point of the section may be selected as one of a predetermined time, a syllable, or a word as a position before the end of the section.

As described above, when the section time point in the section repeat storage mode is selected, the file copying starts from the section start position at the same time as the playback of the current file. When the section end position point is selected, the file copying ends at the section end position. At this time, the copied section repeating file is stored in a separate memory, and when a name is named, it is extended to the file name currently being played.

Accordingly, when a section repeat file is to be played, a desired section repeat is played by selecting and playing the section repeat file.                     

7 is another example of the interval repeating recording method of the present invention.

Referring to FIG. 7, when an MP3 is played and a user selects a section start point in the section repeat recording mode (S123 and S125), the start position information is stored by compensating the position of the section start point (S127) and the section ends. If a viewpoint is selected, location information on the end point of the section is stored (S129 and S131).

Then, the file corresponding to the section start position information and the section end position information is copied and stored in the section repeating region as a section repeating file, and the name of the reproduced file and the name of the section repeating are named after storing. It is stored in a separate memory (S133).

8 is a diagram illustrating reproduction of a section repeating file according to the present invention.

Referring to FIG. 8, when the section repeat play is started (S141), in the full listening mode, the section repeats the repeated files stored in a separate section repeat file area in sequence (S143, S145). The particular section file stored in the repeating file area is repeatedly played (S144, S146).

As described above, the present invention can compensate for the section start position and the section end position in the playback file of the portable digital audio device by compensating for the section start position and the section end position, and store the copied section in a separate memory and reproduce the same during playback.

So far, the present invention has been described with reference to the preferred embodiments, and those skilled in the art to which the present invention pertains to the detailed description of the present invention and other forms of embodiments within the essential technical scope of the present invention. It can be implemented. Here, the essential technical scope of the present invention is shown in the claims, and all differences within the equivalent range will be construed as being included in the present invention.

As described above, according to the section repeated recording method of the portable digital audio device according to the present invention, after compensating the start position for a specific section of the playback file, copying from the position to the end position and storing or recording the data in a separate memory, By reproducing, there is an effect that the section can be repeatedly played for the desired section.
