The present invention relates to an automatic section repeat playback apparatus for data and a method of playing the same, and more particularly, to an automatic section repeat playback apparatus and a playback method for data for easily and repeatedly playing a desired section automatically.

In general, while playing data formed of audio or video using a cassette, a CD player, an MP3 player, a DVD, a video, or the like, a user may repeatedly play a specific section. In particular, in the case of language learning, a user frequently plays a particular section repeatedly.

To this end, various repetitive playback methods have been proposed. In general, in the case of a cassette, a repeat playback key is formed. When the repeat play key is selected during tape playback, the play retreats by retreating from the moment when the repeat play key is selected for a predetermined time, for example, about 4 to 8 seconds. That is, if the repeat play key is selected, rewinding is performed for 4 to 8 seconds, and then the play is performed again. In this case, the repeat play count may be set in advance or may be set according to a user's selection.

However, in the conventional repeat playback method, since the repeat playback time is set in advance, there is no guarantee that only a section desired by the user is repeatedly played when the repeat playback key is selected and repeated playback. That is, in the repeated playback, the playback is repeatedly played from the point earlier than the start point of the section desired by the user, and is reproduced up to the portion not desired by the user, or is repeatedly played from the later point, so that the section desired by the user cannot be completely played. Therefore, there is a problem in that the user cannot repeatedly play only a desired section.

In order to solve this problem, a method for allowing a user to directly set the repetition period is proposed. In this method, a setting button is provided, and when the user selects the setting button from the start point and the end point of the section to be repeatedly played, the section between the start point and the end point is repeatedly played. In this case, the repeat play count may be set according to a user's selection.

By the way, the problem of the repeated playback method, there is an advantage that the user can repeatedly play the desired section, but there is a problem that occurs because the user must set the section directly. That is, in order to set the section, the user has to play once and then the user needs to find the starting point and the ending point by manually rewinding to set the starting point and the ending point of the desired section.

On the other hand, in recent years, language learning is often conducted using a storage medium such as a DVD or a CD storing digital audio data and video data using a playback device such as a DVD player or a CD-ROM of a PC. When data is played back using a playback device such as a DVD player or a CD-ROM of a PC, a playback screen 70 as shown in FIG. 4 is displayed on the monitor. On one side of the playback screen 70, a selection window 73 is provided with a plurality of selection buttons for designating a mode, and on the other side, a text window 71 for displaying the sentences being played is formed.

A plurality of sentences are displayed sequentially in the text window 71, and a selection icon for selecting a sentence is formed in the player of the sentence. The selection window 73 includes a page repeat button 75 for recognizing a plurality of sentences displayed on the text window 71 as one page so as to repeatedly reproduce the sentences on a page basis, and a sentence for each sentence included in the page. Each sentence repeat button 77 is selected so as to be repeatedly played back a plurality of times, and a plurality of selection buttons are formed.                         

In the case of using such a reproducing apparatus, the repetitive reproduction of a sentence or a page can be performed. However, when a repetitive reproduction of a sentence or a page is required, the repetition frequency must be set directly. In addition, when the page is repeatedly played, each sentence is repeatedly played the same number of times. In general, if you listen to several sentences on a page, there is a sentence that can be understood only once. There will be a sentence. In such a case, if each sentence is repeated and reproduced by the same number of times, the sentence to be understood is listened to several times, and the efficiency is significantly reduced in terms of time and concentration. To this end, although the selected sentence can be set to be repeatedly played during the repetition of the page, it is not only cumbersome because the user needs to set the repetition frequency directly, but also has to adjust the repetition frequency of the sentence according to the user's understanding. It is. In addition, since a plurality of buttons are required for repeat play selection, there is a problem that it is difficult to apply to a cassette or a CD player which is a conventional general playback device.

Accordingly, it is an object of the present invention to provide an automatic section repeat playback apparatus and a method for playing back data that not only can repeatedly playback a section desired by a user as many times as desired, but also can easily perform a repeat playback operation.

According to the present invention, there is provided an automatic section repeat playback apparatus for data, comprising: a data storage unit for dividing and storing data into a plurality of data sections; A user interface having a plurality of selections for allowing a user to select reproduction of the data; If the repeat play is selected within the preset repeat play selection time during the data play, the repeat play data section immediately before the play data play section is selected, and if the repeat play is selected after the repeat play select time, the currently play data section is selected. It is achieved by an automatic repeat playback device comprising a control section for repeating playback.
Here, the repetitive playback selection time may be set based on a preset previous repeat selection area and a current repeat selection area among the data areas, and may be determined by the playback time of the previous repeat selection area and the playback time of the current repeat selection area. Can be.

The data may include audio data having a data section divided by time unit and image data having a data section divided by the same time unit as the data section of the audio data.

If the controller selects an arbitrary selection unit of the user interface during the repeated playback of the audio file, it is preferable to cancel the repeated playback of the audio file.

The data storage unit preferably stores information on at least one of a start point and an end point of each section of the data.

Meanwhile, according to another aspect of the present invention, there is provided a method for automatically repeating reproduction of data, the method comprising: dividing the data into a plurality of data sections; Selecting repeat play while playing the data; If repeat play is selected within a preset repeat play selection time, the data play section that is played immediately before the playing data section is repeated, and if repeat play is selected after the repeat play selection time, the currently playing data section is repeatedly played. It can also be achieved by the automatic interval repeat playback method characterized in that it comprises a step.

The repetitive playback selection time may be set based on a preset previous repetition selection area and a current repetition selection area among the data areas, and may be determined by a reproduction time of the previous repetition selection area and a reproduction time of the current repetition selection area. .
Wherein the data comprises an audio file and an image file; The dividing of the data may include dividing the audio file into sentence units and dividing the video file into the same time units as the audio file.

The dividing the data into a plurality of data sections may include storing information about at least one of a start point and an end point of each section of the data.

If an arbitrary selection unit of the user interface is selected during the repeated playback of the audio file, the method may further include canceling the repeated playback of the audio file.

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

This playback device allows you to repeatedly play a section you want to play repeatedly during data playback. It applies to any device that can play data such as a cassette, CD player, MP3 player, DVD player, video, PC, etc. can do.

As shown in FIG. 1, the present playback apparatus includes a data storage unit 5 for dividing and storing data into a plurality of data sections that can be repeatedly reproduced, and a plurality of selection buttons so that a user can select playback of data. A user interface 1, a synchronization program 7 for synchronizing various types of data with each other, a memory 3 in which the setting contents of the repetitive playback section according to the reproduction time of the data are stored, and the user repeatedly playing the data The control unit 10 selects and repeats one of the data section being reproduced and the data section reproduced immediately before the data section being reproduced.

The data storage unit 5 may be used as various storage media in which data is stored, and cassette tapes, CDs, DVDs, general memories, and the like may be used depending on the playback apparatus. The data storage unit 5 may store audio data such as music or voice, and image data including a video such as an image, a graphic, or a text.

Recently, a digital audio file or a video file of digitally formed audio data or video data is widely used. When a digital audio data file and a video data file are simultaneously played, the digital audio file and the video file are synchronized. There is a need for a synchronization program 7 to reproduce. Accordingly, the playback apparatus is provided with a synchronization program 7 so as to synchronize and output the digital audio file and the video file. The synchronization program 7 may use standardized multimedia programming languages that are widely used, such as Synchronized Multimedia Integrator Language (SMIL).

Here, the data storage unit 5 stores a timing tag file, which is timing information indicating the start point and the end point of each section of the data of the digital audio file. The section of the digital audio file is divided into different criteria according to the type of audio data. For example, if the digital audio file is music, each song may be divided into one section, or the prelude, one section, two sections, and two sections of the song may be divided into one section. In addition, when the digital audio file is composed of a plurality of sentences such as a speech, lecture, or song, each sentence may be set in one section to form a timing tag at a start point and an end point.

On the other hand, when the digital audio data and the image data are synchronized and output, the image data is also divided by the timing tag stored in the timing tag file at the same time interval as the digital audio file.

The user interface 1 may be used in various ways depending on the medium to which the present playback apparatus is applied. In the case of a cassette, a CD player, an MP3 player, a DVD player, a video, and the like, the plurality of buttons formed for the user's selection input may be referred to as the user interface 1. In the case of reproducing data using a PC, as illustrated in FIG. 3, the reproduction screen 20 supported by a program and displayed on a monitor may be defined as the user interface 1. The playback screen 20 includes a video window 11 on which image data is displayed, a text window 13 on which sentences are displayed, and a control window 15 on which a plurality of buttons for controlling data are formed. The control window 15 includes a play button 21, a momentary stop button 22, a stop button 23, a repeat play button 25, a fast forward button 24, a rewind button 26, and a caption for reproducing data. The select button 29 and the like are formed.

Here, the repeat play button 25 is a button for repeatedly playing the digital audio file and the video file. When the repeat play button 25 is selected when the digital audio file and the video file are played, the control unit 10 Depending on which point of time between the start point and the end point of the current playback sentence of the digital audio file is selected, the current playback sentence or the sentence played immediately before the current playback sentence is repeatedly played.

On the other hand, in the memory 3, whether the current playback sentence is to be repeatedly played back or the immediately played sentence is repeatedly played in advance depending on at which point the repeat play button 25 is selected between the start point and the end point of the current playback sentence. It is set. For example, if the repeat play button 25 is selected before 1/2 of the play time during the playback of the current play sentence, the play played immediately before is repeated, and after 1/2 of the play time, the repeat play button 25 If you select), you can set to repeat the currently playing sentence. At this time, when the repeat play button 25 is selected in the previous half of the play time, that is, in the repetition chapter, the controller 10 stops playing the currently playing sentence and returns to the sentence played immediately before. After 1/2 of the playing time, that is, when the repeat play button 25 is selected in the current sentence repeat area, the controller 10 repeats the currently playing sentence after repeating the currently playing sentence. Play it. Of course, even when the repeat play button 25 is selected before 1/2 of the play time, the play of the sentence currently being played may be completed, and then the play may be returned to the play played immediately before. Here, the time ratio between the current sentence repeating region and the direct-text repeating region may be set in various ratios in addition to 1: 1, and may be arbitrarily determined by the user.

If the user selects any other button formed in the control window 15 while repeating the sentence as described above, the control unit 10 stops repeat play. That is, the selected sentence can be listened indefinitely repeatedly until another button is selected. At this time, of course, the number of repetitive reproductions may be set in advance. During the reproduction of the digital audio file, the control unit 10 drives the synchronization program 7, and the synchronization program 7 drives the video file in synchronization with the digital audio file using a timing tag.

With this arrangement, the process of repeatedly playing back the digital audio file and the video file using the present playback device is as shown in FIG. When the playback apparatus is driven to play the digital audio file and the video file (S10), as shown in FIG. 3, the controller 10 displays the playback screen 20 (S20). When the user selects the play button 21 (S30), the controller 10 drives the synchronization program 7 to synchronize the digital audio file and the video file according to the timing tag (S40), and then the video window 11 In step S50, the video data of the video file is reproduced, and the digital audio data of the digital audio file is reproduced, so that the text window 13 reproduces the sentence and also the sound (S50).

When the user selects the repeat play button 25 while the digital audio file and the video file are being played (S60), the controller 10 determines at which point of the sentence being played the repeat play button 25 is selected. (S70). If it is determined that the sentence played immediately before the currently playing sentence is to be repeated, that is, if the repeat play button 25 is selected in the direct field repeating area, the control unit 10 stops playing the currently playing sentence. Then, the process returns to the start point of the sentence played immediately before, and repeatedly plays the sentence played back immediately (S80). If the user selects the repeat play button 25 in the current sentence repeating area, the controller 10 continuously plays the currently playing sentence and when the currently playing sentence is completed, the currently played sentence is repeatedly played. It is made (S85).

Meanwhile, since the video file is also synchronized and output using the same timing tag as that of the digital audio file, the controller 10 controls the digital audio file to be repeated and simultaneously play the video file. Will be played repeatedly.

When the digital audio file and the video file are repeatedly played in this way, when the user wants to stop the repeat play, selecting any button formed in the control window 15 (S90), the control unit 10 stops the repeat play (S100). ). The controller 10 maintains the stop of the playback of the digital audio file and the video file when there is no user selection, and when the user selects the play button 21, the sentence that was last played before repeated playback. Return to the next sentence of the to resume normal playback.

In the case of repeat playback using this repeat playback method, not only the previous sentence but also the previously played sentence can be reproduced again. In other words, if the current sentence is playing, select the Repeat button in the repeating chapter of the directing chapter to play the repeating chapter, and if you select the repeat play button in the repeating section of the direct chapter during playback, The sentence will be played repeatedly.

Meanwhile, in the above-described embodiment, a digital playback medium for reproducing digital audio files and video files has been described. However, a repeat playback button 25 is also provided in a general playback device such as a cassette or a CD player. By providing a timing tag in the above manner, it is possible to perform repeat playback in a general playback apparatus.

As described above, according to the present invention, the data is divided into a plurality of sections such as a tape, a CD, a digital audio file, a moving picture file, and the like, and a timing tag is set in each section. Is selected, the currently played sentence or the sentence played immediately before is played repeatedly according to the time ratio of the selected point of the repeat play button 25 in the total playing time of the currently playing sentence. The selected sentence is continuously played back until another button is selected.

Accordingly, when the user finds a data section that the user wants to repeat, if the user selects the repeat play button 25, the user repeats the data of the section currently playing or the section played immediately before, so that only one repeat play button ( 25), it is possible to easily perform repeat play. In addition, as in the related art, it is possible to alleviate the inconvenience of repeat playback by setting the repeat playback section by the user. In addition, since the user can infinitely repeat the desired section as many times as the user wants, it is possible to solve the inconvenience caused when the user wants more or less if the number of times conventionally determined.

Meanwhile, in the above-described embodiment, only the case in which the object to be repeatedly played is audio data has been described. However, of course, the desired video may be repeatedly played during the playback of the video file.

In addition, in the above-described embodiment, the playback time of the currently playing sentence is divided by a predetermined time ratio, and the playback of the immediately preceding sentence is repeated before a predetermined time, and after the predetermined time, the currently playing sentence is repeatedly played. When the repeat play button 25 is selected, the sentence currently being played may be repeatedly played back unconditionally, or the sentence played immediately before may be repeatedly played.

As described above, according to the present invention, not only can the user repeatedly repeat the desired section the desired number of times, but also can easily perform the repeat playback operation.
