Hereinafter, a method of playing a mapped audio file or a video file in a mobile terminal having a touch screen according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the portable terminal according to the present invention has a schematic configuration of a display unit 11, an input unit 12, a control unit 20, a communication module 30, a memory 40, and an audio player 51. , A video player 52, an audio device 60, and the like.

The display unit 11 displays caption data and image data processed by the caption processing unit 22 and the video processing unit 23 of the control unit 20 on a screen such as an LCD and an LED. The display unit 11 in the present invention is provided as a touch screen for inputting a signal to operate as the input unit 12.

The input unit 12 receives a user's operation signal for controlling the operation of the portable terminal, and in the present invention, a touch screen as the input unit 12 for inputting a control signal for playing an audio file or a video file in the portable terminal. It includes.

The controller 20 performs a function of controlling the overall operation of the portable terminal, and includes an audio processor 21, a caption processor 22, and a video processor 23 inside the controller 20.

The communication module 30 is for performing a wireless communication function with the outside, and is composed of an antenna, an RF transmitter, an RF receiver, and the like.

The memory 40 stores a program downloaded from a mobile terminal or the like through a wired / wireless communication network (including the Internet). Patent The present invention downloads and stores a mapped audio file or video file.

The audio player 51 may play an audio file (MP3, WAW, etc.) including the subtitles. When the audio player 51 plays the audio file including the subtitles, the sound source may be a speaker or an earphone. The subtitles are output to the audio device 60 configured as shown in FIG. 11.

The video player 52 may play a video file including subtitles (AVI, MPEG4, WMV, ASF, etc.), and when the video player 52 plays the video file including the subtitles, the sound source may be used. The audio device 60 is configured as a speaker or earphone, and the caption and video are displayed on the display unit 11.

The audio file and the video file to be applied in the present invention are mapped audio files or video files, wherein the mapped audio file is divided into section information units such as measure units, word units, sentence units, etc. in the contents of the audio file. Pre-mapped file. For example, when the mapped audio file includes subtitles in an audio file for language learning or song practice, the mapped audio file is divided and mapped into interval information units such as measure units, word units, sentence units, etc. according to the intention of the mapping producer. In this case, the sound source synchronized with the subtitle is also distinguished.

In addition, the mapped video file refers to a video file that can be used for movie watching, language training, or training exercises such as golf, volume dance, yoga, etc., among scenes, sound sources, and subtitle signals of the video. It selects and divides a specific range into sections, and maps the starting and ending points of each divided section by section information unit. For example, in the case of a movie video, a movie scene to be classified is determined by the section information unit of the video, and when the movie scene is changed or when the movie scene is long, a scene in which a specific actor appears on the screen, or a love scene is determined. The same scene can be determined in advance. Of course, the classification of such a movie scene may refer to a scenario or the like, and the mapping producer may arbitrarily determine an optimal section.

The technique of mapping a video is described in detail in Patent Application No. 1999-55065, etc., which was invented by the inventor, and thus will be omitted here.

Next, the method of repeating the section in the present invention will be described with reference to FIG.

First, a user may download a mapped audio file or a mapped video file divided into section information units through a wired / wireless communication network (including the Internet) and store them in the memory 40.

The user executes the audio player 51 or the video player 52 in his mobile terminal, and plays the mapped audio file or the mapped video file by dividing it into the section information units stored in the memory 40 (step S11). ).

At this time, when the mapped audio file is played, a control key ▷ is displayed on the touch screen together with a subtitle, and a sound source is output to the audio device 60. Meanwhile, when the mapped video file is played, a control key (rewind (Rew Re), play or pause key (∥ or ▷), FF (▷▷) key) is displayed on the touch screen together with the video and subtitles. The sound source is output to the audio device 60.

When the mapped audio file or the mapped video file (hereinafter referred to as 'mapped file') is played, if the user touches the repeat play operation on the touch screen, the mapped file is switched to the repeat play mode. And, the section of the time point when the repeat playback operation touch on the touch screen is repeatedly played. Here, the section repeating playback process is repeated from the beginning of the section of the time point when the section repeat touch on the touch screen is repeatedly played (steps S12, S13, S15). Preferably, the repetitive playback operation touches the touch screen twice in quick succession to be distinguished from other operation touches.

When the user switches to the repeat play mode and the user repeatedly touches the section on the touch screen while the specific section of the mapped file is repeatedly played, the repeat play mode is released and the next section of the specific section is played ( See steps S17 and S19). Preferably, the section repeat release touch simply touches the touch screen once to distinguish it from the repeat play operation touch.

If there is no section repetition releasing touch on the touch screen in a state where the specific section of the mapped file is repeatedly played back in the repeat play mode, repeat play of the specific section is continued (step S18). At this time, if you press the pause key (∥) during repeat section playback for your convenience, it is possible to pause during repeat section playback.To return to the section repeat playback of the section, touch the touch screen once or press the play key (▷). Press to resume playback.

On the other hand, when the mapped audio file or the mapped video file is played, if there is no repeat play operation touch, the mapped file is continuously played without repeat play as in the normal play mode (step S14).

Next, a method of reproducing the next section and the previous section in the present invention will be described with reference to FIGS. 3 and 4.

First, a user may download a mapped audio file or a mapped video file divided into section information units through a wired / wireless communication network (including the Internet) and store them in the memory 40.

The user executes the audio file player 51 or the video player 52 in his portable terminal, and reproduces the mapped audio file or the mapped video file by dividing by the section information unit stored in the memory 40 (S21). And step S31).

At this time, when the mapped audio file is played, a control key (rewind (Rew ◁◁), play key or pause key (▷ or ∥), FF key (▷▷)] is displayed on the touch screen together with the subtitle. The sound source is output to the audio device 60. On the other hand, when the mapped video file is played, a control key (rewind (Rew), play key or pause key (▷ or ∥), FF key (▷▷)] is displayed on the touch screen together with the video and subtitles. The sound source is output to the audio device 60. The sound playback device of most smartphones and tablet PCs currently on the market is not played when the FF key (▷▷), which is a control key, is switched to the next section of the mapped audio and video file currently being played, but the next video is played. The playback speed will be converted to a file or audio file, or the playback speed will be faster in the fast forward direction. Also, pressing the Rewind key will switch to the previous section of the mapped audio and video file currently being played. Rather than being played, the playback speed is faster in the direction of playing or rewinding the previous video file or audio file.

As shown in FIG. 3, when the mapped audio file or the mapped video file (hereinafter, referred to as a “mapped file”) is played, the next section operation touch is performed on the touch screen when the user wants to play the next section. In this case, the first part of the next section of the current playback point is played (steps S22 and S23). When the user continuously touches the next section operation on the touch screen while the first section of the next section is reproduced on the touch screen, the first section of the next section is reproduced (steps S24 and S25). ). The next section operation touch may be such that the user touches the finger on the touch screen (touches) and slides to the left (or right) as if turning the next page with a finger in a book so that the user can easily understand. (This type of operation is commonly referred to as touch and slide).

However, if there is a section to be searched in the video file or audio file being played back (for example, the 18th section), the user may have inconvenience to perform the next section operation touch 17 times in order to search for the section. have. In order to solve this problem, when the user continuously touches the next section operation twice or three times, the controller of the portable terminal may automatically recognize the signal to skip the next section and perform the automatic next section turning function. At this time, if the user wants to stop the function while performing the automatic next section turning function, the user can stop the function with a single touch.

If the mapped file is played, if there is no next section operation touch, the mapped file is continuously played in the same manner as in the normal playback mode (step S26).

Meanwhile, as shown in FIG. 4, when the mapped file is played, if the user touches the previous section operation touch screen on the touch screen when the user wants to play the previous section, the first part of the previous section of the current playback point is displayed. Is reproduced (steps S32 and S33). If the user continues to touch the previous section on the touch screen while the first section of the previous section is reproduced on the touch screen, the first section of the previous section is reproduced (steps S34 and S35). ). The previous section operation touch moves the user's finger to the touch screen (touch) and slides to the right (or left) as if turning a previous page with a finger in a book so that the user can easily understand (touch and slide) It is desirable to

In the previous section operation touch, as shown in the next section operation touch, when the user touches the previous section operation 2-3 times in a row, the controller of the portable terminal automatically recognizes the signal to skip the previous section and performs the automatic previous section skipping function. It can be done.

If the mapped file is played back, if there is no previous section operation touch, the mapped file is continuously played in sequence like the normal playback mode (step S36).

As described above, according to the present invention, an audio file or a video file producer is divided into section information units to produce a mapped audio file or a video file, and provide the mapped audio file or a video file to the user's mobile terminal. In playing the mobile terminal, it is very easy to repeat playback of sections based on the section information unit previously determined by the file creator, and it is possible to easily search or play the next section and the previous section. There is an advantage that can be utilized in a variety of exercises, such as singing exercises and exercise exercises, such as golf, tennis, yoga, volume dance.

For example, in the case of language learning, if you listen to a native speaker and practice speaking or studying conversation, the author of the textbook maps the section to the best section for learning and displays the subtitles for each section. Not only can you find a section easily and quickly, but you can easily skip to the next section immediately. In this case, a smartphone or tablet PC equipped with a touch screen can be immersed in learning because it is easy to operate by simply searching the sections before and after or by simply replaying a predetermined section during playback with a double touch type with a simple touch-and-slide method. Easy to play, learning efficiency increases, and the time for unnecessary operation is shortened, so that the entire learning time is greatly reduced, so that the master can be mastered in a short time.

In addition, an example of video learning to which the present invention may be applied may include video problem solving videos of mathematics and sciences.

Participants' problem is that there is no way to skip it at once when it comes to knowing problems, and it is very time consuming to turn the screen quickly so that the screen can pass. This manipulation makes it difficult for students to be distracted and immersed. In addition, once you hear a problem solving that you do not understand well, you have to listen once more. At this time, you find the beginning of the problem solving image and turn the screen quickly to find the end. The problem is that there is a problem that greatly reduces the learning efficiency by causing irritation and immersion in the study, so in order to solve this problem, the sections are pre-mapped and pre-mapped for each problem to solve the video. If you can bet the learning efficiency of the user can be greatly increased.

In addition, the present invention provides a method of searching for a section having a measure or a dance movement that is difficult to practice or replaying a found section while playing a song or dancing while playing MP3 music or a music video video in which a subtitle of a singer is displayed. The present invention is useful for users who play all videos that need to watch and listen to the instructor's explanations and practical skills such as yoga taekwondo kung fu or acupuncture, which is very useful, and it is important to repeatedly practice posture and movement such as putting and swinging golf. 'S simple navigation and looping technology encourages users to recognize the entire audio and video file in sections, allowing users to skip sections that they already know, and quickly searches for sections that require repeat exercises. It's much faster and more accurate than the way you play. Subtitle display audio also has the advantage of navigating in subtitle units while viewing the screen.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
