Description

Display method of data in digital audio playback system {Method For Displaying Of Data In Digital Audio Playing System}

The present invention relates to a data display method in a digital audio reproduction system.

The most widely used digital audio reproduction system is the compact disc reproduction system. A typical compact disc stores about 1 to 2 hours of audio data, which is about 10 to 20 songs based on a song or pop song. When playing back the audio data stored in the compact disc, the serial number of the audio data currently being played is shown on the display section of the compact disc playback system, and the user recognizes the audio data currently being played through this number.

In addition to such a general compact disc, there is an MP3 reproducing system capable of reproducing audio data of a compressed MP3 file. When stored as an MP3 file, about 150 pieces of audio data can be stored in a general compact disc. In the case of storing and reproducing the audio data stored as the MP3 file as described above, it is very inconvenient for the user to recognize the audio data if the audio data is displayed as 150 serial numbers without a systematic storage method and a display method accordingly.

In the case of a conventional compact disc playback system or MP3 playback system, as described above, when the number of audio data stored is large, the audio data is stored in the serial number order and the reproduced audio data is represented by the serial number. There is a problem that a user cannot conveniently select and play desired audio data.

In addition, since the conventional MP3 playback system does not use the ID3 Tag information of the MP3 file, it is not possible to select a file for each classification using the information of the audio data included in the ID3 Tag. The ID3 Tag of the MP3 file stores information such as a title, a singer, an album, a year of publication, a genre, and the like. According to the related art, it is impossible to select audio data by artist or genre.

The present invention is to solve the problems of the prior art as described above, an object of the present invention is to systematically store when a large number of digital audio data is stored and to allow the user to easily select the desired digital audio data A data display method in a digital audio reproduction system is provided.

In order to achieve the above object, the data display method in the digital audio reproduction system according to the present invention comprises the steps of: storing the audio data files of the MP3 compression method in a directory structure; Displaying an upper directory and the number of directories and files included in the upper directory on a display unit of a reproduction system; And displaying the sequence number and the reproduction time of the currently selected directory or file.

Hereinafter, a method of displaying data in a digital audio reproduction system according to the present invention will be described in detail with reference to the accompanying drawings.

1 shows an example of a data storage method in a data display method in a digital audio reproduction system according to the present invention.

As shown in Fig. 1, in the present invention, files in many MP3 file formats are stored in a directory structure. For example, files are categorized by parent directories such as song, ballad, pop song, heavy metal, etc., and in the parent directory called 'song', they also have sub-directories such as dance and ballad, and hierarchical status equivalent to the sub-directories. The files (file10.mp3, file11.mp3, file12.mp3) belong. In addition, sub-directories such as dance and ballads classify files belonging to each.

The storage form of the MP3 files having the directory structure as shown in FIG. 1 may be arbitrarily classified by the user or may be automatically classified using the ID3 tag of the MP3 file. The ID3 Tag of the MP3 file can store data of six fields: title, artist, album, year of publication, genre, and comment. Therefore, files can be classified by the six fields.

2 shows an example of a data display method in a digital audio reproduction system according to the present invention.

As shown in Fig. 2, the display section includes not only the currently selected operation mode but also information on the directory structure of the files included in the compact disc, and the playing time which is the elapsed playing time when the currently selected directory, file or file is being played. To display. The case shown in FIG. 2 will be described in detail.

The top row of '1 song D 2 and F 3' contains two sub-directories and three files with the same hierarchical status as the sub-directory in the 'K-pop' directory, which is the first directory among the files stored in the directory structure. To indicate that.

'2D Ballad 0:00', the main line of the display, is the second directory among the subdirectories included in the 'Ko' directory, which is the first directory displayed first, and the directory name is 'Ballard'. . On the other hand, since the 'ballard' directory is not a file to be played, the playing time is 0:00. In the display section, this part may be represented as a file having a hierarchical status equivalent to a subdirectory 'ballard'. Referring to FIG. 1, files 10.mp3, file 11..mp3, and file 12.mp3 are such. to be. Therefore, if file 12.mp3 is selected, the main line may be displayed as '3F file 12', which means that it is the third file among the files contained in the 'Ko' directory, which is the first directory listed first, and is the file name. Is to mark 'file12'.

Based on the display method described above, a file desired by a user can be easily selected by moving between directories or between files.

First, when a compact disc having files stored in the directory structure as shown in Fig. 1 is inserted into a reproduction system, it is initially located in the root directory. Since the root directory has three parent directories of song, pop song, and heavy metal, and there are no files, the root line of the display showing the directory structure is 'root D 3, F 0'. In the main line, the first parent directory of the root directory, the flexible directory, is selected as the initial setting, and the display shows 'flexible'. In this initial state, when the user presses the '→' key (right key), the main line changes to the next higher directory 'pop song'. When the user presses the '→' key once more, the main line changes to the next higher directory 'heavy metal'. Also, when the main line is 'Ko', pressing '↓' (down key) will make the top line 'Ko' and the song directory has 2 sub directories and 3 files, It is indicated by F 3 ', and in the main line, the dance directory, which is the first subdirectory of the flexible directory, is selected as the initial setting. At this time, if the user selects the 'play' function, files 3.mp3, file 4.mp3, and file 5.mp3, which are files stored in the 'dance' directory, are played in this order. If the user presses the '→' key while the 'Dance' directory is set on the main line, the next subdirectory 'Ballard' is selected, and if the '→' key is pressed continuously, the 'Dance' subdirectory and ' File 10.mp3, File 11..mp3, and File 12.mp3, which have hierarchical status equivalent to Ballard 'subdirectory, will be selected in this order. In addition, if the user presses the '↓' key while the 'ballard' directory is set on the main line, the upper line will be displayed as 'ballard, D 0, F 3' and the 'line 7' will be displayed on the mail line. Press '→' key to select file 8 or file 9.

In summary, moving between directories or files with the same status is moved by '→' key (right key) or '←' key (left key), and it is possible to select a file included in each directory. You can use the '↑' key (up key) or the '↓' key (down key) to move to the hierarchy.

In order to move between directories or files, the method shown in FIG. 3 may be used.

According to the scheme shown in Fig. 3, the names of subdirectories and files included in the current directory are displayed on the display unit. If the name you want to display is a directory, mark it with a D before the name, or F if a file. 3 shows the 'song', 'pop song' and 'heavy metal' directories included in the root directory. The user selects the desired directory by moving the cursor. For example, when the user selects the 'pop song' directory, the display portion changes as shown in FIG. In FIG. 4, since a parent directory exists above the currently selected 'pop song' directory, '↑' is displayed to move to the parent directory, and 'directory 14', which is the first directory of the 'pop song' directory, is a directory. Although the files in the directory 14 are displayed, only the first file 'file 15.mp3' is displayed in FIG. 4 since the number of lines that can be displayed in the display unit is limited. When the user presses the '↓' key, the content of the display scrolls to show the remaining files.

According to the method shown in Figs. 3 and 4, adjacent pies in the same directory as the current file can be easily identified, and the user can use the '↑' and '↓' keys and the select button on the display unit to display between directories or files. You can perform a liver movement.

5 illustrates a directory listing method. The directory listing method shown in FIG. 5 is to list all directories included in the compact disc regardless of hierarchical status. In FIG. 5, if the ballad is selected, the display unit lists the files included in the ballad directory. If there are many items to list, the scrolling method allows the user to select a directory or file to be scrolled from the display using the '↑' or '↓' key.

In addition, the display method in the audio data reproduction system according to the present invention can use the information of the ID3 Tag of the MP3 file. As described above, the ID3 Tag information of the MP3 file can be used. As described above, the ID3 Tag of the MP3 file stores data of six fields such as title, artist, album, year of publication, genre, and comment. When the user selects the information display function using the ID3 tag, a menu as shown in FIG. 6 is displayed on the display unit. Here, for example, selecting 'singer' lists the corresponding field values for all files stored on the compact disc. If you select a file from the listed files, the files with the corresponding field values are played in order.

As described above, the data display method of the digital audio data reproducing system according to the present invention systematically stores a large number of digital audio data stored therein and enables a user to easily select desired digital audio data.
