Database management method of moving picture experts group 1ayer 3 music file}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for managing a database, wherein the method of managing a database of an MP3 music file enables efficient management of a database containing MP3 songs by using ID3 (Identification 3) tag information in the MP3 music file. It is about.

In general, MP3 stands for MPEG Layer 3, which is one of the audio parts of MPEG technology. The MP3 is an audio file format created using audio data coding technology that can compress existing data to about one-twelfth without compromising sound quality. This makes it ideal for sending and receiving audio files using limited transmission lines. As such, the popularity of music-loving netizens is increasing significantly. In particular, MP3 allows users to use their PC as an audio system with a program that can make their favorite music into MP3 files, create their own albums on the PC, and play MP3 files.

On the other hand, such MP3 music is usually listened by inserting an earphone into a portable MP3 player, or through a computer equipped with a sound card and speakers. In addition, an MP3 player may be connected to a cassette player interface tape having the same shape as a cassette tape, and the interface tape may be inserted into a cassette player to listen to MP3 music through the speaker.

The method of downloading such MP3 music files from the Internet and playing them with an MP3 player is as follows. Of course, it must be downloaded for a certain amount through a specific website on the Internet that is already copyrighted and commercialized for MP3 music. First of all, a user needs a computer with a certain capacity capable of PC communication, a telephone line, a modem, related programs (Explorer, Netscape), etc., and needs to obtain an account of an ISP (Internet Service Provider) that can access the Internet. Do.

As the Internet develops, MP3 is the mainstream in multimedia music related to PC. Therefore, a supplier of MP3 music or a consumer with a large number of MP3 songs needs a dedicated MP3 database that can easily search for songs in various ways.

The technical problem to be achieved by the present invention is to provide a method for managing a database of MP3 music files so that it is easy to find a desired one of a number of MP3 songs by each information using the additional information area in the MP3 file.

1 is a flowchart illustrating an operation of a database management method of an MP3 music file according to the present invention.

FIG. 2 illustrates a user interface screen performing the method of FIG. 1.

3 to 8B illustrate an embodiment of the user interface screen illustrated in FIG. 2.

The method for managing a database of MP3 music files to solve the technical problem to be achieved by the present invention is a method of managing music files, the method comprising: (a) searching for a storage unit in which the music files are stored to search for an additional information area of the music file; Leading; (b) constructing a field-specific database using the read side information; And (c) searching and / or playing the desired music file according to the constructed database.

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

1 is a flowchart illustrating an operation of a database management method of an MP3 music file according to the present invention.

The method illustrated in FIG. 1 includes searching for a MP3 file by searching a folder or directory of a user PC (10), searching for each artist, title, album, genre, and year in an ID3 tag of each MP3 file and recording it in a database ( 11) creating a database (12), determining whether there is an MP3 file to add to the database (13), recording a new MP3 file (14) in the database, determining whether there is information to modify in the database Step 15, recording the modified information in the database (16), the user manages the MP3 file using the generated database (17).

FIG. 2 illustrates a user interface screen performing the method of FIG. 1.

Next, the present invention will be described in detail with reference to FIGS. 1 and 2.

The MP3 music file is divided into an audio area to be reproduced as music and an ID3 additional information area. The ID3 side information area consists of a music title assigned 30 bytes, an artist assigned 30 bytes, an album assigned 30 bytes, a year assigned 4 bytes, a comment assigned 30 bytes, and a genre assigned 1 byte. It is allocated 125 bytes in total.

By using this additional information area as a database for MP3 songs, it is easy to find the desired song by the desired information among numerous songs. In a system with a song database, service providers can manage MP3 files by building a database on their PCs and adding or modifying side information data directly as needed.

Search the folder or directory of the user's PC to find the MP3 file (step 10).

Scan MP3 files stored in a folder or directory of the user's PC to find MP3 songs, read ID3 additional information in the songs, search by artist, title, album, genre, and year and record them in the database (step 11). .

A database is created based on the recorded information (step 12). The database created by the additional information, the user can easily find the desired MP3 songs.

At this time, the MP3 song selected by the user is newly added to the folder configured above. Newly added NMP3 songs to the folder are searched by artist, title, album, genre, and year within ID3 tags and recorded in the database.

If there is information to be modified in the database, the modified information is recorded in the database (steps 15 and 16). The user can modify the artist, title, album, genre and year in the ID3 tag. When the user edits the area to be corrected, the information is updated with the user's modifications, and the process returns to step 11 and is recorded in the database.

The user retrieves and / or plays the MP3 file using the created database (step 17). When a user searches for MP3 files in the created database, the user can enter one of artist, title, album, genre, and year to find the desired MP3 file, and can immediately play and listen to it.

2 shows a user interface screen according to database management. In FIG. 2, when the user inputs a folder or a directory in which MP3 songs are collected, a set up scans the corresponding directory to find the MP3 song, and reads ID3 information in the MP3 song by artist, song title, album, and production year. Classify by star and genre to build database with each field. When the user selects a setup from the screen of FIG. 2, a database can be created.

The searched window shows all the ID3 information of the selected song in each field. When you double-click a listed song in this window, the song is played immediately.

Search does not find a song for each field, but finds a song directly by entering only one of the ID3 tag information. The user clicks Search and enters only one of the artist, title, album, year of production, and genre to find the desired song.

Add enters additional songs from other folders or directories into the database.

Modify will modify the record directly in the MP3 file and add it to the database if the managed location is different from the actual information.

The M3U (Music 3 unit) window is a format defined for continuous playback of MP3 playlist files. By selecting each song in the searched window, a playlist file can be created, which can be used by an external software player.
