The present invention relates to a method and system for providing a music-related information providing service function using an audio gene. In particular, the present invention provides music information for file identification and classification to an audio data file such as a music file through an online network such as an internet network. The present invention relates to a method and system for providing music information through audio gene generation and transmission that provides music information to a file.

In addition, the present invention has a function that can play music files, and also has the function to recommend the best music to the user, automatically using the music information providing method through the generation and transmission of the audio gene automatically It relates to a system that can be classified and filed in a hierarchical or directory structure.

In addition, in the present invention, when playing music using a function of a music player embedded in a communication device such as a mobile phone, the music fee is calculated using the audio gene of the music data being played, thereby accurately calculating the intellectual property rights. It provides a way to do it.

In general, a music CD simultaneously stores music information such as a song name, album name, singer, track information, and playing time of an audio file along with the audio file. This information is commonly called a header information or a meta database. do. Therefore, when the music CD is played by a player such as a Windows media player or a dedicated player with a display window, the music information such as the copyright, track, song name and artist name described above for the audio file being played back, i.e., the music file, is simultaneously displayed. Is displayed to provide the user with information about the audio file. Therefore, if the music information itself is not stored or if some music information is lost or if wrong music information is stored, information on the audio file being played cannot be known at all.

Typically, since only about 12-15 music files are stored in a single music CD, the user must frequently replace the music CD to continuously listen to new music. Therefore, there is a significant inconvenience from the user's point of view, in particular, from the user's point of view of using the music CD in the vehicle.

However, with the development of data compression technology, the wave-type music files and the audio files of all audio compression file formats such as MP3, ogg, aac, etc. are compressed, and MP3 (MPEG Audio Layer-3) is provided. Many audio files are provided as file formats. As described above, the music file of the MP3 format may contain about 130 to 250 songs in one CD. Therefore, many music CD owners convert the music files stored in the music CDs into MP3 files, and convert them into wave-type music files and compressed audio files such as MP3, ogg and aac. However, when converting a music file into a wave-shaped music file and all audio compressed file formats such as MP3, ogg, aac, etc., the header values stored in the meta CD of the music CD are not converted at the same time. There was no knowledge of the type of music files and the audio files that were converted to all audio compressed file formats such as MP3, ogg, aac, etc.

In addition, even when users download and use wave-type music files and all audio compressed files such as MP3, ogg, aac, etc., which are compressed or paid through the Internet, there are many cases in which there is not enough file information.

In addition, when recording live music and converting it into a wave-type music file and all audio compressed file formats such as compressed MP3, ogg, aac, etc., the user directly creates and attaches an ID3v2 tag file for the music. There was only inconvenience.

Therefore, while providing music information data for audio files automatically to MP3 files that do not have accurate music information for audio file data, the data can be tagged with ID3v1 or ID3v2 tag formats and sorted automatically. It is desirable to provide.

As such, the method for identifying all audio data files without file data is filed on February 6, 2004, filed by the applicant of November 2004, which provides information about the audio data file via the ARS function of the telephone. It is described in Korean Patent No. 456408 (audio gene generation method and audio data retrieval method) registered as a date, the contents of which are used for reference throughout the present invention.

Meanwhile, with the development of semiconductor technology, since the advent of semiconductor lasers, music that has been distributed through LP or magnetic tapes has been provided through CDs, providing a cleaner sound quality without noise. However, even when music was distributed through CDs, many musics could not be provided on one CD. However, since the MPEG-Audio Layer 3 (hereinafter referred to as MP3) standardization of the voice compression technology has been standardized by the Video Expert Group (MPEG), a lot of softwares for generating MP3 files have been created, and thus MP3 files can not be played back. Many playback devices, so-called MP3 players, are commercially available. Music files produced as MP3 files were considerably smaller than music files provided on general CDs and could be stored in one CD. In addition, along with the development of flash memory, MP3 players using flash memory as a storage medium have emerged. Also, MP3 players using mini hard disks are being produced due to the development of hard disks. In addition, as capacity increases and circuit technology or software technology develops, a lot of MP3 players, which also serve as portable storage devices, are being produced.

In general, when the flash memory is used, the storage capacity of most is 125M to about 1G, when using a mini-disk is currently up to 20G or more. As such, users use a large amount of storage media to store many MP3 music files in the MP3 player. However, since there are many music files, it is very difficult to find the music that the user wants. Also, in order to find the music file that the user wants, the directory is formed in the MP3 player, and then the music is stored in a hierarchical structure. It is easy to find. However, this is not only cumbersome depending on user manual work, but also requires considerable time.

However, even in such a case, in order to find the desired music, it is necessary to manually find and play the desired music. This inconvenience is described as an example of an MP3 player which is a portable storage device, but the same applies to a device that typically stores and uses files such as MP3 file music files, that is, a computer, a PDA, a mobile phone, a DMB phone, and the like.

Accordingly, music such as an MP3 player having a system that can be attached to an MP3 file and automatically form a folder for each information data based on the tag's information data, and then store and store the MP3 files in a hierarchical or directory structure. It would be desirable if a playback device could be provided.

In addition, it would be desirable to be able to provide a music player such as an MP3 player having a system capable of providing an optimized MP3 music file to the user according to the user's taste or the condition of the day.

On the other hand, communication devices such as mobile phones are currently provided with a function of playing music data such as MP3, so that many users enjoy music through mobile phones, and also telecommunication companies provide music. In addition, users can download illegal music data for free through the Internet using a computer or convert music contained in music CDs into music files such as MP3 files, and then download them to a mobile phone to enjoy music. In using music data, providing music fee is not a problem, but now most of the music is illegally downloaded and used through the Internet, and accordingly, there is a lot of financial loss of music data holders and As it is not protected, the music market is shrinking a lot.

Therefore, music data owners, such as record producers, monitor the distribution of illegal music data through continuous monitoring to protect their rights, but it is not easy to crack down, and MP3 via mobile phones to telecommunication companies that provide MP3 music files. Even if you ask for the music file to be discontinued, you can't stop it easily due to the interests of the telecommunications company.In addition, users download and use illegal music through the computer rather than download and use the music through the telecommunications company. This is also almost impossible to crack down.

Therefore, it is possible to accurately recognize the music file played through the mobile phone, so even if the music file stored in the mobile phone illegally downloaded or copied files and methods that can collect the exact cost of using the music file It would be nice if you could provide.

According to a first embodiment of the present invention, a method and a system for providing collective music information by using an audio gene generation method and an audio data retrieval method are as follows.

3 is a diagram illustrating a schematic configuration of a system for providing a batch of music information through an online network according to a first embodiment of the present invention, and FIG. 4 is a diagram of a batch of music information through an online network according to a first embodiment of the present invention. This is a flowchart showing how to provide.

Referring to FIG. 3, a system 1000 for implementing a method of providing collective music information through an online network according to the present invention is largely comprised of a user device 100, a user application 200, and a music recognition platform 300. And the Internet network 400 for connecting the user device and the music recognition platform online.

The user device 100 converts a music file recorded in a music CD into a wave-shaped music file and all compressed audio files of compressed MP3, ogg, aac, and a wave-like music file online. And a device that downloads all compressed audio files such as MP3, ogg, aac, etc. which are compressed, or receives live music and converts them into MP3 files. The device may be a general personal computer or a dedicated hardware device. As shown in the drawing, the user device 100 downloads a wave-shaped music file and all audio compressed files such as MP3, ogg, aac, etc., which have been compressed or paid online for free (510). By using a device such as a CD-ROM drive and a wave-type music file and all audio compression file conversion programs such as MP3, ogg, aac, etc., the music files stored in the music CD are compressed Convert all audio compressed files such as MP3, ogg, aac (520) or live audio data input through a voice input device such as a microphone, that is, live music to wave-shaped music files and compressed MP3, ogg, All audio compressed files such as aac are converted (530).

Wave-type music files provided by professional music providers such as record labels and all audio compressed files such as MP3, ogg, aac, etc. that are compressed have ID3v1 tag or ID3v2 tag, and ID3v1 tag contains track / title / artist / album Information such as name / genre / detail information is attached, and ID3v2 tag is attached with information such as composer / lyrics / original artist / copyright author / URL / encoded person, and the corresponding wave-shaped music file and MP3 compressed You can check the details of all audio compressed files such as ogg and aac in detail.However, you can check the detailed information as described above for free or paid wave music files and compressed audio files such as MP3, ogg and aac. There may be no tag information. In addition, when converting a music CD music file into an MP3 file or converting live audio data into a wave-shaped music file and all compressed audio files such as compressed MP3, ogg, aac, etc., the tag information as described above. There will be no at all.

The user application 200 is a music recognition platform through the Internet network 400 to the various wave-shaped music files and MP3, ogg, aac and the like compressed audio files input through the user device 100 300, a hardware type may be installed in the user device or a software type in the user device. In addition, the user application receives information data about the wave-shaped music file transmitted from the music recognition platform 300 and all audio compressed files such as MP3, ogg, aac, etc. that are compressed and attached to the files. It also classifies MP3 files into a hierarchical structure based on the information data.

The music recognition platform 300 is a wave-shaped music file and all audio compressed file recognition and search server 310, such as MP3, ogg, aac, and the like compressed, music DB 320 for storing all the music data that can be collected And an optional music sampling data DB 330 and a music information DB 340. The music recognition platform is a key value by an audio gene value or a hash algorithm generated from a wave-shaped music file transmitted from the user application 200 and all audio compressed files such as MP3, ogg, aac and the like compressed. Alternatively, ID (ID), code (CODE) received by the wave-shaped music files and compressed audio files such as compressed MP3, ogg, aac, etc. and the search server 310 based on the music DB (320) If a matching file is found, the music information data of the file is retrieved from the music information DB 340 and transmitted to the user application. Then, the user application attaches the music information data to the wave-shaped music file and all audio compressed files such as MP3, ogg, aac, etc., which have been compressed.

In the case of retrieving the music information data by transmitting a wave-shaped music file and all audio compressed files such as MP3, ogg, aac, etc., the wave-shaped music file and all audio such as MP3, ogg, aac, etc. Due to the large size of the compressed file, it takes a long time to transfer and a little time to search. Therefore, rather than transmitting all of the wave-shaped music files and all audio compressed files such as MP3, ogg, aac, etc. that have been compressed, using the audio gene generation and storage steps (S20) described in steps S18 to S28, Samples of music files and compressed audio files such as MP3, ogg, aac, etc., are sampled to generate audio DNA, or a key, ID, or code is generated through a hash algorithm. In addition to shortening the time, the search time may also be shortened. Accordingly, the wave-shaped music file and all audio compressed files such as MP3, ogg, aac, etc., compressed by the user application 200 are sampled over several sections, and the key and ID are generated by the audio DNA or hash algorithm generated by sampling. Alternatively, when the codes are transmitted to the music recognition platform 300, the music recognition and search server 310 searches for matching data based on the music sampling data DB 330. If there is matching data, the music information data related to this is retrieved from the music information DB 340 and transmitted to the user application, and the user application sends the music information data to the music file of the wave form and the MP3, ogg, All audio archives, such as aac, are tagged. The reason for sampling wave-shaped music files and all audio compressed files such as MP3, ogg, aac, etc. compressed over several intervals is to improve the accuracy of the search.

The user application 200 not only attaches music information data to the corresponding MP3 file, but also hibernates the music file in wave form based on the music information data and all audio compressed files such as MP3, ogg, aac, etc. Directory structure). That is, wave-type music files and all audio compressed files such as MP3, ogg, aac, etc. that are compressed are track / title / artist / album name / genre / details / composer / lyrics / original artist / copyright / URL / encode The information is classified according to the information of one person and stored in a predetermined storage device, for example, the storage device 110 of the user device. In this case, the storage device of the user device may be a hard disk such as a computer and may be a portable storage device such as a wave-shaped music file and all audio compressed file players such as MP3, ogg, aac, etc., which are compressed.

In the above, the system 1000 for implementing the music tag providing method through the online network according to the present invention has been described based on the user device 100 which is a personal computer connected to the internet network 400. Any device having a communication function, such as a portable terminal capable of communicating, a PDA phone, or a digital multimedia broadcasting (DMB) phone having a communication function, can be used as the user device 100. That is, the user application 200 according to the present invention can be embedded in a device having a communication function as described above. In this case, as described above, the user application may be built in hardware or embedded in software. In addition, by installing a communication port such as a USB port for wired communication or wireless communication in a portable storage device such as an MP3 player, and also embedding the user application, it is understood that the MP3 player can also be used as the user device 100. Those skilled in the art will understand well.

4 is a flowchart illustrating a method of providing a music tag through an online network according to a first embodiment of the present invention.

Hereinafter, a music tag providing method through an online network will be described in detail with reference to FIGS. 3 and 4.

First, the music file recorded on the music CD through the user device 100 is converted into a wave-shaped music file and all audio compressed files such as compressed MP3, ogg, aac, etc. are generated, or paid or free online. Download wave-shaped music files and all audio compressed files such as MP3, ogg, aac, etc. that are compressed, or receive live audio data, that is, live music, through an input device such as a microphone, and compress the wave-shaped music files All audio compressed files such as MP3, ogg, aac, etc. are generated (step S100). At this time, the generated wave type music file and all audio compressed files such as MP3, ogg, aac, etc. which are compressed are missing or not enough file information, so "ABC.mp3 or track01.mp3, track02.mp3, track03.mp3" and File names of the same format will be created. Key value, ID, code by audio gene value or hash algorithm generated from wave-shaped music file and all audio compressed files such as MP3, ogg, aac etc. The value is transmitted to the music recognition platform 300 through the user application 200 and the Internet network 400 (S110). Then, whether the music recognition platform music recognition and search server 310 has the same music as the wave-shaped music file received and all audio compressed files such as MP3, ogg, aac compressed and the like, in the music DB 320 The search is performed based on the stored data (S120). If there is a music match, music information data that matches the music, for example, " song name: make-up, singer: WAX, album: WAX2 collection, genre: ballad " It becomes (S130). Then, the music information data is transmitted to the user application (S140), and the music information data is informed whether the correct music information (S150). In most cases, users can know whether the music information is accurate because they know the wave-shaped music files they want to use and all the audio compressed files such as MP3, ogg, aac etc. If the music information is not correct, the flow advances to step S120 to perform a search again and transmits the music information data to the user application again. If it is determined that the music information is correct, the " song name: makeup " is applied to an incorrect wave-shaped music file such as "ABC.mp3 ???" and all audio compressed files such as MP3, ogg, aac, etc. The music information data such as artist: WAX, album: WAX2 collection, genre: ballad, and the like is tagged (attached) (S160). Then, the file name "ABC.mp3 ???" is changed to "Fixing the makeup.mp3", and if there is a display screen during playback, the display screen "Song name: Make-up, singer: WAX, album: Music information data such as WAX2 collection, genre: ballad, etc. are displayed.

Then, the user application 200 is a hierarchical structure (directory) based on the music information data of the wave-shaped music file tagged music information data and all audio compressed files such as MP3, ogg, aac, etc. Structure) to automatically generate a hierarchical structure for filing, that is, classification (S170). For example, assuming classification by artist, genre, etc., the file "Fixing the makeup.mp3" can be checked in the artist name folder "WAX" in the artist name directory because "WAX" is tagged. Since "Ballard" is tagged, you can check the file "Fixing the makeup.mp3" in the "Ballard" folder in the genre directory. In addition, since "WAX2 collection" is tagged, it is possible to check the "mp3" file by fixing the makeup in the subfolder "WAX2 collection" in the "WAX" folder in the artist-specific directory. In other words, through the entire directory structure according to the tag value, it is possible to check and play the wave-shaped music files and all audio compressed files such as MP3, ogg, aac, etc. which have been compressed.

As such, when the file classification is completed, the data is stored in a predetermined storage device, i.e., a portable storage device such as a computer hard disk or wave-shaped music file and all audio compressed file players such as MP3, ogg, aac, etc., which are compressed.

In the above, the user application 200 through the Internet network 400, the wave-shaped music file and the audio compression files, such as MP3, ogg, aac and the like to find the music information data that you want to find music platform 300 ) To be sent. However, as described above, wave-type music files and all audio compressed files such as MP3, ogg, aac, etc., which are compressed are generally large in file size, so it takes a long time to transfer and file recognition and search server in music recognition platform. The search at 310 also takes some time. Therefore, when there are many users, a big load may be applied to a search server. In order to solve such a problem, after the file generation step (S100), the user of the wave-shaped music file that you want to find a music information file in the application and compressed audio files such as MP3, ogg, aac, etc. Sampling is performed to generate keys, IDs or codes by audio DNA or hash algorithms. Then, the key, ID or code by the audio DNA or hash algorithm is transmitted to the music recognition platform (S110), and the file recognition and search server 310 of the music recognition platform sends the sampling data to the music sampling data DB 330 The comparison is made with the music sampling data stored in the), and then a matching music file is found. Then, the music information data is retrieved from the music information DB 340 and transmitted to the user application, and the user application stores the music information data in a wave-like music file and compresses the MP3, ogg, and the like as described above. It attaches to all audio archives such as aac and also performs a hierarchical structure (in directory structure).

As described above, according to the present invention, the music information data is not only provided to the wave-shaped music file in which the music information can be confirmed and all audio compressed files such as MP3, ogg, aac, etc., which are compressed, and the music information data in the MP3 file. It is also possible to attach a wave-type music file and all audio compressed files such as MP3, ogg, and aac based on the music information data.

In the above description, a wave-shaped music file without tag information and all audio compressed files such as MP3, ogg, aac, etc. which have been compressed are described. However, the present invention can be applied to all file formats requiring an information data tag. Should know.

5 to 7 are views for explaining a second embodiment of the present invention.

FIG. 5 may classify and store a data file in a hierarchical or directory structure based on file information data of a tag attached to all data files such as MP3, ogg, aac, etc. according to the second embodiment of the present invention. At the same time, the data file can be classified into a hierarchical or directory structure based on the updated file information data of the tag, and the data file is optimized according to the physical and mental conditions of the user. That is, it is a diagram schematically showing a system that can recommend all music files such as MP3, ogg, aac.

Referring to FIG. 5, in the second embodiment of the present invention, the system 2000 includes a central control unit 2110, storage means 2120 for storing all music data files such as MP3, ogg, aac, and the like. Tag filtering means 2130 for filtering the data file to which the data file is attached based on the file information data of the tag, and classifying the data file into a hierarchical structure or a directory structure and storing the data file in the storage means, and MP3, ogg, aac, etc. A communication port 2140 such as a USB port, an infrared port, and a wireless communication port for receiving a data file, a decoder 2150 for decoding a data file such as MP3, ogg, aac, and the like; A sound output unit 2160 for outputting a data file, a condition search unit 2170 for identifying a physical and mental condition of the user on the day, and recommending the most optimized data file to the user; and a data file stored in the storage unit. Tag extraction means (2180) for extracting only the tag for updating the file information data of the tag, and tag update to classify the data file into hierarchical or directory structure based on the file information data of the tag if there is an updated tag. Means 2190 and display means 2200 for displaying the file information data of the tag upon reproduction of a data file such as an MP3 file.

The above-described system is an independent device and can be installed or integrated into a computer, a mobile phone, a portable storage device, a PDA, or a DMB phone, or can be integrated into the devices as software having these functions. Can be. When the system is applied to a computer, the display means 2200 may be a computer monitor, and when applied to a mobile storage device, a PDA, a DMB phone, a mobile phone, or the like, it may be a screen window of the device.

First, according to the present invention, based on the file information data of the tag of the data file to which tags such as MP3, ogg, aac, etc. will be described to classify or filter the data file in a hierarchical or directory structure. same. In the following description, the MP3 file will be described. However, the present invention will be described first to be applicable to all data files to which a tag having file information data such as MP3, ogg, aac, etc. is attached. Hereinafter, only MP3 files will be described by way of example.

Typically, MP3 files provided through a professional music provider such as a record label have an ID3v1 tag or ID3v2 tag, and the ID3v1 tag is accompanied by information such as track / title / artist / album name / genre / detail information, and an ID3v2 tag. Includes information such as composer / lyrics / original artist / copyright / URL / one person, you can check the information about the MP3 file in detail. However, this information is only displayed on the playback device via the display window when played back through a playback device such as an MP3 player.

In the present invention, data files such as MP3 files are automatically filtered or classified into a hierarchical structure or a directory structure (folder structure) using file information data of such a tag and stored.

First, an MP3 file is received through a communication port 2140 such as a USB port, a direct-infrared port, and a wireless communication port such as Bluetooth. At this time, if the playback device is a computer, it is also possible to convert the music file contained in the music CD into a wave-shaped music file and all compressed audio files of compressed MP3, ogg, aac.

Then, the tag filtering means 2130 checks the file information data of the tag attached to the MP3 file under the control of the central control unit 2110 and classifies by file information. That is, if the MP3 file is to be stored in the playback device for the first time, as shown in FIG. 6, the directory structure is formed for each file information of the tag so that the MP3 file is linked for each directory structure. In other words, in general, in the directory structure applied to the hard disk of a computer, files are stored for each folder, and the files in the folder do not operate in association with other folders. However, in the directory structure according to the present invention, unlike a directory structure generally used in a computer, an MP3 file is linked with an associated directory structure through file information data of the tag. That is, only one MP3 file is stored in the storage means 2120, but the tag of the MP3 file is connected to various directory structures.

For example, as shown in Figure 6, when stored in the removable storage device according to the MP3 songs of the ballad singer Shin Seung-hun's second album, it is classified by the tag filtering means (2130), Shin Seung-hun under the artist name folder It is connected to the folder and also connected to the 2nd album folder, which is a subfolder of the Shin Seunghoon folder, since it is the 2nd album of Shin Seung-hoon, and also connected to the ballad folder under the genre folder because the song is ballad and displayed through the display means 2200. Will be. Therefore, the MP3 file can be called through the ballad folder of the genre, and the MP3 file can also be called through the second album folder in the Shin Seung-hun folder of the singer folder.

In the above, the hierarchical structure or the directory structure of the folder structure may be changed to a position that the user can most easily browse, that is, an upper position according to the number of times of use by the control of the central controller 2110. .

Then, it transmits to the music recognition platform 300 through the communication port 2140, the user device 600 and the Internet. Then, the search server 310 of the music recognition platform compares the transmitted tag information with the tag stored in the music information DB 340, and if the transmitted tag has a lower version than the tag stored in the tag DB, In this case, the tag in the tag DB with the higher version is transferred to the portable storage device. Then, the tag update means 2190 of the removable storage device attaches the new version of the tag transmitted to the corresponding MP file in the storage means 2120 and at the same time hierarchically structures the MP3 file based on the file information data of the tag. Or it is classified into a directory structure. In other words, when an MP3 file whose genre is classified as classic is classified as semi-classical by a new tag, the classic is changed to semi-classical among the file information data of the tag of the MP3 file, and the connected genre folder is a semi-classical folder. Will be.

As described above, the apparatus of the present invention can always update the tag information of the MP3 file online.

Next, the music recommendation function according to the present invention will be described.

Different people have different musical tastes, so they tend to listen to only their favorite music. However, depending on the mental and physical condition of a person, the music you want to listen to may be different from your usual taste. For example, it is widely known that humans have physical and mental ups and downs by biorhythms, and in particular, Asians such as Koreans feel that their mental and physical states are changed by ideological philosophy, that is, four weeks. Inevitably, the physical and mental state of a person does not necessarily change according to the above conditions, but may exist as a mental burden depending on the person. Therefore, the present invention has the function of providing the optimum music according to the mental and physical conditions of the day according to the human rhythm or four weeks.

The music recommendation function includes a program such as a biorhythm or four weeks in advance in the condition search unit 2170 in the system 2000 according to the second embodiment of the present invention. Based on this, the music file that can be most optimized for the user is found from the storage means 2120 and provided to the user. Therefore, when it is judged that the mental and physical state of the user is not good, light ballad music or dance music is provided, and the mental and physical state is so good that some degree of restraint is necessary, especially When driving, music such as classical music or jazz music can be provided.

In the above, the condition retrieval unit 2170 having a music recommendation function is built in the portable storage device according to the present invention, but instead, the condition recognition DB 350 is formed on the music recognition platform 300, After connecting a portable storage device to the system via online, it is possible to recommend music based on user information (date of birth) at the request of the user. In this case, although recommendation music may be provided to only MP3 files stored in the storage means 2120 of the system 2000, the music optimized for the music DB 320 of the platform 300 is searched and recommended. As music, it can be provided to a playback device, that is, a user device.

In addition, although the above-described classification of the hierarchical structure or the directory structure type of the data file such as the MP3 file is performed through the tag filtering means 2130 of the mobile storage device, the tag filtering function is provided in the music recognition platform 300 instead. , The mobile storage device is connected to the system 300 through online, and the hierarchical structure or the directory structure of the MP3 files stored in the system storage unit 2120 may be classified by the tag filtering function of the system.

Since a communication means such as a mobile phone is always connected to a communication base station, a separate communication connection procedure may not be necessary. For example, in order to locate the mobile phone, the mobile phone periodically transmits a pilot signal, and the pilot base station receives the pilot signal. Therefore, the audio gene can be transmitted together with the pilot signal transmission.

When the music recognition platform 300 receives the audio gene related to the music file being reproduced from the communication means 700, the search server 310 finds the matching music through the music sampling (audio gene) DB 330. Then, the music information about the music file being played is extracted from the music information DB 340 and transmitted to the copyright settlement system 800.

The copyright settlement system 800 calculates a royalty fee based on the received music information, and transmits the result of the settlement, that is, the name of the song and the copyright fee of the reproduced music file to the communication means 700 of the user. At this time, the settlement result notification to the communication means can be notified immediately using a text message or in addition to the end-of-month communication fee.

As described above, by installing the module 710 capable of generating an audio gene in the communication means 700 having a music file reproducing function, it is possible to always calculate the exact music file copyright fee when the music file is reproduced through the communication means. As a result, the copyright holder can receive a royalty fee without any concern, and the service provider can provide a service to the user without any burden.

On the other hand, as described in the first embodiment of the present invention, the wave-type music files provided free or paid and all audio compressed files such as MP3, ogg, aac, etc., which have been compressed, do not have detailed tag information as described above. Also, when converting a music CD's music file into an MP3 file or converting live audio data into a wave-shaped music file and all compressed audio files such as compressed MP3, ogg, aac, etc., There is no tag information at all. In such a case, the user cannot see at all about the music file being played through the display window of his own communication means. Therefore, for the convenience of the user, as in the first embodiment of the present invention, the music information is extracted from the music information DB 340 and transmitted to the user's communication means 700 to tag the music file of the user without the tag information. By attaching the information, the user can check the information on the music file being played through the display window of the communication means.

In addition, as described with the second embodiment of the present invention, the tag information may be updated at all times.

As described above, using the music tag providing system and method through the online network according to the present invention, the tag is automatically attached to the music file instead of the user manually tagging the non-tagged music file. Because of this, the convenience of the user is particularly effective.
