1 is a diagram illustrating a system of a sound source information providing method according to the present invention.

The present invention for sharing the sound source reproduced by the first terminal with the second terminal or the third terminal is largely the first terminal 100 to reproduce the sound source, the server receiving the sound source information from the first terminal 100 and manages it There is a second terminal 200a and a third terminal 200b which receive various information such as sound source information from the 300 and the server 300 and synchronize the same.

Hereinafter, each component of the sound source information providing system will be briefly described.

First, the first terminal 100 may basically include various applications capable of playing a sound source such as MP3. Through this, the sound source can be reproduced, and when the sound source is reproduced, the sound source information of the sound source can be extracted in real time.

The server 300 may be divided into a presence server 300a and a media server 300b. The presence server 300a is a server that manages terminals belonging to the sound source information providing system. Therefore, by receiving the status information, such as the sound source status from each terminal can update the status information for each terminal. Such state information may include sound source information. The media server 300b is a server that can be connected to the presence server 300a. The media server 300b is a server capable of storing a sound source, and may provide a desired sound source to the terminals or the presence server 300a.

The second terminal 200a or the third terminal 200b is connected to the server 200. The second terminal 200a and the third terminal 200b may transmit and receive various information with the presence server 300a. In addition, the second terminal 200a or the third terminal 200b may be synchronized with the control of the presence server 300a with respect to a specific state. In the present invention, since the presence server 300a receives and manages sound source information from the first terminal 100, the second terminal 200a or the third terminal 200b is a sound source of the first terminal 100. It can be synchronized with the information.

Meanwhile, when the presence server is described in more detail, the presence server may inform the status of other terminals in real time, and inform the other terminals of the presence status of one terminal. to provide.

It is developed based on the presence server Presence & Group Reference Model to enable group-like presence inquiry, and the latest standards of filtering, rate control, and partial presence can be applied for service optimization.

The presence server registers / maintains the current location of the user who is online and informs the users of this information to enable instant communication services. For example, if a watcher requests to be informed about the availability of another user's online connection, the presence system may notify the user of the availability of the online connection whenever there is a change.

2 is a diagram illustrating an example of a sound source information providing system using a presence server according to the present invention.

In connection with the present invention, a method of providing sound source information includes a method of using a media server and a method of using only a presence server without using a media server. First, with reference to FIG. 2, the latter will be described, and with reference to FIG. 3, the former will be described.

The first terminal 100 may play a sound source through a sound source playing application such as an OEM player or a specific media player (S210).

Thereafter, the first terminal 100 may extract sound source information reproduced through the sound source reproduction application (S220). Here, although sound source information extraction is shown as a step performed after sound source reproduction, it is preferable that sound source information extraction is performed simultaneously with sound source information reproduction. That is, the sound source information extraction may be extracted in real time when the sound source information is reproduced, the extracted sound source information may be stored. Here, the extracted sound source information may include various information such as song information, album name, singer, file name, image information, image information, playback time, current playback information, and the like for the sound source.

When the first terminal 100 extracts the sound source information reproduced by itself, the first terminal 100 transmits the sound source information to the presence server 300a (S230). Such sound source information transmission may be transmitted periodically or aperiodically. For example, the sound source information may be periodically extracted every 1 second, and the sound source information may be transmitted to the presence server 300a. Alternatively, the transmission may be aperiodically. When a specific event occurs, such as when the sound source reproduced by the first terminal is changed, the sound source information may be transmitted.

The presence server 300a updates the sound source state for the first terminal 100 using the sound source information transmitted from the first terminal 100 (S240). The presence server 300a may receive and manage state information about not only the first terminal 100 but also a plurality of terminals. In detail, the presence server 300a may manage a sound source state of the first terminal 100, and if the received sound source information is different from the existing sound source state, it may be updated.

The presence server 300a transmits the updated sound source information to the second terminal 200 (S250). The presence server 300a manages the presence of the connected terminals as described above, and may inform other terminals when a state of a specific terminal is changed as part of the management. In relation to the present invention, the presence server 300a receives and manages the sound source information of the first terminal 100, and transmits the sound source information of the terminal 100 to the second terminal 200.

The second terminal 200 may check the sound source state of the first terminal 100 through the sound source information from the presence server 300a (S260). Through this, the second terminal 200 confirms the sound source state of the other terminal through the presence server 300a, and downloads the sound source of the other terminal, that is, the first terminal 100 or the same sound source previously stored, as necessary. Can be reproduced and synchronized with the sound source state of the first terminal 100.

3 is a diagram illustrating another example of a sound source synchronization method using a presence server according to the present invention.

As another example of a sound source synchronization method using the presence server 300a, the media server 300b may be used. The media server 300b may store a plurality of sound source information. In addition, the media server 300b may be connected to another network, and may receive a plurality of sound sources through another network.

Hereinafter, a sound source synchronization method using the media server 300b will be described. Here, the steps overlapping with the steps described in FIG. 2 will be briefly described.

The first terminal 100 can reproduce the sound source through the sound source reproduction application (S310). The first terminal 100 may extract sound source information reproduced through the sound source reproduction application (S320). When the first terminal 100 extracts the sound source information reproduced by itself, the first terminal 100 transmits the sound source information to the presence server 300a (S330).

When the presence server 300a receives the sound source information of the first terminal, the presence server 300a updates the sound source state for the first terminal (S340).

Here, the presence server 300a synchronizes the sound source information with the media server 300b (S350). If the presence server 300a plays a role of checking and updating the state of the terminals, the media server 300b plays a role of storing and managing various sound sources, and the presence server 300a is configured as a first terminal ( The sound source information of 100 may be checked and shared with the media server 300b. Therefore, if necessary, the media server 300b may provide the presence server 300a with the same sound source as that of the first terminal 100.

The presence server 300a transmits sound source information of the first terminal 100 to the second terminal 200 (S360). Through the transmission process of the sound source information, the second terminal 200 may check the sound source information of the first terminal 100.

After confirming the sound source information of the first terminal, the second terminal 200 requests a sound source from the media server 300b (S370), and downloads the sound source therefrom (S380). That is, the second terminal 200 may reproduce the same sound source using the sound source information of the first terminal. Here, as seen above, the sound source information which can distinguish the sound source, the album name, the singer, etc. from the presence server 300a is received, and the sound source itself can be downloaded from the media server 300b. .

Meanwhile, as an additional step, the presence server 300a of the present system may recommend a sound source to the first terminal 100 or the second terminal 200 (S390). The presence server 300a manages a sound source state of each terminal, and accordingly, may recommend a sound source suitable for each terminal.

Through this process, not only the first terminal 100 that reproduces the sound source but also the second terminal 200 may be synchronized with the same sound source that the first terminal reproduces.

4 is a block diagram of a mobile terminal according to an embodiment of the present invention.

The mobile terminal 100 may play a role of playing a sound source, extracting sound source information, and transmitting the sound source information. For this operation, the mobile terminal 100 may include components having various functions.

The wireless Internet module 113 is a module for wireless Internet access, and may be built in or externally attached to the mobile terminal 100. Wireless Internet technologies may include Wireless LAN (Wi-Fi), Wireless Broadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), and the like. The short range communication module 114 refers to a module for short range communication. The position information module 115 is a module for obtaining the position of the mobile terminal, and a representative example thereof is a Global Position System (GPS) module.

Referring to FIG. 4, an A / V (Audio / Video) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes image frames such as still images or moving images obtained by the image sensor in the video call mode or the photographing mode. The processed image frame can be displayed on the display unit 151. [

The output unit 150 is for generating an output relating to visual, auditory or tactile sense and includes a display unit 151, an acoustic output module 152, an alarm unit 153, a haptic module 154, 155, and the like.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the photographed and / or received video or UI and GUI are displayed.

The control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [ The controller 180 can drive various applications related to sound source reproduction. In addition, the controller 180 may extract various information about the sound source when the sound source is reproduced by driving the sound source reproduction application. Various methods may exist in relation to sound source information extraction, and the present disclosure may describe an ID3 tag analysis method and a spectrum analysis method in connection with FIGS. 5A and 5B.

The controller 180 may control an operation related to sound source reproduction and an operation related to sound source extraction, and control the terminal using information related to each operation.

The power supply unit 190 receives an external power source and an internal power source under the control of the controller 180 to supply power for operation of each component.

5A and 5B are diagrams for explaining sound source information extraction operations in connection with the present invention.

In connection with the present invention, the controller 180 of the mobile terminal 100 can extract sound source information for the sound source being played. Although various methods may exist as a method of extracting sound source information, a method of analyzing an ID3 tag and a method of analyzing a spectrum of a sound source will be described with reference to FIGS. 5A and 5B.

First, referring to FIG. 5A, an ID3 tag of audio data is illustrated as a sound source.

First, the ID3 tag refers to a format used as a standard for adding information such as a song name, author, music channel, etc. to an MP3 file.

In general, MP3 represents a compression standard called Moving Picture Experts Group (MPEG) Audio Layer-3, and an MP3 sound source is a digital file composed of music compressed with MP3. The MP3 music file is a new music format that has gained great popularity recently among PC users as the sound quality is reproduced almost similar to that of an audio CD, and the size of the file is only about one-tenth the size of an audio CD. Thanks to this innovative development of digital audio data processing technology, a portable digital audio player, or MP3 player, has emerged. In addition, a memory card can be used to output a desired audio for a long time without degrading sound quality without a tape or CD.

Referring to FIG. 5A, in the audio data such as the MP3 file, important information of ID3, that is, information on a corresponding song, is recorded in a tag portion located at the rear end. Here, the ID3 tag stores information such as title, artist, album name, year, year, music genre, comment, and the like. It is created at the time of production and contains a lot of unused space in addition to the area where basic information about the song in MP3 is recorded.

Each information of the ID3 tag has a specific position and length, and the sound source information for the MP3 can be grasped through specific information included in each position or length.

When a sound source such as MP3 starts to be reproduced by the control of the controller 180, the controller 180 may analyze an ID3 tag for the sound source. Therefore, accurate information about the sound source such as music title, artist, album name, song year, music genre, and comment on the sound source can be analyzed and extracted.

The extracted sound source information may be stored in the memory 160 of the mobile terminal 100 or may be directly transmitted to the presence server 300a through the wireless communication unit 110.

Next, referring to FIG. 5B, when it is difficult to extract sound source information through the ID3 tag, the spectrum of the sound source file may be analyzed.

Since a sound source such as MP3 has a sound, it has a constant amplitude and frequency, and as the sound source is reproduced, it can form a spectrum unique to the sound source. 5B is a diagram illustrating a spectrum of a sound source when the sound source is reproduced. That is, as time passes, various spectra may be formed according to the amplitude and frequency of the sound source.

Here, the controller 180 can analyze the spectrum inherent in such a sound source, and can identify a sound source having the spectrum. In detail, the controller 180 may check the spectrum of the sound source through various paths. For example, the spectrum of various sound sources may be stored in the memory 160, and the spectrum of the sound source may be grasped from the outside through the wireless communication unit 110. That is, when the controller 180 confirms the spectrum of the reproduced sound source, the spectrum of the existing sound source is searched through the memory 160 or the wireless communication unit 110 to compare the spectrum of the reproduced sound source with the existing sound source, In case of a match, the sound source to be played may be determined as the existing sound source. If it matches, the controller 180 may determine the information about the existing sound source as the information about the sound source reproduced in the terminal 100, store it or transmit it to the presence server 300a.

6A and 6B illustrate a sound source synchronization method using an address book in connection with the present invention.

In the present invention, the user can check the sound source synchronization process through the address book. The presence server 300a may manage a plurality of user terminals, and may synchronize sound source information in connection with the present invention. Here, each of the plurality of user terminals may check such a synchronization process through an address book. For example, the address book may provide information on each terminal constituting one network through the presence server 300a.

For example, referring to FIG. 6A (a), the terminal A address book 600a is displayed. Here, the A terminal address book 600a may display information 610 about itself. In addition, the terminal A address book 600a is the information of the other terminals connected through the presence server 300a as information of the terminal B 612, the information C terminal 614, the information D terminal 616, and the terminal E E. Information 618 may be included. Information about other terminals in the address book may be updated in real time or periodically through the presence server 300a. In addition, the information on the other terminals may include a variety of information such as a picture of the user of the other terminal, the phone number of the other terminal, whether the other terminal is logged in, the sound source information of the other terminal.

The address book may be displayed through the display unit or the touch screen 151 of each terminal. Therefore, the controller 180 of the terminal can transmit and receive information of the other terminal from the presence server 300a in real time or periodically to update and display the information of each terminal through the address book.

Referring to FIG. 6A, when the terminal 100 starts to play a sound source from the standpoint of the terminal 100 playing the sound source, sound source information of the sound source to be played through the address book is displayed.

If (a) of FIG. 6A is to display an address book before playing a sound source, FIG. 6A (b) is a diagram showing an address book after playing a sound source.

In FIG. 6A (b), when the terminal 100 starts to play a sound source, the controller 180 extracts information on the sound source to be played as described above. Thereafter, the controller 180 can display information on the corresponding sound source through the address book. The address book 600a may display the sound source information 622 reproduced through the window 610 indicating information of the terminal 100 itself.

6B is a diagram illustrating an operation of checking and synchronizing sound source information of a counterpart terminal through an address book.

Referring to FIG. 6B (a), the address book 600b of the terminal B is displayed. Similar to the address book 600a of the terminal A, the address book 600b of the terminal B can be displayed on the display of the terminal B, through which the user of the terminal B can check the status of the other terminals.
