3A is a conceptual diagram illustrating a communication network to which a mobile terminal and a server are connected according to an embodiment of the present invention. The communication network to which the mobile terminal and the server are connected is composed of an electronic device and an IP (Internet Protocol) server.

Referring to FIG. 3A, the electronic device may include all electronic devices capable of wireless communication such as a mobile terminal, a laptop, and a television.

The electronic device can transmit data to the RNC control station through the Node B base station. An RNC (Radio Network Controller) control station is also called a radio network control station. The RNC control station can perform functions for radio resource management of the asynchronous mobile communication system, management of the base station in the wireless subscriber network, and management of interfaces between the radio network controller and other network elements.

The data transmitted to the RNC control station may be transmitted to the IP server via the network. Networks can be classified as packet networks and circuit networks.

That is, when the wireless communication is connected from the electronic device to the IP server, the data is divided into packet units, and when the packet is transmitted to the IP server through a different path for each packet, the data is transmitted to the IP server through the packet network. In this case, when data is transmitted, the data path can be shared with other packets.

On the other hand, when wireless communication is connected from the electronic device to the IP server, data is transmitted to the IP server through the circuit network when the data is transmitted to the IP server through the same path from the start to the release of the wireless communication. In this case, a predetermined data path can be used exclusively for data transmission.

In more detail, the packet network may include an SGSN and a GGSN.

SGSN refers to a node that is responsible for delivering data packets to and from a mobile station within a service area. The SGSN can perform packet routing and transmission functions. The location register of the SGSN may store location information of a General Packet Radio Service (GPRS) user registered in the SGSN, a user profile (e.g., International Mobile Station Identification Number (IMSI)), and the like.

Next, the Gateway GPRS Support Node (GGSN) is also referred to as a packet gateway support node. The GGSN means a node responsible for the connection function between the GPRS backbone network and the external packet data network. The GGSN converts the GPRS packet received from the SGSN into an appropriate Packet Data Protocol (PDP) format and transmits it to the IP server and converts the PDP address of the incoming packet data to the recipient's global mobile communication system (GSM) address Can be performed.

FIG. 8A is a conceptual diagram illustrating a control method of FIG.

Meanwhile, in the following embodiments, an electronic device will be described as an example of a mobile terminal, and the mobile terminal may include at least one of the components discussed above with reference to FIGS. 1, 2A, and 2B.

4, a mobile terminal 100a, a target device 100b, and a server 200 according to an embodiment of the present invention will be described as an example. 4, the first terminal 100a and the target device 100b are connected to the server 200 via the network, and the first terminal 100a shares the selected sound source data with the target device 100b It is possible to simultaneously reproduce the stream.

Here, the target device 100b includes all the electronic devices having the same or similar components as those of the mobile terminal 100a. The target device 100b is connected to the server 200 and communicates with the mobile terminal 100a It is possible. Herein, connecting to the server 200 via the network includes connecting to the server 200 by executing the downloaded application on the first terminal 100a and the target device 100b. Here, the 'sharing of the selected sound source data' means that the sound source data selected from the memory (not shown) associated with the memory 160, the server 200, or the server 200 of the mobile terminal 100a Is provided to the target device 100b through the server 200 by the first terminal 100a connected to the server 200. [

In addition, 'stream reproduction' means that the selected sound source data is transmitted in the form of streaming from the server 200 to be reproduced in the first terminal 100a and the target device 100b connected to the server 200, Streaming the sound source data pre-stored in the server 100a to the target device 100b connected to the server 200 via the server 200 and playing back the sound source data. Further, the 'sound source data' disclosed in this specification is a concept including the lyric data and the lyric data corresponding to the sound source data unless otherwise stated.

In addition, the 'server' disclosed herein can store and provide at least one sound source data, and can calculate score data, for example, a song score and a rank, based on an acoustic signal received from the outside, It is possible to provide synchronized lyrics data and lyrics synchronization data corresponding to the lyrics data.

The wireless communication unit 110 according to an embodiment of the present invention accesses the server 200 through a network and receives sound source data capable of stream reproduction from a memory associated with the server 200 or the server 200. [

In order to share sound source data with the target device 100b connected to the server 200, the controller 180 first transmits a sound source data sharing request message to the server 200 And causes the server 200 to transmit a sharing request message to the target device 100b.

When the response message of the target device 100b is received from the server 200 in response to the transmission of the sharing request message, the control unit 180 transmits the sound source data to the main body of the mobile terminal 100a, And controls the wireless communication unit 110 to simultaneously reproduce streams from the device 100b. At this time, the target device 100b may be specified by the mobile terminal 100a, and the identification information of the target device 100b for specifying the target device 100b may be stored in the memory 160 of the mobile terminal 100a, Stored information.

Hereinafter, a method for controlling the mobile terminal 100a to share sound source data with the target device 100b and to simultaneously reproduce the sound source data will be described in more detail.

First, the mobile terminal 100a selects sound source data to be shared (S410). The sound source data is stored in the memory 160 of the main body, the server 200 connected to the mobile terminal 100a via the network, and the memory (not shown) interlocked with the server 200, . For example, the mobile terminal 100a can select at least one sound source data by sequentially or simultaneously requesting the server 200 to transmit specific sound source data (including corresponding lyric data, household synchronization data) . In addition, the selection of the sound source data may be selected from one of the sound source data lists created by connecting to the sound source providing server (not shown) other than the server 200, for example.

On the other hand, if the connection to the server 200 is performed by executing the application downloaded to the mobile terminal 100a, an object corresponding to the sound source data displayed in the screen information of the executed application is selected and the at least one sound source data .

When the sound source data is selected as described above, the mobile terminal 100a selects a target device to share sound source data (S420). The selectable target diabe may be plural. Also, the selection of the target device may be performed by selecting identification information of any one of the target devices in the friend list (or 'list of recipients') stored in the memory 160 of the mobile terminal 100a, And selecting a target device.

Here, the friend list means a list of target devices in which identification information is stored in at least one of the mobile terminal 100a and the server 200 so that sound source data can be shared. For example, And may correspond to stored address book information.

In this case, the identification information may be a unified resource identifier (URI), for example, at least one of a Tell URI and a SIP URI. As described above, in the mobile terminal 100a, The control unit 180 can transmit the identification information of the selected target device 100b to the server 200. [

When the target device to share sound source data is selected, the wireless communication unit 110 of the mobile terminal 100a transmits the selected sound source data sharing request message to the server 200, and transmits the shared sound request message to the target device 100b (S430). As described above, the sharing request message may include the identification information of the mobile terminal 100a that generated the sharing request message. For this, a control key may be displayed and activated on the display unit 151 of the mobile terminal 100a, in which text information such as 'invite', 'share', etc. is displayed.

In response to the sharing request message being transmitted, the server 200 receives a response message from the target device 100b (S440). Through a pop-up window displayed on the display unit of the target device of the creation of the response message. The response message includes 'accept' or 'reject' for the shared request message, and can be implemented as 'rejected' if the response message is not received within a predetermined time. To this end, a pop-up window may be displayed on the display unit of the target device 100b to selectively generate a response message for the sharing request message.

When the 'Accept' response message is received from the server 200, the control unit 180 of the mobile terminal 100a transmits the sound source data to the main body of the mobile terminal 100a and the target device 100b simultaneously And controls the wireless communication unit 110 to reproduce the stream.

That is, when a control signal for instructing stream reproduction of sound source data is input through the user input unit 130, the control unit 180 reproduces the sound source data through the sound output module 152, 100b so that the sound source data is simultaneously reproduced.

At this time, if stream reproduction is stopped in the mobile terminal 100a or the target device 100b during the stream reproduction, the control unit 180 of the mobile terminal 100a stores the previous playback position in the memory 160, It is possible to reproduce the stream from the stored playback position in accordance with the control signal.

Meanwhile, in another embodiment, when the target device is close to the mobile terminal 100a, the wireless communication unit 110 of the mobile terminal 100a may transmit the selected sound source data directly to the target device using the short- have.

When the sound source data is simultaneously reproduced in the mobile terminal 100a and the target device 100b, the sound output module 152 outputs the sound signal input through the microphone 122 along the sound source data reproduced from the stream, For example, the voice of the user or the sound of the instrument is output together with the sound source data. That is, the users of the mobile terminal 100a and the target device 100b can perform singing together with the sound source data to be output.

At this time, the mobile terminal 100a and the target device 100b can output the lyric data corresponding to the sound source data while displaying the current reproduction position by synchronizing with the stream reproduction.

8A, a display unit 151 of a plurality of mobile terminals 100a, 100b, and 100c connected to the server 200 may be provided with lyric data synchronized with sound source data reproduced from streams, for example, For example, 'Gangnam style Gangnam style' is displayed together. Here, the lyric data corresponding to the sound source data reproduced up to the present time is 'Okan Gangnamsu', and it can be understood that the current playback position is 's' to be changed in a thick shape next time. At this time, when stream reproduction is stopped in the mobile terminal 100a that requested the sound source data sharing to the mobile terminals 100b and 100c, the streaming is simultaneously stopped in the mobile terminals 100b and 100c corresponding to the target device . When stream reproduction is restarted in the mobile terminal 100a, it is possible to perform stream reproduction again in the other mobile terminals 100b and 100c depending on the restart of the stream.

8A, when the song reproduction is completed, that is, when stream reproduction of the sound source data is completed, the wireless communication unit 110 transmits the sound source data and the sound signal output through the sound output module 152 to the server (200). The server 200 calculates score data corresponding to the transmitted sound source data and the sound signal and transmits the score data to the wireless communication unit 110. The display unit 151 transmits the received score data to the mobile terminals 100a, 100b, 100c ). Here, the score data may further include ranking information for the mobile terminals 100a, 100b, and 100c. In addition, the score data can be updated and displayed every time stream reproduction of sound source data is completed.

As described above, embodiments of the present invention can share a selected sound source with a target device connected to a server, and simultaneously reproduce the sound source data in a target device responding to a sharing request when reproducing sound source data, It is possible to implement a function of simultaneously singing in a plurality of spaced apart mobile terminals.

In this regard, reference numeral 5 is a flowchart for explaining operation modes that are different depending on whether or not selected sound source data are shared according to an embodiment of the present invention.

Referring to FIG. 5, the mobile terminal 100a accesses the server 200 through a network and selects sound source data capable of stream reproduction (S510). The sound source data is stored in the memory 160 of the main body, the server 200 connected to the mobile terminal 100a via the network, and the memory (not shown) interlocked with the server 200, .

When the sound source data is selected, the user input unit 130 of the mobile terminal 100a selects one of the first operation mode and the second operation mode, which is selected according to whether the selected sound source data is shared with other external electronic devices Control command is input. Accordingly, the control unit 180 determines whether the selected sound source data is in a shared mode (S520).

If the first operation mode is selected, that is, the mode is not the sound source data sharing mode, the controller 180 streams the selected sound source data only in the mobile terminal 100a based on the first input signal (S530). A user of the mobile terminal 100a can perform song singing along with sound source data that is played back by itself or multiple streams.

If the second operation mode is selected, that is, in the sound source data sharing mode, the control unit 180 controls the selected sound source data to be reproduced simultaneously on the target device as well as on the mobile terminal 100a based on the second input signal do.

More specifically, when the second operation mode is selected, the control unit 180 first selects a target device to share sound source data (S540). If the target device is selected, the server 200 transmits a sharing request message to the target device via the server 200, and receives a response of the target device from the server 200 (S560). The controller 180 controls the selected sound source data to be simultaneously played back in the main body of the mobile terminal 100a and the target device according to a predetermined control signal in operation S560. Then, the user of the mobile terminal 100a and the user of the target device can perform singing together along with the sound source data stream-reproduced using their own terminals.

When the stream reproduction in steps S530 and S560 is completed, the score data received from the server is received on the display unit of the mobile terminal and / or the target device (S570).

Specifically, in the first mode, only the score data corresponding to the sound source data and the sound signal output from the mobile terminal 100a are displayed on the display unit 151, and in the second mode, the mobile terminal 100a and the target device output And score data corresponding to the sound signal are displayed on the display unit 151, respectively.

As described above, it is possible to selectively perform song singing by causing the user to stream music data to only his / her mobile terminal, or to perform streaming simultaneously on his / her mobile terminal and target device, Thereby satisfying various user's preferences and providing convenience.

Hereinafter, a control method capable of singing together in one mobile terminal even when the sound source data is set to be reproduced only by the own mobile terminal will be described. In this regard, FIG. 6 is a flowchart illustrating a control method for performing singing by a plurality of people according to sound source data reproduced by a single mobile terminal, according to an embodiment of the present invention.

Referring to FIG. 6, when sound source data capable of stream reproduction is selected by the mobile terminal 100a, the selected sound source data is stream-reproduced in the mobile terminal 100a according to a predetermined input signal.

The sound output module 152 of the mobile terminal 100a outputs the sound signal input by the user together with the sound source data reproduced from the stream, for example, a user voice, an instrument sound, or the like (S610).

At this time, a plurality of voice characteristics may be included in the outputted acoustic signal. That is, when a sound signal inputted along the sound source data reproduced by the stream is a voice input by a plurality of users at the same time, the output sound signal includes a plurality of sound characteristics.

The control unit 180 of the mobile terminal 100a determines whether a plurality of voice characteristics are included in the output sound signal (S620)

As a result of the determination, if the sound signal is a sound signal input by a single user, the sound signal is directly transmitted to the server 200, and the server 200 calculates score data based on the transmitted sound signal. Then, the mobile terminal 100a receives the score data corresponding to the sound signal from the server 200 and displays it on the display unit 151. FIG.

On the other hand, if it is determined in step S620 that the sound signal is a sound signal input by a plurality of users, that is, if the outputted sound signal includes a plurality of sound characteristics, And provides the extracted voice characteristic information to the server 200 (S640).

For example, when the output sound signal includes the sounds of the user 1, the user 2, and the user 3, the control unit 180 outputs the sound signal 1 input by the user 1 according to the respective sound characteristics, And transmits the extracted voice characteristic information, i.e., the user information and the corresponding sound signal to the server 200. The server 200 transmits the extracted voice characteristic information to the server 200, The server 200 calculates score data corresponding to each transmitted voice characteristic and transmits the score data to the mobile terminal 100a. The mobile terminal 100a transmits the received score data to the display unit 151 ). At this time, the user information corresponding to the extracted voice characteristic information can be stored in advance before the sound source data is reproduced as a stream.

As described above, since the selected sound source data is stream-reproduced only by one mobile terminal, a plurality of users can perform singing together so that a pleasure called together and a realistic environment such as a real karaoke can be provided have.

Hereinafter, with reference to FIG. 1, FIG. 4, FIG. 7, and FIG. 8B, a control method for sharing a recording file created while singing songs along stream source data to be played back to other users will be described. In this regard, FIG. 7 is a flowchart illustrating a control method for sharing a recording file generated according to sound source data reproduced by a stream with other electronic devices, according to an embodiment of the present invention.

7, when sound source data capable of stream reproduction is selected by the mobile terminal 100a, the selected sound source data is transmitted from the mobile terminal 100a or from the mobile terminal 100a and the target device in accordance with a predetermined input signal. The stream is simultaneously reproduced.

Accordingly, the sound output module 152 of the mobile terminal 100a transmits the sound signal input by the user of the mobile terminal 100a or the mobile terminal 100a and the target device together with the sound source data reproduced from the stream, for example, Voice, instrument sound, etc. (S610).

As stream reproduction of the sound source data proceeds, the controller 180 records sound source data and sound signals output through the sound output module 152 and generates a recording file for the sound source data (S720). To this end, as streaming of the sound source data is started, a 'recording function key' for recording is displayed on the display unit of the mobile terminal 100a or the mobile terminal 100a and the target device, Quot ;, the recording function can be activated based on the user's gesture with " key ".

When the recording file is generated, the control unit 180 provides the generated recording file to the mobile terminal and the target device connected to the server 200 based on a predetermined control signal (S730). In another embodiment, when a predetermined control signal is input, the control unit 180 may upload a recording file created in the SNS (e.g., Kakao Talk, Facebook) linked with the server 200. [

When the recording file is generated as described above, the control unit 180 controls the display unit of the mobile terminal 100a or the mobile terminal 100a and the target device in accordance with the predetermined control signal, Output.

Referring to FIG. 8B, when the screen information related to stream reproduction of the selected sound source data is output to the mobile terminal 100a, the user performs a song function in accordance with the stream playback while watching the displayed screen information, Can be performed. An indicator 810 indicating that recording is being performed is displayed on the display unit 151 of the mobile terminal 100a. When the song is completed, the controller 180 detects the touch applied to the 'recording completed key' 820 for performing the recording completion as shown in FIG. 8B, and performs recording completion. When the control signal is inputted through the 'recording completion key' 820, the generated recording file is transmitted to the target device 100b connected to the mobile terminal 100a and the server 200, And outputs the image object 840 corresponding to the created recording file to the controller 151. [

Referring to FIG. 7 again, the control unit 180 may perform a playback / editing function for a recorded file provided according to a touch input applied to the output image object (S750).

Specifically, when a first touch input is applied to an output image object, a playback function for the provided recording file is performed, and when a second touch input is applied to the output image object, an editing function for the provided recording file is performed, You can create a recording file. The generated second recording file is provided to the mobile terminal body and the target device connected to the server according to the second control signal.

On the other hand, if the edit function for the recorded file is performed to generate the second recorded file (S760), the steps described above (S730 to S760) can be repeatedly performed.

8B, an image object 840 corresponding to a recording file is displayed on a display unit 151 of the target device 100b provided with a recording file in FIG. 8B, and an image object 840 corresponding to a recording file Information 845, e.g., the title of the sound source data, the playback time, etc., can be displayed.

At this time, if the touch input of the user is applied to the image object 840, a popup window 850 for performing a predetermined function on the recorded file corresponding to the image object 840 may be output. In this pop-up window 850, preview information of a recording file corresponding to an image object, for example, a thumbnail, may be output, and a predetermined function key , For example, a function key showing the text of 'play' and 'edit' may be displayed.

When the 'play' key is selected in the pop-up window 850, the recording file is reproduced and outputted through the sound output module 152. If the 'edit' key is selected in the pop-up window 850, the control unit 180 may record the other sound signal input through the microphone 122 while being covered with the recording file while the recorded file is being played back.
