The communication unit 71 provides an interface for connecting the server device S to each karaoke device and each mobile terminal. The control unit 72 performs various controls in the server device S. As shown in FIG. 4, the control unit 72 according to the present embodiment functions as a first specifying unit 72a, a generating unit 72b, an instructing unit 72c, a second specifying unit 72d, and a transfer unit 72e.

[First Specific Part]
The 1st specific part 72a specifies the one karaoke store where the said user is staying based on the user position information which shows the whereabouts of the said user acquired with the portable terminal which a user owns. ..

For example, it is assumed that the user U1 activates the karaoke application on the mobile terminal M1 after entering the room R1 of the karaoke store L1. In this case, the position acquisition unit 15a of the mobile terminal M1 uses GPS to acquire the user position information of the user U1. The transmission/reception processing unit 15c transmits the user position information to the server device S.

The first identifying unit 72a converts the received user position information into address data. A known method can be used as a method of converting the user position information into an address. The 1st specific part 72a collates the converted address data with the address list memorize|stored in the memory|storage part 70, and it is one karaoke store from the some karaoke stores included in an address list (in the above example, karaoke store. The store L1) is specified.

[Generator]
The generation unit 72b sequentially identifies the music pieces that are being karaoke based on the karaoke performance sound collected by the mobile terminal, and generates a performance list.

In the above example, the user U1 who has entered the room R1 of the karaoke store L1 sings karaoke while the karaoke application is activated on the mobile terminal M1. In this case, the sound collection processing unit 15b of the mobile terminal M1 controls the sound collection unit 14 to collect the karaoke performance sound. The transmission/reception processing unit 15c transmits the collected karaoke performance sound to the server device S.

When the karaoke performance sound is received, the generation unit 72b analyzes the karaoke performance sound and identifies the music piece being karaoke performance. A well-known method can be used as a method of identifying the music piece during karaoke performance. For example, the generation unit 72b converts the karaoke performance sound into musical note information, divides the musical composition converted into musical note information into a plurality of music pieces, and generates music pieces, and among the musical piece data stored in the storage unit 70, the music. A music piece including a piece is specified (for details, the description of Japanese Patent Laid-Open No. 2000-172693 is incorporated).

Generally, the music that can be performed by each karaoke device is a music distributed from the server device S. Therefore, the generation unit 72b can identify one song by analyzing the karaoke performance sound.

The generation unit 72b sequentially specifies the music pieces that are being karaoke played each time the karaoke performance sound is transmitted. Then, the generation unit 72b generates a performance list in which the identified music pieces are arranged in time series. The play list shows the music pieces that have been karaoke-played while the user is using one karaoke device.

FIG. 6 shows an example of a performance list of music pieces in which the user U1 and the user U2 have performed karaoke singing using the karaoke device K1 shown in FIG. In this performance list, the music IDs and music names of the musics that have been karaoke-played are recorded in time series based on the time information.

[Instruction part]
When the first specifying unit 72a cannot specify the one karaoke shop after the one karaoke shop is specified, the instruction unit 72c causes the plurality of karaoke devices installed in the one karaoke shop to be specified. On the other hand, it instructs to transmit the song history stored after the performance time indicated by the time information of the karaoke song of the first song included in the performance list.

The first specifying unit 72a specifies a karaoke shop each time the user position information is received from the mobile terminal.

Here, in the above example, it is assumed that the users U1 and U2 who have used the karaoke device K1 finish the singing of karaoke songs and leave the karaoke store L1. With the exit of the user U1, the position information acquired by the position acquisition unit 15a of the mobile terminal M1 is different from the position information of the karaoke store L1. In this case, the transmission/reception processing unit 15c transmits the newly acquired user position information (information indicating a position other than the karaoke shop L1) to the server device S.

Since the user U1 has left the karaoke store L1, there is no karaoke store corresponding to the newly acquired user position information. Therefore, the first specifying unit 72a cannot specify the karaoke shop. In this case, the first specifying unit 72a outputs a signal to that effect to the instruction unit 72c.

The instruction unit 72c, for the karaoke apparatus K1 to the karaoke apparatus K1 installed in the karaoke shop L1 in which the user U1 was staying, is the first song included in the performance list among the song histories stored in each karaoke apparatus. The singing history stored after the performance time indicated by the karaoke singing time information of the song is transmitted.

For example, the instruction unit 72c transmits the time information of the first music piece included in the performance list.

Each karaoke device reads the corresponding song history from the song history stored in the storage unit 23 based on the instruction from the instruction unit 72c, and transmits the song history to the server device S.

[Second specific part]
The second specifying unit 72d specifies one song history that matches the performance list from the received plurality of song histories.

The second specifying unit 72d sequentially compares the music IDs of the music pieces included in the received plurality of song histories with the music IDs of the music pieces included in the play list, so that the same music piece as the music piece included in the play list is obtained. , The singing history of karaoke performed in the same order is specified. That is, the coincidence between the performance list and the singing history is determined by the information (song ID, song name, etc.) for identifying the song played by karaoke and the order of karaoke performance.

In the above example, the user U1 and the user U2 are singing karaoke songs using the karaoke device K1. In this case, the song history transmitted from the karaoke device K1 matches the performance list.

Note that generally, a karaoke device in a karaoke store is used by a plurality of users or groups one after another. Therefore, in the above example, another group may sing a karaoke song immediately after the user U1 or the like leaves the store. In that case, the storage unit 23 stores the singing history after the user U1 or the like has left the store. Therefore, the singing history received from the karaoke device may include the singing history other than the user U1 and the like.

In such a case, the second identifying unit 72d extracts only the history that matches the performance list from the received song history and identifies it as one song history. FIG. 7 shows an example of a song history that matches the performance list of FIG.

[Transfer section]
The transfer unit 72e transfers the specified one song history to the mobile terminal of the user. The mobile terminal to be transferred can be specified by the terminal ID received from the mobile terminal together with the user position information.

The mobile terminal that has received one song history can display the new song history on the display via the karaoke application. Therefore, the user can browse his/her own singing history on his/her mobile terminal. When one karaoke device is used by a plurality of people, the singing histories of all the users are transferred to the mobile terminals of the respective users who have activated the karaoke application. Even in this case, each user can identify and browse his or her singing history from the song name or the like. Further, in the example of FIG. 1, when the user U1 and the user U2 leave the store at the same time, the karaoke system 1 executes the same process as above according to an instruction from the mobile terminal M2, and the mobile terminal M2 receives the mobile terminal M1. Send the same song history. Therefore, the user U2 can browse the same singing history as the user U1 on his own mobile terminal.

==About processing in the karaoke system==
Next, a specific example of processing in the karaoke system 1 according to the present embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing a processing example in the karaoke system 1. In this example, it is assumed that the user U1 activates the karaoke application on the mobile terminal M1 after entering the room R1 of the karaoke store L1. Further, the position acquisition unit 15a of the mobile terminal M1 acquires user position information indicating the whereabouts of the user U1, and the transmission/reception processing unit 15c transmits the acquired user position information to the server device S together with the terminal ID. Suppose

The first specifying unit 72a specifies the karaoke shop L1 in which the user U1 is staying, based on the user position information acquired by the mobile terminal M (specification of karaoke shop, step 10).

The user U1 starts karaoke singing by using the karaoke device K1 in the room R1. The history processing unit 21b of the karaoke device K1 accompanies the karaoke singing of the user U1, and music identification information of the karaoke-played music, time information including the performance time at which the karaoke singing is performed, and the karaoke singing accompanying the karaoke performance. The song history including the scoring result evaluated is stored (memorization of song history, step 11).

When the user U1 is singing a karaoke song, the sound collection processing unit 15b of the mobile terminal M1 controls the sound collection unit 14 to collect the karaoke performance sound of the user U1. The transmission/reception processing unit 15c transmits the collected karaoke performance sound to the server device S.

The generation unit 72b sequentially identifies the music pieces that are being karaoke-played based on the karaoke performance sounds that are collected by the mobile terminal M1, and displays a performance list of the music pieces that were karaoke-played by the user U1 while using the karaoke device K1. Generate (generation of performance list, step 12).

After that, it is assumed that the user U1 finishes singing the karaoke song and leaves the karaoke store L1. In this case, the first specifying unit 72a cannot specify the karaoke store where the user U1 is staying.

When the karaoke store cannot be specified (Y in step 13), the instruction unit 72c causes the plurality of karaoke devices installed in the karaoke store L1 specified in step 10 to perform in step 12. It is instructed to transmit the singing history stored after the performance time indicated by the time information of the karaoke singing of the first music piece included in the list (transmission instruction of singing history, step 14). The karaoke device K1 transmits the singing history based on the instruction in step 14 (sending singing history, step 15). The other karaoke devices installed in the karaoke store L1 also transmit the singing history.

The second specifying unit 72d specifies one song history that matches the performance list generated in step 12 from the received plurality of song histories (identification of song history, step 16).

The transfer unit 72e transfers the song history specified in step 16 to the mobile terminal M1 of the user U1 (transfer of song history, step 17).

As is clear from the above, in the karaoke system 1 according to the present embodiment, a plurality of karaoke devices and the server device S are communicably connected. Each karaoke device includes song identification information for identifying a song played by karaoke, time information including a performance time at which the karaoke song is performed, and a singing history including a scoring result of evaluating the karaoke song accompanying the karaoke performance. Has a history processing unit 21b for storing. The server device S identifies the one karaoke store where the user is staying, based on the user position information indicating the whereabouts of the user acquired by the mobile terminal owned by the user. Based on the karaoke performance sound collected by the identification unit 72a and the mobile terminal, the music pieces that are being karaoke are sequentially specified, and a performance list of music pieces that have been karaoke while the user is using one karaoke device is generated. If the first karaoke store cannot be specified by the first specifying unit 72a after the generating unit 72b and the one karaoke store are specified, a plurality of karaoke devices installed in the one karaoke store. In response, the instruction unit 72c for instructing to transmit the singing history stored after the playing time indicated by the time information of the karaoke singing of the first song included in the playing list, and the performance from the received plurality of singing histories It has the 2nd specific part 72d which specifies one song history which matches a list, and the transfer part 72e which transfers the specified one song history to a user's portable terminal.

According to such a karaoke system 1, the user position information and the karaoke performance sound obtained from the user's mobile terminal are used, and the singing history accompanying the user's karaoke singing is recorded on the mobile terminal after the karaoke store is closed. Can be viewed on. Therefore, the user does not need to bother to log in to the karaoke system 1 to browse the singing history. That is, according to the karaoke system 1 according to the present embodiment, a user who sings a karaoke song without logging in can browse the song history.

<Modification 1>
In the above embodiment, the configuration has been described in which the user can browse the singing history after leaving the karaoke store. On the other hand, some users may want to browse the song history while using the karaoke device. Therefore, the karaoke system 1 according to the present modification enables a user who is using the karaoke device (a user who is not logged in to the karaoke system 1) to browse the singing history.

For example, suppose that the user U1 wants to browse the singing history while using the karaoke device K1. In this case, the user U1 selects a dedicated menu on the mobile terminal M1 on which the karaoke application is activated, and performs an operation input to request browsing of the song history.

When the transmission/reception processing unit 15c of the mobile terminal M1 receives the operation input, instead of transmitting the user position information acquired by the position acquisition unit 15a, a predetermined position indicating a position different from the position indicated by the user position information is transmitted. The position information is transmitted to the server device S. The predetermined position information is not included in the address list of the karaoke shop managed by the server device S. The predetermined position information is, for example, the position of the company in which the server device S is installed.

When such predetermined position information is received, the first specifying unit 72a cannot specify the karaoke store where the user is staying.

Therefore, the instruction unit 72c is stored after the playing time indicated by the time information of the karaoke singing of the first song included in the playing list for the plurality of karaoke devices installed in the karaoke store where the user was staying. Instruct to send the song history. After that, as in the above-described embodiment, the second identifying unit 72d identifies one song history that matches the performance list from the plurality of received song histories. The transfer unit 72e transfers the specified one song history to the mobile terminal of the user.

As described above, the karaoke system 1 according to the present modification includes the mobile terminal. When the mobile terminal receives an operation input requesting to browse the song history from the user, the transmission/reception processing unit that transmits predetermined position information indicating a position different from the position indicated by the user position information to the server device S. 15c.

According to such a karaoke system 1, it becomes possible for the user to browse the singing history even while the user is using the karaoke device.

<Modification 2>
In the above embodiment, the example in which the karaoke device K1 is used by the user U1 and the user U2 has been described. When karaoke singing is performed by multiple users in this way, the singing history transferred to the mobile terminal of each user includes the history in the order in which the karaoke singing was performed without distinguishing the users. ing. Therefore, in the present modification, an example will be described in which, when one singing history includes histories of a plurality of users, each user can easily browse his or her own singing history.

In this modification, the sound collection processing unit 15b controls the sound collection unit 14 to collect the karaoke song sound together with the karaoke performance sound. The karaoke singing sound is a sound generated when the user sings a karaoke song.
