  Here, the relationship between the music information SI and the segmented music information DSI will be described with reference to FIG. FIG. 4 is a conceptual diagram showing a temporal relationship between the music information SI and the segmented music information DSI. In FIG. 4, the reproduction start position of each piece of music information is set as a reference time (t = 0). In the following description, “music information SI” is used when the music information is collectively called, and “sorted music information DSI” is written when the music information is collectively called.

  When the music information A is described as an example, it can be seen that the segment music information Aa corresponds to the music information A from t = 0 to t = t1. It can also be seen that the segmented music information Ab corresponds to the music information A from t = t5 to t = t7.

  Similarly, the segmented music information Ba corresponds to the music information B from t = t2 to t = t4. The segmented music information Bb corresponds to the music information B from t = t8 to t = t9. The segmented music information Ca corresponds to the music information C from t = t3 to t = t6.

  Thus, the segmented music information DSI can be extracted using the time information of the music information SI. That is, the segmented music information DSI is a set of performance information extracted under a predetermined time condition.

  In addition, you may extract the division | segmentation music information DSI by designating the specific phrase in music information SI. For example, in the music information A, the music information A corresponding to the phrase (a plurality of performance sounds) described in the performance information of the main melody part may be extracted as the segmented music information Aa. For example, there may be a case where a phrase corresponding to the prelude is specified in the performance information of the main melody part.

  Next, a processing flow of the game system according to the present embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram showing a processing flow of the game system shown in FIG. In the following description, the card information is collectively referred to as “card information CI”.

  Note that in a game (hereinafter, referred to as “music card game”) performed in the game system according to the present embodiment, a game corresponding to a so-called “bunuki” game or “old maid” game of a card game is performed. However, the main difference between the “Banuki” game and the music card game is that the “Banuki” game uses a playing card, whereas the music card game associates the segmented music information DSI. The card information is used.

  Further, as a premise for explaining the processing in the game system according to the present embodiment, it is assumed that an IP address is registered in the host terminal 10H as identification information of each wireless terminal 10 participating in the game. In addition, it is assumed that the users of the wireless terminals 10 are gathered at the same place.

  First, the user of the wireless terminal 10 using the music card game needs to start an application program dedicated to the music card game. The user of each wireless terminal 10 may access the game server 20 via a web browser or the like, and download and install an application program. In the following description, the operation of the application program installed in each wireless terminal 10 will be described as the operation of the control unit 110, the card selection unit 111, and the music playback unit 112.

  Hereinafter, description will be given along the sequence diagram shown in FIG. The user of the host terminal 10H operates the operation unit 102 and inputs game setting information (step S1). The game setting information includes the number of wireless terminals 10 participating in the music card game, transmission destination information and identification information of each wireless terminal 10, order information specifying the order of the wireless terminals 10 that select card information CI, and the like. .

  Here, the operation of the user of the host terminal 10H when setting the order information will be described. FIG. 6 is a diagram showing a setting screen for setting the order information. The control unit 110 causes the monitor 101 to display a seat map corresponding to the number of users participating in the music card game as shown in FIG. Then, the user of the host terminal 10H operates the operation unit 102 and assigns identification information of each wireless terminal 10 to each seat 101A, 101A... Displayed on the monitor 101. Thereby, the user of the host terminal 10H can set the order information. In FIG. 6, arrows 101B, 101B,... Indicate the direction in which the card information CI is selected. For example, the wireless terminal 10 corresponding to the seat H selects any one of the card information CIs assigned to the wireless terminal 10 corresponding to the seat I.

  Next, the control part 110 of the host terminal 10H transmits game setting information to the game server 20 as a game setting notification (step S2). In the game server 20, after the communication unit 203 receives the game setting notification, the card management unit 211 generates card master information MI based on the received game setting notification (step S3).

  FIG. 7 is a diagram illustrating an example of the card master information MI generated by the card management unit 211. The card master information MI is a table in which card information CI corresponding to a playing card is recorded. The card management unit 211 generates card master information MI so that a plurality of card information CIs can be assigned to the wireless terminals 10 participating in the music card game.

  As shown in FIG. 7, each card information CI is given a unique ID. Each ID is recorded in association with the song name of the song information SI, the attribute information of the segmented song information DSI, and the terminal identification information. As attribute information of the segmented music information DSI, for example, the file name of the segmented music information DSI is recorded. Further, as the terminal identification information, for example, the IP address of each wireless terminal 10 is recorded.

  The card management unit 211 generates card master information MI based on two rules. The first rule is to associate the file names of the same segmented music information with the four card information CIs. In the example shown in FIG. 7, the segmented music information Aa is associated with ID1 card information, ID4 card information, and other two card information not shown.

  The second rule is that card information CI associated with the same segmented music information is assigned to different wireless terminals 10. As shown in FIG. 7, the card information of ID1 and the card information of ID4 associated with the segmented music information Aa are allocated to the client terminal 10C1 and the host terminal 10H, respectively.

  Returning to the description of FIG. The card management unit 211 extracts the card information CI for each terminal identification information from the generated card master information MI and transmits it to each wireless terminal 10 (step S4). For example, the card management unit 211 transmits card information such as ID2 and ID4 to the host terminal 10H, and transmits card information such as ID1 and ID8 to the client terminal 10C1. The card management unit 211 transmits the card information CI to each wireless terminal 10 and the preparation for the music card game is completed.

  Next, the user of each wireless terminal 10 operates the operation unit 102 to transmit a game start notification to the game server 20 (step S5).

  After confirming that the game start notification has been received from all the wireless terminals 10, the card management unit 211 of the game server 20 notifies the wireless terminal 10 that selects the card information CI based on the set order information. Is transmitted (step S6). The card selection notification includes identification information of a selected terminal that is a target for selecting the card information CI and an ID corresponding to the card information CI assigned to the selected terminal. Further, the card management unit 211 transmits a card selection notification to the selected terminal (step S7).

  In the following description, it is assumed that the card management unit 211 transmits a card selection notification to the host terminal 10H and transmits a card selection notification to the client terminal 10C1. Therefore, an ID (ID1 and ID8) corresponding to the card information CI assigned to the client terminal 10C1 is recorded in the card selection notification.

  The host terminal 10H executes the card selection process after receiving the card selection notification (step S8). Specifically, the card selection unit 111 of the host terminal 10H causes the monitor 101 to display a card image associated with the ID recorded in the card selection notification. At this time, the user of the host terminal 10H cannot recognize the ID from the card image displayed on the monitor 101.

  FIG. 8 is a schematic diagram showing the display contents of the monitor 101 during the card selection process. The user of the host terminal 10H operates the operation unit 102 to select one of the card images 101C, 101C,... Displayed on the monitor 101. When the card image 101D shown in FIG. 8 is selected, the card selection unit 111 of the host terminal 10H transmits an ID corresponding to the card image 101D to the game server 20 as a selection result notification (step S9).

  The game server 20 that has received the selection result notification executes a card determination process (step S10). Specifically, the determination unit 212 of the game server 20 determines whether any of the card information CI assigned to the host terminal 10H matches the card information corresponding to the selection result notification. .

  Here, the determination criterion of whether or not they match is the same segmented music for the card information corresponding to the selection result notification and any one of the card information CI assigned to the host terminal 10H. Whether the information is associated.

  Hereinafter, a case where the host terminal 10H selects a card image associated with ID1 and a case where a card image associated with ID8 is selected will be described separately.

  First, a case where the host terminal 10H selects a card image associated with ID1 will be described.

  The segmented music information associated with the card information of ID1 is segmented music information Aa as shown in FIG. In addition, among the card information CI assigned to the host terminal 10H, the segmented music information Aa is associated with the card information of ID4. Therefore, the determination unit 212 determines that the card information corresponding to the selection result notification (card information of ID1) matches the card information of ID4 assigned to the host terminal 10H. Then, the card management unit 211 deletes the description of the terminal identification information corresponding to the card information of ID1 and ID4 in the card master information MI.

  Next, a case where the host terminal 10H selects a card image associated with ID8 will be described.

  The segmented music information associated with the card information of ID8 is segmented music information Ca as shown in FIG. On the other hand, the card information CI assigned to the host terminal 10H is card information such as ID2 and ID4, but the segmented music information associated with the card information of ID2 and ID4 is the segmented music information Ba and Aa. Therefore, the determination unit 212 determines that the card information corresponding to the selection result notification (card information of ID8) does not match the card information CI assigned to the host terminal 10H. It is assumed that the piece music information Ca is not associated with the card information excluding ID2 and ID4 assigned to the host terminal 10H. Then, the card management unit 211 changes the description of the terminal identification information of the card master information MI corresponding to the card information of ID8 from the IP address of the client terminal 10C1 to the IP address of the host terminal 10H.

  The determination unit 212 transmits a determination notification to the host terminal 10H (step S11) and transmits a card information change notification to the client terminal 10C1 after the above-described card determination process (step S10) is completed (step S12).

  The determination notification transmitted to the host terminal 10H includes update information of the card information CI assigned to the host terminal 10H and audio information corresponding to the determination result.

  If the determination unit 212 determines that they match in step S10, the update information includes an instruction to delete the card information of ID4. Also, the audio information is segmented music information Aa corresponding to the card information of ID1 and ID4. Based on the update information, the card selection unit 111 of the host terminal 10H deletes the card information of ID4 from the storage unit 104, and the music playback unit 112 plays back the segmented music information Aa (step S13). As a result, the user of the host terminal 10H confirms that the card information corresponding to the selected card image matches any of the CIs of the card information assigned to the own terminal, and the number of card information CIs assigned to the host terminal 10H is It can be recognized that it has decreased by one.

  On the other hand, if the determination unit 212 determines that they do not match in step S10, the update information includes ID8 card information. The sound information is sound information in which a sound effect for notifying that they do not match is recorded. Based on the update information, the card selection unit 111 of the host terminal 10H newly stores the ID8 card information in the storage unit 104, and the music playback unit 112 records the sound effect after receiving the determination notification.

Is possible.

  Further, in the present embodiment, the description has been made as to determine whether or not the segmented music information DSI associated with the card information CI matches, but the present invention is not limited to this. For example, the determination unit 212 may determine whether or not the song names of the song information SI associated with the card information CI match. Thereby, since the probability that the card information CI matches can be increased, the music card game can be advanced speedily. Alternatively, other IDs indicating card information match / mismatch may be set in the card master information MI.

  In the present embodiment, the game server 20 has been described as managing the progress of the game, but the present invention is not limited to this. For example, the host terminal 10H may perform the process of the game server 20 described above.

  Moreover, in this Embodiment, only the display of the monitor 101 when each radio | wireless terminal 10 performs a card | curd selection process (step S8 shown in FIG. 5) is demonstrated. However, each wireless terminal 10 may cause the monitor 101 to display the card information CI assigned to the terminal itself when the card selection process is not performed. Moreover, you may reproduce | regenerate the division | segmentation music information DSI corresponding to each card information.

  In the present embodiment, the number of card information may be an odd number. At this time, the specific piece of card information is associated with the piece of music information DSI or the piece of music information SI that does not match any of the pieces of piece of music information associated with the other card information. In this case, the specific card information corresponds to the joker of the “Banuki” game. As a result, the above-described music card game can be enjoyed with the same feeling as a normal “Banuki” game. In addition, when each of the wireless terminals 10 selects the specific card information described above, the wireless terminal 10 may reproduce the segmented music information associated with the specific card information.

  In the above embodiment, the IP address is used as the identification information of the wireless terminal 10, but the present invention is not limited to this. For example, when the wireless terminal 10 is a mobile phone, the identification information may be a telephone number or a mail address.

There is assignment information for assigning to each wireless terminal 10.

  At this time, the user of the host terminal 10H sets the allocation information so that the segmented melody information DLI is randomly allocated to each wireless terminal 10. The wireless terminal 10 to which the user of the host terminal 10H is assigned the segmented melody information DLI may be set. However, since the host terminal 10H also participates in the karaoke game, the segmented melody information DLI is randomly assigned to each wireless terminal 10. It is preferable to assign to

  The generation unit 221 of the game server 20 extracts and generates segmented melody information DLI, accompaniment information AI, and lyrics information TI based on setting information set by the host terminal 10H. The generated segmented melody information DLI, accompaniment information AI, and lyrics information TI are stored in the karaoke data storage unit 204. The distribution unit 222 assigns the segmented melody information DLI generated based on the assignment information to each wireless terminal 10. Then, the distribution unit 222 transmits the storage destination URLs of the division melody information DLI, the accompaniment information AI, and the lyrics information TI to each wireless terminal 10 by mail.

  When the user of each wireless terminal 10 receives the mail in which the storage destination URL is described, the user accesses the storage destination URL via a web browser or the like, and downloads the segmented melody information DLI, the accompaniment information AI, and the lyrics information TI. Note that the distribution unit 222 of the game server 20 may transmit an email attached with the division melody information DLI or the like to each wireless terminal 10.

  The user of each wireless terminal 10 operates the operation unit 102 to start an application program. Further, the user of each wireless terminal 10 causes the activated application program to read the segment melody information DLI, the accompaniment information AI, and the lyrics information TI. At this time, the user of each wireless terminal 10 cannot recognize which phrase the assigned segmental melody information DLI belongs to.

  As described above, when each wireless terminal 10 finishes reading the segmented melody information DLI and the like, the karaoke game starts. In the following description, the operation of the application program in each wireless terminal 10 will be described as the operation of the control unit 120 and the music playback unit 121.

  Here, the operation of each wireless terminal 10 and the operation of the user of each wireless terminal 10 during the progress of the karaoke game will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of a state in which the division melody information DLI is assigned to each wireless terminal 10.

  As shown in FIG. 11, the melody information LI is divided into divided melody information DLI1 to DLI5. The phrases corresponding to the segmented melody information DLI1 to DLI5 are referred to as phrases 1 to 5, respectively. As shown in FIG. 11, the segmented melody information DLI1 is assigned to the host terminal 10H. The segment melody information DLI4 is assigned to the client terminal 10C1. The segment melody information DLI2 and DLI5 are assigned to the client terminal 10C2. The segment melody information DLI3 is assigned to the client terminal 10C3. Accompaniment information AI is assigned to each wireless terminal 10. That is, all the radio terminals 10 reproduce the accompaniment information AI.

  The karaoke game is started when the user of the host terminal 10H operates the operation unit 102 to instruct the start of the karaoke game. In response to this instruction, the host terminal 10H transmits a start signal to each client terminal 10C. The start signal includes a reference time at which the wireless terminals 10 start playing the accompaniment information AI all at once. Based on the absolute time information acquired from the reference time acquisition unit 107 and the start signal, each wireless terminal 10 starts reproducing the accompaniment information AI simultaneously at the reference time recorded in the start signal.

  When the wireless unit 105 of each wireless terminal 10 has a communication function such as wireless LAN or Bluetooth, the start signal is directly transmitted from the host terminal 10H to the client terminal 10C. Further, the host terminal 10H may transmit a start signal to the client terminal 10C via the game server 20.

  As shown in FIG. 11, the segmented melody information DLI1 corresponding to the first phrase of the melody information LI is assigned to the host terminal 10H. Therefore, the music playback unit 121 of the host terminal 10H plays back the accompaniment information AI and the segmented melody information DLI1 at the same time. In addition, the control unit 120 of the host terminal 10H vibrates the vibration unit 106 simultaneously with the reproduction of the accompaniment information AI and the segmented melody information DLI1, and displays lyrics information TI corresponding to the segmented melody information DLI1 on the monitor 101. Thereby, the host terminal 10H notifies the user of the host terminal 10H that he is in charge of the phrase 1. The user of the host terminal 10H sings a song based on the lyrics information TI displayed on the monitor 101 in accordance with the segmented melody information DLI1 to be reproduced.

  When the reproduction time of the accompaniment information AI approaches the reproduction start time (t = t21) described in the segmented melody information DLI2, the control unit 120 of the client terminal 10C2 vibrates the vibration unit 106. Further, the control unit 120 of the client terminal 10C2 displays the lyrics information TI corresponding to the segmented melody information DLI2 on the monitor 101. Thereby, the client terminal 10C2 notifies the user of the client terminal 10C2 that it is in charge of singing the phrase 2.

  Then, the music playback unit 121 of the client terminal 10C2 starts playback of the segmented melody information DLI2 at the same time as the playback time of the accompaniment information AI reaches t = t21. The user of the client terminal 10C2 sings a song based on the lyrics information TI displayed on the monitor 101 in accordance with the segmented melody information DLI2 to be reproduced.

  Hereinafter, when each wireless terminal 10 approaches the reproduction start time described in the segmented melody information DLI to which the reproduction time of the accompaniment information AI is assigned, the wireless terminal 10 performs the same operation as that of the client terminal 10C2 described above, and Notify the user that they are responsible for the phrase. Then, when the playback time of the accompaniment information AI reaches the playback start time described in the segmented melody information DLI, the music playback unit 121 of each wireless terminal 10 starts playback of the segmented melody information DLI. By repeating this, the segmented melody information DLI is reproduced continuously, and as a result, the entire melody information LI is reproduced.

  Note that the control unit 120 of each wireless terminal 10 displays the area 101E shown in FIG. 11 on the monitor 101 while the accompaniment information AI is being reproduced. At this time, the playback position of the accompaniment information AI is indicated by the pointer P. Thereby, the user of each radio | wireless terminal 10 can recognize the division | segmentation of the phrase of melody information LI, and the reproduction | regeneration position of melody information LI.

  As described above, the game system according to the present embodiment generates segmented melody information DLI obtained by segmenting melodic information LI, which is a part sung by the user, with a phrase or the like, and allocates segmented melodic information DLI to each wireless terminal 10. . Each wireless terminal 10 reproduces the accompaniment information AI synchronously and reproduces the assigned segmental melody information DLI. The user of each wireless terminal 10 sings a song based on the reproduced piecewise melody information DLI and the displayed lyrics information TI. Thereby, the game system which concerns on this Embodiment can provide the karaoke game in which a some user can enjoy karaoke simultaneously using one music information SI.

  Further, the game system according to the present embodiment can dynamically generate segmented melody information DLI according to the number of users participating in the karaoke game. Thereby, the karaoke game which is not restrict | limited to the number of users who participate in a karaoke game can be provided.

  In the present embodiment, the accompaniment information AI has been described as being synchronized and reproduced from all the wireless terminals 10, but the present invention is not limited to this. For example, only the host terminal 10H may reproduce the accompaniment information AI. Or each radio | wireless terminal 10 may reproduce | regenerate only the accompaniment information AI corresponding to the same phrase as the allocated division | segmentation melodic information DLI.

  Further, in the present embodiment, it has been described that each wireless terminal 10 reproduces the segmented melody information DLI at the same time that the reproduction time of the accompaniment information AI becomes the reproduction start time described in the segmented melody information DLI. It is not limited. For example, instead of playing the segmented melody information DLI, the control unit 120 of each wireless terminal 10 may display the musical score and the lyrics information TI corresponding to the segmented melody information DLI on the monitor 101. Alternatively, the control unit 120 of each wireless terminal 10 may cause the monitor 101 to display either the musical score corresponding to the segmented melody information DLI or the lyrics information TI. In this case, since it is necessary for the user of each wireless terminal 10 to completely memorize the melody or lyrics of the music used in the karaoke game, it is possible to provide a karaoke game with a high degree of difficulty.

  Further, in the present embodiment, each wireless terminal 10 has been described as displaying the lyrics information TI included in the music information SI on the monitor 101. However, the present invention is not limited to this. For example, lyric information different from the lyric information TI may be displayed on the monitor 101. That is, the game property of a karaoke game can be improved by displaying on the monitor 101 the replacement song for the original lyrics of the music information SI and allowing the user of each wireless terminal 10 to sing the replacement song.

  Further, in the present embodiment, each wireless terminal 10 has been described as displaying the lyrics information TI included in the music information SI on the monitor 101. However, the present invention is not limited to this. For example, each wireless terminal 10 does not have to display the lyrics information TI on the monitor 101. In this case, since the user of each wireless terminal 10 cannot sing while watching the lyrics information TI, the game performance of the karaoke game can be improved.

  In the present embodiment, the division melody information DLI is described as being assigned to one radio terminal 10, but the present invention is not limited to this. For example, the same segmented melody information DLI may be assigned to a plurality of wireless terminals 10. Thereby, since a several user can chorus the phrase corresponding to the division | segmentation melody information DLI allocated to the some radio | wireless terminal 10, in a karaoke game, a user's sense of solidarity can be improved.

  In the present embodiment, each wireless terminal 10 has been described as vibrating the vibrating unit 106 before reproducing the segmented melody information DLI. However, the present invention is not limited to this. For example, the wireless terminal 10 may include an LED instead of the vibration unit 106. In this case, the control unit 120 of each wireless terminal 10 may notify the user of the wireless terminal 10 that it is in charge of the next phrase by blinking the LED before reproducing the segmented melody information DLI.

  In the present embodiment, the e-mail address of each wireless terminal 10 has been described as being registered in the host terminal 10H. However, the present invention is not limited to this. For example, identification information such as the IP address of each wireless terminal 10 may be registered in the host terminal 10H.

  In the present embodiment, the radio clock and the GPS clock are used as the synchronization reference time. However, the present invention is not limited to this. For example, the host terminal 10H may synchronize by sending a synchronization signal to the client terminal 10C at regular intervals during reproduction of the accompaniment information AI. Specifically, first, the host terminal 10H transmits a synchronization offset confirmation signal to the client terminal 10C. The client terminal 10C transmits a response signal to the synchronization offset confirmation signal to the host terminal 10H. The host terminal 10H determines the synchronization offset information of each client terminal 10C based on the delay time of the response signal received from each client terminal 10C, and transmits it to each client terminal 10C. Each client terminal 10C adjusts the synchronization signal transmitted from the host terminal 10H using the synchronization offset information. Thereby, it is possible to synchronize all the radio terminals 10.

That is, the game system according to the present embodiment includes a plurality of wireless terminals 10, 10.

  As in the first embodiment, one of the plurality of wireless terminals 10, 10,... Operates as the host terminal 10H, and the other wireless terminals 10 operate as the client terminal 10C. The host terminal 10H is different from the client terminal 10C in that various settings of the music game such as selection of music information used for the music game are performed.

  The game server 20 is a server that extracts accompaniment information and segmented performance information from the music information selected by the host terminal 10H and sets the information in each wireless terminal 10.

  In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The description will focus on parts that are different from those in the first embodiment. .

  Next, the configuration of radio terminal 10 according to the present embodiment will be described.

  FIG. 12 is a block diagram of radio terminal 10 according to the present embodiment. That is, it is a functional block diagram common to the host terminal 10H and the client terminal 10C. The wireless terminal 10 includes a monitor 101, an operation unit 102, a speaker 103, a storage unit 104, a wireless unit 105, and a control unit 130.

  The control unit 130 includes a CPU, a RAM, and the like, and performs overall control of the wireless terminal 10. The control unit 130 also includes a music playback unit 131. The music playback unit 131 plays back the accompaniment information AI and the segmented performance information DPI transmitted from the game server 20.

  The monitor 101 is used for various information displays such as an operation screen display during game progress. The storage unit 104 stores accompaniment information AI and segmented performance information DPI transmitted from the game server 20.

  Next, the configuration of the game server 20 according to the present embodiment will be described.

  FIG. 13 is a block diagram of game server 20 according to the present embodiment. The game server 20 includes a communication unit 203, a segmented performance information holding unit 205, and a control unit 230.

  The control unit 230 includes a CPU, a RAM, and the like, and performs overall control of the game server 20. Further, the control unit 230 includes a generation unit 231, a distribution unit 232, and a determination unit 233. The generation unit 231 extracts and generates accompaniment information AI and segmented performance information DPI from the music information SI based on setting information set by the host terminal 10H. Distribution unit 232 assigns accompaniment information AI and segmented performance information DPI to each wireless terminal 10 based on the setting information, and transmits storage destination information of accompaniment information AI and segmented performance information DPI to each wireless terminal 10. The determination unit 233 determines whether or not the reproduction start time of the segmented performance information DPI designated by each wireless terminal 10 matches the reproduction start time described in the segmented performance information DPI.

  The segmented performance information holding unit 205 stores the music information SI selected by the host terminal 10H, the accompaniment information AI and the segmented performance information DPI generated by the generating unit 231.

  Next, the relationship between the music information SI and the segmented performance information DPI will be described in detail.

  As described above, the music information SI is a set of performance information corresponding to a plurality of performance parts. That is, the music information SI is information describing all performance information of all performance parts. The segmented performance information DPI is information obtained by segmenting the performance information. In the segmented performance information DPI, a playback start time is recorded when the playback start position of the music information SI is set as a reference time.

  The segmented performance information DPI is generated by segmenting the performance information for each phrase composed of a plurality of performance sounds described in the performance information or for each measure described in the performance information. Moreover, you may divide and generate performance information according to the time information which music information SI has.

  Next, a processing flow of the game system according to the present embodiment will be described.

  In the following description, it is assumed that the users of the wireless terminals 10 using the game system according to the present embodiment are gathered at the same place. Further, it is assumed that the mail address of each wireless terminal 10 is registered in the host terminal 10H.

  First, the user of each wireless terminal 10 has to operate the operation unit 102 to install an application program dedicated to music games. The user of each wireless terminal 10 may access the game server 20 via a web browser or the like and download an application program.

  Next, the user of the host terminal 10H accesses the game server 20 via a web browser or the like and inputs music game setting information. The music game setting information includes selection information of music information SI used in the music game, the number of wireless terminals 10 participating in the music game, classification information for dividing performance information, the mail address of each wireless terminal 10, and the like. is there.

  The generation unit 231 of the game server 20 extracts the accompaniment information AI and the segmented performance information DPI from the music information SI based on the setting information set by the host terminal 10H and the extraction condition table held by the generation unit 231.

  Here, the extraction condition table held by the generation unit 231 will be described with reference to FIG. FIG. 14 is a diagram showing an extraction condition table for extracting the segment performance information DPI from the music information SI.

  As shown in FIG. 14, it is assumed that the music information SI is composed of five performance parts from a track T1 to a track T5. Therefore, the music information SI includes performance information corresponding to the tracks T1 to T5. Further, as shown in FIG. 14, the serial number of each measure from the reproduction start position of the music information SI is described in the extraction condition table as measure A, measure B,. That is, the extraction condition table shown in FIG. 14 describes the extraction conditions for dividing the performance information into each measure and generating the divided performance information DPI.

  The track T1 is, for example, a performance part that the bass is in charge of, and is defined as an accompaniment part. Therefore, the track T1 is extracted from the music information SI as the accompaniment information AI without being divided into bars.

  In measure A, tracks T2, T3, and T5 are assigned to wireless terminals 10 with ID = 1, ID = 2, and ID = 4, respectively. On the other hand, the track T4 is not assigned to any wireless terminal 10. In bar B, tracks T3 and T4 are assigned to wireless terminals 10 with ID = 2 and ID = 3, respectively. On the other hand, the tracks T2 and T5 are not assigned to any wireless terminal. In the following, in each measure C, D, E..., The ID of the wireless terminal 10 assigned for each track is defined. In addition, although there is a track to which no ID is assigned in each measure, an ID may be assigned to all the tracks in each measure.

  Further, FIG. 14 shows a case where the number of wireless terminals 10 is 4, but the generation unit 231 has an extraction condition table corresponding to the number of wireless terminals 10. Thereby, even if the number of the wireless terminals 10 participating in the music game changes, it becomes possible to flexibly assign the segmented performance information DPI to the wireless terminals 10. In addition, although the example divided | segmented for every measure is shown in FIG. 14, the production | generation part 231 may have the extraction condition table divided for every phrase.

  Hereinafter, the description returns to the processing of the game system according to the present embodiment. The generation unit 231 of the game server 20 selects an optimum extraction condition table based on the number of wireless terminals 10 input as setting information and the classification information. Then, the generation unit 231 randomly assigns the ID described in the selected extraction condition table to each wireless terminal 10. Note that the user of the host terminal 10H may operate the operation unit 102 to assign an ID to each wireless terminal 10. However, since the host terminal 10H also participates in the music game, the generation unit 231 applies to each wireless terminal 10. It is desirable to assign an ID at random.

  Then, the generation unit 231 extracts and generates accompaniment information AI and segmented performance information DPI from the music information SI based on the selected extraction condition table. The generated accompaniment information AI and segmented performance information DPI are stored in the segmented performance information holding unit 205.

  Next, the distribution unit 232 notifies the storage destination URL of the generated accompaniment information AI and the segmented performance information DPI by sending an email to each wireless terminal 10 to which the ID is assigned. After each wireless terminal 10 receives the mail, the user of each wireless terminal 10 starts an application program. The user of each wireless terminal 10 accesses the game server 20 via the application program, and acquires accompaniment information AI and segmented performance information DPI.

The user of each wireless terminal 10 can designate the reproduction position of the accompaniment information AI by moving the reproduction position instruction pointer 303 displayed under the accompaniment information progress bar 302.

  The icon pasting bar 304 displays time information of the music information SI based on the time axis. In the icon pasting bar 304, the left end in FIG. 15 indicates the playback start position, and the right end indicates the playback end position.

  The icons 305, 305,... Are obtained by graphically displaying the divided performance information DPI assigned to each wireless terminal 10 with an image of a musical instrument corresponding to the divided performance information DPI. Each icon 305 is associated with one piece of segmented performance information DPI. However, the user of each wireless terminal 10 cannot confirm the playback start time described in the segmented performance information DPI displayed as the icon 305.

  Next, a user operation when the music game is executed will be described with reference to FIG. First, the user of each wireless terminal 10 operates the operation unit 102 to select one of the icons 305, 305. The user of each wireless terminal 10 inputs reproduction instruction information while the icon 305 is selected, whereby segment performance information DPI (hereinafter referred to as “selected performance information”) corresponding to the selected icon 305 is stored in the music reproduction unit 131. To play. Thereby, the user of each radio | wireless terminal 10 can confirm the reproduction | regeneration content of selection performance information. Further, the user of each wireless terminal 10 may operate the operation unit 102 to reproduce the accompaniment information AI from the reproduction position indicated by the reproduction position instruction pointer 303. Thereby, the user of each radio | wireless terminal 10 can confirm the reproduction | regeneration content of accompaniment information AI. Then, the user of each wireless terminal 10 determines which portion in the music information SI corresponds to the reproduction start time of the selected performance information, using the reproduction contents of the selected performance information and the accompaniment information AI as a clue.

  Next, the user of each wireless terminal 10 pastes the icon 305 of the target performance information on the icon pasting bar 304 at the time when the user determines that it is the playback start time of the target performance information (hereinafter referred to as “determination time”). Specify by adding. Specifically, after selecting the icon 305, the user of each wireless terminal 10 operates the operation unit 102 to move the position of the pointer 306 shown below the icon pasting bar 304 to a position corresponding to the determination time. The user can designate the time corresponding to the position of the pointer 306 as the determination time of the target performance information by operating the operation unit 102 and inputting the decision information.

  The user of each wireless terminal 10 inputs the determination time of the segmented performance information DPI associated with each icon 305 by performing the above operation on each icon 305. Note that the user must perform an operation for designating the determination time of the segmented performance information DPI within the remaining time displayed in the area 301.

  When the time limit is reached, the control unit 130 of each wireless terminal 10 notifies the user that the music game has ended. And the control part 130 of each radio | wireless terminal 10 transmits the determination time of each division | segmentation performance information DPI to the game server 20 as determination information.

  After the control unit 230 of the game server 20 receives the determination information transmitted from all the wireless terminals 10, the determination unit 233 determines that the determination time of each pieced performance information DPI described in the decision information is the pieced piece performance information DPI. It is determined whether or not it matches the described playback start time.

  When the determination time and the reproduction start time described in the segmented performance information DPI match in all the segmented performance information DPI, the determination unit 233 notifies the wireless terminal 10 that all the determination times match. Then, the music information SI is transmitted to all the wireless terminals 10. On the other hand, when the determination time does not coincide with the reproduction start time in some or all of the segmented performance information DPI, the determination unit 233 notifies the wireless terminal 10 that they do not coincide. At this time, the determination unit 233 may transmit a determination rate match rate or the like to the wireless terminal 10.

  As described above, the game system according to the present embodiment generates segmented performance information DPI in which the performance information constituting the music information SI is divided by each measure and assigns it to each wireless terminal 10. The user of each wireless terminal 10 determines the playback start time described in the assigned segmented performance information DPI based on the playback contents of the segmented performance information DPI and the accompaniment information AI. The game server 20 determines whether or not the time determined by the user matches the time described in the segmented performance information DPI. Thereby, even a user who cannot play a musical instrument can input the determination time of the segmented performance information DPI corresponding to each phrase of the performance part and configure the music information SI, which is different from a normal music ensemble. You can enjoy creating music in a way.

  In the present embodiment, it has been described that all wireless terminals 10 participating in the music game input the determination time of the segmented performance information DPI. However, the present invention is not limited to this. For example, when there are a large number of wireless terminals 10 participating in a music game, the above-described music game may be performed in a group competition with four wireless terminals 10 as one group. In this case, the rank of each group may be determined based on the matching rate of the determination times or the time until all the determination times match.

  Further, in the present embodiment, the description has been made assuming that the divided performance information DPI obtained by dividing the performance information is used, but the present invention is not limited to this. For example, segmented music information obtained by segmenting the music information SI by a main melody phrase or each measure may be assigned to each wireless terminal 10. In this case, since the difficulty level of the music game described in this embodiment is reduced, even a beginner can enjoy it.

  Further, in the present embodiment, it has been described that the determination time of the target performance information is input using the pointer 306, but the present invention is not limited to this. For example, even if the determination time of the division performance information DPI is designated by dividing the icon pasting bar 304 into a plurality of areas based on the divisions described in the extraction condition table and designating the area where the icon 305 is pasted.
