  On this active user top screen, by selecting “Search for a song”, a search based on a singer name and a song name can be performed as in the case of a conventional song book. When “My Room” is selected, a music search specialized for the active user can be performed using the My Uta table in the user information.

  Now, the karaoke system and the karaoke apparatus of the present embodiment will be described with reference to the drawings. In general, a karaoke apparatus is provided with a key change function for changing a pitch for the purpose of singing assistance. In this key change function, the pitch of the accompaniment to be played is changed based on the key adjustment value designated by the user.

  In the present embodiment, the key adjustment value specified by the user is acquired for each song and for each user, and the song-specific key adjustment value and the user-specific key adjustment value are determined based on the acquired key adjustment value. Yes.

  FIG. 7 is a flowchart showing music selection processing according to the embodiment of the present invention, and particularly shows music selection processing for a user who is not logged in (guest user). When a music piece is designated using the remote control device 1 (S401), various information for confirming the music piece such as the music name, singer name, and singing of the designated music piece is displayed on the display unit 11 as a music confirmation screen ( S402). Moreover, it is also possible to specify a key adjustment value on this music confirmation screen, and when the user knows his / her favorite pitch, the user makes a reservation by specifying the key adjustment value on this screen. The reserved music is registered in the reservation list and the performance processing is executed by the MIDI sound source 26 as a performance means (S403).

  When the performance process ends, history information regarding the music is transmitted to the karaoke host 5 (S404). In the case of this guest user's music selection process, the history information includes a music identifier and a designated key adjustment value. In addition, the performance time related to the performance date may be included. FIG. 10 shows an example of history information received by the karaoke host 5 (S421). In the figure, what is described as “Guest” in the user ID column is the history information collected by this music selection process. The key adjustment value transmitted as the history information is appropriately determined by an algorithm from those specified on the music confirmation screen and those changed by user operation during performance. For example, when the key adjustment value is changed several times immediately after the start of performance, it is conceivable to use the key adjustment value with the longest specified time as the history information.

  The history information of each guest user obtained in this way is counted for each song together with the history information of the logged-in user. For example, the key adjustment value that is used most frequently is determined as the key adjustment value for each song of the song. The Rukoto.

  FIG. 8 is a flowchart showing the music selection process according to the embodiment of the present invention, which is the music selection process when the active user selects music. When a song is designated by the active user (S201), the user ID of the active user and the song identifier of the designated song are transmitted to the karaoke host 5 to inquire key information (S202). This key information is a user-specific key adjustment value and a music-specific key adjustment value determined based on the history information, and details of the determination will be described in detail later.

  The commander 2 or the remote control device 1 that has received the key information (S202) performs a recommended key determination process (S300) that determines a recommended key based on the original music key adjustment value that specifies the original music key of the music and the received key information. Execute. This recommended key is a key adjustment value suitable for singing the music designated by the active user who is executing the music selection process, and details of the determination process will be described in detail later.

  When the determination of the recommended key is completed, the same music confirmation screen display as that of the guest user is executed (S204). FIG. 15 shows an example of a music confirmation screen according to the embodiment of the present invention. In the figure, when Mr. A who is an active user designates the song “Natsu no Umi”, the key adjustment value “−2” determined in the recommended key determination process is displayed in the key setting column. When “reservation” is operated in this state, the music “Summer Sea” is reserved with the recommended key adjustment value “−2”.

  On the music confirmation screen, the key adjustment value can be changed. By operating “Change” in the lower right corner of the key setting column, a pop-up screen (key setting screen) for key adjustment value setting is opened. FIG. 16 is a diagram illustrating a key setting screen according to an embodiment of the present invention, in which a user who wants to change a key adjustment value changes a key adjustment value by operating a button indicating a pitch. Can do. By finishing the change and returning to the music confirmation screen and operating “reservation”, the music reservation is executed based on the changed key adjustment value.

  The reserved music is registered in the reservation table as reservation information including a music identifier, a user ID, and a key adjustment value. In the performance process, the reservation information is sequentially read out and the MIDI sound source 26 as a performance means executes the performance (S205). When the performance of the reserved music ends, the history information about the played music is transmitted to the karaoke host 5 for transmission, as in the music selection process for the guest. The history information of the music selection process in the case of the active user includes the user ID of the user who specified the music in addition to the music identifier and the key adjustment value. The karaoke host that has acquired the history information updates the database in the storage unit 1 based on the history information. FIG. 10 shows an example of history information acquired by the karaoke host 5. In the figure, the history information collected by the music selection process is a user ID column with a number as a user ID.

  As described with reference to FIG. 5, user information transmitted and received for login and logout is exchanged between the remote controller 1 or the commander 2 and the host 5. A procedure in the case where the remote controller 1 and the commander 2 are separate, the login and logout operations are performed by the remote controller 1 and the performance of music is performed by the commander 2 is shown below. The remote controller 1, the commander 2 and the host 5 store each other's IP address in advance, so that they can communicate with each other.

  At the time of music selection by an active user, a user ID is associated with the designated music name, and the commander 2 is sent to the commander 2 via the infrared communication unit 19 or the wireless LAN communication unit 16 so that the commander 2 is assigned to the user ID. You can know the corresponding reserved music.

  Then, the performance is started by the commander 2, and history information such as the score value of the music, the key change value, and the performance end record is returned from the commander 2 to the remote control device 1, and the remote control 1 displays the history information corresponding to the user ID. Can be recorded for each performance song.

  Thereafter, the remote control device 1 collectively transmits history information corresponding to the user ID to the host 5 when the user logs out. The history information obtained by the guest user's music selection may be transmitted together with the history information of the active user.

As described above, in the present embodiment (FIGS. 7 and 8), the update of the history information of the user and the update of the history information of the music by the whole user (the user having the user ID and the guest user) are updated at the time of logout. The

  Without being limited to such an embodiment, the history information recorded in the karaoke host 5 may be sequentially updated every time the music performance is completed. Specifically, every time the music performance by the commander 2 is completed, the history information of the music corresponding to the user ID or the history information of the music played by the guest user is transmitted from the commander 2 to the karaoke without using the remote controller 1. By directly transmitting to the host 5, history information stored on the karaoke host 5 side is sequentially updated.

  Even in such a form, the user ID or the guest user and the history information of the song are associated with each other, the history information for each user ID stored in the storage unit 51 of the karaoke host 5 and the entire user (user ID) It is possible to correctly update the history information of songs by a user and a guest user.

  Now, the recommended key determination process (S300) important in the present invention will be described in detail with reference to FIGS. FIG. 9 is a flowchart showing recommended key determination processing according to the embodiment of the present invention. In the recommended key determination process of the present embodiment, if there are key adjustment values for the specified music in the my song table or history table described in the user information of FIG. 4, they are preferentially used as recommended keys. To do.

  In S301, first, it is determined whether or not there is a key adjustment value for the music specified in the My Uta table. If a key adjustment value has been registered in the My Uta table, it is determined as a recommended key (S309). In S302, the history information is referred to and the presence / absence of the key adjustment value of the designated music is determined. If it exists in the history information, the key adjustment value specified for the music is determined as a recommended key (S310). When this history information is used, there may be a plurality of key adjustment values for the designated music. In that case, it is conceivable to select the latest key adjustment value by referring to the performance date and time accompanying the history information.

  In the case where there is neither in the my song table nor in the history information, that is, in the case of the music that the user sings for the first time, the recommended key is determined in the process described below. This process may be performed not only for the first song to be sung but also for all the designated songs. First, the user-specific key adjustment value A is acquired. The user-specific key adjustment value A is included in the key information transmitted from the karaoke host 5 described with reference to FIG. 8. In this embodiment, the user-specific key adjustment value A is based on the history information collected by the karaoke host 5. It has been decided.

  The user-specific key adjustment value A is determined based on the key adjustment value of the corresponding user in the history information shown in FIG. FIG. 11 is a diagram showing the history information for each user, and is a diagram in which the key adjustment values for the corresponding user are tabulated from the history information. In the present embodiment, the key adjustment value that is specified most frequently (most frequently) is determined as the key adjustment value A for each user. Therefore, in the example shown on the left (user ID: 0001), the key adjustment value “1” is used, and in the example shown on the right (user ID: 0002), the key adjustment value “3” is used as the user-specific key adjustment value A. It is determined.

  The method for determining the user-specific key adjustment value A is not limited to this example, and various methods such as determination based on the distribution of the number of uses can be employed. In addition, the key adjustment values acquired during a certain past period or the past certain number of songs may be used for counting the number of uses. For example, as a result of the user practicing, the range in which the user can sing may be expanded. When old information is used, the accuracy of determining recommended keys may be degraded. Therefore, the key adjustment value A for each user can be determined in accordance with the singing tendency of the singer by using the key adjustment value acquired for a certain period in the past or for a certain number of songs in the past.

  In S304, acquisition of the music-specific key adjustment value B and the original music key adjustment value C is executed. First, the music-specific key adjustment value B is information included in the key information as described with reference to FIG. 8, and the key adjustment value determined based on the history information as with the user-specific key adjustment value A. It is. FIG. 12 is a diagram showing the history information for each song, and is a diagram in which key adjustment values for the image music designated from the history information are tabulated. In the present embodiment, the key adjustment value with the most specified number of times (the most frequent) is determined as the key adjustment value B for each music piece. Therefore, in the example shown on the left (music ID: A0001), the key adjustment value “−2” is used, and in the example shown on the right (music ID: A0002), the key adjustment value “0” is the key adjustment value B for each music. As determined. Similar to the user-specific key adjustment value A, a determination method can be adopted as appropriate, and key adjustment values acquired for a certain period in the past or a certain number of performances in the past may be used.

  In S304, the original music key adjustment value C is also acquired. In karaoke, a user who is unfamiliar with singing may perform at a pitch different from the pitch when a professional actually sings. The original music key adjustment value C is a key adjustment value for changing to a pitch when a professional singer actually sings on a CD or the like. FIG. 13 is a diagram showing a data structure of music information used in this embodiment. As shown in the drawing, the music information is composed of a combination of performance information (MIDI data) played by the MIDI sound source 26 and the music related information. In addition to the original music key adjustment value, the music related information includes a music identifier for specifying a music, lyrics, a music name, and the like. If the key adjustment value is “0” during performance, the performance information is played without changing the pitch. On the other hand, when the performance with the original music key is designated, the performance information is performed by transposing by the original music key adjustment value.

  As can be seen from FIG. 8, determination of the user-specific key adjustment value A and the music-specific key adjustment value B is performed on the karaoke host 5 side. It may be performed on the commander 2 or the remote control device 1 side. In this case, history information necessary for determining the adjustment values A and B is transmitted to the commander 2 and the remote control device 1. The original music key adjustment value C is also included in the music information in advance, but may be acquired by inquiring the karaoke host 5.

  Thus, the recommended key is determined based on the original music key adjustment value C acquired from the music information, the user-specific key adjustment value A obtained by collecting the history information, and the music-specific key adjustment value B. Here, there may be a case where the music-specific key adjustment value B cannot be acquired due to circumstances such as music being just delivered. Therefore, in this embodiment, when it is determined that the music-specific key adjustment value B cannot be acquired (S305), the standard key, that is, the key adjustment value “0” is determined as the recommended key.

  If the song-specific key adjustment value B is obtained, the user-specific key adjustment value A is compared with the song-specific key adjustment value B and the original song key adjustment value C (S306). Then, one of the original music key adjustment values C is determined as a recommended key (S307).

  FIG. 14 is a diagram for explaining the recommended key determination process according to the embodiment of the present invention. In this embodiment, the key adjustment value B or C having a small difference with respect to the user-specific key adjustment value A is used as a recommended key. Has been decided. The user-specific key adjustment value A is a key adjustment value that indicates a user's tendency to sing, such as high singing and low singing. The music-specific key adjustment value B is a key adjustment value indicating a pitch that many users can easily sing. The original music key adjustment value C is a pitch that is actually used by the singer, and many users desire to sing at this pitch if possible.

In this embodiment, for example, even for a song that has not been sung so far, based on this user's singing tendency, a pitch that many users can easily sing, or a pitch that a singer actually uses is used. The closest one is determined as the recommended key.

  FIG. 14A shows a case where the user-specific key adjustment value A is “−1”, the music-specific key adjustment value B is “−2”, and the original music key adjustment value C is “2”. In this case, since the difference between the adjustment value A and the adjustment value B is “1” and the difference between the adjustment value A and the adjustment value C is “3”, the music key adjustment value B that is close in distance is determined as the recommended key. .

  FIG. 14B shows a case where the user-specific key adjustment value A is “2”, the music-specific key adjustment value B is “0”, and the original music key adjustment value C is “1”. Since the difference between the adjustment value A and the adjustment value B is “2” and the difference between the adjustment value A and the adjustment value C is “1”, the original music key adjustment value C that is close in distance is determined as the recommended key.

  On the other hand, the difference between the adjustment value A and the adjustment value B and the difference between the adjustment value A and the adjustment value C may be equal. FIG. 14C shows such a case, where the user-specific key adjustment value A is “0”, the music-specific key adjustment value B is “−2”, and the original music key adjustment value C is “ In this case, both of the differences are “2”. In such a case, a high (or low) pitch is preferentially selected, a music key adjustment value B (or original music key adjustment value C) is preferentially selected, or the standard key “ It is conceivable to determine the recommended key according to various agreements such as “0”.

  The determined recommended key is displayed in the key setting field of the music confirmation screen as shown in FIG. This example shows a music confirmation screen in the case of FIG. 14A, and the recommended key is “−2”. When the key change is designated, the key setting screen shown in FIG. 16 is opened, but a comment indicating the adjustment value is provided at the positions of the music key adjustment value B and the original music key adjustment value C. It is attached. A similar comment may be displayed as a reference when performing key adjustment for the user-specific key adjustment value A (in this case, “−1”).

  In the present embodiment, the setting of the recommended key is also confirmed on the music confirmation screen as described above. However, when the music is designated, the reservation is automatically executed with the recommended key. Good.

  Note that the present invention is not limited to these embodiments, and embodiments configured by appropriately combining the configurations of the respective embodiments also fall within the scope of the present invention.
