A user who visits a karaoke store inputs authentication information composed of his / her user identification information and password, or causes the IC card reader provided in the remote control device 1 or the like to read the authentication information stored in the IC card. Thus, the authentication process (S101) is executed. The karaoke device 2 or the remote control device 1 transmits authentication information to the host device 5 (S102), and the host device 5 that has received the authentication information extracts user information of the corresponding user from the database stored in the storage unit 51. (S121), it transmits to the karaoke device 2 or the remote control device 1 inquired (S122).

  On the karaoke device 2 side that has received the user information (S103), various service processes such as a music reservation process and a music reproduction process are provided based on the received user information (S104). When logout is requested by the user (S105), the service processing is interrupted, and various histories (logs) generated during the service processing or user information reflecting setting changes by the user are transmitted to the host device 5 (S106). . Here, user information may transmit only the updated difference other than transmitting all information. In the host device 5 that has received the user information (S123), the database stored in the storage unit 51 is updated based on the received user information (S124).

  The flow from the authentication process (login process) to logout has been described above. However, in the karaoke apparatus 2 and the remote control apparatus 1 of the present embodiment, a plurality of authenticated users (authenticated users) log in at the same time. It is possible to use in the state. By using the user interface described in FIG. 2, it is possible to switch and use a user who provides a service (hereinafter referred to as “active user”).

  FIG. 5 is a diagram illustrating an active user top screen according to the present embodiment. As shown in this figure, when a plurality of users are logged in, the logged-in user column 103 displays the logged-in images 103a to 103e (face portions in this embodiment) of the logged-in user. In the logged-in user column 103, the user whose background is highlighted (white) on the right end is the active user 103e (Mr. A), and in the state shown in FIG. The service using the user information 103e is being executed. On this active user top screen, a search based on a singer name and a song name can be performed by selecting “Find a song”.

  On the active user top screen of FIG. 5, the user can perform a music selection process by inputting a song name or a part of a singer's name by operating a button labeled “Find a song”. Become. FIG. 8 is a flowchart showing the music selection process of this embodiment. This music selection process is a process executed by the remote control device 1. When the music selection process starts, the range information in the user information is acquired for the active user who is operating (S101). Then, based on the acquired sound range information, the predicted sound range of the user is calculated (S102).

  FIG. 9 is a diagram for explaining calculation of the estimated sound range of the present embodiment. In the present embodiment, the current estimated sound range is calculated based on the first measurement sound range two weeks ago and the second measurement sound range one week ago. For example, as for the first measurement range, the highest pitch value and the lowest pitch value belonging to the measurement date (from 14 days to 8 days before) belonging to the first measurement range are obtained from the information included in the range information, and the respective averages are taken. Is calculated. In addition, the second measurement sound range is obtained by obtaining the highest pitch value and the lowest pitch value belonging to the measurement date (from 7 days before to 1 day before) belonging to the second estimated sound range in the information included in the range information, and taking the respective averages, etc. Is calculated.

  In FIG. 9, in order to make the explanation easy to understand, the minimum pitch value is constant, and only the maximum pitch value is changed. The estimated sound range is calculated by extending the slope formed between the first measurement sound range and the second measurement sound range as it is. That is, in the present embodiment, the current estimated sound range is calculated using the first measurement sound range two weeks ago and the second measurement sound range one week ago. FIG. 9A shows a case where the second estimated sound range is expanded with respect to the first estimated sound range, that is, the maximum pitch value that can be output by the user is improved. FIG. 9B shows a case where there is no change in the first estimated sound range and the second estimated sound range, that is, a case where there is no change in the sound range that can be output by the user. FIG. 9C shows a case where the second estimated sound range is reduced with respect to the first estimated sound range, that is, the maximum pitch value that the user can output is reduced.

  In the present embodiment, using the estimated sound range calculated in this way, music having a singing pitch within the estimated sound range is presented to the user as recommended music. Thus, by presenting the recommended music to the user, the user can select a music that has a high possibility of singing. Moreover, it is preferable that the recommended music is a music having a singing pitch within the expected growth that is a difference between the estimated sound range and the second estimated sound range. With such a configuration, it becomes possible for a user to challenge a song that has not been able to be sung until now (a song pitch of the song could not be output).

  When a song selection condition such as a song name or a singer name is designated by the user (S103: Yes), the remote control device 1 refers to a database for music search stored in the memory 14 and sets the designated song selection condition. A suitable music piece is extracted (S104). Then, from the extracted music, the user's predicted range calculated in S102 is used, and a song whose singing pitch is included in the predicted range is extracted as a recommended song (S105). Then, the extracted recommended music is displayed on the touch panel monitor 11 to be presented to the user (S106).

  FIG. 10 shows a recommended music presentation screen of the present embodiment. This recommended music presentation screen is a recommended music presentation screen for Mr. A who is an active user, and shows a case where a singer name search is performed as a music selection condition. In this example, “singer name A” is input as the music selection condition indicating the singer name. On the recommended song presentation screen, a plurality of songs of singer name A are displayed. In the present embodiment, the items are displayed in order of the degree of challenge for the user A. Here, the degree of challenge will be described. FIG. 11 shows the singing range of the song A to E of the singer name A and the estimated range of the user A, the second estimated range, and the singer name A. Here, in order to simplify the explanation, the lower limit of each sound range is constant. As described above, when the user's singing ability is improved, that is, when the estimated sound range is expanded with respect to the second measured sound range, the difference between the estimated sound range and the second measured sound range is the expected growth of the user.

  In the present embodiment, music included in the calculated estimated sound range is extracted as recommended music. Therefore, among the music A to the music E shown in FIG. 11, the music E whose singing sound range is out of the estimated sound range of the user A is not recommended. On the other hand, music A to music D whose singing sound range is within the estimated sound range of user A are displayed as recommended objects on the recommended music presentation screen. At this time, in the present embodiment, the degree of challenge of the music is determined based on the usage degree of the user A's expected growth for the singing pitch of the music. Since the song A includes the singing range within the first measurement range, the degree of challenge is one star. Since the music B has a singing range of half of the expected growth, the degree of challenge is two stars. Music C and music D have a singing sound range that is substantially the same as the estimated sound range. In this case, the degree of challenge is determined based on how much the expected growth amount is used in terms of singing pitch or singing time.

  FIG. 12 is a diagram illustrating determination of the challenge level according to the present embodiment. This figure shows the time change of the singing pitch for music C and music D. FIG. The singing pitch can be acquired from the main melody included in the music information. Comparing the singing pitches of the music C and the music D, the music C uses the user A's expected growth for the time t1, whereas the music D has the user A's expected growth longer than the time t1. It can be seen that time t2 is used. Therefore, the degree of challenge of the music D with a high usage rate for the expected growth is set to four stars, and the degree of challenge of the music C with a low usage rate for the expected growth is determined as three stars and presented to the user. Yes. As described above, the degree of challenge can be defined by using the usage rate for the expected growth with respect to the singing pitch of the music. As the usage rate, at least one of the staying time within the expected growth amount and the pitch is considered.

  When the music is designated by the user on the recommended music presentation screen shown in FIG. 10 (S107: Yes), the remote control device 1 displays the music confirmation screen and allows the user to check whether there is no mistake in the music to be selected. . FIG. 13 shows a music confirmation screen of the present embodiment. In the music confirmation screen of the present embodiment, the degree of challenge for the selected user, as described above, is shown in addition to the music related information such as the singer name, the song name, and the lyrics of the singing. The user confirms information related to such music and operates the reservation button 104 when singing (S109: Yes) to reserve the music for the karaoke apparatus 2. When the reservation is made, the remote control device 1 transmits reservation information including the music identification information of the determined music to the karaoke device 2. The karaoke apparatus 2 that has received the reservation information adds the reservation information to the reservation list, and executes a music reproduction process for sequentially reproducing the music added on the reservation list.

  As described above, the music selection process by the remote control device 1 has been described for the embodiment of the present invention. However, this music selection process can be executed not only by the remote control device 1 but also by the karaoke device 2. That is, the remote control device 1 or the karaoke device 2 can function as a music selection device in the present invention. Currently, a service is provided to allow a mobile terminal to function as a remote control device of the karaoke device 2 by installing a program (application) on a mobile terminal such as a smart phone possessed by the user. It is good also as recommending the music according to the change of a user's singing ability by making this program (program for music selection in this invention) perform the music selection process mentioned above.
