Description

  The present invention relates to a karaoke remote control having a display unit, and more particularly to a karaoke remote control capable of effectively presenting karaoke music using the display unit.

  Conventionally, instead of a thick karaoke table of contents, a karaoke remote controller (electronic table of contents) having a display unit has been widely used. Since such a remote control has a calculation function, a storage function, and a communication function like a computer, a search for karaoke music (hereinafter also simply referred to as “music”) is performed using these functions. The result is displayed on the display unit. For example, Patent Literature 1 below discloses a karaoke remote controller that searches for music using a singer's singing history and displays the search result on a display unit.

JP 2006-337408 A

  The current online karaoke system can distribute over 100,000 songs, but only a part of the songs are actually sung. For this reason, even if a song is newly created, it may not be sung and the attractiveness of the song may not be noticed, and a karaoke remote controller that can effectively present a song that has not been sung is desired.

  In response to this request, for example, by searching for and presenting an unsung song among the songs of an artist that the singer likes, singing of the unsung song can be promoted. In particular, by singing all the songs of an artist, the singer can sing all songs (hereinafter referred to as “perfect”) by displaying a special image or changing to a special display state. It is thought that it will come to sing unsung music. Furthermore, if the number of perfect artists is displayed, it is considered that many unsung songs will be sung in an attempt to achieve perfect for many artists.

  By the way, in the online karaoke system, new songs are created one after another, and more songs can be sung. Therefore, even if a perfect performance is achieved for an artist, when a new score (new song, coupling song, etc.) is created after that, the perfect state (hereinafter simply referred to as “perfect state”) is lost. Therefore, there is a demand for a singer who wants to maintain the perfect state to know that the perfect state has been lost.

  An object of this invention is to provide the karaoke remote control etc. which can show a karaoke music effectively using a display part.

  In order to achieve the above object, an invention according to claim 1 is a karaoke remote control having a control unit and a display unit and capable of communicating with a center, wherein the control unit receives login information received from a user from the center. Singing history information indicating which artist's song has been sung by the user from the center, and singing all songs at the time of the user's previous logout based on the singing history information. It is determined whether there is any new music that can be sung after the user's previous logout, among the music of the specified artist When the artist of the new music is selected as the target artist and the name of the target artist is displayed on the display unit, The artist's name is displayed on the display unit in a first display state indicating that all songs have been sung, and then the name of the target artist is displayed in a second display state indicating that all songs have not been sung. It is changed and displayed on the display unit.

According to the invention according to claim 1, based on the singing history information, the artist who has already sung all songs at the time of the user's previous logout is specified, and among the songs of the specified artist, the previous song of the user By determining whether there is a new song that can be sung after logout, it is possible to select an artist who is no longer in a perfect state. Then, the artist's name is first displayed in a first state indicating that all songs have been sung, and then changed to a second display state indicating that all songs have not been sung. On the other hand, it is possible to effectively present that it is no longer in a perfect state.
The first state can be a state in which a predetermined mark is displayed next to the artist's name. Further, the second state can be a state in which the predetermined mark is not displayed. Further, when changing from the first state to the second state, a predetermined effect (for example, an effect in which the predetermined mark gradually disappears, an effect in which a sound is produced, etc.) may be accompanied.
Thereby, since a singer's singing range spreads, the music which is not sung can be reduced. In addition, since the user sings many songs for the purpose of increasing the number of perfect artists and maintaining the perfect state, the profit of the karaoke business can be improved.

  The invention according to claim 2 is the karaoke remote control according to claim 1, wherein the control unit prioritizes the names of the target artists when displaying the names of a plurality of artists included in the singing history information. It is characterized by displaying on the said display part.

According to the second aspect of the present invention, when a plurality of artists included in the singing history are displayed, the artists that are no longer in the perfect state are preferentially displayed.
For example, when the number of artists that can be displayed in the list of the display unit is six and the number of artists included in the singing history is eight, the artist that is no longer in the perfect state is displayed first. Also, the artist that is no longer in the perfect state may be displayed at the top of the list.
Thus, in addition to the effect of the invention according to claim 1, an artist who is no longer in a perfect state can be effectively presented, so that the user can be effectively encouraged to sing unsung music.

  The invention according to claim 3 is the karaoke remote control according to claim 1 or claim 2, wherein the control unit is different from the second display state for an artist who has never sung all songs. The artist who is displayed on the display unit in the third display state and has already sung all songs is displayed on the display unit in the first display state, and the other artists are displayed in the second display state. It displays on the said display part, It is characterized by the above-mentioned.

  Thereby, in addition to the effect of the invention according to claim 1 or claim 2, the artist who is not in the perfect state after entering the perfect state and the artist who has never been in the perfect state are displayed in different states. This makes it possible to effectively present an artist who is no longer in a perfect state, and can effectively prompt the user to sing unsung music.

  According to the present invention, karaoke music can be effectively presented using the display unit.

Specifically, the control unit 111 refers to the singer data, acquires the previous logout date and time, and then refers to the table of contents main data and the artist's music (new music) having a delivery date later than the logout date and time. ) Exists.

If it is determined that there is a new song (S36: YES), the control unit 111 turns on the “target artist flag” of the artist ID specified in S35 in S37. However, the perfect flag remains “ON” and is not changed. Hereinafter, an artist whose target artist flag is ON is referred to as a target artist.
In S38, the control unit 111 determines whether or not the above processing has been performed on all the artist IDs included in the perfect list.

  If there is an artist ID that has not been subjected to the above process (S38: NO), the control unit 111 shifts the process to S35. On the other hand, when the above process is performed for all artist IDs (S38: YES), the control unit 111 ends the target artist selection process.

[Artist display processing]
Next, the artist display process executed in S20 of the remote control side process will be specifically described. FIG. 9 is a flowchart of artist display processing.

  First, in S51, the control unit 111 determines an artist name to be displayed on the artist display units 151 to 156 of the second operation screen. As shown in FIG. 8, since the number of artist display sections is six, if the number of artists registered in “Favorites” is larger than that, which artist name is displayed on the second operation screen. It is necessary to choose.

In the present embodiment, the artist name of an artist (target artist) that is no longer in a perfect state because new music has been distributed after the previous login is preferentially displayed on the display unit 113. Thereby, it is possible to effectively present to the singer the name of an artist who has newly created (created) an unsung song. Note that the control unit 111 can extract the target artist by referring to the target artist flag. Further, the names of artists other than the target artist may be selected in descending order of the number of singing or in order of Japanese syllabary.
Note that the artist name of the artist whose perfect flag is “RE-OFF” may be preferentially displayed.

In S52, the control unit 111 displays the artist determined in S51 in a predetermined display state. At this time, the display mode is determined with reference to the perfect flag and the master flag.
When the perfect flag is “ON”, the control unit 111 displays the artist name on the display unit 113 in the first display state. When the master flag is also “ON”, the control unit 111 also displays a master mark 171 next to the artist name.
When the perfect flag is “RE-OFF”, the control unit 111 displays the artist name on the display unit 113 in the second display state.
When the perfect flag is “OFF”, the control unit 111 displays the artist name on the display unit 113 in the third display state.

FIG. 10 is an example of the layout of the second operation screen in S52. In the following description, it is assumed that the perfect state has been lost because the new “Mischildren” was distributed after the previous login.
As shown in FIG. 10, the artist name “Misterchildren” is preferentially displayed on the artist display section 151 which is the top row of the artist display section. In the artist display section 151, “mischildren” is displayed in the first display state although the perfect state has been lost. In the master number display area 161 and the perfect number display area 162, the numbers before the perfect state is lost are displayed.

Returning to FIG.
In S53, the control unit 111 determines whether or not the target artist exists. Specifically, the control unit 111 determines whether there is an artist whose target artist flag is ON among the artists displayed on the second operation screen.

  When the target artist exists (S53: YES), the control unit 111 performs an effect process in S54. In the effect process, the control unit 111 deletes the perfect mark 172 (next to the master mark 171 when the master mark 171 is displayed) displayed next to the artist name of the target artist, and displays the second display state. Change to display. Further, the control unit 111 changes the artist's perfect flag to “RE-OFF”. Also, the control unit 111 subtracts and displays the numbers of the master number display area 161 and the perfect number display area 162.

FIG. 11 is an example of the layout of the second operation screen in S54. As shown in FIG. 11, the artist name “Misterchildren” is displayed in the second display state.
In addition, when changing from the first display state to the second display state, a predetermined effect (for example, an effect in which the predetermined mark gradually disappears, an effect in which a sound is produced, etc.) may be accompanied.
Thereby, the singer can easily recognize that the artist who was in the perfect state is no longer in the perfect state.

[Processing on the commander 120 side]
Next, the commander side process executed on the commander 120 side will be specifically described. The commander-side processing program is stored in the ROM in the control unit 121 and is repeatedly executed by the CPU in the control unit 121. FIG. 12 is a flowchart of the commander side processing.

  In S <b> 71, the control unit 121 determines whether request information has been received from the remote controller 110. When it is determined that the request information has not been received (S71: NO), the control unit 111 ends the commander side process.

  On the other hand, if it is determined that the request information has been received (S71: YES), the video / audio reproduction unit 123 plays the karaoke song specified by the song ID included in the request information in S72, and the control unit 121. Marks the singing content.

  In S <b> 73, after the performance of the karaoke music piece is completed, the control unit 121 transmits performance result information to the remote controller 110. The performance result information includes the sung music ID, singer ID, and scoring data.

  In S <b> 74, the control unit 121 transmits performance result information to the remote controller 110. The performance result information includes the sung music ID, singer ID, and scoring data.

[Processing on the center 200 side]
Next, the center side process executed on the center 200 side will be specifically described. The center processing program is stored in the ROM in the control unit 201 and is repeatedly executed by the CPU in the control unit 201. FIG. 13 is a flowchart of the center side process.

  In step S <b> 91, the control unit 201 determines whether login information has been received from the remote controller 110. When determining that the login information has not been received (S91: NO), the control unit 201 shifts the process to S93. On the other hand, when determining that the login information has been received (S91: YES), the control unit 201 shifts the process to S92.

  In S92, the control unit 201 performs a login authentication process, and after authentication, refers to the first singer information database 203 and the second singer information database 204, nickname, singing song ID, singing date and time, and perfect flag, The master flag is transmitted to the remote controller 110 as singer information.

  In step S <b> 93, the control unit 201 determines whether singing history request information has been received from the remote controller 110. When determining that the singing history request information has not been received (S93: NO), the control unit 201 shifts the process to S95. On the other hand, when determining that the singing history request information has been received (S93: YES), the control unit 201 shifts the process to S94.

In S <b> 94, the control unit 201 refers to the second singer information database 204 and transmits singing history information to the remote controller 110.
In step S <b> 95, the control unit 201 determines whether performance result information has been received from the commander 120. When determining that the performance result information has not been received (S95: NO), the control unit 201 shifts the process to S97.

  On the other hand, when it is determined that the performance result information has been received (S95: YES), the control unit 201 shifts the process to S96. In S <b> 96, the control unit 201 updates the first singer information database 203. Moreover, the control part 201 updates the 2nd singer information database 204 with the update of the 1st singer information database 203. FIG.

  In step S97, the control unit 201 determines whether flag update information has been received from the remote controller 110. If it is determined that the flag update information has not been received (S97: NO), the control unit 201 ends the center-side process. On the other hand, when determining that the flag update information has been received (S97: YES), the control unit 201 shifts the process to S98.

  In S98, the control unit 201 updates the perfect flag and the master flag in the second singer information database 204.

  As described above, in the present embodiment, when the artist name is displayed on the display unit 113, the control unit 111 “is in a perfect state”, “the perfect state has been lost after the previous logout”, or “always perfect. One of the three states “not in state” is determined, and the artist name display state is determined according to the determination result. Thereby, the remote control 110 of this embodiment can present effectively the artist in which an unsung song exists.

  When the artist name of the artist whose perfect state has been lost after the previous logout is displayed on the display unit 113, the artist name is first displayed on the display unit 113 in the first display state, and then the second display state is displayed. Since it changes and displays on the display part 113, the artist in which an unsung song exists can be shown more effectively.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. For example, the first singer information database 203 and the second singer information database 204 may be configured as one singer information database.

Further, each flowchart described above is merely an example, and the processing may be realized by another flowchart as long as a result equivalent to the processing of each flowchart can be obtained.
The present invention can also be realized as a method related to the above-described remote controller, a program for causing a computer to execute the method, a recording medium on which the program is recorded, and the like.
