Description

  The present invention relates to a karaoke system having an electronic table of contents function, and more particularly, to a karaoke system capable of narrowing down and displaying a list of songs to be selected according to a predetermined selection criterion when a user selects a song. Is.

  Conventionally, when a karaoke user selects a desired piece of music, the user selects the desired piece of music using a book-like table of contents and inputs the piece of music ID assigned to the piece of music to the remote control device. However, in recent years, it has become common to select music using a remote control device called an electronic table of contents with a GUI function. This electronic table of contents has a music search function, and by inputting a singer name, music title, release year, genre, etc., a list of search results is displayed on an input / output display unit such as a liquid crystal display device. It is like that. The user can easily find the desired music compared to the book of contents by searching for the desired music from the search results displayed in the list and specifying the music selection. have.

  By the way, when the music is searched using the electronic table of contents, all of the music including the search keyword are displayed as a list of music selection targets. At this time, if the number of songs displayed in a list is small, it is possible to find a desired song quickly. However, if the number of songs displayed in a list is large, a search result is displayed over a plurality of pages to find a desired song. It may take time.

In addition, when a new song of an artist that the user likes is announced, there is a request to sing the artist's new song as soon as possible, and technology that allows the user to select and sing such a song as soon as possible Is disclosed (see Patent Document 1).
The technique described in Patent Document 1 is that, when a user performs a new music data extraction operation in a state in which a user designates an arbitrary piece of music from hits in a predetermined search mode, the same artist as the designated piece of music If there is new music data belonging to, it has a function of displaying it preferentially.

JP-A-2005-283806

  By the way, the technique described in the above-mentioned patent document 1 can easily and effectively know the new song data of the artist that the user likes when searching for a song using an electronic table of contents, and can sing the song quickly. An excellent effect can be achieved.

However, the technique described in the above-mentioned patent document 1 finds a desired music as soon as possible when there are too many songs to be selected in a general search or an artist who frequently announces new songs. In that respect, further ingenuity was necessary.
Moreover, if the user always sings only the same music, the repertoire does not increase and the singing becomes rutted. Therefore, there is a desire to increase the repertoire by challenging music that you are not familiar with. On the other hand, there is a demand for singing music that he is used to and is good at.

  The present invention has been proposed in view of the above-described circumstances, and it is an object of the present invention to provide a karaoke system having an electronic table of contents function capable of quickly searching for a desired music piece when a user selects music. To do.

The karaoke system having the electronic table of contents function of the present invention has been proposed to achieve the above-described object, and has the following features.
That is, the karaoke system having the electronic table of contents function of the present invention searches for music desired by a user who has logged in to any karaoke performance terminal, displays a list on the display unit, and specifies from the displayed search results. A karaoke system having an electronic table of contents function for reserving and registering recorded music, comprising user ID acquisition means, performance frequency management means for each user, and music selection display control means To do.

  Here, the user ID acquisition means is means for acquiring the user ID of the user who has logged in to any karaoke performance terminal. In addition, each user's performance frequency management means each time a user logs in to a system at an arbitrary karaoke performance terminal, the performance frequency of the music played before logging out, This is a means for managing the user ID associated with the user. In addition, the music selection display control means, when the user selects music using the electronic table of contents function, the performance frequency of each music managed by the performance frequency management means for each user based on the user ID of the user. Is obtained, and only music pieces whose performance frequency satisfies a predetermined criterion are displayed as a list on the display unit as music selection targets.

Here, in the performance frequency management in the performance frequency management means for each user, when a music piece selected by linking to the user ID is played, it is considered that the user has sung and the user ID is When a music piece that is not selected and linked to is played, it is considered that the user has listened.
Further, “the performance frequency satisfies a predetermined criterion” is a concept including both the case where the performance frequency is less than the reference value and the case where the performance frequency is greater than or equal to the reference value.

  In the karaoke system having the electronic table of contents function of the present invention, when a user selects music using the electronic table of contents function, the performance frequency acquired based on the user ID of the user satisfies a predetermined standard. Only the music can be displayed as the music selection target.

Therefore, when displaying only the music whose performance frequency is less than the predetermined reference value as the music selection target, the user frequently sings or listens when performing music selection using the electronic contents function. Since only the songs that have not been displayed are displayed in a list, the number of songs to be selected is reduced, and the songs can be selected easily.
For this reason, users can quickly find songs that they have not sung or are unfamiliar with, and challenge the songs to increase their repertoire, making it easier to sing using the karaoke system. Can be increased.

On the other hand, when displaying only songs whose performance frequency is equal to or higher than a predetermined reference value as a song selection target, the user frequently sings or listens when performing song selection using the electronic table of contents function. Since only the music pieces that are currently being displayed are displayed in a list, the number of music pieces to be selected can be reduced and the music selection can be easily performed.
For this reason, users can quickly find songs they are singing or are familiar to, and sing familiar songs that they are good at, increasing the fun of singing using the karaoke system Can be made.

Hereinafter, an embodiment of a karaoke system having the electronic contents main function of the present invention will be described with reference to the drawings.
The karaoke system according to the embodiment of the present invention searches for a music piece desired by a user, displays a list on the display unit, and an electronic table of contents function for reserving and registering a music piece specified from the displayed search results It has.

FIG. 4 is a flowchart showing a procedure of music selection display control when performing challenge music selection.
The challenge music selection is a music selection mode in which only music whose performance frequency is less than a predetermined reference value is displayed so that music selection is possible, and a music that is unfamiliar to the user who selects music can be challenged.

  In the karaoke system of this embodiment, as shown in FIG. 4, prior to the music selection display control, the user ID acquisition means 33 acquires the user ID of the user who has logged into the karaoke performance terminal 13 (S1). ). Then, the host device 11 is accessed, and user information including the performance frequency for each song is acquired based on the acquired user ID (S2). The acquired performance history of each user (data in which the song ID and the performance frequency are associated) is stored in the remote input / output terminal 32 as a login user performance frequency list 32d.

  When a user who selects music operates a challenge button (see FIG. 7) displayed on the input / output display unit to start challenge music selection in association with the user ID (S3), based on the input conditions. The music is searched (S4), and the performance frequency of the user is compared with a predetermined reference value for each searched music (S5). And it is judged whether the performance frequency of the searched music is less than a predetermined reference value (S6). Here, if the performance frequency of the searched music is less than the predetermined reference value, the music is displayed (S7). If the performance frequency of the searched music is equal to or higher than the predetermined reference value, the music is displayed. (S8). In the present embodiment, the performance frequency is regarded as “0” for music that does not exist in the login user performance frequency list 32d.

  Then, it is determined whether or not the performance frequency has been determined for all the searched music pieces (S9). If there is a music piece for which the determination of the performance frequency has not been completed, determination processing (S5 to S8) is performed. repeat. On the other hand, when the performance frequency is determined for all the searched music pieces, the music pieces to be displayed are displayed in a list on the input / output display unit (S10). In addition, when it is not challenge music selection, music selection display control is not performed.

A specific example of challenge music selection display control will be described with reference to FIGS. 5 and 6. FIG. 5 is an explanatory diagram of the music index database, and FIG. 6 is an explanatory diagram showing a procedure for determining the playing frequency when performing the challenge music selection.
When the user performs a music selection operation using the electronic table of contents function of the remote input / output terminal 32, the music index database 32c is referred to, and the corresponding music is extracted as a search result. For example, when searching using a singer name as a keyword, a song ID corresponding to the corresponding singer name code is extracted with reference to the song index database 32c shown in FIG.

  Then, as shown in FIG. 6, the function of the music selection display control means 32b (FIG. 3) refers to the performance frequency list 32d for each logged-in user (FIG. 3) and selects a music from the extracted music IDs. A musical piece with a performance frequency of the musical piece based on the user ID being performed is selected to be a display target. Here, description will be made assuming that the reference is set to less than “5”.

  In the example shown in FIG. 6, referring to the music index database 32c (FIG. 5) for the singer with the singer name code “A0001”, the music IDs “*** 7”, “*** 8”, “** 10”, “** 26”, “** 42”, “* 125”, “* 213”, “* 307”, and the like are extracted as search results. Further, referring to the performance count list 32d for each logged-in user with the user ID “****** A” (FIG. 3), the song IDs “*** 2”, “*** 4”, “*” “** 6”, “*** 7”, “*** 8”, “*** 9”, and “** 10” are extracted as the performance history during login.

  Here, the user with the user ID “****** A” has the song IDs “*** 7”, “*** 8”, “*” among the songs with the singer name code “A0001”. * Singing or listening to "10" music. Of the music pieces with the music IDs “*** 7”, “*** 8”, and “** 10”, the music with the performance frequency less than “5” is the music of “** 10”. The music with the ID “*** 10” is the display target, and the music with the music IDs “*** 7” and “*** 8” is excluded from the display target. In this case, since the music with the music ID “*** 26” or the like does not exist in the performance history during login of the user with the user ID “****** A”, the performance frequency is regarded as “0”. To be displayed.

  The reference value is not particularly limited and can be changed and set as appropriate. In this case, the reference value may be changed based on the designation by the user. Specifically, as shown in FIG. 7, a reference value setting area is displayed on the input / output display section of the remote input / output terminal 32, and music selection display control is performed based on the reference value designated by the user.

The familiar music selection is a music selection mode in which only music having a performance frequency equal to or higher than a predetermined reference value is displayed so that music selection is possible, and a music familiar to a user who selects music can be selected.

  Similarly to the challenge music selection described above, in the familiar music selection, prior to the music selection display control, the user ID acquisition means 33 acquires the user ID of the user who has logged into the karaoke performance terminal 13 (S11), The host device 11 is accessed, and user information including the performance frequency for each music piece is acquired based on the acquired user ID (S12). The acquired performance history of each user (data in which the song ID and the performance frequency are associated) is stored in the remote input / output terminal 32 as a login user performance frequency list 32d.

  When a user who selects music operates a familiar button (see FIG. 7) displayed in a list on the input / output display unit, and familiar music selection is started in association with the user ID (S13), the input is performed. The music is searched based on the conditions (S14), and the performance frequency of the user is compared with a predetermined reference value for each searched music (S15). And it is judged whether the performance frequency of the searched music is more than a predetermined reference value (S16). Here, if the performance frequency of the searched music is greater than or equal to a predetermined reference value, the music is displayed (S17). If the performance frequency of the searched music is less than the predetermined reference value, the music is displayed. (S18). In the present embodiment, the performance frequency is regarded as “0” for music that does not exist in the login user performance frequency list 32d.

  Then, it is determined whether or not the performance frequency has been determined for all the searched music pieces (S19). If there is a music piece for which the determination of the performance frequency has not been completed, determination processing (S15 to S18) is performed. repeat. On the other hand, when the performance frequency is determined for all the searched music pieces, the music pieces to be displayed are displayed in a list on the input / output display unit (S20). If the music selection is not familiar, the music selection display control is not performed.

A specific example of familiar song selection display control will be described with reference to FIGS. FIG. 9 is an explanatory diagram showing a procedure for determining the playing frequency when familiar music selection is performed.
When the user performs a music selection operation using the electronic table of contents function of the remote input / output terminal 32, the music index database 32c is referred to, and the corresponding music is extracted as a search result. For example, when searching using a singer name as a keyword, a song ID corresponding to the corresponding singer name code is extracted with reference to the song index database 32c shown in FIG.

  Then, as shown in FIG. 9, the function of the music selection display control means 32b (FIG. 3) refers to the performance frequency list 32d for each logged-in user (FIG. 3) and selects a music from the extracted music IDs. A music piece having a performance frequency of a music piece based on the user ID being performed is selected and set as a display target. Here, description will be made assuming that the reference is set to “5” or more.

  In the example shown in FIG. 9, referring to the music index database 32c (FIG. 5) for the singer with the singer name code “A0001”, the music IDs “*** 7”, “*** 8”, “** 10”, “** 26”, “** 42”, “* 125”, “* 213”, “* 307”, and the like are extracted as search results. Further, referring to the performance count list 32d for each logged-in user with the user ID “****** A” (FIG. 3), the song IDs “*** 2”, “*** 4”, “*” “** 6”, “*** 7”, “*** 8”, “*** 9”, and “** 10” are extracted as the performance history during login.

  Here, the user with the user ID “****** A” has the song IDs “*** 7”, “*** 8”, “*” among the songs with the singer name code “A0001”. * Singing or listening to "10" music. Of the music pieces with the music IDs “*** 7”, “*** 8”, and “*** 10”, the music with a performance frequency of “5” or more is “*** 7”, “*** 8”. Therefore, the music with the music IDs “*** 7” and “*** 8” is the display target, and the music with the music ID “*** 10” is excluded from the display target.

In this case, since the music with the music ID “*** 26” or the like does not exist in the performance history during the login of the user with the user ID “****** A”, the performance frequency is regarded as “0”. Excluded from the display target.
The reference value may be changed as in the case of the challenge music selection described above.
