Description

  The present invention relates to a karaoke system having a game function capable of executing a game related to music played on a karaoke performance terminal among a plurality of users who have logged in to any karaoke performance terminal.

  In recent years, karaoke performance terminals have been developed which have a number of additional functions in addition to the basic function of playing music and displaying lyrics telop and background images. As such an additional function, for example, a karaoke performance terminal having an intro quiz function has been proposed (see Patent Document 1 and Patent Document 2).

  The karaoke performance terminal described in Patent Literature 1 includes an intro hit question song order registration mode and an intro hit quiz execution mode. And, in the intro assignment song order registration mode, a plurality of song numbers input by the user are accepted, each song number is organized and stored in a question song order list, and only the questioner can see On the display. In addition, in the intro quiz execution mode, the name of the music of the next performance order in the list of the order of questions is displayed on a specific display, and in response to a predetermined operation input, the intro part of the music of the next performance order is displayed. Reproduce for a predetermined short time and output from the speaker.

  Further, the karaoke performance terminal described in Patent Literature 2 is based on means for switching to a creation table for a questioned song table by user input, and attribute data attached to each song in the karaoke database in the creation mode for the questioned song table. There are provided means for designating the music category by user input, and means for selecting a predetermined number of question songs belonging to the designated music category and storing the song IDs in the question song table.

JP-A-10-78785 JP 2002-41071 A

  By the way, the intro guessing quiz allows the intro part of a song to be played for a short period of time and guesses the title of the song. In conventional techniques, the choice of a question is left to the discretion of the questioner.

  However, the user who has logged in to any karaoke performance terminal is not necessarily equivalent to the questioner regarding the degree of music recognition. That is, the degree of recognition is different between a user who frequently sings himself or listens to other people's songs, and a user who does not have such experience. For this reason, if the selection of the questioned music is left to the discretion of the questioner, unfairness arises among the users who are the answerers. In this regard, for example, in goofles and bowling, a handicap is given according to the experience, thereby aiming at fairness for those who participate in the game.

  In this way, in the conventional karaoke performance terminal, when playing a game related to music, fairness among users who are answerers is not considered, and if the questions are biased, the game is sufficiently interesting In some cases, I could not taste it. Such a problem is also true in a simultaneous performance music hitting game or the like in which a plurality of music pieces are played at the same time and the respective music titles are assigned.

  The present invention has been proposed in view of the above-described circumstances, and when playing a game related to music played at a karaoke performance terminal, the game is sufficiently interesting by ensuring fairness among users who are solvers. It is an object to provide a karaoke system that can be enjoyed in the future.

The karaoke system provided with the game function of the present invention has the following features in order to solve the above-described problems.
That is, the karaoke system provided with the game function of the present invention has a game function capable of executing a game related to music played on the karaoke performance terminal among a plurality of users who have logged in to any karaoke performance terminal. It is provided. This karaoke system includes a user ID acquisition unit, a performance frequency management unit for each musical piece, and a question selection unit.

  The user ID acquisition means acquires the user ID of the user who has logged in to any karaoke performance terminal. Each time the performance log management means for each song logs in to the system at any karaoke performance terminal, the performance frequency of the music played until the user logs out is recorded for each user who is currently logged in to the system. It manages by linking to the user ID. The tune selection means obtains the performance frequency of the music managed by the performance frequency management means for each music based on the user IDs of all the users who have logged in the system at a karaoke performance terminal that executes a game related to the performance music. At the same time, with respect to the music acquired in common to all users, the music in which the relative difference between the users in the performance frequency of the music satisfies a predetermined standard is selected and selected as the question music .

  Moreover, it is preferable that the question song selection means can change and set a reference regarding a relative difference between users according to the set number of question songs.

Here, the relative difference between users in the performance frequency of music relates to the difference between the maximum value and the minimum value of the performance frequency of music sung or viewed by each user. In addition, when a music piece selected by linking to its own user ID is played, it is considered that the user has “sung”, and a music piece that is not selected by linking to his / her user ID is played. If this is done, it is considered that the user has watched.
The relative difference satisfies a predetermined standard when all users are singing or watching a song to be tested, and in addition to this, a standard regarding performance frequency (for example, The difference between the maximum value and the minimum value of the performance frequency is a predetermined value (for example, 5 times) or less.

  In the karaoke system provided with the game function of the present invention, the performance frequency of music is recorded and managed by the performance frequency management means for each music every time each user logs in to any karaoke performance terminal. That is, when each user logs in to an arbitrary karaoke performance terminal, the performance frequency is cumulatively recorded and managed for the songs sung or viewed before logging out from the karaoke performance terminal. For example, when a game related to a performance music such as an intro quiz is executed, the performance frequency of the music is acquired for all users who have logged in the system by the question selection means, which is common to all users. For the music acquired in this way, a music whose relative difference between users in the performance frequency of the music satisfies a predetermined standard is selected as the question music.

  As described above, in the karaoke system having the game function of the present invention, a song that is highly likely to be known by all users participating in the game is selected as the question song. Fairness can be achieved.

Hereinafter, an embodiment of a karaoke system having a game function of the present invention will be described with reference to the drawings.
The karaoke system according to the embodiment of the present invention has a function capable of executing a game related to music played on the karaoke performance terminal among a plurality of users who have logged in to any karaoke performance terminal.

In addition to acquiring the frequency, for the music acquired in common to all users, the music whose relative difference between users in the performance frequency of the music satisfies a predetermined standard is extracted, and the title music It consists of a program to select as.

  Specifically, when the user logs in to the system, the function of the question song selection means 51 accesses the performance frequency management database 25 for each song, and the music for each user based on the user ID of the user who logged in the system. Get the playing frequency. The performance frequency of the acquired music is stored in the RAM 45 as a management table for selecting the question music.

With reference to FIG. 3 and FIG. 6, the management table for selecting the question song will be described. FIG. 3 is an explanatory diagram of the question song selection management table according to the first embodiment, and FIG. 6 is an explanatory diagram of the question song selection management table according to the second embodiment.
For example, as shown in FIGS. 3 and 6, the question song selection management table has a configuration in which the performance frequency of songs sung or viewed in the past can be specified for every user who logs in the system. Yes. Note that the process of obtaining the musical performance by the function of the question selection means 51 may be performed when the user logs into the karaoke performance terminal 13 or the intro quiz is executed at the karaoke performance terminal 13. May be performed when the is instructed.

  In the first embodiment shown in FIG. 3, when each user sings or listens to a song and the performance frequency becomes “1” or more, the flag is attached to the song ID, A management table for selecting the title song is constructed. Further, in the second embodiment shown in FIG. 6, each user sings a song or links the performance frequency of the viewed music to the song ID, thereby configuring the question song selection management table. In addition, you may use the performance frequency performed within the predetermined period as a performance frequency of a music.

When this introductory quiz is executed, the tune selection means 51 selects a tune whose relative difference between users in the performance frequency of the acquired tune satisfies a predetermined criterion as a tune. For example, referring to the management table for selecting a question song, a song for which a flag is set for all users who have logged in the system is extracted, or the difference between the maximum value and the minimum value of the performance frequency is a predetermined value (for example, 5 Times) Extract the following songs and select them as questions. In addition, with respect to the performance frequency of each music piece, a music piece whose deviation from the median value is equal to or less than a predetermined value may be selected as a question piece piece.
In this way, music that all users have sung or watched is selected as the title music.

<Problem selection process (first embodiment)>
First, a first embodiment of the question song selection process will be described. FIG. 4 is a flowchart showing the procedure of the question song selection process according to the first embodiment.

As shown in FIG. 4, the question song selection process according to the first embodiment accesses the performance frequency management database 25 for each music piece, and for each music piece based on the user ID of the user who logged in the system. The performance frequency is acquired (S1). And the performance frequency of the acquired music is stored in RAM45 as a management table for question selection music selection (S2).
Subsequently, when introductory quiz execution is instructed (S3), a song whose relative difference between users in the performance frequency of the obtained song satisfies a predetermined standard is extracted and selected as a question song. (S4).

  As a specific example, the management table for selecting the question song shown in FIG. 3 is prepared, and flags are set for all users who have logged in the system as a predetermined standard regarding relative differences between users. If the condition is that the song ID is “*** 2”, “*** 4”, and “*** 7”, three songs are selected as questions.

  The selected questions are presented in order according to a predetermined standard. The predetermined reference regarding the order of questions may be any of the release date of the music, the latest date of singing or watching, the order of 50 notes, or random.

<Question song selection process (second embodiment)>
Next, a second embodiment of the question song selection process will be described.
In the first embodiment described above, a music piece in which the relative difference between users in the performance frequency of the obtained music piece satisfies a predetermined standard is selected as a question piece piece. In this case, it is only necessary to be able to select a sufficient number of questions to play the game, but depending on the setting of the standard regarding relative differences between users, select a sufficient number of questions to be played. The case where it is not possible is also assumed. On the other hand, depending on the setting of the criterion regarding the relative difference between users, there may be a case where the number of extracted question songs is too large and the same question song is obtained every time depending on the criteria of the question order.

  Therefore, in the question song selection process according to the second embodiment, it is possible to change and set the reference regarding the relative difference between users according to the set number of question songs. FIG. 5 is a flowchart showing the procedure of the question song selection process according to the second embodiment.

  As shown in FIG. 5, the question song selection process according to the second embodiment accesses the performance frequency management database 25 according to music and stores the music for each user based on the user ID of the user who has logged in the system. The performance frequency is acquired (S11). And the performance frequency of the acquired music is stored in RAM45 as a management table for question selection music selection (S12).

When introductory quiz execution is instructed (S13), music is extracted based on default criteria (S14), and it is confirmed whether or not a predetermined number (for example, 3 or more) of music has been extracted. (S15). Here, when a predetermined number (for example, three or more songs) of music cannot be extracted, the standard regarding the relative difference between users is changed (S16), and the music is extracted based on the new standard. (S17). Then, until a predetermined number (for example, three or more songs) of music can be extracted, the music regarding the relative difference between users is changed and the music is extracted (S15 to S17).
Here, when a predetermined number (for example, three or more songs) of music pieces can be extracted, the extracted music pieces are selected as question songs (S18).

  With reference to FIG. 6, the change of the reference | standard regarding the relative difference between users is demonstrated. For example, the number of questions is set to 3 or more, and the default standard for relative differences between users is a song sung or watched by all users who have logged in to the system, and the maximum performance frequency. Suppose that the standard that the difference between the value and the minimum value is 5 times or less is set. In this case, in the example illustrated in FIG. 6, only the music having the music ID “*** 4” is extracted, and it is not possible to extract three or more music.

Therefore, as a new standard, a standard is set such that the difference between the maximum value and the minimum value of the performance frequency is 10 times or less for a song sung or viewed by all users who have logged in the system. In this case, in the example shown in FIG. 6, two songs having the song IDs “*** 4” and “*** 7” are extracted, and three or more songs cannot be extracted.
Therefore, as a new criterion, a criterion is set such that the difference between the maximum value and the minimum value of the performance frequency is 15 times or less for a song sung or viewed by all users who have logged in the system. In this case, in the example shown in FIG. 6, three songs with the song IDs “*** 2”, “*** 4”, and “*** 7” are extracted, and the standard regarding the number of questions to be asked (3 or more songs) are satisfied, so these 3 songs are selected as questions.

  In the above example, the standard is gradually relaxed and a predetermined number of questions are selected. However, if there are too many extracted songs, the criteria may be tightened to narrow down the number of questions. . Specifically, for example, as a default standard, a standard is that a song sung or watched by all users who have logged in to the system, and the difference between the maximum value and the minimum value of the performance frequency is 5 times or less. If there are too many extracted questions, the difference between the maximum value and the minimum value of the performance frequency is 4 or less. If there are too many tunes even if a new standard is adopted, the difference between the maximum value and the minimum value of the performance frequency is 3 times or less, 2 times or less, 1 time or less, and so on. It is sufficient to change the standard so that it becomes stricter.

  The configuration may be such that the setting of the number of questions is changed based on an instruction from a user who has logged in the system. Specifically, for example, by performing touch input on the output screen of the remote input / output terminal 32, it is possible to instruct to change the number of questions to be set.

<Intro quiz>
An intro quiz is performed using the selected questions extracted and selected by the above-described procedure. In the present embodiment, any aspect of the intro quiz may be used. For example, when the user touches an “intro contact quiz” button displayed on the input / output display unit of the remote input / output terminal 32, the intro contact quiz is executed. Then, the intro part of the selected question piece is played in a predetermined order.

Regarding the determination of the correct answer, information related to the question song (correct answer information) is displayed on the input / output display unit of the remote input / output terminal 32, and it is determined whether or not the user designated as the determiner is the correct answer. It can be. Moreover, it is good also as a structure which an answerer inputs answer information using the touch input of the remote input / output terminal 32, and determines whether it is a correct answer using the determination function with which the karaoke performance terminal 13 is provided.
The intro quiz is described in detail in, for example, Japanese Patent Laid-Open Nos. 10-78785 and 2002-41071.
