Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a karaoke system, and more particularly, to a karaoke automatic music selection performance system that makes it unnecessary for a user to explicitly input a music number by using user attribute information or the like.
[0002]
[Prior art]
In a karaoke system, performance is usually started by explicitly inputting and selecting a song number. As a method of playing a plurality of songs with a single selection of music, a method of combining a plurality of songs in advance into a single song number, such as a medley, is also used.
[0003]
Japanese Patent Laid-Open No. 5-257487, “Karaoke music selection device using fuzzy reasoning” describes that automatic music selection is performed using fuzzy theory by inputting parameters of a song desired by a user. ing. In this case, if the parameters are the same, the same music may be automatically selected. The automatic music selection apparatus presents candidates on the display, and the user selects and inputs music from the candidates. The user manually switches between automatic music selection and explicit music selection from the user. Further, the input conditions are attributes for the music (music brightness, singer age, singing ability, etc.). Various parameters are recorded statically.
[0004]
[Problems to be solved by the invention]
In the conventional karaoke system, when the user uses the song number explicitly to start the performance, the performance is not started unless the user searches for the song in a booklet or the like and inputs it. .
[0005]
On the other hand, in the “karaoke music selection device using fuzzy inference” described in Japanese Patent Application Laid-Open No. 5-257487, the user inputs the conditions of the song attributes (the brightness of the song, the singer's age, the singing ability, etc.). It is possible to perform automatic music selection. However, if the parameters are the same, the same music may be automatically selected. Also, items that are close to the attributes of the song (sound intensity, singer's age, singing ability, etc.) are listed, and the user selects and inputs music from that list, so input is required again before the performance. It is a problem.
[0006]
In addition, since the input condition is an attribute for the song (sound intensity, singer age, singing ability, etc.), in the case of a plurality of users, the condition of each individual is not reflected. For example, the use in groups with different preferences, such as multiple men and women, is a problem that is not considered in automatic music selection. In addition, since various parameters related to songs use statically recorded parameters, it is a problem that cannot cope with trends such as changes in fashion and popularity.
[0007]
An object of this invention is to provide the karaoke automatic music selection performance system which solved the above problems.
[0008]
[Means for Solving the Problems]
The present invention is a karaoke automatic song selection / playing system that includes a song database and automatically selects songs and performs automatically, and the song number stored in the song database and user attribute information that recommends the song , A song-related information database in which additional information including automatic music selection permission information indicating permission / non-permission of automatic music selection of the music is stored in association with each other, and includes age, sex, and number of users for each user An input device for inputting user information and a desired condition regarding music selection, and a user attribute corresponding to use by one person or a group is estimated based on the input user information, and the estimated user attribute And additional information in the music related information database based on the desired condition, and automatically select one or more songs from among the songs that have many matching items and whose automatic music selection permission information is permitted. A control device for playing, a request information database for storing song information selected by the user, and the contents of the request information database are transmitted to the center device through a line, and based on this, the center device automatically selects the song related information center database. And a communication device that receives a result of updating the additional information including the music selection permission information from the center device and updates the additional information in the music related information database.
Further, the automatic karaoke music selection / playing system of the present invention has a storage device for storing information on the music that has been automatically played once, and the control device does not perform the performance when the music that has been played once is automatically selected. It is characterized by automatic music selection.
Furthermore, in the automatic karaoke music selection / playing system of the present invention, when a reservation is made by an input in which a song number is explicitly specified during the automatic music selection performance, the reservation is made after the performance by the automatic music selection is completed. This is characterized in that the selected music is prioritized.
[0009]
According to the present invention, it is possible to automatically perform an automatic music selection performance according to the user without the user explicitly inputting the music number. In addition, in the present invention , including user attribute information recommended in the additional information of the music related information database, a group attribute derived from the attribute of one or more users and the number of people information is also selected and automatically selected. By starting the performance, automatic music selection performance is possible even when used by multiple people. In addition, when there is a user request, it is possible to perform with priority over performance by automatic music selection.
[0010]
Further, in the present invention, in order to dynamically reflect the latest song information and the like, the request information database data of the automatic karaoke automatic tuning performance system is transmitted to the center device, and the song related information center database of the center device is transmitted. Update the contents. Then, the contents of the song related information database of the automatic karaoke music selection performance system are updated through the line based on the contents of the song related information center database. In this way, the latest song database and additional information can be dynamically reflected.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration example of an entire karaoke automatic music selection performance system according to the present invention. As shown in the figure, a plurality of karaoke automatic music selection performance systems 100 are generally connected to a center device 200.
[0012]
The karaoke automatic music selection performance system 100 includes an input device 101 for a user to input automatic music selection conditions and requests, automatic music selection ON / OFF, automatic music selection ON / OFF flags, input conditions, requested music, automatic music selection list, etc. A storage device 102 that temporarily stores information, a calculation control device (CPU) 103 that executes user attribute detection and automatic music selection processing together with overall control, and a song number stored in a song database (song DB) 106 A song-related information database ( song-related information DB ) 104 in which additional information is stored in association with the song, a karaoke system 105 for sequentially reproducing the requested or automatically selected song, and song data are stored. Song DB 106, microphone input device 108 used when a user sings, audio output device for outputting sound Device 107, display 109 for outputting information such as lyrics and video as video, request information database (request information DB) 110 for recording the history of music information explicitly input by the user, communication for communicating with center device 200 The device 111 is configured.
[0013]
Further, the center device 200 includes a communication device 201 that communicates with each karaoke automatic music selection system 100, a song related information center DB 202 that stores additional information associated with the song number and the song, and an automatic karaoke music selection system 100. Based on the requested song information received from the calculation control device 203 that updates the contents of the song related information center DB 202.
[0014]
The automatic karaoke music selection / playing performance system 100 performs automatic music selection and starts automatic performance under the control of the arithmetic and control unit 103 by inputting only simple conditions without the user explicitly inputting the music number. Realize that. For example, when the user starts using, the user inputs the conditions of “user age / sex / number information”, “songs of years ago”, “male / female singer” and “automatic music selection start” from the input device 101. As a result, it is not necessary for each person to select and input a song number from a booklet or the like as in the prior art. It also solves the problem that it takes time to actually select and play a song after entering the store. The automatic music selection performance enables the performance of songs that can be sung but do not know the title. Further, “recommended user attribute” is described in the additional information of the song related information DB 104, and the arithmetic and control unit 103 estimates the user attribute from the input information of a plurality of users, and the song related information. By collating the DB 104, it is possible to automatically select a song suitable for a plurality of users and perform it.
[0015]
The user inputs desired conditions using the input device 101, and turns on the function of the automatic music selection system. FIG. 2 shows an example of an input screen for automatic music selection conditions. On the automatic music selection condition input screen, using the input device 101 such as a touch panel, a content 20 related to “user age / sex / number” and a content 21 related to “song genre” and “popular time” Enter simple song selection conditions.
[0016]
Based on the input conditions, the arithmetic control device 103 performs a predetermined calculation, and derives (estimates) the attribute of the user corresponding to the use by one person or a group. For example, a group of 15 to 20-year-old females is a “high school girl group”, and a group of 20 to 40-year-olds is a “company employee group”. User attributes are estimated such as “family group” for men and women, “couple” for men and women of the same age, and “compa group” for men and women of the same age. This can be easily realized by means such as indexing a table. Then, the arithmetic and control unit 103 performs automatic music selection with reference to the music related information DB 104 based on the input desired conditions and the estimated user attributes.
[0017]
FIG. 3 shows a description example of the song related information DB 104. In the song-related information DB 104, as information related to the song number 30, a genre 31, a fashion season 32, a gender 33, automatic song selection permission information 34, and user attribute information 35 are registered. In addition, in order to reduce the phenomenon in which a song that the user does not know is played, a song with a lot of statistical requests or a song with a large number of CDs / records sold is set as “permitted” in the automatic song selection permission information 34. , Prevent songs that have been set to “not allowed” from being automatically selected.
[0018]
Automatic music selection is realized by performing a predetermined calculation using the item selected by the user input conditions 20 and 21, the item registered and registered in the music related information DB 104, and the estimated user attribute information. To do. For example, when there is an item that matches the condition, the calculation may be performed by adding the points of the song and selecting a song at random from the pre-designated upper songs having many points. By using random music selection, different music selection is possible even under the same input conditions. If a song that has been automatically selected and played once is selected again, the song is ignored and the song is selected again.
[0019]
4 and 5 show processing flowcharts of the first embodiment. This is a process flowchart for executing the selection of music every time a piece of music is played.
[0020]
FIG. 4 shows a processing flowchart when inputting automatic music selection conditions. The user inputs automatic music selection conditions using the input device 101 (step 41). The input automatic music selection conditions are stored in the storage device 102 via the arithmetic control device 103. Next, the arithmetic and control unit 103 derives (estimates) and detects the user attribute from the input condition, stores it in the storage device 102 (step 42), and turns on the automatic music selection flag prepared in the storage device 102 (step 42). 43). The automatic music selection flag can be manually turned on / off by the input device 101. When a user wishes to make a reservation by explicitly specifying a music number during performance by automatic music selection, the user forcibly turns off the automatic music selection flag and explicitly inputs the music number. The reserved music number is stored in the storage device 102 via the arithmetic control device 103.
[0021]
FIG. 5 shows a process flowchart during performance. This process flow is repeated each time a piece of music is played. When the performance of one music piece is finished, the arithmetic and control unit 103 determines whether or not the automatic music selection flag of the storage device 102 is ON (step 51). If the automatic music selection flag is ON, it is determined whether or not there is a reserved music in the storage device 102. If there is no explicit music reservation from the user (step 53), automatic music selection based on the input conditions is executed (step 53). In this case, the arithmetic and control unit 103 compares the corresponding items in the song related information DB 104 based on the conditions input by the user and the derived user attributes, and if there is a matching item, the point of the song is added. In addition, the automatic music selection permission information is set as permission, and one music piece is randomly selected from a pre-specified number of upper groups with many points. Then, it is checked whether or not the automatically selected music is already stored in the storage device 102, that is, whether or not the music has already been played (step 54). Redo the song selection. If it is not an overlap performance, the arithmetic and control unit 103 stores the automatically selected music in the storage device 102 and sends it to the karaoke system 105 to start the performance (step 56). Then, when the performance of one song is finished (step 57), the process returns to step 51.
[0022]
On the other hand, when the automatic music selection flag is OFF and there is an explicit music reservation by the user, the arithmetic and control unit 103 selects one of the songs reserved from the storage device 102 (step 58), and the karaoke system Sent to 105. As a result, when a reservation by an input in which a song number is explicitly specified occurs during performance by automatic music selection, the reserved music is preferentially played after the performance by automatic music selection is completed.
[0023]
6 and 7 show processing flowcharts of the second embodiment. This is a process flowchart in which only a predetermined number of songs are selected and sequentially played.
[0024]
FIG. 6 shows a processing flowchart when inputting automatic music selection conditions. The user inputs automatic music selection conditions using the input device 101 (step 61), and the input automatic music selection conditions are stored in the storage device 102 via the arithmetic control device 103. The arithmetic and control unit 103 derives the user attribute from the input condition and stores it in the storage unit 102 (step 62), and then executes automatic music selection (step 63). The automatic music selection process is basically the same as in step 53 above, but here, a plurality of predetermined music pieces are randomly selected from the upper group having many points. The automatic music selection list is stored in the storage device 102 (step 64), and the automatic music selection flag prepared in the storage device 102 is turned on (step 65). If a song that has been played once is included in the automatic song selection list, a song with the next highest point may be added instead of the song.
[0025]
FIG. 7 shows a process flowchart during performance. When the previous performance is finished, the arithmetic and control unit 103 determines whether or not the automatic music selection flag of the storage device 102 is ON (step 71). If the automatic music selection flag is ON, the arithmetic control device 103 explicitly indicates to the storage device 102 from the user. It is determined whether there is a reserved music (step 72). If there is no reserved music, the music is selected from the automatic music selection list in the storage device 102 (step 73). That is, the arithmetic and control unit 103 selects songs one by one from the automatic song selection list stored in the storage device 102, sends them to the karaoke system 105, and causes the karaoke system 105 to play sequentially (step 74). When the previous performance is completed (step 75), the process returns to step 71.
[0026]
On the other hand, when the automatic music selection flag is OFF and the user has an explicit music reservation, the arithmetic and control unit 103 sequentially selects the reserved music from the storage device 102 and sends it to the karaoke system 105. As a result, when multiple songs are automatically selected, the performance of the automatically selected song is temporarily interrupted when the currently playing song is finished at the time of input. Automatic performance can be continued.
[0027]
Depending on the setting of the user, it is possible to perform only the main part of the song as in the medley or to perform automatically only for the first performance.
[0028]
Also, during automatic performance, the user attribute information 35 of the music obtained from the additional information in the music related information DB 104 and the user input conditions 20 and 21 are acquired, and a message is output to the display 109 by the arithmetic and control unit 103. Is also possible. For example, a message such as “This song is suitable for men in their 50s” and a method of singing such as “Let's turn and sing together in the automatic performance mode” are presented.
[0029]
Next, the function of the center apparatus 200 will be described. The music number explicitly requested by the user is stored in the request information DB 110 via the arithmetic control device 103. The communication device 111 accesses the center device 200 and sends the contents of the request information DB 110 as needed. The center apparatus 200 includes a song related information center DB 202 that includes a song related information DB 104. The arithmetic and control unit 203 of the center device 200 first performs additional registration of a song for which the number of requested songs sent is greater than the appropriate reference if it is not registered in the song related information center DB 202, and the corresponding song Is “permitted” in the automatic music selection permission item 34, it is changed to “permitted”. On the other hand, if the requested music is less than the appropriate standard, the automatic music selection permission item 34 of the corresponding music is set to “not permitted”. Then, the center device 200 updates the song related information DB 104 of the karaoke automatic music selection performance system 100 via the communication devices 201 and 111. In this way, it is possible to dynamically reflect user behavior.
[0030]
【The invention's effect】
According to the automatic karaoke music selection performance system of the present invention, the following effects can be obtained.
(1) System-driven elements are also incorporated into the karaoke system that has been operated by the user, so that the user can enjoy even passive elements.
(2) The time from entering the karaoke to the start of performance can be shortened, and even if there is no clear song you want to sing, there is no problem in selecting a song.
