The present invention relates to a technique for recommending requested music to a karaoke user in a communication karaoke system.
[0002]
[Prior art]
In general, karaoke is supposed to be used in such a way that karaoke performance and singing continue continuously while several users are singing and listening to each other. Rather, it can be said that it is fully used only in such a usage situation. However, such efficient use is not always made. In a group where the number of people is small or there are not very active people, when a karaoke performance is over, the next performance reservation is not easily made, and there may be frequent blank times for the performance. Providing an appropriate song in such a situation is very convenient for the user because it saves time and effort to search for the song. From such a viewpoint, the present applicant has disclosed the technique described in Patent Document 1 below.
[0003]
With this technology, every time a song is played, based on the statistics of user (customer) usage history nationwide, the next played song is extracted and the next performance is extracted. It is recommended as a candidate. Furthermore, a technique for recommending in consideration of attribute information of the customer and the music is also disclosed.

[Problems to be solved by the invention]
However, since the customer base varies greatly depending on the area where the karaoke store is located, it is not always possible to recommend an appropriate piece of music even with the above technique. In addition, in order to take into account user attribute information, it is necessary for the communication karaoke system to recognize the user identification information. This requires individual devices such as a personal remote controller or a user to input an ID or the like. However, in reality, it is costly or cumbersome, and it is easy for the user to easily accept the operation. .
[0006]
Therefore, the present applicants based on statistics of usage history in the store in order to recommend to the user appropriate music that reflects the locality (customer class) of the karaoke store without requiring the user's identification information. I decided to select a recommended song. On the other hand, there are circumstances that most of the music frequently played in the store is so-called regular customers. The regular customer's eighteenth is not necessarily preferred by people other than regular customers, and it cannot be said to be suitable as a recommended song. Therefore, from the music selected based on the usage history statistics in the store as described above, the music that is frequently played in the usage history statistics of nationwide users (customers) is excluded to make the recommended music. Thought. This is because it is considered that regional characteristics are not reflected in music that is frequently played nationwide.
[0007]
[Means for Solving the Problems]
As described above, an object of the present invention is to provide a recommended music selection method in a communication karaoke system that can recommend requested music suitable for a user of a karaoke store without requiring user identification information. There is.
The method according to the present invention is a communication karaoke system in which a karaoke host device and a large number of karaoke performance devices are coupled via a communication network. The karaoke host device collects performance history information in each karaoke performance device. Then, a ranking list in which performance songs in all karaoke performance devices are tabulated based on the performance frequency is created and distributed to each karaoke performance device. When the karaoke performance device makes a performance reservation for a song A, the karaoke performance device Based on the performance history information in the performance device, the identification information of a predetermined number of songs performed subsequent to the music A is extracted, and the identification information of the predetermined number of high-order songs in the ranking list is excluded from the extracted information. Then, other music identification information is tabulated based on the number of performances, a recommended music list is created, and presented to the user as appropriate.
[0008]
Preferably, in this method, when the user performs an operation of selecting a song from the recommended song list presented, a performance reservation command including identification information of the song is transferred to the karaoke performance device.
Desirably, when the recommended music list is created, the recommended music list is created by excluding the identification information of the music played within the predetermined time immediately before in the karaoke performance device from the extracted information.

DETAILED DESCRIPTION OF THE INVENTION
=== System configuration example ===
In the communication karaoke system according to one embodiment of the present invention, a large number of karaoke performance apparatuses 1 scattered in various places are connected to the public telephone line 2 directly or via a private branch exchange, and are connected to the public telephone line 2. It is comprised so that communication with the karaoke host apparatus 3 is possible (refer FIG. 1).
[0010]
The karaoke host device 3 is a computer operated by a karaoke company. Data communication is performed with a large number of karaoke performance apparatuses 1 installed in various places in the jurisdiction area via the public telephone line 2. A lot of karaoke data is stored and managed in the karaoke host device 3, and karaoke data is distributed when the karaoke performance device 1 is newly installed, or when new karaoke data is additionally registered. Moreover, the information regarding the usage status of the karaoke performance device 1 is collected and managed from each karaoke performance device 1 at appropriate occasions.
In particular, information on the music played (performance history) is regularly collected and the number of performances within a certain period (one month in this embodiment) of each music in the jurisdiction area (nationwide) is tabulated. It is managed as a national ranking list of performance frequencies. The karaoke host device 3 also distributes this nationwide ranking list to each karaoke performance device 1 having jurisdiction over appropriate occasions.
[0011]
The karaoke performance device 1 is a computer application device equivalent to a personal computer. FIG. 2 shows a hardware-based configuration example of the karaoke performance device. The central processing unit 11 is a computer main body including a CPU, a RAM, and a ROM. Hard disk device 12 as a large-capacity external storage, optical disk device 13 that reproduces a CD-ROM or DVD-ROM, communication control device 14 that communicates with karaoke host device 3 via public telephone line 2, and input from a user A user interface device 15 for exchanging a response to the user, a music generation device 16 for generating an acoustic signal of accompaniment music based on MIDI music performance data, and an acoustic signal from the accompaniment music or microphone. An audio device 17 that amplifies and produces sound from a speaker, a display 18 using a CRT, LCD, PDP, or the like, and a video processing device 19 that processes video data to be displayed on the display 18 are provided.
The user interface device 15 includes an operation panel (keyboard and display) of the device main body and a karaoke remote control device equipped with short-range wireless communication means (IrDA transceiver, infrared LED, infrared light receiving element). ing.
[0012]
=== Basic processing of karaoke data ===
When the central processing unit 11 of the karaoke performance apparatus 1 receives the request for music via the user interface device 15, it creates a performance reservation queue in an appropriate storage unit based on the reserved music information included in the request. , Manages the performance order of karaoke songs. The performance reservation information includes music identification information (music number) of the desired music. When the central processing unit 11 receives the performance reservation information, the central processing unit 11 confirms that the music number in the music processing number is a number of music that can be played in the karaoke database, and registers the music number in the queue. .
[0013]
The central processing unit 11 extracts the music numbers from the queue in the order of registration, extracts the karaoke data of the corresponding music from the karaoke database built in the hard disk device 12, and processes the data. Karaoke data includes music performance data that is the origin of accompaniment music expressed in MIDI data, ADPCM data, etc., using song numbers as keys, lyrics subtitle data for displaying lyrics subtitles synchronized with accompaniment music, and accompaniment music Is a data group associated with video selection descriptors that directly or indirectly specify video programs to be displayed during the output period.
[0014]
=== Recommended music selection method ===
The karaoke performance apparatus 1 according to the present embodiment presents some recommended music pieces to the user when the performance reservation by the user is interrupted. Therefore, the music suitable for performing after the music last selected by the user is selected.
[0015]
In the karaoke performance apparatus 1, the music numbers of music pieces that have been subjected to performance processing are stored in that order and managed as the above-described performance history. The central processing unit 11 starts the recommended music selection process when preparation for performance of a certain music A is completed and the music to be played next is not registered in the queue. FIG. 3 is a diagram showing the concept of the processing.
[0016]
First, data relating to the music piece A is searched from the performance history data, and information on five music pieces subsequently played is extracted. This is A's “next 5 songs”. For example, in the example of FIG. 3, the “next five songs” related to A played first are five songs G, E, N, G, and E. “Next 5 songs” are extracted from the data related to all the songs A among the performance history data to be subjected to the recommended song selection process. In the example shown in the figure, the “next five songs” related to A performed for the second time are B, E, M, G, and N. Similarly, the “next five songs” related to A performed for the third time are U, T, C, E, and U. In this way, the “next 5 songs” for all A are extracted. Each music is counted in the order of the number of performances. This is a ranking list (store ranking list) of this karaoke store.
[0017]
Furthermore, the music corresponding to the top 100 songs in the national ranking list is excluded from the store ranking list, and the resulting top songs (for example, 3 songs) are set as recommended songs.
Of course, the same result can be obtained by extracting and summing up the songs corresponding to the top 100 songs in the national ranking list immediately after extracting the “next 5 songs” for A, and immediately deriving a list of recommended songs.
[0018]
According to this method, it is possible to select a music piece that has no sense of incongruity with the music piece selected by the user at the end and that does not interrupt the atmosphere of the place as the recommended music piece. Moreover, it is possible to select an unexpected musical piece that is different from a popular national song while reflecting the customer base of the store.
[0019]
Furthermore, the music played within the predetermined time immediately before can be excluded from this list. According to this method, it is possible to prevent the same music from being selected as a recommended music many times in a short time.
[0020]
Some recommended songs selected as described above are displayed in a list on the display 18 together with the song name and the song number at an appropriate occasion such as when the selected song has been played. When the user selects one song from the songs displayed on the display 18 and inputs it using the user interface device 15, the identification information of the song is registered in the performance reservation queue.
[0021]
Note that the recommended music can be displayed on the display unit of the interface device 15 or the like. In particular, it is also possible to display on a touch panel display unit of a search-type karaoke remote control device. In this case, it is also possible to wirelessly transfer the performance reservation command to the karaoke performance apparatus when the music selected on the touch panel is touched.
[0022]
=== Other Embodiments ===
In the above-described embodiment, the method of extracting the five songs that were performed after the song A as the “next five songs” was adopted. This number is variable. Statistically, it has been confirmed that a music piece with a lower performance frequency can extract a recommended music piece with a higher value.
[0023]
In addition, music from the store ranking list to the top 100 nationwide is excluded, but this numerical value is also variable. Although it depends on the period for accumulating performance history information and the total number of songs, it has been confirmed from statistics that appropriate recommended songs can be selected even if the top 150 songs nationwide are excluded.
[0024]
【The invention's effect】
According to the method of the present invention, it is possible to select a music piece that has no sense of incongruity with the music piece selected by the user at the end and that does not interrupt the atmosphere of the place as the recommended music piece. Moreover, it is possible to select an unexpected musical piece that is different from a popular national song while reflecting the customer base of the store. Even people with few opportunities to use karaoke can enjoy it without hesitation and effort. Also, for those who use it frequently, the opportunity to sing unexpected music that is different from the music that they normally sing is created, and new enjoyment can be cultivated. Therefore, the effect that a karaoke user layer expands can be expected.
