TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technique for recommending a requested song to a karaoke user in a communication karaoke system.
[0002]
[Prior art]
In general, karaoke is assumed to be a usage form in which several users turn to singers or listeners to each other, and karaoke performances and singing continue continuously. Rather, it can be said that it is used sufficiently only in such a situation. However, such efficient use is not always achieved. In a group where the number of people is small or there are few people who are not very active, when one karaoke performance is completed, it is difficult to reserve the next performance, and sometimes there is a blank time for the performance. It is very convenient for the user to recommend a suitable song in such a situation, because the user can save time and effort in searching for the song and can use time effectively. From such a viewpoint, the present applicant has disclosed the technology described in Patent Document 1 below.
[0003]
With this technology, every time a music piece is played, the music piece that has been played most frequently after that music piece is extracted based on the statistics of the usage history of users (customers) nationwide, and the next performance piece is played. It is recommended as a candidate. In addition, a technique for making a recommendation in consideration of the attribute information of the customer or the music is also disclosed.

[Problems to be solved by the invention]
However, since the number of customers varies greatly depending on the area where the karaoke store is located, it is not always possible to recommend an appropriate tune by the above-described technique. In addition, the communication karaoke system needs to recognize the identification information of the user in order to take into account the attribute information of the user. For this purpose, an individual device such as a personal remote controller or an input operation of an ID or the like by a user is required, but in reality, it is costly or troublesome, and it is easy for the user to accept the operation easily. .
[0006]
Therefore, the present applicants do not need the identification information of the user and recommend the appropriate music reflecting the locality (customer segment) of the karaoke store to the user based on the statistics of the use history at the store. To select recommended songs. On the other hand, there is a situation that most of the songs frequently played in the store are so-called regular customers. Regular patrons are not always preferred by people other than regular patrons, and are not suitable as recommended songs. Therefore, from the songs selected based on the usage history statistics at the store as described above, songs that are frequently played in the usage history statistics of users (customers) nationwide are excluded from the music selection, and the recommended songs are selected. Thought. This is because it is thought that the regional characteristics are not reflected in the 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 a requested music suitable for a user of a karaoke store without requiring user identification information. It is in.
According to the method of the present invention, in a communication karaoke system in which a karaoke host device and a plurality of karaoke performance devices are connected via a communication network, the karaoke host device collects performance history information in each karaoke performance device. A karaoke performance device creates a ranking list in which the music performed by all the karaoke performance devices is totaled based on the performance frequency and distributes the karaoke performance device to each karaoke performance device. Based on the information of the performance history in the performance device, identification information of a predetermined number of music pieces played after the music piece A is extracted, and identification information of a predetermined number of high-order music pieces in the ranking list is excluded from the extracted information. Then, other music identification information is tabulated based on the number of times of performance to create a recommended music list, and presented to the user as appropriate.
[0008]
In this method, preferably, when the user performs an operation of selecting a music piece from the presented recommended music list, a performance reservation command including identification information of the music piece is transferred to the karaoke performance apparatus.
Preferably, when creating a recommended music list, a recommended music list is created by excluding, from the extracted information, identification information of music played within the immediately preceding predetermined time in the karaoke playing apparatus.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
=== Example of system configuration ===
In a 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 a public telephone line 2 directly or via a private branch exchange, and external karaoke apparatuses connected to the public telephone line 2 are connected. It is configured to be able to communicate with the karaoke host device 3 (see FIG. 1).
[0010]
The karaoke host device 3 is a computer operated by a karaoke company. Data communication is performed via the public telephone line 2 with a number of karaoke performance devices 1 installed in various places in the jurisdiction area. The karaoke host device 3 stores and manages a large number of karaoke data, and distributes the karaoke data when the karaoke performance device 1 is newly installed or when new karaoke music data is additionally registered. In addition, information on the use status of the karaoke performance device 1 is collected from each karaoke performance device 1 at an appropriate opportunity and managed.
In particular, information on the played music (playing history) is regularly collected, and the number of performances of each music within a jurisdiction area (nationwide) within a certain period (one month in this embodiment) is counted. It is managed as a nationwide list of performance frequencies. The karaoke host device 3 also distributes this national ranking list to each karaoke performance device 1 under its jurisdiction at an appropriate occasion.
[0011]
The karaoke performance apparatus 1 is a computer applied device equivalent to a personal computer. FIG. 2 shows a hardware-based configuration example of the karaoke performance apparatus. The central processing unit 11 is a computer main body including a CPU, a RAM, and a ROM. A hard disk device 12 as a large-capacity external storage, an optical disk device 13 for reproducing a CD-ROM or a DVD-ROM, a communication control device 14 for communicating with the karaoke host device 3 via the public telephone line 2, and an input from a user. A user interface device 15 for exchanging responses with the user, a music generation device 16 for generating an audio signal of accompaniment music based on MIDI music performance data, and an audio signal from an accompaniment music or a microphone. An audio device 17 that amplifies and emits 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 provided with short-range wireless communication means (IrDA transceiver, infrared LED, infrared light receiving element). ing.
[0012]
=== Karaoke data basic processing ===
Upon receiving a music request via the user interface device 15, the central processing unit 11 of the karaoke performance device 1 creates a performance reservation queue in an appropriate storage unit based on the reserved music information included in the request. It manages the order of karaoke songs. The music reservation information includes music identification information (music number) of the desired music. When the performance reservation information is input, the central processing unit 11 confirms that the music number in the music reservation information is the number of a playable music registered in the karaoke database, and registers the music number in a queue. .
[0013]
The central processing unit 11 extracts music numbers from the queue in the order of registration, and extracts and processes karaoke data of the corresponding music from a karaoke database constructed in the hard disk device 12. The karaoke data is composed of music performance data, which is the origin of accompaniment music represented by MIDI data or ADPCM data, using song numbers as keys, lyrics subtitle data for displaying lyrics subtitles synchronized with the accompaniment music, and accompaniment music. Is a data group to which a video selection descriptor or the like that directly or indirectly specifies a video program to be displayed during the output period is associated.
[0014]
=== Recommended song selection method ===
The karaoke performance apparatus 1 according to the present embodiment presents some recommended songs to the user when the reservation of the performance by the user is interrupted. For this purpose, the user selects a song suitable for playing next to the song last selected.
[0015]
The karaoke performance apparatus 1 accumulates the music numbers of the music pieces that have been subjected to the performance processing in that order and manages the music numbers as the above-mentioned performance history. The central processing unit 11 starts the recommended music selection process when the preparation for playing 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 A is searched from the data of the performance history, and information of five music pieces subsequently played is extracted. This is referred to as “the next five songs” of A. For example, in the example of FIG. 3, the “next five songs” related to A played first are five songs of G, E, N, G, and E. The “next five songs” are extracted from the performance history data to be subjected to the recommended song selection process, with respect to data on all songs A. In the example shown in the figure, B, E, M, G and N are the “next five songs” related to A played for the second time. Similarly, the “next 5 songs” related to A played the third time are U, T, C, E, and U. In this way, the “next 5 songs” for all A are extracted. Each song is totaled in order of the number of times played. This is referred to as a karaoke store ranking list (store ranking list).
[0017]
Further, from the shop ranking list, songs corresponding to the top 100 songs in the national ranking list are excluded, and the resulting top songs (for example, three songs) are set as recommended songs.
Of course, the same result can be obtained by extracting the “next 5 songs” related to A, immediately excluding the top 100 songs in the nationwide ranking list, summing up, and immediately deriving a recommended song list.
[0018]
According to this method, it is possible to select, as a recommended song, a song that does not have a sense of incongruity with the song selected last by the user and that does not interrupt the atmosphere of the place. Moreover, it is possible to select a song that is unexpected and different from a song that is popular nationwide while reflecting the customer segment of the store.
[0019]
Furthermore, it is also possible to exclude from the list music pieces played within the immediately preceding predetermined time. 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 on the display 18 together with the song names and song numbers at appropriate occasions, such as when the performance of the selected songs has ended. When the user selects one song from the songs displayed on the display 18 and inputs the song using the user interface device 15, the identification information of the song is registered in a performance reservation queue.
[0021]
Note that the recommended music can be displayed on a display unit of the interface device 15 or the like. In particular, it is also possible to display the information on the touch panel display of the search-type karaoke remote control device. In this case, it is also possible to wirelessly transfer the performance reservation command to the karaoke performance device when the user touches the selected music on the touch panel.
[0022]
=== Other Embodiments ===
In the above-described embodiment, a method of extracting five pieces of music continuously performed after the piece of music A as “the next five pieces of music” is adopted. This number is variable. It has been statistically confirmed that, for a music piece with a lower playing frequency, a larger recommended value can extract a more suitable recommended music piece.
[0023]
Although the top 100 songs in the whole country are excluded from the store ranking list, this numerical value is also variable. Although it depends on the period of accumulating the performance history information and the total number of songs, it has been statistically confirmed that even if the top 150 songs nationwide are excluded, a suitable recommended song can be selected.
[0024]
【The invention's effect】
According to the method of the present invention, it is possible to select, as a recommended song, a song that does not have a sense of incongruity with the song that was last selected by the user and does not interrupt the atmosphere of the place. In addition, it is possible to select a song that is unexpectedly different from a song that is popular nationwide while reflecting the customer segment of the store. Even those who have few opportunities to use karaoke can enjoy it easily and without hassle. In addition, even for those who frequently use the music, an opportunity to sing a surprising song different from the song usually sung is created, and a new enjoyment can be pioneered. Therefore, the effect of expanding the karaoke users can be expected.
