Description

  The present invention relates to a technique for efficiently recommending an appropriate requested song to a predetermined karaoke user in a communication karaoke system.

  In general, users of online karaoke systems use several people as singers or listeners, but it is efficient enough especially when karaoke performance and singing continue without interruption. It can be said that it is being used. However, such efficient use is not always made. For example, in a group where the number of people is small or there are not so many active people, when a karaoke performance is over, the next performance reservation is not easily made, and there may be times when there is a blank time for the performance. In such a situation, recommending an appropriate piece of music can be very convenient for the user because it saves the trouble of searching for a piece of music and can also use time effectively.

  From such a viewpoint, conventionally, a technique for recommending appropriate music to the user has been conceived. For example, in Patent Document 1, each time a certain musical piece is played, based on the statistics of the usage history of users (customers) nationwide, the musical piece that was played next to the musical piece is extracted and played. A technique recommended as a candidate is disclosed. Furthermore, this discloses a technique for recommending appropriate music in consideration of user and music attribute information.

  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, to discriminate the preference of music for each user and recommend appropriate music, as in the above technology, if you follow the preference trend based on attribute information such as gender and age, some appropriate recommendation It is true that personal preferences are not necessarily based on gender or age. Rather, there are many people who have many common items in their favorite music, regardless of gender or age. Therefore, if a user whose preference is approximated is identified instead of user attribute information and a song is recommended with reference to the singing history (performance history of user selection), a more direct and appropriate song can be obtained. Can be recommended efficiently.

  Therefore, the present invention provides a recommended music selection method that can efficiently recommend an appropriate requested music to a predetermined karaoke user by specifying a user whose preference is similar in the online karaoke system and referring to the singing history. The issue is to provide

  In view of the above-mentioned problems, the present inventors collect a singing history for each user, create a ranking list for each user arranged in order of singing frequency, and when any user logs in to the karaoke system, Compares songs in the user's rank list with those in the other's rank list that are equal to or higher than a predetermined rank. If there is a music to be extracted, the above-mentioned problem can be solved by adopting a method of creating a recommended music list based on the extracted music and presenting it appropriately, and conceived the recommended music selection method of the present invention. did.

That is, in the recommended music selection method according to claim 1 of the present invention, in a communication karaoke system in which a karaoke host device and a large number of karaoke performance devices are connected via a communication network, the following (1) to (4) ).
(1) The karaoke host device collects the singing history for each user who has logged into the karaoke system from an arbitrary karaoke performance device, and based on the singing history, the usage is arranged in order of singing frequency for each user. Create a ranking list by person,
(2) When an arbitrary user logs in to the karaoke system from an arbitrary karaoke performance device, the tune lists of the user in the ranking list and the rankings of others are compared with each other.
(3) By comparing the music pieces, if there is a music piece that is common among rank lists of a predetermined ratio or more with respect to another person's rank list having a degree of coincidence of a predetermined number or more, this is extracted and Transferred to a karaoke performance device,
(4) In the said karaoke performance apparatus, the recommended music list based on the said extracted music is created and it shows suitably.

  The recommended music selection method according to claim 2 of the present invention is the recommended music selection method according to claim 1, wherein in (3), the music common to the rank lists of a predetermined ratio or more is all between the rank lists. It is characterized by being a common song.

  According to the recommended music selection method according to claim 1 of the present invention, a predetermined user and others based on a user-ordered list created by arranging in order of singing frequency from the collected singing history for each user. Users who have similar preferences can be identified by comparing songs that are higher than a predetermined rank of a person, and then a rank higher than a predetermined ratio for a rank list of others who have a degree of match of a predetermined number or more of songs If there is a common music between the lists, it is extracted, and a recommended music list is created and presented as appropriate, so that it is possible to efficiently recommend more appropriate and appropriate music.

  Further, according to the recommended music selection method according to claim 2 of the present invention, music that is common among the rank lists of a predetermined ratio or more is music that is common to all the rank lists, that is, the predetermined ratio is “100%”. Therefore, although the number of songs is narrowed down, there is an effect that the music that matches the preference of a predetermined user can be specified with high accuracy.

Via a communication network using a general public telephone line, ADSL or optical communication line. Then, for example, a karaoke host device (H) and each karaoke performance device (P) are connected via a router (not shown) using a VPN (Virtual Private Network) managed by a karaoke provider using the Internet (Ni). Each router assigns an IP address to each karaoke performance device (P, P...) By a built-in DHCP (Dynamic Host Configuration Protocol) server function, and the MAC (Media Access Control) address and the IP address are assigned to each router. A communication table is created by associating these with each other.

  The karaoke host device (H) logged in to the karaoke system from any karaoke performance device (P) connected to the network in addition to the music information database storing the karaoke data of a large number of songs. A singing history for each user can be collected, and based on the singing history, as will be described later, a ranking list for each user arranged in order of singing frequency is created and stored for each user.

  In order to collect the singing history of each user who logs in to the karaoke system from the karaoke performance device (P), this karaoke host device (H) is a karaoke remote controller with user ID acquisition means in this embodiment. A device is used. The user ID acquisition means of the present embodiment is specifically an ID card reading / writing device equipped with a non-contact IC module, and specifies the user ID linked to the card ID. Is. However, the present invention is not limited to this, for example, a mobile phone with an IC function in which an IC module is built in a mobile phone, a mobile phone having a blue tooth mechanism as a short-range wireless communication means, or a password A user ID acquisition unit having a mechanism that relies on a biometric identification function such as an input device or a fingerprint or a voiceprint may be used.

  The karaoke performance device (P) is a kind of computer application device, and FIG. 2 shows a hardware-based configuration example of the karaoke performance device. Specifically, the central control means (1) is a computer main body including a CPU, a RAM, a ROM, and the like, and comprehensively controls various functional means. Further, as a large-capacity storage means, an HDD (2) and an optical disk device (5) for reproducing a CD-ROM or DVD-ROM, or a communication control device for communicating with the karaoke host device (H) via the VPN (4), operation input means from the user, operation processing means (3) for responding to the user, music generation means for generating an acoustic signal of accompaniment music based on MIDI music performance data (7), an acoustic device (8) for mixing an acoustic signal from accompaniment music or a karaoke microphone (M), further amplifying and emitting sound from the speaker (S), CRT, LCD, PDP, etc. Display (D) and video processing means (6) for processing video data and image data to be displayed on the display (D). The operation processing means (3) corresponds to the karaoke remote control device (R) provided with short-range wireless communication means (IrDA, infrared LED, infrared light receiving element, etc.), and also corresponds to the operation panel of the apparatus main body. It is configured.

  FIG. 3 shows a user-specific login instruction interface display screen of the remote control device. A user interface (R1) mainly composed of a liquid crystal display with a touch sensor is provided on the front surface of the remote control device of the present embodiment to provide a GUI (Graphical User Interface) environment, and through a dialogue by this GUI environment. In addition to login instructions for each user, the search function is realized by searching the music index database and displaying the results. This display screen is provided with a button row with user-specific facial photos, a “login” button for logging in to the karaoke system, a “logout” button for logging out, and the like. According to the operation method, first, after selecting the “login” button, the user ID associated with the user ID is acquired by loading the user ID acquisition unit with the user's ID card. The login to is identified.

  Once the login is specified, the user's face photo registered in advance in the karaoke host device or if it is not registered in advance, newly registering the user's face photo taken using the digital camera function, A user identification interface in which a button with a predetermined user-specific face photo is posted for each user is created. Therefore, before or after selecting this button with a user-specific face photo, when any user reserves and registers a song and a song is played, the singing history for each user is collected at a predetermined timing. At the same time, based on the singing history, the karaoke host device creates a ranking list for each user arranged in order of singing frequency for each user.

  FIG. 4 is a conceptual configuration diagram of the ranking list for each user. Specifically, this ranking list is associated with a user ID for identifying a user (for example, “user a”), and within a preset period (for example, the past year: the whole May be the same or set for each user), and the song IDs sung by the user and the singing frequencies of the respective songs are recorded and arranged in order of the singing frequencies.

  The steps (2) to (4) according to claim 1, based on the process explanatory diagram up to the recommended music list creation shown in FIG. 5 and the flow conceptual diagram of the recommended music selection method of the present invention shown in FIG. 6. The step (3) described in claim 2 will be described in detail.

  First, when an arbitrary user logs in to the karaoke system from an arbitrary karaoke performance device, the tunes of a predetermined rank or higher in the user's ranking list and the others' ranking list are compared. For example, when the user a logs in, as shown in FIG. 5, the songs of “within 10th place” are compared in the user a and other user ranking lists, and the preset “5 or more songs” Search for a user-specific ranking list having “matching degree of 50% or more within 10th place”, and evaluating these as a ranking list of users whose preferences are similar to user a, It is a target of further narrowing down “common music”. This “degree of matching of 50% or more within 10th place” is a design item, so any setting can be used as long as efficient search is possible and it can be considered that the closeness of preference can be determined. It does not matter.

  In this embodiment, a user-specific ranking list for five users b to f corresponding to the user-a ranking list for user a is targeted, and if there is a common song between the ranking lists of a predetermined ratio or more. This is extracted and transferred to the karaoke performance apparatus. For example, if there is a “common music” that matches between “80% or more” ranking lists, specifically, in this embodiment, user b is excluded from all five users b to f. If there is a “common music” that matches at the rate of four users cf, this is extracted and transferred to the karaoke performance device to which the user a is logged in. A recommended music list based on the extracted music is created and presented as appropriate.

  In the above embodiment, the same condition may be satisfied between different users, but in this case, of course, it is extracted as “common music”. Also, the music common to the ranking lists of a predetermined ratio or more is set as the music common to all the ranking lists, and for example, in the above embodiment, the preference is approximated corresponding to the ranking list for each user a. If there is a song that is common to all the user-by-user ranking lists of users b to f, that is, if there is a song with a predetermined ratio of “100%”, a song that matches the preference of user a is identified with high accuracy. it can.

  Next, based on FIG. 6, the flow of the recommended music selection method of the present invention will be described. First, when an arbitrary user logs in to the karaoke system from an arbitrary karaoke performance device (step: S1), when the user sings (S2), the singing history data is transmitted to the karaoke host device at a predetermined timing. And a singing history for each user is collected (S3), and based on the singing history, a ranking list for each user is created that is arranged in order of singing frequency for each user (S4).

  On the other hand, when an arbitrary user logs in at the karaoke performance device (S1), if there is a ranking list of the user, the songs in the ranking list of the others are compared with each other (S5). By comparing the music pieces, a ranking list of others having a degree of coincidence of a predetermined number of songs or more is searched (S6), and the ranking list searched for is shared among the ranking lists of a predetermined ratio or more. The music to be played is searched (S7), and the presence or absence of common music that satisfies the condition is determined (S8). If there is, it is extracted and transferred to the karaoke performance device (S9), and if not, this operation ends. When the common music data is transferred to the karaoke performance device, a recommended music list based on the extracted music is created (S10) and presented at an appropriate timing, such as when there is no music reservation or between music performances ( S11).

  As described above in detail, according to the recommended music selection method of the present invention, according to the recommended music selection method, from the collected singing histories for each user, sorted by singing frequency and created by user. Based on the ranking list, a user whose preference is approximated can be identified by comparing songs of a predetermined user and others of a predetermined rank or higher. If there is a song that is common among the rank lists for the rank list, a list of recommended songs is extracted, and a recommended song list is created and presented as appropriate. Can be recommended.
