Description

  The present invention relates to a technique for accurately presenting music information related to a performance music selected by a user to a user in a karaoke system.

  In the karaoke box exchange behavior, after visiting the group, each person uses a so-called `` song book '' or `` electronic quick sample '' to select the song he wants to sing, input this as a request to the karaoke device, It is a general way of enjoying to be a singer and a listener in order.

  However, in the case of the above-mentioned way of enjoying, there are people who are reluctant to become a singer and do not easily select and sing songs. It is speculated that such reluctant people have no repertoire that they can sing well, and often do not think or remember what to sing on the spot .

  In this way, there are quite a few situations where you can sing that song if you say it, and it is important to make this “reluctant group” in the karaoke box go to singing.

  One of the marketing methods currently used to solve the above problems is a method called “recommendation” or “recommendation”. It can be considered that this is a technique that has been widely used in online mail order sites (see, for example, Patent Document 3) also introduced into a karaoke box.

Therefore, the following (a) to (d) are known as karaoke apparatuses that solve the above-described problems.
That is, (a) a karaoke device is known that generates a recommendation list by a combination of a performance history of the karaoke device and a nationwide ranking distributed from a host (for example, see Patent Document 1).

  (B) A karaoke apparatus is also known that aggregates performance histories at a host, generates and distributes a total result according to the music selection order, and generates a recommended list by referring to the total result in the karaoke apparatus (for example, , See Patent Document 2).

  (C) Also, the performance history including the customer ID is aggregated by the host, statistical information in which the customer attributes are proportioned is generated and distributed, and the recommendation list is generated by referring to the statistical information with the karaoke apparatus. A karaoke apparatus is known (for example, refer to Patent Document 2).

(D) Also, a karaoke apparatus is known in which performance histories are totaled by a host, a total result is generated and distributed for each genre of music, and a recommendation list is generated by referring to the total result in the karaoke apparatus. (For example, refer to Patent Document 2).
JP 2004-184690 A (pages 3 and 4, FIG. 1) Japanese Patent Laid-Open No. 11-52965 (4th and 5th pages, FIG. 1) JP 10-91684 A (page 4, FIG. 12)

However, the karaoke apparatus as described above has many mounting problems as follows.
That is, in the karaoke apparatus as described in (a) above, since the recommended information is generated based on the performance history of one karaoke apparatus, it takes a considerable amount of time to accumulate samples for which the function becomes practical. There was a problem of requiring.

  In addition, in the karaoke apparatus as described above (b), since the relevance information of the performance music is generated only by the music selection order, there is a problem that there is a high possibility that a recommended list with poor practicality is generated. It was. This is due to the following reason. This is because even musical pieces that are not related to each other may be judged to be related to each other only because the music selection order is continuous. On the other hand, even performance music pieces that are related to each other may be judged to be unrelated to each other only because the music selection order is not continuous.

  Further, in the karaoke apparatus as described in (c) above, since it is required to identify the customer of the karaoke box at an individual level, the apparatus becomes expensive and collects performance histories from more users. There is a risk of hindering the spread of the device, which is the premise of

  Further, in the karaoke apparatus as described in (d) above, since the relevance information of the performance music is generated only by the genre of the performance music, there is a problem that unexpected relevance beyond the genre cannot be extracted. This is due to the following reason. It is considered that a relevance with unexpectedness beyond the genre cannot be extracted because the performance karaoke performance of the specific genre only presents a list of performance tunes having a high frequency in the genre. In addition, for example, when the genre of performance music is excessively subdivided, the range of extracting related performance music may be narrowed, and it may be difficult to present the performance music that matches the user's preference. On the other hand, for example, when the genres of performance music are not so subdivided, there is a possibility that the range of extracting related performance music becomes wide and it is merely a presentation of ranking.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a user with accurate information about music pieces related to a musical piece selected by the user in a karaoke system. Is to be provided by a simple method.

Considering that the specific group is present, it is conceivable to extract the performance history of the music played by the specific group from the performance history information stored in the performance history storage means as the group performance history information.

  In addition, the following (e)-(g) can be considered as a specific example of the above-mentioned exit detection means. That is, (e) as in claim 4, when the user is provided with operation means (10) for input operation, and the exit detection means performs a simultaneous cancellation operation on the operation means, the karaoke It can be considered that a specific group has left the place where the device is installed.

  If comprised in this way, when a specific group leaves a karaoke room, it can be considered that the specific group left automatically by simultaneous cancellation operation of the karaoke apparatus which the clerk of a karaoke store performs, for example.

  Further, (f) a configuration may be considered in which it is determined that the user leaves the room based on a signal from the POS register. Specifically, as in claim 3, when the exit detection means obtains a signal from the external terminal (2) indicating that the specific group has exited from the place where the karaoke device is installed, It can be considered that the specific group has left the place where the karaoke apparatus is installed. As a specific example of the external terminal, a POS cashier accounting device (2) can be considered.

[Description of karaoke performance processing]
Below, the process procedure of the karaoke performance process which CPU14 of the karaoke apparatus 1 performs is demonstrated based on the flowchart of FIG. 5, and FIG. FIG. 11 is an explanatory diagram showing the connection status of the online karaoke apparatus 1, the POS cashier accounting apparatus 2, and the collection / distribution center 50.

This karaoke performance process is repeatedly executed while the karaoke apparatus 1 is activated.
First, the process shifts to a karaoke performance loop process (S101 to S111). When the loop process starts, the process waits until a music selection operation is performed (S102). Specifically, with reference to the reserved music list, the process waits until the reserved music is registered in the reserved music list by the music selection operation. If the reserved music is registered in the reserved music list, a performance process (S103) for playing the reserved music is executed. Then, information regarding the played karaoke performance piece is added to the performance history (S104).

  Subsequently, a “recommendation” display process is executed (S105). Specifically, recommendation information, which is information registered in association with the played karaoke performance song, is read from the recommendation DB and displayed on the monitor 24 (see FIG. 10). Then, the “recommendation” selection process is executed (S106). Specifically, the karaoke performance music selected from the recommended information displayed on the monitor 24 is registered in the reserved music list as the reserved music.

  Subsequently, it is determined whether or not clearing information indicating that the specific group has left the karaoke room and settled has been received from the POS cashier accounting apparatus 2 (S107). When it is determined that the settlement information has not been received from the POS cashier accounting apparatus 2 (S107: NO), the process proceeds to S110. On the other hand, when it is determined that the clearing information has been received from the POS cashier accounting device 2 (S107: YES), the specific group performs based on the performance history of performing karaoke using the karaoke device 1 while in the room. History pack data is generated, and the generated performance history pack data is recorded in a performance history pack data recording area in the HDD 13. Then, the performance history is cleared (S109).

  Then, it is determined whether it is a communication time zone (S110). When it is determined that it is not the communication time zone (S110: NO), the karaoke performance loop process is terminated and the present process is terminated.

  On the other hand, when it is determined that it is the communication time zone (S110: YES), the communication process (S112 to S116) is started in parallel with the karaoke process. Note that this communication process is repeatedly executed in the communication time zone.

  In this communication process, the session connection with the collection / distribution center 50 is executed (S112), and the distribution content transmitted from the collection / distribution center 50 is received (S113). Then, the performance history pack data is transmitted to the collection and distribution center 50 (S114), and the recommendation DB is received / updated (S115). Subsequently, the session connection with the collection / distribution center 50 is terminated (S116), and this communication processing is terminated.

[Description of host communication processing]
The processing procedure of the host processing executed by the collection / distribution center 50 will be described below with reference to the flowchart of FIG. 6 and FIG.

This host communication process is repeatedly executed while the collection / distribution center 50 is activated.
First, the process proceeds to a loop process (S201 to S209) of host communication. When the loop process starts (S201), the process waits until a connection request is received from the karaoke apparatus 1 (S202). When the connection request from the karaoke apparatus 1 is received, the session connection with the karaoke apparatus 1 is executed (S203). The distribution content updated between the end of the previous session connection and the present time is read from the content DB, and the read distribution content is transmitted to the session-connected karaoke apparatus 1 (S204). Subsequently, the performance history pack data transmitted from the karaoke apparatus 1 is received (S205), and an update process for updating the song relevance DB based on the received performance history pack data is executed (S206). At this time, the recommendation DB is also updated based on the received performance history pack data. Details of this process will be described later. Then, the recommended DBs of the karaoke device 1 and the collection / distribution center 50 are compared, and the difference is transmitted to the karaoke device 1 (S207). In the karaoke apparatus 1, the CPU 14 updates the recommended DB based on the transmitted difference data. As a result, the content of the recommendation DB of the karaoke apparatus 1 and the content of the recommendation DB of the collection and distribution center 50 are the same.

Subsequently, the connection session with the karaoke apparatus 1 is disconnected (S208), the loop process of the host process is terminated (S209), and this process is terminated.
[Description of song relevance DB update processing]
Below, the process sequence of the music relevance DB update process executed by the collection and distribution center 50 will be described based on the flowchart of FIG. 7 and FIG. 11.

This music relevance DB update process is a subroutine of S206 of the host communication process.
The process proceeds to a loop process (S301 to S310) of pack data processing until the pack data is exhausted. First, one performance history pack data is read from the performance history pack data transmitted from the karaoke apparatus 1 and temporarily stored (S302).

Here, the process proceeds to a loop process (S303 to S308) of the performance history process until the performance history is exhausted.
First, one song is extracted from the history number n with reference to the song relevance DB, and the relevant field of the DB is selected as the related source song (S304). If there is no applicable field, a new field is added. Next, the related coefficient α is calculated for all histories except the nth (see FIG. 9). Specifically, a value obtained by adding the related coefficient addition value calculated based on the following equation (1) to the related coefficient is set as the related coefficient α.

Related coefficient addition value = number of songs selected ÷ number of people entering room + music selection order coefficient (Equation 1)

Note that the performance history pack data is referred to for the number of music selections and the number of people entering the room, and the music selection order coefficient table stored in the collection and distribution center 50 is referred to for the music selection order coefficients.

  Then, the calculated related coefficient α is added to the cell in the field (S306). If there is no corresponding cell, a new cell is added. Further, the cells in the field are sorted in ascending order of related coefficient values (S307).

When there is no performance history, the loop processing (S303 to S308) is terminated, and the process proceeds to S309.
In S309, the song relevance DB update field is reflected in the recommendation DB with reference to the music relevance DB. Note that the updated field is copied by reducing the number of cells from the top to four.

When the pack data is exhausted, the loop processing (S301 to S310) is finished and the music relevance DB processing is finished.
