Description

  The present invention relates to a karaoke system having a group opposition singing ability ranking function. More specifically, the karaoke host apparatus is connected to the host apparatus via a network communication line, and a user ID recognition function and a singing ability scoring function. The present invention relates to a karaoke system for mainly competing in singing ability ranking against group karaoke performance terminals.

  As is well known, the current karaoke performance device has a singing ability scoring function. This scoring function compares the singing voice input from the microphone during the performance of the karaoke music with the main melody of the karaoke accompaniment music, and scores based on the difference in the pitch and pronunciation timing. Specifically, a predetermined musical note area such as a phrase or measure is used as one scoring section in the performance process of the music, and the singer's voice signal input from the microphone and the reference data (reference) such as the main melody of karaoke accompaniment music are used. Compare each section. Then, the comparison results for each scoring section are tabulated and displayed, and finally tabulated from the start to the end of the performance of the accompaniment music, and the tabulated value is processed appropriately to create a scoring value.

  Also, the karaoke performance terminal that is the performance terminal of the communication karaoke system is connected to the karaoke host device via a network, and downloads karaoke data that is the origin of the generation of karaoke accompaniment music and lyrics telop from the host device, or the karaoke performance terminal itself The operation log is uploaded to the host device. Therefore, when the singing scoring function is used, scoring information such as scoring during music performance and final scoring results is transmitted to the host device. Currently, using this function, the host device collects scoring information from karaoke performance terminals distributed in various places, summarizes it into singing ability rankings, etc., and distributes the collected information to karaoke performance terminals in various places. The terminal appropriately displays and outputs the distributed information and presents the singing ability ranking information to the user.

  Conventionally, various techniques related to a karaoke system having such a singing ability scoring function have been conceived. For example, in Patent Document 1, by acquiring a user ID for a karaoke performance terminal to identify a user, it is recognized who sang what, and the scoring information is transmitted to the karaoke host device. The device discloses a technique for creating a singing ability ranking for each predetermined period such as monthly or annual based on the scoring information. Patent Document 2 discloses a technique in which a user designates an appropriate section in a music performance process and displays scoring information in the designated section on a display.

  Nowadays, a karaoke system is known in which a plurality of users form a group and can enjoy a group opposition battle in which singing ability is competed between groups. With this karaoke system, for example, requested music belonging to a group is specified and arranged by group ID, this is registered in a request reservation book, and the requested requested music is played alternately for each group ID. The song battle will proceed. Each karaoke performance terminal scores the singing ability each time the requested song is played, and competes in the ranks based on the results of totaling the scored results for each group.

Conventionally, many techniques related to a karaoke system for competing in singing ability ranking among groups have been conceived. For example, in Patent Document 3, scoring information scored in each room of the karaoke room by the client server karaoke LAN system is totaled in the karaoke server, various numbering information is processed, and the numbering information is displayed on the display in each room. Technology is disclosed. Furthermore, in patent document 4, the music ID and group (team) ID which are included in the remote control signal emitted from the remote control of the karaoke performance terminal are recognized, these are classified, the group-specific scoring information is totaled, and the total result is obtained. A technique for guiding and displaying a group competition score table based on this is disclosed. And in patent document 5, from the scoring history data which the karaoke host apparatus collected from each karaoke performance terminal, the average score table according to music which computed the average value according to music for every karaoke music was created, and this was made into each karaoke performance terminal. A technique for distributing to the Internet is disclosed.
Japanese Patent Laid-Open No. 10-055184 Japanese Patent Laid-Open No. 10-301588 JP-A-10-133669 Japanese Patent Laid-Open No. 11-095771 JP-A-11-265187

  In this way, the scoring display and the ranking display based on this are a guideline for the singing ability of the user, and in particular, competing for the ranking of singing ability by group opposition will also improve the singing ability and motivate to continue singing This is a very effective function in the current karaoke system. However, in the karaoke system for competing in the group competition, unlike the conventional system for displaying the singing ability ranking for each individual, the requested music ID, group ID, scoring information and winning / losing information are processed. However, the user IDs that make up the group are not centralized and managed by the karaoke host device, and the members that make up the group are used together at the specified karaoke performance terminals at karaoke performance terminals that are distributed in various locations. There was an inconvenience that we had to use this function only when we were doing it. Furthermore, naturally, scoring information for each user in the group is not managed, so the singing ability ranking for each member is not known, and each time a user sings, the scoring value for each member in the group Evaluation was not possible.

  Therefore, the present invention has an object to solve the above inconveniences. Specifically, in a karaoke system for competing for a singing ability ranking by group opposition, not all members are aligned at a predetermined karaoke performance terminal. , Even if singing individually at any karaoke performance terminal, you can compete for the ranking of group singing ability between groups, and each time the user sings, within the group about the scoring value The challenge is to provide a karaoke system that understands the evaluation of

  In view of the above problems, the present inventors record a scoring history for each song sung by the user for each user ID in the karaoke host device, and a predetermined group is set with a plurality of users. In addition, the group ID is registered in the scoring history of the user belonging to the group, and the scoring value is scored each time any user constituting the predetermined group sings at any karaoke performance terminal. In addition to recording in the history, the grading value of the group is calculated and recorded in the karaoke host device, and the singing ability ranking between the groups is calculated based on the grading evaluation value. A karaoke system that has the ability to solve the above-mentioned problems by building a karaoke system capable of competing and has the group opposition singing ability ranking function of the present invention It was conceived free.

That is, the karaoke system according to claim 1 of the present invention is
A karaoke host device is connected to the host device via a network communication line, and is mainly composed of a karaoke performance terminal having a user ID recognition function and a singing ability scoring function. A karaoke system,
(A) In a predetermined recording unit in the karaoke host device, a scoring history for each song sung by the user is recorded for each user ID,
(A) When a predetermined group is set with a plurality of users, the group ID is registered in the scoring history of the users belonging to the group,
(C) In any of the karaoke performance terminals, every time a user who composes a predetermined group sings, the scoring value is recorded in the scoring history in a predetermined recording unit in the karaoke host device. In addition, the scoring evaluation value of the group including the scoring value is calculated and recorded,
(D) Based on the scoring evaluation value, the rank of the group singing ability among the groups is specified, and the rank notation is displayed at appropriate timing with the display means attached to the karaoke performance terminal. It is characterized by.

  Further, in the karaoke system according to claim 2 of the present invention, in the karaoke system according to claim 1, the scoring evaluation value of the group is an average scoring value of the entire group for each music piece, and depending on the level of the average scoring value The rank of the group singing ability for the musical composition among the groups is specified.

  Furthermore, the karaoke system according to claim 3 of the present invention is the karaoke system according to claim 1 or 2, based on the scoring value each time an arbitrary user constituting a predetermined group sings. The rank of the singing ability of the user among the users of the group to which the user belongs is specified, and the rank notation is displayed at an appropriate timing with display means attached to the karaoke performance terminal. Features.

  According to the karaoke system of claim 1 of the present invention, when a grading history for each song sung by the user is recorded for each user ID in the karaoke host device, and a predetermined group is set, The group ID is registered in the scoring history of the users constituting the group, and the scoring evaluation value of the group is scored every time any user composing a predetermined group sings at any karaoke performance terminal. Since it is calculated and recorded including the value, it is possible to know the scoring information for each member making up the group, and it is not necessary for all members to be gathered together at a predetermined karaoke performance terminal as in the past. Regardless of the date and time at any karaoke performance terminal distributed in each place connected to the device, for example, each member sings individually Even, you can compete ranking group singing between groups, an effect such as a powerful incentive to continue to improve and singing of singing.

  Moreover, according to the karaoke system according to claim 2 of the present invention, in the karaoke system according to claim 1, the scoring evaluation value is an average scoring value for each piece of music, and depending on the level of the average scoring value, between groups. The ranking of group singing ability for the song is specified, but generally, the scoring evaluation value calculation method can be divided into “total score method” and “average score method” of each member's scoring value. Then, although the comparison of superiority and inferiority is simple and clear, if the number of singing is not limited to the same number or the number of members is not the same, it will lack fairness. Furthermore, when the ranking competition period is limited, the ranking in the middle of the period becomes inaccurate due to the difference in the number of singing, etc., so the superiority or inferiority is not well understood until the final counting. On the other hand, in the latter case, even if each member sings individually, the ranking during the period does not depend on the number of songs for each singing, so the member's competitive awareness continues during the period The effect of being able to stir up is produced.

  Furthermore, according to the karaoke system described in claim 3 of the present invention, in any of the karaoke systems described in claim 1 or 2, each time an arbitrary user who constitutes a predetermined group sings, based on the scoring value. Since the ranking of the singing ability of the user among the users of the group to which the user belongs is also specified, the evaluation within the group can be performed, so that the singing ability can be improved and the singing can be continued more powerfully. The effect is motivating.
