Description

  The present invention relates to a music search result display system for preferentially displaying a search result according to a predetermined condition in music search when a karaoke music is reserved for music selection.

  The currently popular karaoke system uses the music search function of the karaoke remote control device to search for karaoke music that you want to sing by entering search conditions such as singer name, song name, fashion age, and music genre. Can be done. The search results are displayed in a list on the display screen of the karaoke remote control device, and performance reservations can be made by designating the target music from the displayed music.

  In a general search result display, music information (music name, singer name, etc.) that matches the search conditions is displayed in the order of 50 sounds. For this reason, when a large number of music pieces are extracted in accordance with the search conditions, they do not fit on one page of the display screen. Therefore, the page turning operation must be repeated until the target music piece is found, which is troublesome for music search. There was an inconvenience that it took time.

  Accordingly, various techniques for solving such inconvenience have been proposed (see Patent Document 1 and Patent Document 2). The technique described in Patent Document 1 is intended to make it easier and faster to use a karaoke remote control device equipped with a music search engine when a user requests a karaoke performance device for a desired song. This is a technology that makes it possible to identify codes. This search result display system sorts the music information with a high performance frequency or reservation frequency in descending order when displaying a list of hit music information based on an arbitrary search condition for the music database. Priority is displayed at the beginning of the list of search results.

  The technique described in Patent Document 2 describes the number of performances and weighting information as priorities in addition to a song number, a song title, and a singer name for each song data in a music search database. The weighting is, for example, information in which numerical values of frequently sung songs and new songs are set high, and are regularly received from the distribution center. When the user inputs a keyword such as a song name, the karaoke performance device searches a database for searching for a song with this keyword, and sorts and outputs the search results in the order corresponding to the priority.

  It is certain that the target music can be found more easily and quickly by displaying the search result using the music with a high reservation frequency or high performance frequency as a preferential display condition as in the prior art described above. It is. However, the reservation frequency and performance frequency, which are prioritized display conditions in the conventional technology, are determined based on the fact that the reservation frequency and performance frequency are high, and this alone accurately reflects the user's preference. It was hard to say that it was a priority display condition.

  For example, the user's preferences change from moment to moment according to the trend, and even if the search results are sorted and displayed based on the fact that the number of reservations and performances is large, the convenience of the user is improved. May not be possible. In addition, the user's preference is the difference between the form of a karaoke box used during the day, the so-called night shop that sings with drinking, the user's age, occupation, etc. Obviously, it varies depending on various factors such as strata and regional differences. In this case, even if the search results are sorted and displayed according to general and average priority display conditions, the convenience for the user cannot be improved.

  The technique described in Patent Document 2 described above weights the priority of search result display for each item indicating the number of performances and the characteristics of music data (music for karaoke BOX, music for lounge, new music, etc.). The information is sorted by the sum of the number of performances and the weight of each item. However, in the technique described in Patent Document 2, detailed priority display conditions based on attribute information are not set for a predetermined number of karaoke songs that have already been played. However, it is difficult to say that it accurately reflects the user's preference.

  The present invention has been proposed in view of the circumstances described above, and provides a music search result display system that can easily and quickly find a target music that accurately reflects the preference of a user who uses a karaoke system. The purpose is to provide.

  The present invention has the following features in order to achieve the above-described object. That is, the music search result display system of the present invention is a system for preferentially displaying a search result according to a predetermined condition in music search when a karaoke music is reserved for music selection, and includes a music index database and a music search Means, a performance history management means, a priority display ranking means, and a search result display control means.

  The music index database is a database configured by associating a plurality of attribute information as search conditions in music search for each karaoke music to be played. The music search means is a means for searching the karaoke music corresponding to the attribute information as the input search condition with reference to the music index database. The performance history management means is means for managing performance history information of a predetermined number of karaoke songs that have already been played in the performance history management database. The priority display ranking means is a means for obtaining a performance frequency for each piece of karaoke song attribute information managed in the performance history information, and ranking attribute information as a priority display condition based on the performance frequency. . The search result display control means is a means for preferentially displaying the corresponding karaoke music from the search results in the music search means using the attribute information that has been ranked higher in the ranking as a priority display condition.

  In the music search result display system configured as described above, the karaoke music to be played is a song ID, song name, singer name (artist name), lyrics of the singing part, fashion period, music genre classification, or duet song. A music index database is constructed by linking such attribute information. A user who makes a music selection reservation uses, for example, the function of music search means (search engine) provided in the karaoke remote control device to input search conditions (song title, singer name, trend time, attribute information such as music genre classification). Thus, the target karaoke music is searched.

  On the other hand, in the music search result display system of the present invention, information related to a predetermined number of karaoke songs that have been played is stored as performance history information, and is managed in the performance history information by the function of the priority display ranking means. The performance frequency for each piece of karaoke song attribute information is obtained, and the priority display conditions are ranked.

  Here, for example, when the performance frequency of the karaoke music piece having the music genre category “JPOP” is the first rank and the search is performed using the popular period “1980s” as a search condition, the music having the performance frequency of the first rank With the genre classification “JPOP” as a priority display condition, the corresponding karaoke music is preferentially displayed.

  Further, when the search condition in the music search means matches the priority display condition with the higher rank, the attribute information of the next rank of the attribute information set as the priority display condition can be set as the priority display condition. It is. For example, in the above-described example, when the performance frequency of the karaoke music piece having the music genre category “JPOP” is the first rank and the search is performed using the music genre category “JPOP” as a search condition, the search condition and priority are given. The display conditions are the same. Therefore, in this case, the corresponding karaoke music piece is preferentially displayed using the attribute information (for example, the fashion period “2000s”) with the performance frequency of the next order (second order) as the priority display condition.

  Note that the priority display condition used by the search result display control means is not limited to attribute information of the highest order, but may be combined with attribute information of the next order. That is, as the priority display condition, the corresponding karaoke piece is preferentially displayed using the first rank attribute information and the second rank attribute information as the priority display condition.

  According to the music search result display system of the present invention, the search result can be preferentially displayed according to a predetermined condition in the music search when the music selection reservation is made for the karaoke music. At this time, based on the performance history information of a predetermined number of karaoke songs that have already been played, the performance frequency for each attribute information is obtained, and the attribute information that is the priority display condition is ranked based on the performance frequency, The corresponding karaoke music is preferentially displayed using the attribute information in the ranking as the priority display condition.

  Therefore, since priority display is performed based on detailed priority display conditions that accurately reflect the user's preferences based on the attribute information of karaoke music pieces played within a predetermined period, the user can easily and quickly You can find music to play.

  If the search condition set by the user matches the priority display condition determined based on the performance frequency, the attribute information of the next rank of the attribute information set as the priority display condition is set as the priority display condition. Thus, since priority display is performed in consideration of the potential preference, the target music can be found out more easily and quickly.
