Description

  The present invention is a dedicated background image specially prepared for a favorite artist only for a user who satisfies a predetermined condition at the time of playing a karaoke song, for the motivation to arouse the singing of the karaoke user. The present invention relates to a karaoke system.

  In the conventional karaoke system, a background image that matches the image of the music is displayed with the aim of visual effects when the karaoke music is played. By the way, in general, since the background video data is moving image data, the amount of data is enormous compared to the music data. Therefore, the transmission capacity of the currently used communication line is too heavy, and background video data is recorded in advance on a recording medium such as a DVD or CD, and these are distributed to each karaoke store. In addition, since the capacity of the recording medium is limited, it is not efficient to prepare background video data for the number of songs, and versatile background video data is prepared. Usually, a plurality of common genres are used. The same background video data is shared for the music. Specifically, the genre data of the music is carried in the header portion of the music data, background video data corresponding to the genre data is extracted from a plurality of candidates, and is displayed during the performance of music having a common genre.

  Furthermore, in a recent karaoke system, a versatile background video for a long time is stored in the video database, and this stored video for a long time is selected as a background video according to the performance music. It is supposed to be played. As a selective playback method, a video of a background video in which a video for a long time is managed by assigning a video segment identifier for each segment, and a segment video to be reproduced for each song is described by a permutation of the video segment identifier. Methods using data have been proposed. In this case, the karaoke performance device that refers to the script data of the performance music recognizes the video segment identifier according to the script, and plays back the segmented video corresponding to each other.

  Conventionally, many techniques related to such background images have been conceived. For example, Patent Literature 1 discloses a technology that opens a catalog of background videos of karaoke music to a PC so that information relating to the background video is opened to the user and the selection is free. Alternatively, in Patent Document 2, a unique background image can be displayed for each piece of music with a newly added unique background image while continuing to use existing song data for which a unique background image is not prepared. A system is disclosed. Further, in Patent Document 3, when script data for sequentially specifying a plurality of segmented videos constituting a background video is not set, a technique for substituting script data having a predetermined classification attribute in common with the music piece Is disclosed.
