BACKGROUND OF THE INVENTION
The present invention relates to a karaoke playback apparatus that plays back a video with audio selected based on a tune genre of karaoke performance between songs.
[0002]
[Prior art]
As is well known, the communication karaoke system is a large-scale computer network in which a large number of karaoke terminal devices widely deployed on a nationwide scale and host devices operated by business operators are connected by communication lines, and voice information It is also a multimedia system that handles text information and video information. Therefore, by utilizing the bidirectionality of the communication line, not only can new song software be supplied quickly, but also various application functions using network resources have been realized. For example, online karaoke operators collect operation records of each terminal device through the host device, check the function of each terminal device, remotely control individual terminal devices based on operation records and contract details, etc. An operation system and maintenance management system that are directly connected to karaoke operations are realized.
[0003]
On the other hand, from the viewpoint of providing karaoke music, the most popular communication karaoke system is the music / video separation type as is well known. In other words, a system for accumulating and reproducing karaoke data including accompaniment sound and lyrics information of karaoke music and synchronization information of both, and a system for accumulating and reproducing video data as a background for displaying lyrics Is different. When playing a requested piece of music, an image that matches the tone and atmosphere of the song is selected and displayed on the display.
[0004]
A certain video does not correspond to a specific music piece, but a large number of videos are classified according to the musical genre such as enka, pop, and rock. For example, when music pieces classified into the “enka” genre are reproduced, one video data appropriately selected from a plurality of images belonging to the “enka” genre is reproduced. Alternatively, a large number of short-time video data belonging to the “enka” genre are randomly selected, connected, and reproduced. That is, a considerably small amount of video data is appropriately shared with respect to the number of music pieces, so that it is possible to easily deal with new songs generated one after another, and the burden of video software production is reduced.
[0005]
[Problems to be solved by the invention]
Watching the video displayed on the background of the lyrics, like the enjoyment of music videos and background videos, is a big part of the fun of karaoke. In an expensive and very large karaoke player using an optical disc in which music and background video are recorded in a one-to-one correspondence, when playing a song, a specific video produced for that song must be created. Played. On the other hand, in the case of a music / video separation type karaoke reproducing apparatus, even if the same music is reproduced, different images are reproduced from time to time. For karaoke regulars, the latter can enjoy various background images, and this can be regarded as an advantage of the music / video separation type.
[0006]
However, the conventional online karaoke system is intended to reduce the burden of video software production by adopting a music / video separation system, and to reduce the image storage / playback system in the karaoke playback terminal with a small-scale system. On the other hand, the evaluation that the trendy new song can be sung immediately is very high, while the evaluation of the fullness and entertainment of the background video software is low. For example, a young regular customer who often sings new pop-related songs finds that the same video group is randomly combined and output repeatedly, and is quickly bored.
[0007]
The present invention has been made in view of the above-mentioned conventional problems, and its object is to provide a background video service using digital multi-channel broadcasting in addition to the advantages of a communication karaoke system using a communication medium such as a telephone network. The goal is to dramatically increase entertainment and fulfillment.
