Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for contesting a karaoke video work, and more specifically, when a karaoke performance device plays a karaoke music piece, a user can select from a plurality of karaoke video works dedicated to the music piece. The present invention relates to a method for displaying a specified video work in accordance with karaoke accompaniment music and conducting a karaoke video work contest based on the usage record of each karaoke video work. The present invention also relates to a karaoke system and a karaoke performance device for conducting a karaoke video work contest.

[0002]

BACKGROUND OF THE INVENTION A karaoke performance device is a device for outputting an acoustic image in synchronization with karaoke accompaniment music and a lyrics image. Normally, the lyrics image is displayed with a moving image as a background. The karaoke performance device for the current mainstream online karaoke system is
Karaoke data for many songs, which is the origin of the karaoke music and lyrics images, and long-time moving image data, which is the origin of the background video, are individually managed and stored.
When a karaoke piece is played, short-time video data extracted from a long-time video data is reproduced and connected to edit a series of background videos. That is, there is no dedicated background image for each karaoke song, and the images for a long time are reused. Currently, for each karaoke song, it is specified for each karaoke song which part of the video for a long time is to be taken out and connected, so to prevent the background video from being displayed far from the contents of the accompaniment music and lyrics, It is devised.

Before the advent of the online karaoke system,
A karaoke performance device that reproduces "packaged software" in which accompaniment music, lyrics images, and background images are integrally recorded on an optical video disc has been mainstream. The background image displayed by this karaoke performance device is a specially produced song for each song, and is an unvoiced ultra-short movie produced to fit the contents of the accompaniment music and lyrics. You can start by creating a combined scenario.

[0004]

As described above, as a background video organization system, a system in which video data for a long time is reused (shared video system) and a system in which a video created exclusively for music is reproduced ( There is a dedicated video system). With the shared video system, it is not necessary to create video data dedicated to the new karaoke song in time with the announcement of the song, so the cost of creating the video data can be suppressed and the release of the new song can be supported quickly. There is an advantage. However, I can't expect a karaoke video that can be enjoyed that suits the content of the music, such as a dedicated video system, and if I keep karaoke for a long time, I get tired of getting the same video over and over again. Especially for people who are singing, watching karaoke videos is a great fun, but it is not enough.

The dedicated video system can match the content of the music with the background video, and some of them are so good that the video itself can be used as one video work. On the other hand, there is a drawback that it takes a lot of time and money to create a video. Further, the same background image is displayed when the same music is played, and the karaoke user eventually gets tired of the image.

By the way, due to the recent popularization of digital video cameras and the high performance and low price of personal computers, it is necessary to edit and edit images, which require expensive and large-scale equipment.
I made it possible to do the act of processing well in a general household. Some people create highly complete images that can be called "video works".

Therefore, the inventors of the present application have paid attention to those who are "self-proclaimed" image creators who create these excellent image works. People who call themselves filmmakers want to have their work seen by more people and to compete with other filmmakers to test their abilities. Instead of providing a venue for this, I decided to have him create a video work exclusively for karaoke songs.

In Japan, tens of thousands of performance devices for communication karaoke systems are scattered in various places, and many people enjoy karaoke on a daily basis. Taking advantage of this environment, if many people enjoying karaoke can watch their own karaoke videos, it should be possible to satisfy the self-proclaimed video artist's creativity. Furthermore, I thought that if the contest for the karaoke video works provided to us was held, the video artists would be more competitive and would produce better video works.

On the other hand, a karaoke company can obtain a video work dedicated to a musical piece without incurring a cost. For a karaoke user, various video works suitable for the content of the music can be matched with the accompaniment music. There is also the advantage of being able to see.
