Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke system.

[0002]

2. Description of the Related Art Generally, a karaoke song is desired to have more new songs and popular songs to be sung, and the more songs, the more pleasing to the user. However, the karaoke apparatus has a limited number of songs that can be played. For example, in a karaoke apparatus using a conventional video disc autochanger, the upper limit of the number of songs can be determined by the number of video discs that can be stored. If the owner of a karaoke store increases the number of new songs, the capacity of the karaoke machine will be full sooner or later.

When the capacity of the karaoke device that has been used up to now becomes full, old songs that are no longer sung or unpopular songs are replaced with new songs that are sung or popular songs. It is common.

It is also common to introduce a new karaoke device with a larger capacity.

[0005]

However, in the case of replacing music like the former, not only is it costly, but the media such as the video disk board and cassette tape that have been used up to now are wasted. Moreover, the fact that the number of songs is small cannot be improved by this method. If the cost is allowed, it is preferable to introduce a new karaoke device having a large capacity like the latter, but if the new karaoke device is introduced and the old karaoke device is discarded, the old karaoke device is wasted.

For this reason, if a new karaoke apparatus and an old karaoke apparatus are installed side by side and a user uses them, the input operation differs for each apparatus, and the operation becomes complicated, which is not preferable.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a karaoke system which makes use of different types of karaoke devices and does not deteriorate the operability.

[0008]

In order to achieve this object, a karaoke system of the present invention comprises a first karaoke device for playing a song corresponding to the first signal based on the first signal,
A second karaoke device that plays a song corresponding to the second signal based on the second signal, and specifies a desired song for each of the first karaoke device and the second karaoke device. Inputting means, a judging means for judging which karaoke device the music designated by the input means is to be played, and when the judging means judges that the karaoke device is to be played. If the first control means for outputting the first signal to the first karaoke apparatus and the judging means judge that the second karaoke apparatus is to be played, the second karaoke apparatus is judged to be Second control means for outputting two signals.

[0009]

In the karaoke communication system of the present invention having the above structure, when the desired music is specified from the input means by specifying either the first karaoke apparatus or the second karaoke apparatus, the input means is input. If it is determined that the karaoke device is to be played by the karaoke device, and the determining device determines that the karaoke device is to be played by the first karaoke device, the first control device determines The first signal is output to the first karaoke device. Further, when the judging means judges that the second karaoke apparatus is to be played, the second control means outputs the second signal to the second karaoke apparatus, and the first or second signal is outputted. The music corresponding to each signal is played in a predetermined karaoke device based on the above.
