Description

  The present invention relates to a karaoke system, and more particularly, to a karaoke system comprising a karaoke device and a karaoke remote control device having a bidirectional communication function between the karaoke device and the remote control device having a music search function. .

There is a remote control device having a function of searching for music by inputting a part of a song name or a singer name in a conventional remote control device of a so-called communication karaoke device (see Patent Document 1). These remote control devices hold a search database for performing a search in the remote control device main body, and the search database is updated wirelessly from the host. Further, such a conventional remote control device can make a request to the communication karaoke device main body based on the searched music, but communication between the remote control device and the communication karaoke device main body is performed by the communication karaoke from the remote control device. It is a one-way communication function to the device body.
Japanese Patent Laid-Open No. 10-105184

  In the case of such a remote control device, depending on the update status of the search database provided in the remote control device, there is a data mismatch between the music data actually held in the communication karaoke device main body and the search database of the remote control device. For example, new tunes that can already be sung in the online karaoke device main body may not be displayed in the search results even if searched by the remote control device, or based on the music data searched by the remote control device. There is a problem that even if a request is made to the apparatus main body, the music does not exist on the communication karaoke apparatus main body side.

  In addition, when using a plurality of remote control devices for a single online karaoke device, the search results differ depending on the remote control device even if the search is performed under the same conditions, unless the search database update status of each remote control device is the same. There was also a problem.

  In addition, when there are a plurality of communication karaoke apparatus main bodies in a karaoke box or the like, the music data of the communication karaoke apparatus main body is updated individually, so the music data held in each communication karaoke apparatus is not necessarily the same. There is also a problem that the music that can be requested by the communication karaoke apparatus A using the remote control device cannot be requested by the communication karaoke apparatus B.

  In addition, there is a problem that an IC memory or a hard disk device for holding a search database is required in the remote control device main body, which leads to an increase in cost, or when a single remote control device is compatible with a different model or a communication karaoke device of a different manufacturer. There is a problem that it is necessary to maintain a search database for multiple models and manufacturers in the remote control device, and it is necessary to communicate frequently for data update, but it cannot be used during data update. The type that manually updates the data is troublesome, and the type that automatically updates the data is also when the remote control device is not used at night or when the store is closed Therefore, even when the remote control device is not used, such as at night or when the store is closed, the power is turned on. If there is a need advance, there is a problem that electricity rates are increased.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a karaoke system that can reliably request a music piece searched for by a remote control device.
