Description

  The present invention relates to a karaoke distribution system using a portable information terminal (for example, a mobile phone), and more specifically, it can be easily used by using the information communication function of the portable information terminal, and still has high quality. The present invention relates to a karaoke distribution system capable of providing karaoke.

  A conventional karaoke song request is, for example, selecting a desired song from a list of karaoke songs that can be searched using the title of the song or the name of the singer as a keyword, and an identification code attached to the song is remote-controlled. And transmitting information to the karaoke apparatus main body.

  In addition, recently, a touch panel type terminal placed in a karaoke room is used to touch the title or singer's name of a desired song, thereby transmitting the song information to the karaoke device body, thereby Requests are also increasing.

  However, it is surprisingly difficult to select a desired song from the karaoke song list book, and considerable time is wasted especially in scenes where a large number of people enjoy karaoke. Also, when using a touch panel type terminal, the number of terminals is limited. Therefore, when there are a large number of people, the waiting time for selecting a song for each person is wasted time.

  Therefore, in order to solve such a problem, for example, Patent Document 1 discloses a karaoke distribution system that uses a function of a recent portable information terminal. According to this technology, since the server machine and the mobile phone are connected via the mobile phone communication network, the mobile environment does not depend on the fixed connection environment to the network like a conventional communication karaoke. It is said that you can enjoy online karaoke with the latest contents even if you are in an area where you can communicate with a mobile phone even if it is below.
