Referring to the drawings, the karaoke system is connected to the MIDI data server 2 and the portable telephone 10 through a public communication network. The portable telephone 10 is mounted to the karaoke data station 20.

The server 2 includes a plurality of karaoke data, and transmits the selected karaoke data to the portable telephone 10 in response to the karaoke data request from the portable telephone 10.

The portable telephone 10 downloads the selected karaoke data and transmits it to the karaoke data station 20.

And the karaoke data station 20 is a data processing device for processing the typical audio data, the circuit components for the karaoke function (e.g., control device, storage device, MIDI decoder, video codec, audio codec, mixer) , Amplifiers, speakers, and microphones). At least one karaoke data is stored, and the downloaded karaoke data is stored under the control of the portable telephone 10 or the karaoke data for the karaoke function is reproduced and processed.

The karaoke data is provided, for example, in a MIDI data format. Because MIDI data does not record sound directly, you can change the parameters of the control action at any time, unlike MP3 format audio files that record sound directly. That is, it is possible to process the parameters of all control operations related to audio effects such as instrument timbre, tempo, key or pitch. And since MIDI data is much smaller than other audio data containing sound, it is easy to transfer data between the server and the mobile phone. For example, about 14 pieces of general audio data are stored on a CD-ROM, and about 150 songs are stored in an MP3 file format, but MIDI data can be stored much more than these. MIDI data is also easy to edit. For example, even the already completed MIDI data can be changed for each sound source, and even various functions such as instrument sound, playing speed, and pitch of the playing sound can be added or deleted.
