PURPOSE:To eliminates the need to make a request from a KARAOKE terminal in a broadcast system and to enable the terminal to receive desired music in a realistic wait time by connecting a center station to the KARAOKE terminal through a line having plural channels. CONSTITUTION:Plural channels CH1-CHn are set to the line 2 by frequency division and the center station 1 repeatedly sends plural music data D1-Dm which are different, channel by channel. Then the KARAOKE terminal 3 selects and receives desired music data among D1-Dm with the combination of the channel number and music number. Namely, the KARAOKE terminal 3 has a mechanism which selects the channels CH1-CHn including the desired music data D1-Dm and a request data pickup mechanism which takes the desired music out of the selected channel. Further, a radio line such as a broadcast wave or existent wired line is used as the line 2 which connects the center station 1 to the KARAOKE terminal 3. |
