PROBLEM TO BE SOLVED: To enable an independent transmission of displayed word data without the synchronization with the reproduction timming of music data in transmitting music data and displayed word data from d center device. SOLUTION: A CPU 11 detects whether there is music data received from a center device 50 or not when the requirement of music data comes from a music reproduction circuit 17, and if the reception is made, a stop command is outputted to a music redroduction circuit 17. Next, when the requirement of displayed word data comes from a word display circuit 18, whether there is the displayed word data received from the center device 50 or not, and then if the reception is made, a stop command is outputted to the circuit 18. When a reference time to be measured corresponds to a time stamp in the displayed word data, based on the reference time outputted from a timmer 16, it is displayed as the displayed word data to a TV monitor 25. |
