CONSTITUTION:A signal from a central processing unit 10 is transmitted to computers 2, 5a, 5b, 5c. A data signal at the CPU12 and an RF signal on a television common viewing line are modulated/demodulated by a MODEM14, message information transmitted from the MODEM14 is mixed with a television signal 21 at a mixer 20 and the result is transmitted to television common viewing lines 22a, 22b. A reception terminal of a television receiver 31 is connected to a terminal device 32 by a cable in each guest room 30 and a television broadcast signal and a data signal are separated at the terminal device 32. Then the data signal is transmitted to a control section 37 via a MODEM36 and the presence of message is displayed on an operating section 39 by using a signal from the control section 37. |
