PURPOSE:To make it possible for users to view a wire TV broadcast at their request for pay by making it possible to view a desired channel through a TV receiver by operating trap unit by a controller and then by leading wire TV signals to a tuner. CONSTITUTION:As well as a standard TV broadcast signal received by antenna 1, mixer 3 receives the signal of a wire broadcast unit that has frequency spectrums similar to those of a standard TV broadcast and a frequency outside the standard TV broadcast band and then mixes them mutually to transmit the output to each room through distributor 4. On the other hand, in case that the reception of the specific channel of a wire TV broadcast is desired in each room in addition to the standard TV broadcast, trap unit 7 is put into operation by controller 5 such as a coin timer and wire TV signals are led to tuner 8 to view a desired channel through TV receiver 16. Consequently, wire TV broadcasts can be viewed at any time for pay at user's request. |
