Abstract

PURPOSE:To ensure a smooth and assured transmission of the necessary announcement information, by providing a switching mechanism connected to a timer plus an independent tuner to the terminal TV picture receiver on each line. CONSTITUTION:An originating device 13 of announcement information is connected to the main line cable 4 at the position near the antenna. The signal of announcement information is transmitted from the device 13 with a frequency that does not affect the frequency of the ordinary broadcast signal. Thus the announcement information is received at the TV picture receiver 6 for several minutes after power source supplies to the receiver 6 via an independent tuner 8 and the switching mechanism 9 incorporating a timer 7 provided to the receiver 6.
