ABSTRACT:
Voluntary information transmitting apparatus in a wired television system comprises an information signal generator which generates a guide information signal at an ordinary time and an alarm information signal in an emergency, and a control signal generator which generates in the emergency a control signal for causing each television receiver to pick out the alarm information signal. The information and control signals generated by the generators and a television broadcast signal are mixed and transmitted to the television receiver of each subscriber. The television receiver is equipped with a remote control unit, so that the alarm information signal can be automatically received in the emergency. The information signals are transmitted as signals having the same frequency band as that of the television broadcast signal, so that the transmitting circuit of the system requires no special electric equipment.
