A transmitter-receiver having a means for automatically determining the status of transmission medium such as optical fiber, and a means for automatically setting and resetting the transmission rate and/or output power according to the status of the transmission medium, a transmission loss and gain measurement method, and a transmitting-receiving system. A transmitter-receiver comprises at least: an output power controller for controlling the output power of a transmitter; an input power measuring section for measuring the strength of input signals; and an information processor for deriving the loss or gain of a path to change the output power of the transmitter and/or the rate of data transmission according to the derived loss or gain of the path. A transmission loss and gain measurement method applied to a system comprising transmission media and a plurality of the transmitter-receivers connected via the transmission media, comprises the steps of: transmitting information on the output power of a first transmitter-receiver from the first transmitter-receiver to a second transmitter-receiver; measuring reception strength by the second transmitter-receiver when the second transmitter-receiver receives the output power information; reading the output power information by the second transmitter-receiver; and comparing the reception strength with the output power information to calculate a transmission loss or gain by the second transmitter-receiver.

摘要:
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.
