Abstract

PURPOSE: To simplify the change-over operation to the information network by receiving the channel CH selecting signal from TV receiver ultrasonic remote control transmission device and selecting the empty CH specified by the information network.
CONSTITUTION: The ultrasonic remote control receiver 13 is incorporated in the information network change-over device 12 and the selecting station signal from the ultrasonic remote control transmitter is received by the ultrasonic wave receiving microphone 15. the sound wave received by the microphone 15 is converted into the electric signal by the electroacoustic converter 16 and it is inputted to the signal discriminator 17. The discriminator 17 judges the input signal to be the same selcting station signal for changing-over to the space CH specified for network, according to this discriminating output, the relay 18 is operated, the change-over device is changed-over to the network side and the circuit connection to the information network is formed. Thus, the network change-over device 12 can be simply changed over by remote control.
