Zusammenfassung:	PURPOSE: To control a receiving side device in a character broadcasting system by including a device control code in a character broadcasting wave. CONSTITUTION: A device control code is added to a broadcasting wave including a character signal code for character broadcasting. The broadcasting wave is sent to a character signal decoder 30 through a receiving circuit 20. The device control code is decoded by a device control code decoding part 30a in the decoder 30 and the decoded result is applied to a device 32 through a device control circuit 31. The device 32 is controlled based upon the device control code. A bidirectional communication system can be established by transmitting a signal processed by the device 32 from the receiving side through a telephone line 52 or the like. When a storage device is connected to the device 32, received character broadcast can be stored in the storage device and then reproduced.
