In a digital TV broadcast signal receiving system, an outdoor appliance comprises a tuner for receiving a TV broadcast signal transmitted from a TV tower or a broadcast satellite, a signal demodulator for demodulating the TV broadcast signal, and a first wireless interface for transmitting data with a second wireless interface provided in an indoor appliance. The indoor appliance further has a signal decoder for separating an audio signal and a visual signal and outputs them to a monitor apparatus. An appliance such as a personal computer having no tuner circuit can receive the TV broadcast signal if it has a wireless interface such as a wireless LAN. Furthermore, the data communication between the outdoor appliance and the indoor appliance is performed by wireless interfaces, so that a cable connecting between an outdoor appliance and an indoor appliance can be omitted.
