A TV microcomputer sends a channel switching demand command to a wireless center microcomputer, via an SS transmission/reception unit and an SS transmission/reception unit. Via the SS transmission/reception unit and the SS transmission/reception unit, the wireless center microcomputer returns, to the TV microcomputer, a response indicating that the command demanding the channel selection has been received. Subsequently, the wireless center microcomputer performs a process demanded by the received channel switching demand, and sends, to the TV microcomputer, process completion information indicating that the process has been performed. Receiving the process completion information, a TV main body performs muting of the screen for a certain period starting from the reception of the information, so as to hide the visual disturbance on account of the delay at the time of the channel switching.
