external input apparatus for example the set top box 300 then the control section 230 supplies the received operation signal to the remote control signal formation section 241 which forms a remote control signal corresponding to the received operation signal the remote control signal formation section 241 supplies the remote control signal through the output terminal 242 to the remote control signal transmission section 250 the remote control signal transmission section 250 then transmits the remote control signal as an infrared transmission in this manner the operation for the set top box 300 is sent as an infrared remote control signal to the set top box 300 if the signal from the reception processing section 212 is an operation signal for the base apparatus 200 itself then the control section 230 controls the pertaining components of the base apparatus 200 in accordance with the received operation signal consequently it is possible to change the channel selected by the tuner 202 or change over the signal output from the selector 206 on the other hand if the signal from the reception processing section 212 is an acquisition request for a website or a reception transmission request for electronic mail then the control section 230 controls the modem section 220 to establish a connection to the subscribed isp thereby connecting the base apparatus 200 to the internet consequently the base apparatus 200 can acquire information from a website and receive or transmit electronic mail in this manner the base apparatus 200 can receive select and demodulate a television broadcast signal receive and demodulate a video signal and or an audio signal from an external input apparatus supplied through the input terminals 204 and 205.
