View Patent ↗Radio waves transmitted from the antenna of a broadcasting station are received by the antenna of a television receiver. The television receiver extracts an EPG from the received radio waves and transmits it to a remote controller via an infrared transmission/reception section. The remote controller displays the received EPG on a LCD and is then rendered in a state of waiting for selection of a program. If some program is selected and then a reserve button is manipulated, the remote controller transmits a control command for a recording reservation to a video tape recorder. The video tape recorder receives the control command with an infrared transmission/reception section, whereby the recording reservation of the designated program is set.
