<P>PROBLEM TO BE SOLVED: To reduce standby power, prevent increase of answering time for operation of a GUI, and perform setting of a radio transmission communication channel of a video signal using a different radio transmission route. <P>SOLUTION: A first radio transmission route (5 GHz band) for video signal transmission and a second radio transmission route (2.4 GHz) for control signal transmission, connect between a media monitor 100 and a media box 200. A GUI (Graphical User Interface) application is installed in the media box 200, and the GUI is operated using a screen of a display panel 101 of the media monitor 100. The control signal for the GUI operation is carried through the second radio transmission route. At a standby time, only a communication module composing the second transmission route, is made to be a standby state, and standby power is reduced. The GUI control signal transmission can be done without trouble, and answering to the user operation is prevented to be slow. <P>COPYRIGHT: (C)2010,JPO&INPIT |
