<P>PROBLEM TO BE SOLVED: To prevent the output control of AV (Audio Visual) signals from being obstructed by making a radio power transmitter determine that supply power to a power receiving side device which receives power by radio transmission has become insufficient for the operation of the device. <P>SOLUTION: A radio transmission unit 100 includes a radio power transmission part 103 for radio-transmitting the power to a display 200 and an electric energy detection part 102 for detecting electric energy to be radio-transmitted. An AV signal radio transmission part 109 radio-transmits the AV signals of contents to the AV signal radio reception part 204 of the display 200. A comparison/control part 104 compares an electric energy detection value obtained from the electric energy detection part 102 with a threshold. The comparison/control part 104 determines that the supply power to the display 200 is insufficient when the electric energy detection value exceeds the threshold, makes the AV signals be recorded in an AV signal recorder 108, and executes the control of performing reproduction and outputting the AV signals when the electric energy detection value becomes equal to or smaller than the threshold. <P>COPYRIGHT: (C)2012,JPO&INPIT |
