PROBLEM TO BE SOLVED: To eliminate the need for preparing information processing devices software to control switching of video data to be transferred to a video display device in a video transfer system which transfers video data from a plurality of information processing devices to the video display device, as well as to enable switching of video data to be accomplished by a simple operation.SOLUTION: In the diagram on the upper side, only a radio transmitter with device ID=2 transmits video data, and a radio receiver transfers video data to a projector from an information processing device connected to the radio transmitter. The diagram on the lower side shows a state in which a radio transmitter with device ID=3 has started sending video data from the state in the diagram on the upper side. Since the radio transmitter with device ID=2 is not locked in a transfer state, the radio receiver switches the transmission source for the video data to be transferred to the projector from the radio transmitter with device ID=2 to the radio transmitter with device ID=3. |
