PROBLEM TO BE SOLVED: To allow a device displaying a video with a display device, if any, to share the video being displayed by the display device with a device newly connected to the display device, or the devices to have different menu items to inhibit the display of the video with the display device.SOLUTION: When terminal devices 2A and 2B are not connected with a projector 1, connecting the terminal device 2A to a projector 1 allows it to display a menu screen including an item for projecting a video. When a user selects the item, the projector 1 projects the video selected on the terminal device 2A. While the projector 1 is projecting the video, connecting the terminal device 2B to the projector 1 allows the terminal device 2B to display a menu screen including an item for sharing the video and an item for disconnecting communication. When the user selects the item, a video signal of the video being projected from the projector 1 is transmitted to the terminal device 2B, and the terminal device 2B displays the video of the transmitted video signal.SELECTED DRAWING: Figure 1 |
