Contents-delivery system, contents-transmission device, contents-reception device, and contents-delivery method

摘要

A contents-delivery system has a contents-transmission device transmitting the contents, and a contents-reception device receiving the contents from the transmission device. A first communication device performs communication from the transmission device to the reception device via a high-directivity transmission carrier. A second communication device performs communication at least from the reception device to the transmission device. An optical position confirmation device permits it through optical irradiation to confirm that a position of the reception device with respect to the transmission device is within a range in which the first communication device can communicate. A position of the reception device is matched with the transmission device based on an irradiation position of visible light. It is thus possible to locate the reception device to a communication-enabled position if the reception device is directed against the transmission device.
