transmitting the signal by causing visible light to blink according to the predetermined blinking pattern, from a projector disposed in an indoor space surrounded by a wall toward the wall; and
projecting video from the projector toward the wall,
wherein the visible light is reflected by the wall to prevent the signal from being received in an outside of the indoor space, and
the signal is used to transmit data related to the video projected to a terminal in the indoor space.
