Specifically, firstly, the volume video information is transmitted to a projection device at a different place through a pre-deployed communication port, and then the projection device at the different place is released to a display area preset at the different place according to a corresponding release demand. It is understood that the specific form of the display area preset at the different place may also include: projection cloth, projection board and wall.
