Abstract: A display method of a display device connected to a plurality of terminals via a network, the display device displaying one or more split window areas, comprising: receiving identification information and a display request of a terminal among the terminals from the terminal, determining whether or not the terminal is permitted to connect to the display device and whether or not the terminal is permitted to display to the display device, and displaying, when the terminal is a terminal permitted to display, a multi-window screen that is synthesized based on image data and predetermined information received from the terminal.

Abstract: A technique for presenting display screens of a plurality terminals connected to a network on a multi-window screen of a display screen of a display device. A communication unit receives image data captured and then sent by each terminal having a screen capture function. A display control unit controls an image synthesizer to synthesize the captured image data into single screen multi-window format data. A multi-window screen is thus presented.

Abstract: A projector that projects images includes a projection display module by which the projector projects the images, a network interface by which the projector can communicate with a network, and a web server module coupled to the network interface and to the projection display module. The web server module, in response to a request to provide a working status of the projection display module received through the network interface from a client over the network, sends working status information representing the working status through the network interface to the client over the network. The web server module also, in response to control information received through the network interface from the client over the network in response to the sent working status information, controls the working status by sending a control signal to the projection display module based on the control information.

Abstract: A method includes sending image related working status information representing image-related working status of a projector that projects images, to a client over a network in response to a request to provide the image-related working status of the projector. The image-related working status is related to display characteristic of the projected image. The method includes controlling the image-related working status of the projector based on the control information received from the client over the network in response to the sent image-related working status information. The image-related working status information is sent to the client with screen information from which the client can display a user interface that includes the image-related working status information.
