Abstract
There has been a problem of necessitating a complicated work for establishing a connection capable of intercommunication between a computer as server and a projector as client. When a connection is established between a serverand projectorsthrough, a communication command is issued according to UDP-based broadcasting to retrieve connectable projectorsthrough. Thereafter, the projectorto be connected is selected and is assigned an IP address to establish the connection. In this manner, a user can easily obtain a connection environment capable of intercommunication between the serverand the projector. A TCP/IP communication command is used to input or output image data, ensuring reliable transmission. Since the authentication can be provided using a keyword projected during the connection establishment, it is possible to prevent an unauthorized access to the projectorby an outsider.
