20140317725 | IMAGE DATA TRANSMISSION SYSTEM, PROCESS AND PROGRAM, IMAGE DATA OUTPUT DEVICE AND IMAGE DISPLAY DEVICE - When a connection is established between a server and projectors through, a communication command is issued according to UDP-based broadcasting to retrieve connectable projectors through. Thereafter, the projector to 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 server and 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 projector by an outsider. | 10-23-2014 |
