摘要： With a conventional image-display system, a presenter sometimes has difficulty in providing every viewer with an easy-to-see picture.When projecting an image transmitted from a computer operated by the presenter and enabling the viewer to watch the image projected by the projector, the projector receives image data transmitted through two-way communication from the computer operated by the presenter, projects an image represented by the received image data and transmits the received image data to a client computer operated by the viewer through the two-way communication, and the client computer receives the image data transmitted through the two-way communication and displays the image represented by the received image data on its display.

摘要： 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 server 20 and projectors 301 through 30n, a communication command is issued according to UDP-based broadcasting to retrieve connectable projectors 301 through 303. Thereafter, the projector 301 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 20 and the projector 301. 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 301 by an outsider.

摘要： A system consisting of a plurality of terminals storing image data and an image displaying device which are connected with each other through a network capable of two-way communication has the disadvantage of decreasing in throughput on account of slow image data transfer over the network. The image displaying device performs two-way communications with each of the terminals by a communication means at the display device side. Also, the image displaying device acquires image data from a relevant terminal while instructing other terminals to suspend transmission by the image data acquisition controlling means, thereby suspending transmission of image data. The image displaying device displays images by the image displaying means based on the thus acquired image data.
