IMAGE DATA TRANSMISSION SYSTEM, PROCESS AND PROGRAM, IMAGE DATA OUTPUT DEVICE AND IMAGE DISPLAY DEVICE
First Claim
1. A projector comprising:
- a keyword generating unit which generates a second keyword to be inputted to a computer;
a keyword determining unit which determines whether a first keyword matches the second keyword, when the first keyword is received from the computer;
a computer connection establishing unit which establishes connection to the computer when the keyword determining unit determines that the first keyword matches the second keyword; and
an image projecting unit which projects an image based on image data inputted from the computer, the image projecting unit visibly projecting the second keyword.

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 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.
