PROBLEM TO BE SOLVED: To solve the problem in which viewers in distant places have difficulty in looking at information such as small characters, diagrams and graphs in the case where the information desired to be shared with the viewers in a room is provided using a large screen display device such as a projector at lecture meetings, seminars, and the like.SOLUTION: Control of whether browsing at a plurality of information display terminals is enabled or not is made on the basis of whether mutual information communication can be performed between virtual network drivers between a client terminal storing data desired to be shared and a relay device. If browsing is enabled, the relay device adds an authentication key to an address for browsing and gives redirect notification to the information display terminals. Then, users of the information display terminals can browse data desired to be shared only if verification at the client terminal is a success.SELECTED DRAWING: Figure 11 |
