Network system of projector
First Claim
1. A network system, comprising:
- an information terminal apparatus; and
a projector that projects image data on a projector screen and is connectable to the information terminal apparatus via a network, whereinthe information terminal apparatus includes;
a host information terminal apparatus that supplies the image data to the projector by employing a LAN, anda plurality of client information terminal apparatus other than the host information terminal apparatus that receive the image data and display the image data on a display other than the projector screen,wherein when a network connection between the information terminal apparatus and the projector is established, the image data is commonly shared between the host information terminal apparatus and the plurality of client information terminal apparatus and the plurality of client information terminal apparatus and the host information terminal apparatus are structured such that they are selectively used for displaying and manipulating the image data, andwherein the plurality of client information terminal apparatus is configured to access, via the network, and display image data that has not been projected by the projector, and that is stored on the host information terminal apparatus.

Abstract
A network system of a projector is provided in which a network connection is established between a plurality of information terminal apparatus and the projector, and an image data file owned by an information terminal apparatus can be commonly used. A network system of a projector is arranged by an information terminal apparatus and a projector connectable to the information terminal apparatus via a network. The information terminal apparatus is arranged by a personal computer which supplies image data to the projector, and personal computers which are connected to this personal computer by a wireless manner. When the network connection is established between the personal computer and the projector, and when the network connection between the personal computer and the personal computers is established, the image data is commonly used among these personal computers.
