Card type network interface, network conference terminal device and network conference system

摘要

A wireless LAN conference system can be constructed without increasing the cost of equipment of a conference hall and without imposing a burden upon participants to execute a network setting. There are provided network conference terminal devices 11(2) to 11(n) in which network interface cards 1 are attached to information terminal devices. The network interface card 1 includes a connecting means for connecting the information terminal device to a wireless LAN, a determining means for determining whether the information terminal device is served as a host or a client of the wireless LAN, a setting means for requesting the host to transmit setting information necessary for executing the network setting to connect the information terminal device to the wireless LAN based on the fact that the information terminal device is determined as the client and executing the network setting by using the setting information transmitted from the host and a processing means for transmitting a requested setting information to the client based on the fact that the information terminal device is determined as the host and transmitting presentation data to the client in which the network setting was completed.
