US 2004/0006648 A9 · Card type network interface, network conference terminal device and network conference system

Abstract

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.

Dependent claims

A card type network interface which can be attached to an information terminal device, comprising:

connecting means for connecting said information terminal device to a local area network;
and
setting means for requesting a host of said local area network to transmit setting information necessary for executing a network setting to connect said information terminal device to said local area network based on the fact that said card type network interface can be attached to said information terminal device and executing said network setting by using said setting information transmitted from said host.

A network conference terminal device in which a card type network interface is attached to an information terminal device and which includes presentation processing means for displaying and controlling presentation data according to the need, said card type network interface including:

connecting means for connecting said information terminal device to a wireless local area network;
and
setting means for requesting a host of said wireless local area network to transmit setting information necessary for executing a network setting to connect said information terminal device to said wireless local area network based on the fact that said card type network interface is attached to said information terminal device and executing said network setting by using said setting information transmitted from said host.

A network conference system comprising:

a host of a wireless local area network;
a client of said wireless local area network, wherein said includes an information terminal device to which a card type network interface is attached and presentation processing means for displaying and controlling presentation data according to the need, said card type network interface includes connecting means for connecting said information terminal device to said wireless local area network and setting means for requesting said host to transmit setting information necessary for executing a network setting to connect said information terminal device to said wireless local area network based on the fact that said card type network interface is attached to said information terminal device and executing said network setting by using said setting information transmitted from said host and said host transmits said setting information to said client based on a request of said setting information and transmits said presentation data to said client in which said network setting was completed.

A network conference system comprising an image display device and a client of a wireless local area network, wherein said image display device has an information terminal device to which a card type network interface can be attached, said information terminal device has said card type network interface attached thereto and includes a presentation processing means for displaying and controlling presentation data;

said client is constructed such that said card type network interface is attached to an information terminal device and includes said presentation processing means according to the need;
said card type network interface comprising:
connecting means for connecting said information terminal device to said wireless local area network;
determining means for determining based on the fact that said card type network interface is attached to said information terminal device whether said information terminal device is served as a host or a client of said wireless local area network;
setting means for requesting said host to transmit setting information necessary for executing a network setting to connect said information terminal device to said wireless local area network based on the fact that said information terminal device is determined as said client by said determining means and executes said network setting by using said setting information transmitted from said host;
processing means for transmitting said requested setting information to said client based on the fact that said information terminal device is determined as said host by said determining means and transmitting said presentation data to said client in which said network setting was completed;
processing means for requesting said host to get a presentation right based on the fact that said information terminal device is determined as said client by said determining means, said network setting was completed by said setting means and that a predetermined operation is executed by said information terminal device and transmitting said presentation data to said host and said client based on the fact that said presentation right is obtained;
and
processing means for allowing said client to get said presentation right based on the fact that said information terminal device is determined as said host by said determining means and that said host is requested to get said presentation right, and said image display device is constructed such that said information terminal device attached to said image display device is determined as a host by said determining means.
