Abstract

An adapter for providing network access to a shared image projection device may comprise a network interface for connecting to a network and receiving network data from a network device over the network. A client, operatively associated with the network interface, receives data from the network interface and produces a data signal. A video display driver, operatively associated with the client, receives the data signal and produces video data for the shared image projection device.

Claims

1. An adapter for providing network access to a shared image projection device, comprising:

a network interface for connecting to a network and receiving network data from a network device over the network;

a client, operatively associated with the network interface, said client receiving data from the network interface and producing a data signal; and

a video display driver, operatively associated with the client, for providing video data to the shared image projection device, said video display driver receiving the data signal produced by the client and producing said video data.

2. The adapter of claim 1, further comprising at least one computer readable storage media storing system configuration data, wherein said system configuration data allows the adapter to be identified on and accessed over the network.

3. The adapter of claim 2, further comprising display apparatus, said display apparatus displaying at least a portion of said system configuration data.

4. The adapter of claim 2, wherein said at least one computer readable storage media comprises a nonvolatile memory.

5. The adapter of claim 1, further comprising a server, said server allowing said adapter to host a meeting for which the shared image projection device is being used.

6. The adapter of claim 1, wherein said client comprises a T.120 client.

7. The adapter of claim 1, wherein the network data comprises a T.120 data packet within an 802.3 wrapper, wherein said network interface removes the 802.3 wrapper from the T.120 data packet, and wherein said client receives the T.120 data packet without the 802.3 wrapper.

8. The adapter of claim 1, further comprising a hang-up switch, said hang-up switch terminating a connection between a network device and said adapter when said hang-up switch is activated.

9. The adapter of claim 1, further comprising a status indicator, said status indicator indicating the status of said adapter.

10. The adapter of claim 1, wherein the adapter comprises the shared image projection device.

11. A method for providing network access to a shared image projection device, comprising:

connecting the shared image projection device to a network via a network adapter;

receiving network data at said network adapter, said network data being received from another device which is connected to the network; and

outputting video data from said network adapter to the shared image projection device, in response to the network data, whereby the network data is then displayed via the shared image projection device.

12. The method of claim 11, wherein the network data comprises a T.120 data packet within an 802.3 wrapper;

the method further comprising removing the 802.3 wrapper from the T.120 data packet after the network data is received by the network adapter.

13. The method of claim 11, further comprising setting system configuration data for said network adapter, said system configuration data allowing said network adapter to be identified on and accessed over the network.

14. The method of claim 13, further comprising displaying at least a portion of said system configuration data.

15. The method of claim 13, further comprising:

providing said network adapter with at least one computer readable storage media; and

storing said system configuration data within said at least one computer readable storage media.

16. The method of claim 11, further comprising registering said network adapter with a directory server.

17. A system, comprising:

a shared image projection device;

an adapter for providing network access to the shared image projection device, said adapter comprising;

a network interface for connecting to a network and receiving network data from a network device over the network;

a client, operatively associated with the network interface, said client receiving data from the network interface and producing a data signal; and

a video display driver, operatively associated with the client, for outputting video data to the shared image projection device, said video display driver receiving the data signal produced by the client and producing said video data.

18. The system of claim 17, further comprising:

a host computer for hosting a meeting for which the shared image projection device is being used; and

a configuration program operatively associated with said host computer and said adapter, said configuration program accessing said adapter to set system configuration data, said system configuration data allowing said adapter to be identified on and accessed over the network.

19. The system of claim 18, wherein said host computer comprises at least one computer readable storage media;

and wherein said configuration program comprises computer readable program code stored within the at least one computer readable storage media of said host computer.

20. The system of claim 18, wherein said adapter further comprises at least one computer readable storage media;

and wherein said system configuration data is stored within the at least one computer readable storage media of said adapter.

21. The system of claim 18, wherein said adapter further comprises a nonvolatile memory;

and wherein said system configuration data is stored within the nonvolatile memory of said adapter.

22. The system of claim 17, wherein said shared image projection device is a data projector.

23. The system of claim 17, wherein said adapter is housed within said shared image projection device.

24. A method for viewing information during a meeting, comprising:

coupling a data projector to a network of meeting participant computers via a network adapter; and

configuring the network adapter and meeting participant computers as peers in a virtual meeting.
