Abstract

A teleconferencing system includes a network. The system includes a plurality of nodes in communication with each other to form a conference. Each node having a video display with a display layout, at least one of the nodes individually controlling at least partially the display layout of each node in the conference with a specific format able to be unique for each node. A method for providing a teleconference including the steps of forming a conference with a plurality of nodes in communication with each other through a network. Each node having a video display with a display layout. There is the step of controlling individually with at least one of the nodes at least partially the display layout of each node in the conference with a specific format able to be unique for each node. A teleconferencing node. A teleconferencing system includes a network. The system includes a plurality of nodes in communication with each other through the network to form a conference. Each node communicating only a change to the other nodes when the change occurs. A method for conducting a telecommunications conference between at least three parties includes the steps of establishing a conference between the party. There is the step of making a change to the conference. There is the step of communicating only the change to the parties.

Claims

1. A teleconferencing system comprising:

a network; and

a plurality of nodes in communication with each other to form a conference of live scenes at each node, each node having a video display with a display layout, at least one of the nodes individually controlling at least partially the display layout of each node in the conference with a specific format able to be unique for each node.

2. A system as described in claim 1 wherein each node is forced to display video in the specific format.

3. A system as described in claim 2 wherein each node is locked into the specific format.

4. A system as described in claim 3 wherein each node is forced to display certain video streams from the other nodes of the conference at specific locations on the display.

5. A system as described in claim 4 wherein each node controls what is displayed on any portion of the screen not controlled by the one of the nodes.

6. A system as described in claim 5 wherein the one of the nodes completely controls the display layout of each node.

7. A method for providing a teleconference comprising the steps of:

forming a conference with a plurality of nodes in communication with each other through a network of live scenes at each node, each node having a video display with a display layout; and

controlling individually with at least one of the nodes at least partially the display layout of each node in the conference with a specific format able to be unique for each node.

8. A teleconferencing node for a network with other nodes comprising:

a network interface which communicates with the other nodes to form a conference of live scenes at each node; and

a controller individually controlling at least partially the display layout of each node in the conference with a specific format able to be unique for each node.

9. A method for conducting a telecommunications conference between at least three nodes comprising the steps of:

establishing a conference between the nodes of live scenes at each node;

making a change to the conference; and

communicating only the change to the nodes.

10. A method as described in claim 9 wherein the communicating step includes the step of communicating only the change only to the nodes affected by the change.

11. A method as described in claim 10 wherein the making step includes the step of making the change to one of the nodes'"'"' status.

12. A method as described in claim 11 wherein the making step includes the step of making the change to the conference'"'"'s state.

13. A method as described in claim 12 including the step of sending a directed message from one of the nodes to only certain of but less than all of the parties.

14. A method as described in claim 13 wherein the establishing step includes the step of establishing the conference based on SIP NOTIFY/OK techniques.

15. A teleconferencing system comprising:

a network; and

a plurality of nodes in communication with each other through the network to form a conference of live scenes at each node, each node communicating only a change to the other nodes when the change occurs.

16. A system as described in claim 15 wherein each node communicates only the change only to the nodes affected by the change.

17. A system as described in claim 16 wherein the change to the conference includes a change to one of the nodes'"'"' status.

18. A system as described in claim 17 wherein the change to the conference includes a change to the conference'"'"'s state.

19. A system as described in claim 18 wherein one of the nodes sends a directed message to only certain of but less than all of the nodes.

20. A system as described in claim 19 wherein the plurality of nodes establishes the conference based on SIP NOTIFY/OK techniques.

21. A system as described in claim 20 wherein each node has a controller and a Network Interface in communication with the controller and the network, the controller effecting any change to its node and sending the change through the network interface to through the network to the other nodes of the conference.

22. A teleconferencing node for a network with other nodes comprising:

a network interface which communicates with the other nodes to form a live conference of live scenes at each node; and

a controller which communicates only a change to the other nodes when the change occurs.
