Problems solved by technology

In traditional signaling protocols, when there is a change in conference state, for example, if P1 disables its video, an informative message for all participants P1 to P10 used to be sent; this poses a serious scalability problem

example

[0461] Example: Subscriber A at POTS1 calls subscriber B at ViPrV1. The following sequence of events occurs:

[0462] 1. UD1 (Mediatrics or any unicast device) receives a request from User_A to connect to User_B.

[0463] 2. UD1 sends an invitation to UAM. The To field or display name in the invitation identifies that the call is for User_B.

[0464] 3. The UAM receives the invitation as an incoming call C1.

[0465] 4. UAM extracts User_B's sip address from the invitation on C1 and initiates a call to C2 to this user by sending an invitation to V1.

[0466] 5. The UAM also cross-connects C1 to C2.

[0467] 6. V1 sees an incoming INVITE from UAM, which is recognized by the SDP as a ViPr class device. Therefore, the software on V1 knows that the peer software can support all the functionality that a ViPr device is expected to have (including replacement / review etc.).

[0468] 7. User_B, eg at V1, replies OK to the invitation.

[0469] 8. The UAM marks the connection C2 a...

Abstract

The invention provides a teleconference system including a network. The system includes a plurality of nodes that communicate with each other to form a conference. Each node has a video display with a display layout, at least one of the nodes individually at least partially controls the display layout of each node in the conference, the display layout has specific parameters that can be unique to each node. Format. The present invention provides a method for providing a conference call comprising the steps of forming a conference using a plurality of nodes communicating with each other over a network. Each node has a video display with a display layout. There is the step of using at least one of the nodes to individually at least partially control a display layout of each node in the conference, the display layout having a specific format that can be unique to each node. The invention provides a conference call node. The invention provides a teleconference system including a network. The system includes a plurality of nodes that communicate with each other over a network to form a conference. When a change occurs, each node simply communicates the change to the other nodes. A method for teleconferencing between at least three parties includes the step of establishing a conference between said parties. There is a step of making changes to the meeting. There is only the step of communicating said changes to the participating parties.
