Abstract: A control unit and a method for a video conferencing system, the method performed by a control unit in a video conferencing system during an ongoing video conference, comprising a plurality of endpoints, comprising receiving at least one input media stream from at least one endpoint, detecting a first pointer event in the at least one input media stream, providing a first graphical item associated with the first pointer event, encoding the first graphical item in an output media stream, transmitting the output media stream to the at least one endpoint, detecting a second pointer event in the at least one input media stream from the at least one endpoint, and perform an action associated with the second pointer event, where one of a group consisting of a first and second pointer event includes one of a group consisting of a light signal, a gesture, and a sound signal.

Abstract: Load balancing in a multimedia conference is disclosed, involving one or more internal terminals (Terminal 3) and one or more internal nodes (Node B) separated from one or more external terminals (Terminal 1, Terminal 2) and one or more external nodes (Node A) by a firewall. Media data from at least one of said terminals received at at least a first one of said nodes are forwarded through the firewall to at least a second one of the nodes, and received media data at the at least a second one of said nodes are processed by the second one of the nodes. At a first event, reconfiguration is performed of said first one of said nodes to process received media data and of said second one of said nodes to forward received media data to said first one of said nodes. At a second event, loading is done of at least a part of said received media data being processed at the first one or second one of said nodes to at least a third one of said nodes.
