Abstract: A method and a decision maker for managing media streams comprising at least video data and audio data in a multi- party video conference are disclosed. The video conference involves one or more groups of one or more nodes respectively receiving a media stream from each of a plurality of associated endpoints.In each of the one or more nodes of each of the one or more groups, the loudest audio of the media streams received from the respective plurality of associated end points is determined. Further, each of the one or more nodes of the respective one or more groups transmits an indication of the volume of the determined loudest audio and an identification of the node associated with the loudest audio to a respective decision maker associated with each one or more groups. In each one or more decision maker, the highest received volume and the associated identification is determined. Next, a descicion maker instructs the node of the identification corresponding to the highest determined volume to transmit the received media stream of the endpoint associated with the determined loudest audio to all nodes in the one or more groups, or to a respective proxy associated with each of the one or more groups.

Abstract: A method and a device providing one virtual endpoint dedicated to serve one particular real endpoint, and the virtual endpoint is typically installed on a server in the same local network as the associated real endpoint, where an MCU or a fraction of a distributed MCU also is installed. In the upstream direction, the virtual endpoint includes at least an upstream decoder, a scaling unit and an upstream encoder. In the downstream direction, the virtual endpoint includes at least a number of decoders, a composing unit and a downstream encoder.
