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 translation: 公开了一种在多方视频会议中管理至少包括视频数据和音频数据的媒体流的方法和决策器。 视频会议涉及一个或多个节点的一个或多个组，分别从多个关联端点中的每一个接收媒体流。在一个或多个组中的每一个的一个或多个节点中的每一个中，媒体中最响亮的音频 确定从相应的多个相关联的端点接收的流。 此外，相应一个或多个组中的一个或多个节点中的每一个将确定的最大音频的音量和与最响亮音频相关联的节点的标识的指示发送到与每个一个或多个组相关联的相应决策器 。 在每个一个或多个决策者中，确定最高的接收量和相关联的识别。 接下来，描述制造者指示节点对应于最高确定卷的标识将与所确定的最响亮的音频相关联的端点的接收的媒体流传送到所述一个或多个组中的所有节点，或发送到与每个组相关联的相应代理 的一个或多个组。

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.
