Abstract: The present invention includes a method and a system providing balancing of work items required to be completed as a whole over the available computing systems in a video conference node cluster, in addition to providing sufficient redundancy among conference nodes by means of consistent hash functions.
Consistent hashing is based on mapping each object or work item to a point on a virtual circle. The system maps each available machine or node to many pseudo-randomly distributed points on the same circle.
The present invention can be used for example in monitoring calendar servers for scheduled video conferences and providing a user interface icon to endpoints participating in a scheduled video conference through which the endpoints enter the video conference, or monitoring dial-ins from an endpoint participating in a scheduled video conference and dialing out to the other endpoints participating in the scheduled video conference.

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.

Abstract: A method for managing media streams including at least video data and audio data in a multi-party video conference involving one or more groups of one or more nodes respectively receiving a media stream from each of a plurality of associated endpoints is provided. 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 endpoints is determined. An indication of the volume of the determined loudest audio and an identification of the node is transmitted to a decision maker. The highest received volume and the associated identification is determined. The node of the identification is instructed to transmit the received media stream of the endpoint to one of: all nodes in the one or more groups and to a proxy.

Abstract: The present invention relates to an image processing device and a method of framing changes and movements in a video image divided into N×N blocks of pixel positions. The method comprises calculating a first bitmap of the video image by a DCT transform on each of the N×N blocks of pixel positions, assigning a first binary value to the pixel positions of the N×N blocks when more than an amount of change, and a second binary value to the pixel positions of the N×N blocks when less than an amount of change. Calculating a third bitmap by an OR operation between a number of bitmaps representing past time frames of the video image, calculating a fourth bitmap by performing a dilation process of the third bitmap representing the current time frame of the video image, and creating one or more frames identifying area of changes and movements in the video image based on detecting BLOBs (Binary Large Objects) in the fourth bitmaps.
