    摘要： Systems and methods for managing virtual collaboration systems are disclosed herein. A virtual collaboration system includes a hoster configured to receive second media streams from at least a second node, and to transmit those streams from at least one simulated node to at least a first node; and a management subsystem adapted to dynamically configure a topology of a virtual collaborative event, wherein configuration of the topology includes a determination of media stream connections among the at least one simulated node and the at least a first node based on at least one policy, and wherein the media stream connections establish and maintain virtual relationships among the at least one simulated node and the at least a first node.

    摘要： The present invention is embodied in a computer-readable program in a computer-readable medium for upgrading a video conference system, the computer-readable program comprising acoustic echo canceling control software having an application programming interface. The acoustic echo canceling control software is implemented on a computer system that operates the video conference system and macros are configured to couple the acoustic echo canceling control software to hardware components of the video conference system and to interface with the application programming interface. The macros are user configurable for providing real time adjustments of echo canceling runtime parameters of the hardware components during a video conference session.

    摘要： The present invention is embodied in an audio conferencing system for a computer system, including a database storing a plurality of mode definitions each indicative of a video conference session configuration (402) and an acoustic canceling subsystem operating on the computer system having an initial configuration running during a video conferencing session (406). An acoustic change to a new acoustic configuration of the video conferencing system is detected during the session (408), a mode definition is selected from the database based upon the new acoustic configuration and the echo canceling system is dynamically reconfigured based upon the new acoustic configuration during the session (410).
