Abstract:
1. A computer accessible non-transitory memory medium storing program instructions for performing a conference, wherein the program instructions are executable by a processor of a multipoint control unit (MCU) to implement: hosting a conference between a plurality of participants at respective participant locations, wherein the conference is performed using a plurality of endpoints at the respective participant locations; receiving audio from each of the plurality of endpoints; receiving audio level information from each of the plurality of endpoints; combining the audio from a plural subset of the plurality of endpoints to produce conference audio, wherein the audio from the plural subset is combined based on the audio level information, wherein the plural subset is less than all of the plurality of conferencing endpoints, wherein said combining comprises analyzing the audio level information from each of the plurality of endpoints to determine audio from a designated number (n) of videoconferencing endpoints which have highest audio levels, wherein the value of n is determined dynamically based on said analyzing, and wherein said combining the audio from the plural subset of the plurality of endpoints comprises combining only the audio from the n endpoints; and providing the conference audio to the plurality of endpoints.
