Abstract:
1. An apparatus for performing distributed video conferencing, comprising: a media switch operable to communicate with an audio bridge that is operable to receive audio data from a first and a second end point for a conference call, wherein the media switch can also communicate with a video bridge operable to receive video data from the first and second end points, and wherein an input-to-output mapping is determined for each input audio output stream from the end points to a mixed audio stream, whereby the mapping can be communicated to the video bridge that can receive one or more video streams and delay each of the video streams such that the mapping may be reproduced, and wherein the video streams that are arriving at a latest time are identified and all of the other video streams are delayed such that an input-to-output matching of each individual video stream is matched to the mapping of a corresponding audio stream.
