Abstract
In one embodiment, a system includes a video mixer coupled with an audio mixer for exchange of information that includes a first set of delay values respecting input audio streams received by the audio mixer from a plurality of source endpoints, and output audio streams sent from the audio mixer to a plurality of destination endpoints. The information further including a second set of delay values respecting the corresponding input video streams. The audio mixer calculates end-to-end video delays, and the video mixer calculates end-to-end audio delays. The audio mixer delays the output audio streams to equalize the end-to-end audio and video delays in the event that the end-to-end audio delays are less than the end-to-end video delays, and the video mixer delays the output video streams to equalize the end-to-end audio and video delays in the event that the end-to-end video delays are less than the end-to-end audio delays.
