Here is a screencast explaining how the Three "Camera" Webcast from the SLN Summit was performed. http://pilot.sln.suny.edu/documentation/ANGEL/webcasting/webcasting.htm I will note here that many of the presenters wanted to use their own comptuers and did not have S-Video Out, so many of the presentations were a two camera shoot.

Configuration Overview

An excellent job done. A scheme diagram of the configuration would be nice. http://www.gliffy.com/ James/Eurominuteman

Audio Echo Behavior during a Workshop

Submitted by Eurominuteman on Sun, 2008-02-10 19:43.

Wiki makes a recommendation to this problem: 

"One of the most direct uses of equalization is at a live event, where microphones and speakers operate simultaneously. An equalizer is used to ensure that there are no frequency bands where there is a round trip gain of greater than 1, as these are heard as audible feedback. Those frequencies are cut at the equalizer to prevent this."

This is somthing I really need to look into.

I will be bstreamcasting a live event using Ustream in a couple of weeks, where I am going to have this problem.  Anyone have any step by steps with a particular euqalizer that they know works?
