The display computer and projectors. The audio capture computer and sound system. The control computer which provides a software interface to the sound system. The capture computers capture and encode local video and audio and send it out over the Grid to remote sites. The display computer receives video from the Grid, decodes it and projects it to a screen through the projectors.
Remote audio is handled by the audio capture computer.
Since the goal of the Access Grid is to provide group to group communication, large spaces come into picture. Large spaces have acoustic peculiarities which causes echo and other related problems. The sound system corrects these before the audio is sent out. The node at UKy came into being in the summer of 1999. It was built from four Pentuim III Xeon based dual processor Dell Computers.
