As part of the Distributed Collaboratories project within the Distributed Systems Department at Lawrence Berkeley National Laboratory, we have designed, implemented, and deployed a camera control system and a conference controller that provide remote control capabilities for videoconferencing over the Internet. With these tools remote users can "walk" around the room focus in on objects, and actively participate in a videoconference rather than just observe.
The camera control system consists of a device server (devserv) and a client user interface (camclnt). The system allows users to pan, tilt, and zoom the cameras, switch between camera views, and get a picture-in-picture view from their desktops. The conference controller (confcntlr) allows conference participants to not only start and stop the media tools on a remote host, but also to dynamically change settings and turn transmission on and off. It supports the vic (video) and vat (audio) Internet videoconferencing tools and enhances their usability by providing an integrated and secure user interface for local and remote control of these applications.
