ABSTRACT In this paper, we describe the design and implementation of a prototype software video production switcher, vps, that improves the quality of the content of MBone broadcasts. vps is modeled after the broadcast television industry's studio production switcher. It provides special effects processing to incorporate audience discussions, add titles and other information, and integrate stored videos into the presentation. vps is structured to work with other MBone conferencing tools. The ultimate goal is to automate the production of MBone broadcasts.
