In this paper, we describe the design and implementation of a software video production
switcher, vps, that improves the quality 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.
