Abstract

We present Vaudeville, a voice-activated,hands-free, ATM-based video conferencing application. This system isscalable; although video bandwidth is normally a limiting factor inthe number of conferences participants, the bandwidth attributed tothe video is not a function of conference size. This is achievedthrough an automatic, distributed floor control mechanism that givesthe appearance of an open floor. Audio and video are encoded inhardware using a platform-independent, ATM hardware multimediainterface. Vaudeville features digitally transmitted NTSC video,voice-activated audio transmission, audio bridging of two audiostreams, and voice-activated video switching. Multiple simultaneousmultiparty conferences are supported. Users can move freely amongconferences without knowledge of the underlying network structure. Wedescribe how Vaudeville was built using a component-based distributedprogramming environment. We also describe the algorithms used tocontrol the audio and video of the application.
