  Dr. Dmitry Vatolin
  Visicron Corp., USA
  
  We will show the following main technologies which allow videoconferencing over real Internet:
  
  
  1. Videocoding, optimized for conference "talking heads" and floating channels
  2. Audio technologies (Noise generation, voice activity detection, echo suppression and echo cancellation
  3. Transport technologies (working with NAT, SOCKs, Proxy, firewals)
  4. Server side technologies (clustering, multi-protocol support, servers architecture)
  
  Presentation includes the following demonstrations:
  
  
  • Videoconference in a university LAN (very good channel)
  • Videoconference through the server at a Moscow provider's site (good channel)
  • Videoconference through the server in USA (unpredictable channel)
  • Multiparty conference
  • Presentation through videoconference
  • Video broadcasting
