  1. Agenda VTEL Company Infos Videoconferencing Basics Applications Live Demo

  2. VTEL Corporation • 25,000 installed systems • Customers in 61 countries • 26 VTEL offices • 740 employees • $ 160 Million Sales

  3. Full Line of Packaged Systems Personal Settop Workgroup Enterprise Simple User Interfaces Network Management Interoperability

  4. User Interfaces There is no „The interface for everybody“ !!!!

  5. Position of VC in the DE segment

  6. What do you need to do it ? • Videoconferencing systems • Peripherals • Reliable transport medium

  7. Videoconferencing System • Easy to use • Reliable • High Quality • 3 Media: Audio, Video and Data • Dual Monitor • PC based • LAN, WEB Access

  8. Peripherals • Maincamera(s) • Document Camera • Electronic Whiteboard • Everything you use during normal lessons

  9. Transport medium • ISDN (90%)(connection oriented, reliable) • IP/LAN/WAN Internet (6%)(packet oriented, (no) bandwidth guarantied !!! • ATM Links (3%)(ideal but expensive)

  10. Bandwidth requirement • ISDN (min. for prof. quality) • 384 kBit/s (6B channels) • 30 fps, 7 kHz Audio • LAN / IP • 1 Mbit/s Bandwidth guarantied • 30 fps, 7 kHz Audio

  11. Distance Education • Collaboration • Linkingclassrooms

  12. Distance Learning in Transition Bring the World Into the classroom • Internet • Institutional LAN • CD-ROM • Universities • Student teams • Business • Outside experts

  13. Access • Advanced placement • Dual enrollment • Diverse learning groups • Cross-cultural • Urban-suburban-rural • Intrastate-international • Special populations

  14. Education and Training of today- New Model • Bring the World Into the Classroom • Internet • Organizational LAN • Universities • Working teams • Business • Outside experts • Satellite System • Audio graphics

  15. VC and Streaming Video • Important is the combination • Linking some classrooms with traditional VC • Enable other (unlimited) to be also in the same lesson as listener from home office or any other location • Enable the students to review any lesson at a later time.

  16. VC and Streaming Video Appl.

  17. Streaming Video User View
