Peripherals • Maincamera(s) • Document Camera • Electronic Whiteboard • Everything you use during normal lessons
Transport medium • ISDN (90%)(connection oriented, reliable) • IP/LAN/WAN Internet (6%)(packet oriented, (no) bandwidth guarantied !!! • ATM Links (3%)(ideal but expensive)
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
Distance Education • Collaboration • Linkingclassrooms
Distance Learning in Transition Bring the World Into the classroom • Internet • Institutional LAN • CD-ROM • Universities • Student teams • Business • Outside experts
Access • Advanced placement • Dual enrollment • Diverse learning groups • Cross-cultural • Urban-suburban-rural • Intrastate-international • Special populations
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
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.
