Multimedia Communication The new? medium for Collaboration,Learning

Video Conferencing “ VC ” “Video Telephone” for collaborators, teachers ??

Video Technologies (for ISC) 5 VC Technology  Real-time, two-way, audio and video “video telephone”“video telephone” Small group collaborationSmall group collaboration  Maturing technology Around for 15+ years - from broadcast TV Around for 15+ years - from broadcast TV Historically expensive Historically expensive Limited general use; only long distance applicationLimited general use; only long distance application … the internet is changing this rapidly!

Video Technologies (for ISC) 6 VC History  Closed Broadcast TV – special circuits  Telephone links – low quality  H video over Digital phone lines Dedicated circuits (bandwidth) Dedicated circuits (bandwidth) ISDN Access: x6 lines (768Kbps) ~$350/mo ISDN Access: x6 lines (768Kbps) ~$350/mo User pays for long distance time User pays for long distance time

Video Technologies (for ISC) 7 VC & the internet  H video over packet (IP) networks Limitations: Limitations: Packetization overhead – delaysPacketization overhead – delays “available” bandwidth – quality impact if congested“available” bandwidth – quality impact if congested Advantages Advantages Ubiquitous(?) connectivityUbiquitous(?) connectivity Cost: … just part of the data trafficCost: … just part of the data traffic Supported by all commercial VC product

Video Technologies (for ISC) 8 VC Applications High Quality  Appliance System Polycom; Tandberg Polycom; Tandberg  Room installation - costs  Small/medium groups  Quality Required Higher Resolution Higher Resolution Faster Action Faster Action Near TV quality Near TV quality  Higher QOS on network New high res apps e.g. view into lab (OR) … Low Cost  PC-based Windows Messenger  Office location - no cost!  Single Participant per end  Accept less quality Low resolution  Low bandwidth.. But cameras and network bandwidth are improving
