Teaching and Exchanging experiences via examples is getting more and more popular
Two basic independent ways:- Sharing data (video,PDF,etc.) via Internet (MedFaculties + CESNET)
MedFaculties – provide the content CESNET provides the infrastructure and control softwareStable application dedicated to students
-Live Surgery transmissions (CESNET + Clinics)
Live Surgeries are requested on medical congresses, annual conferences, etc.usually organized in attractive environments as Spa resorts, famous building in historical towns, concert halls, etc. with no or very weak connectivity !
Main problem: Nearly each event needs special preparation and extra cost. There are several tools which can be used
1) H323 videoconference units(0,5 - 6 Mbps with compression)
2) DVTS (35 Mbps)
3) MVTP-4K (1,5 – 10 Gbps)
(codec – high compressionLow quality of coloures and grey scale, high latency)
Software, no compression, no internal latencyQuality defined by the camera
FullHD quality, no compression, No internal latency, up to 8 channels, 3D

Interesting events in 2012
- Usually in the places where is no good network-There are other limitations as big halls-The attendees expect some form of show
Always big challenge for organizers

Initial phase: Simple projector + expensive active glasses
Next step
a) Strong projectors + cheap passive glasses - expensiveb) Projector + PM to cheap passive glasses - contrast problems
New trends with new and cheap technology
3D TV displays (Panasonic, Samsung, LG) + glasses (active or passive) – cheap, very good resolution,Ideal for small labs and professional education
Where to go for congresses and symposia ?
Back to 2D ?

Thank you for attention
