what worked well

  • 1. flexibility and reliability of DVTS system
  • 2. good video and sound quality
  • 3. acceptable time delay – ~ 2 sec
  • 4. effectiveness of the interactions
  • 5. excellent co-operativity and organisation
slide-16
SLIDE 16

problems and solutions

1. network – work with network engineers

  • reliability -
  • time delay – shorter links
  • Firewalls – dedicated links
  • audio quality / standardising audio volumes

2. security / patient confidentiality – need to

find VPNs that don’t degrade the image

3. PAL versus NTSC – need compatible video

mixing systems

SLIDE 17

what next ?

  • local / national interest is strong, but needs

developing

  • more links, better connections
  • how can we add value to the interactions
  • network protocol
  • more structured sessions
  • additional data / images / powerpoint
  • stop testing and start using – ‘mainstream’ the

technology

slide-18
SLIDE 18
  • linked curricula for education and research
  • live collaborative projects
  • disaster / pandemic management
  • linked databases, more integrated IT
  • public / population health
  • use of the technology across all sectors of

medicine, including in developing countries

what next ? medium term
