Video conferencing
From E-Consultation Guide
It is possible to compess video recordings and send the files across the Internet. This is the technology behind the online video download sites, like YouTube.
Small images can be streamed in real time, as they are recorded. There are three communications situations:
Video conferenced chats
- Everyone has a microphone, speakers or earphones and a web cam.
- They can see small images of everyone else, as shown in the screenshot on the right.
- They take turns to speak, discussing a topic among a small group.
- Consultation applications:
- Online focus groups with illiterates.
- Discussions with key stakeholders who cannot meet in the same place.
