Online video conferencing

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:

  1. Video conferenced discussions
    • 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.
  2. Web casting
    • One video is steamed to many viewers, such as in Internet broadcasts of parliamentary committees.
    • Questions to the speaker come back though another channel, perhaps by typing them into IRC or a chat room.
  3. Video conferenced e-meetings
    • The main speaker is broadcast to others, who see the speaker and/or his presentation slides.
    • Questions come back via video, audio or text, all integrated in the same software.
