Video conferencing is the process of using a camera and microphone to send images and sound across a network in real time. This allows two or more people to communicate and collaborate; to share lessons; discuss ideas and hear foreign languages from native speakers in their home countries. It is possible to use the same process, with just a microphone and speakers to create audio conferences.

This site contains some example recorded conferences. Once you have seen what video conferencing is like, and are interested in moving it forward, a good next step is to talk to your Local Authority to get hands-on experience with using equipment "live".
