| A
videoconference
or video
conference (also known
as a videoteleconference) is a set of
interactive telecommunication technologies
which allow two or more locations to interact
via two-way video and audio transmissions
simultaneously. It has also been called
'visual collaboration' and is a type of
groupware.
Videoconferencing differs
from videophone calls in that it's designed
to serve a conference rather than individuals.
It is an intermediate form of videotelephony,
first deployed commercially by AT&Tduring
the early 1970s using their Picturephone
technology.
