video conferencing
A discussion between two or more groups of
people who are in different places but can see and hear each
other using electronic communications. Pictures and sound are
carried by the telecommunication network and such conferences
can take place across the world.
To overcome the {bandwidth} and {latency} limitations of
current networks (especially the {PSTN}), some form of {video
compression} is often used.
