own video stream, every person can watch the same stream, as if it
were a TV broadcast. This reduces the strain on the network consid-
erably, even if 5 or 10 channels are available. This technique can be
used with either stored or live video feeds, and can also be used to
combine live and stored video together, so that MPEG video can be
watched "live" or paused and replayed.
