video conferencing? Video conferencing uses video and audio systems to bring groups
from different geographic locations together for a meeting or class.
Video conferencing technology allows participants to communicate
verbally, electronically and visually. Participants can share documents,
computer-displayed information and whiteboards.
How do they work? Participants gather in one studio, while the
presenter lectures from another studio. Cameras simultaneously
swap live pictures between TV screens in each location. Cameras
can be set to show the whole room, zoom in on one person or focus
on a whiteboard.
