Video Out

It is common in video conferencing to think most about the inputs, and neglect consideration of how of output the signals sent out by the conferencing partner.

The three main types of output display are:

Computer Monitor
Computer Monitor
  • The Computer Monitor is the usual choice for conferences witha small number of participants.
  • The incoming video signal is shown either in a small window, or perhaps full screen.
  • Picture quality tends to be good though screen sizes are commonly quite small restricting how many people can share a display.
  • Normally a Computer Monitor can only be used in conjunction with a PC.
Projector
projector
  • A Projector can be used to show video pictures at large sizes.
  • This can share an image with a whole class or even assembly hall.
  • Often the image quality being recieved looks poor when blown up to a large size. An image that is appropriate for use on a monitor might look blurred and low quality on a cinema-sized screen.
Video Monitor/Televisions
Telivision Monitor
  • Video monitors look like traditional televisions but lack tuner features.
  • Both Video Monitors and Televisions are designed to take traditional video signals from VC equipment.
  • The resulting outputs tend to be of good quality.
  • Such units are self-contained and will offer audio and video output in the same unit, and are more portable than either a PC/Computer Monitor or Projector/Screen combination.

Some systems support the use of multiple output displays. For example a two monitor set-up might display both the transmitted signal and the recieved signals simultaneously.
