Name The software required to run video conferencing
The software and hardware required to run video conferencing is very sophisticated. Apart from obvious items (that is large screen, devices and computer like mouse, etc.) following briefly describes what is required to have a video conference:
- Delegates speak into a central microphone
- Webcam takes a video image
- Delegates hear speech by loud speaker system at each venue
- System uses internet/WAN/modem to transmit data
- requires use of compression software for audio/video signals
- Systems may use CODEC (that converts and compresses analogue data in digital data for sending down digital lines)
- Requirement for echo cancellation software (this enables talking in real time and keeps communications synchronised)
- Audio and video images are heard/seen in real time through loud speakers/on large monitors.
