Video Conferencing System

Video Conferencing System

A videoconference or video conference (also known as a videoteleconference) is a set of interactive telecommunication technologies which allow two or more locations to interact via two-way video and audio transmissions simultaneously. It has also been called ‘visual collaboration’ and is a type of groupware.

 

Videoconferencing differs from videophone calls in that it’s designed to serve a conference rather than individuals. It is an intermediate form of videotelephony.

 

Videoconferencing uses telecommunications of audio and video to bring people at different sites together for a meeting. This can be as simple as a conversation between two people in private offices (point-to-point) or involve several sites (multi-point) with more than one person in large rooms at different sites. Besides the audio and visual transmission of meeting activities, videoconferencing can be used to share documents, computer-displayed information, and whiteboards.

 

components required for a videoconferencing system include:

  • Video input : video camera or webcam
  • Video output: computer monitor , television or projector
  • Audio input: microphones, CD/DVD player, cassette player, or any other source of audio outlet.
  • Audio output: usually loudspeakers associated with the display device or telephone
  • Data transfer: analog or digital telephone network, LAN or Internet

 

Videoconferencing can enable individuals in distant locations to participate in meetings on short notice, with time and money savings. Technology such as VoIP can be used in conjunction with desktop videoconferencing to enable low-cost face-to-face business meetings without leaving the desk, especially for businesses with widespread offices. The technology is also used for telecommuting, in which employees work from home.
