Video Conferencing is a multi-way, simultaneous video and audio communication using telecommunications technology. Video conferencing allows individuals from across the globe to communicate effortlessly.
A number of key components are required to successfully hold or participate in a video conference. These include:
Video Input – Video Conferencing requires a video input and is usually done through a webcam or, a video camera such as a Polycom Trio 8800.
Audio Input – For video to accompany sound, there needs to be an audio input as well. It is most commonly achieved through a microphone, although DVD/CD players are a source of audio too.
Video Output – For the video to be interpreted, a platform is needed to output the video on. This can be done using a number of items but most commonly a computer monitor, television or projector is used.
Audio Output – It is similar to the video output but for sound. Audio output usually runs through loudspeakers.
Data Transfer – Commonly the video/audio data is transferred across a telephone network, be it analog or digital; the internet or LAN in case of local conference.
Computer – A computer is required to tie the other components of the conference together. The computer helps compress and decompress the data using a codec and also maintains the data linkage over the network.
These components when put together form a video conferencing system. Dedicated and desktop are the 2 types of system. A dedicated video conferencing system is a device with all the required components built-in and is purpose built. A desktop system is an add-on to a regular computer desktop turning it into a video conferencing system.
