onducting a conference between two or more participants at different sites by using computer  networks to transmit audio and video data. For example, a point-to-point (two-person) video conferencing system works much like a video telephone. Each participant has a video camera, microphone, and speakers mounted on his or her computer. As the two participants speak to one another, their voices are carried over the network and delivered to the other's speakers, and whatever images appear in front of the video camera appear in a window on the other participant's monitor.

In video conferencing, synchronized images and verbal communication are transmitted between two or more locations. When holding a video conferencing event, a codec translates the analog information received by the microphones and video cameras into digital information, which is then transmitted to another codec that translates the digital information back to the original sounds and images, which the video conferencing participants can understand.
