Videoconferencing systems come in many degrees of sophistication and cost.
Video and audio signals are digitized with a Codec, in hardware and/or software.
The signals are compressed and sent out over a network, primarily IP or ISDN.
Most systems adhere to common standards for video conferencing in order to be compatible with other brands of devices.
The most popular standards are h.323 and SIP, along with video compression standards h.264 for video and g.711 for audio. You can check out tech details at ITU: Committed to connecting the world
It is one of the more complex applications and can really test the resiliency of a network.
