How Does the Data Transfer Work? Once digitally compressed, the video and audio data can be transmitted over a digital network. Data is sent to the other participant's video conferencing system and then decompressed and translated back into analog video images and audio sounds.

Generally, each configures the data into packets, with each packet having a 'header' that identifies its contents. The protocol used is usually determined by the need to have reliable or unreliable communications.
