The theory's the same, the transmission has changed In the earlier days of video conferencing, T1, ATM and ISDN lines were used almost exclusively but were really only practical for room-based video conferencing systems. Point to point video conferencing Point to point video conferencing is just what it sounds like - a link between two different points on the planet, or two different video conferencing terminals. Some common types of video transmission for video conferencing include:

Continuous Presence video conferencing, which allows up to four conference sites to be seen simultaneously on split screens. This is usually used if you have a small group or individuals in separate locations and will primarily be seeing close-up shots.
Universal Control video conferencing is controlled by the initiating conference site. The primary site determines who sees what at all other sites.
Voice Activated video conferencing is by far the most common type used today. The image with these videoconferencing systems (http://avtakeout.com) shifts to the site that is currently activating the microphone so that you can always see whoever is speaking. However, if there is a good deal of background noise participants should mute their microphones when they aren't talking in order to avoid the image jumping about needlessly.
Web conferencing solutions such as Click to Meet, Lotus's SameTime, and WebEx also offer corporate solutions that are based on Internet video conferencing. Recent innovations have largely circumvented these problems by designing firewall solutions that recognize video conferencing signaling requests and allow the information packets to bypass the firewall or router without disabling the firewall protection for other traffic. How video conferencing works will certainly evolve over time and improve in the coming years, but a basic understanding of what it is and how it works now will help you make the best choice for you when you're ready to begin using video conferencing yourself.
