While users always struggle to get hands on with videoconferencing, there are some standards and terminology that make things easier. Along with videoconferencing come an ever-increasing number of standards, terminologies and buzz-words. This can make it difficult to understand a technology that is available as well as compatible. Here are some things bound to leave the end user confused - H.300, G.700, T.120 and H.460; ISDN, LAN, WAN, ADSL, VPN and POTS; NTSC, PAL and CIF. Added to the terminology is the use of the forthcoming media-enabled 3G mobile phone that users will have to get accustomed to. They will also have to understand how to link this phone with existing systems. This paper explains all of these complicated standards, terminologies and buzz-words. It also helps to understand how the standards and terminology relate to the various communications infrastructures of video conferencing along with the relation between all of these. While it is easy to gather general knowledge on the working of videoconferencing systems, the paper also recommends a number of technical papers that can be helpful. The paper also discusses telecommunications standards that are set by the United Nations agency International Telecommunications Union (ITU) and the Internet Engineering Task Force (IETF). Products that follow these standards will allow users to participate in a conference regardless of their platform. These standards apply to desktop video conferencing across the globe and therefore make systems across geographies easily compatible.
