The International-Telecommunications-Union (ITU) (formerly: Consultative Committee on International-Telegraphy-and-Telephony (CCITT)) has three umbrellas of standards for video conferencing definition.

H.320 is known as the standard for PSTN or videoconferencing over ISDN (it is accessible to anyone with a high-speed Internet connection, such as DSL). See also H323.  video_conferencing_definition.pdf

H.264 SVC (Scalable Video Coding) is data compression techniques that enables video conferencing systems to achieve highly error resilient IP video transmission without quality of service enhanced lines. This has enabled wide scale deployment of high definition desktop video conferencing and made possible new architectures which reduce latency between transmitting source and receiver, resulting in fluid communication (less pauses).

In addition, an attractive factor for VoIP video conferencing definition is that it is easier to set-up for utilisation with a live video conferencing call along with web-conferencing for use in applications and collaboration. These combined technologies enable users to have a much richer multimedia environment for instant meetings, collaborations and presentations.

The Unified Communications Interoperability Forum:. The organization’s vision is to maximize the interoperability of UC. Founding members of UCIF include HP, Microsoft, Polycom, Logitech/LifeSizeCommunications and Juniper Networks.
