What is H.320 video conferencing?
H.320 is the name of the standard for video conferencing using what are called “switched services” like ISDN and Switched-56. The standard was established in 1990. There are a number of protocols related to the H.320 standard. This series of standards govern basic video communications including graphical communications and audio over commonly used time division multiplexed (TDM) circuits. b) This H.320 type of video conferencing has historically been the most popular and flexible. The standard governs communications over digital channels, similar to those your telephone uses deep within the telecommunications network. Frequently, in order to ensure a high degree of picture and sound quality, a technique called “inverse multiplexing” is used to aggregate channels for higher bandwidth. c) H.320 video communications systems are often used on networks where usage charges apply such as on networks that use ISDN services from local and long distance telephone companies.
