CCITT standard for digital computer data interchange videoconferencing.
An ITU-T recommendation specifying protocols for data transmission in multimedia systems. http://www.itu.int/rec/recommendation.asp?type=folders&lang=e&parent=T-REC-T.120
A standard recommended by the International Telecommunications Union (ITU) in 1994 for the transmission and sharing of graphics and text over packet networks for use in teleconferencing. The standard was widely accepted in the middle and late 1990s due to the support of backers such as Robert Gill of ConferTech (now Global Crossing), Neal Starkey of DataBeam (now IBM-Lotus), Brian Hinman of Polycom (who later founded TwoWire), and many others at Microsoft. T.120 is available through Microsoft’s NetMeeting product and Lotus’s SameTime. Today, though, with streaming and other Web conferencing packages widely available, T.120 is not as popular as it was in the late 1990s.
An ITU-T overview Recommendation describing: Transmission Protocols for Multimedia Data; including multilayer protocols which considerably enhance multimedia, MCU and codec control capabilities, permitting greater MCU operational sophistication beyond that described in H.231 and H.243.
Videoconferencing systems, particularly IP-based systems, increasingly support integrated data and application sharing. T.120 is the standard for multi-site data conferencing to ensure that any two data-conferencing systems can communicate with each other. It includes standards for whiteboards (i.e. shared graphical images), file transfer and application sharing.
The standard that defines data sharing within a conference.
Multilayer protocols for graphics/data transmission.
A set of protocols for transport-independent, multi-point data conferencing that is an ITU standard.
"User Data Transmission Using a Multi-Layer Protocol (MLP)" is a comprehensive ITU-T recommendation for data conferencing.
A standard for audio and graphics exchange, supporting higher resolutions and pointing and annotation (which the H.320 standard does not).
An ITU-T standard for data transmission that enables data, application sharing, etc. to occur within the pass band of the normal videoconferencing channel.
The standard which provides support for real-time, multi-point data communication.
The ITU-T's "Transmission Protocols for Multimedia Data", a data sharing/data conferencing specification that lets users share documents during any H.32x videoconference. Like H.32x specifications, T.120 is an umbrella Recommendation that includes a number of other Recommendations. Data-only T.120 session can be held when no video communications are required, and the standard also allows multipoint meetings that include participants using different transmission media. The mandatory components of T.120 include recommendations for multipoint file transfer and shared-whiteboard implementation.
The overall standard for audiographic conferencing and multimedia data transmission
T.120 is an ITU-T standard (International Telecommunications Union) for document conferencing. Document conferencing allows two or more people to concurrently view and edit a document across a network. T.120 is the commonly used name to refer to a family of distinct standards. Many videoconferencing companies were developing their own implementations of this until Microsoft released its free NetMeeting software. Now, many companies are using NetMeeting, while perhaps enhancing it in some way.
Standard for data conferencing and conference control for interactive multimedia communication - multipoint & point-to-point.
Data protocols for multimedia conferencing.
A standard for realtime data conferencing (sharing data among multiple users). It defines interfaces for whiteboards, application viewing and application sharing. There are numerous breakdowns within the T.120 standard which handle specific functions such as multipoint service; audiovisual protocol; generic conference control; conference management (establish, terminate, etc.); network mappings; and reservation services.
An ITU-T standard addressing Real Time Data Conferencing (Audiographics). See also ITU-T.
T.120 is an ITU-T recommendation that describes a series of communication and application protocols and services that provide support for real-time, multipoint data communications. It is used by products such as Microsoft Net Meeting and Lotus Sametime to support application sharing, real-time text conferencing and other functions.
