T-120 meaning

An ITU standard for real-time data conferencing (sharing data among multiple users). It defines interfaces for whiteboards, application viewing and application sharing. The ITU standards for videoconferencing are H.320 and H.323. Following are all the elements of T.120. See H.239 and videoconferencing standards.T.121 - Generic Application TemplateCommon structure for T.120 applications.T.122 - Multipoint Communication ServiceService definition for T.123 networks (implemented in T.125).T.123 - Audiovisual Protocol StacksProtocol stacks for terminals and MCUs.T.124 - Generic Conference ControlConference management (establish, terminate, etc.).T.125 - Multipoint Communication ServiceProtocol implementation of T.122.T.126 - Still Image & Annotation ProtocolWhiteboards, graphic display and image exchange.T.127 - Multipoint Binary TransferProtocol for exchanging binary files.T.128 - Audio Visual ControlInteractive controls (routing, identification, remote control, source selection, etc.)T.130 - Real-Time ArchitectureInteraction between T.120 and H.320.T.131 - Network Specific MappingsTransport of real-time data used with T.120 over LANs.T.132 - Real-Time Link ManagementCreation and routing of real-time data streams.T.133 - Audio Visual Control ServicesControls for real-time data streams.T.RES - Reservation ServicesInteraction between devices and reservation systems.T.Share - Application Sharing ProtocolRemote control protocol.T.TUD - User ReservationTransporting user-defined data.

The ITU-T Recommendation for the multipoint transport of multimedia data, which can include whiteboarding or binary files. The T.120 series of recommendations supports a broad range of underlying network technologies, and can work either independently or under the H.320 umbrella.T.120 is entirely platform-independent, and can run in a variety of network environments, involving either reliable or unreliable data transport. T.120 supports both unicast and multicast modes of operation. See also binary, data, H.320, multicast, multipoint, platform independent, transport, unicast, and whiteboarding.
