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.
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 Template Common structure for T.120 applications. T.122 - Multipoint Communication Service Service definition for T.123 networks (implemented in T.125). T.123 - Audiovisual Protocol Stacks Protocol stacks for terminals and MCUs. T.124 - Generic Conference Control Conference management (establish, terminate, etc.). T.125 - Multipoint Communication Service Protocol implementation of T.122. T.126 - Still Image & Annotation Protocol Whiteboards, graphic display and image exchange. T.127 - Multipoint Binary Transfer Protocol for exchanging binary files. T.128 - Audio Visual Control Interactive controls (routing, identification, remote control, source selection, etc.) T.130 - Real-Time Architecture Interaction between T.120 and H.320. T.131 - Network Specific Mappings Transport of real-time data used with T.120 over LANs. T.132 - Real-Time Link Management Creation and routing of real-time data streams. T.133 - Audio Visual Control Services Controls for real-time data streams. T.RES - Reservation Services Interaction between devices and reservation systems. T.Share - Application Sharing Protocol Remote control protocol. T.TUD - User Reservation Transporting user-defined data.
