The present document specifies a client for the IMS-based telepresence service supporting conversational speech, video and text transported over RTP. Telepresence is defined as a conference with interactive audio-visual communications experience between remote locations, where the users enjoy a strong sense of realism and presence between all participants (i.e. as if they are in same location) by optimizing a variety of attributes such as audio and video quality, eye contact, body language, spatial audio, coordinated environments and natural image size. A telepresence system is defined as a set of functions, devices and network elements which are able to capture, deliver, manage and render multiple high quality interactive audio and video signals in a telepresence conference. An appropriate number of devices (e.g. cameras, screens, loudspeakers, microphones, codecs) and environmental characteristics are used to establish telepresence.
The media handling capabilities of a telepresence client (TP UE) are specified in the present document. A TP UE supports Multimedia Telephony Service for IMS (MTSI) UE media handling capabilities [TS 26.114], but it also supports more advanced media handling capabilities. The media handling aspects of a TP UE within the scope of the present document include media codecs, media configuration and session control, data transport, audio/video parameters, and interworking with MTSI.
