1 Scope p. 6
The present document focuses on IMS-based conversational AR (Augmented reality) services. AR services can overlay media (e.g., video, audio, text, etc.) on top of the user's real perception. Conversational AR services as described by the present document typically include a bidirectional conversational A/V connection in addition to other non-real-time AR media for collaboration or communication between two or more users.

3.1 Terms p. 6
For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
AR data:
Collection of information to be exchanged among participants in a call with AR experience. It includes AR media and AR metadata.
AR media:
Media (e.g., audio, video, text or image) that will be rendered by the AR-MTSI client as an overlay over the user's real perception. This includes traditional 2D media (e.g., a 2D audio stream rendered to be perceived by the user to originate from their left side) and 3D media (e.g., spatial audio and volumetric video).
AR metadata:
Data that provides information on AR media and its rendering. This includes pose, spatial descriptions and scene descriptions.
AR-MTSI client:
A DCMTSI client supporting AR capabilities as defined by this specification.
AR MRF:
An AR-MTSI client implemented by functionality included in the MRFC and the MRFP.
AR MF:
An AR-MTSI client implemented by functionality included in the MF.
AR-MTSI client in terminal:
An AR-MTSI client that is implemented in a terminal or UE. The term "AR-MTSI client in terminal" is used in this document when entities such as AR MF/MRF is excluded.
Split rendering:
The procedure in which a UE offloads some of the media processing related to rendering tasks to a media function as considered for network centric AR IMS session procedures in TS 23.228.
