{"name":"SP-231665","title":"TR 26.865-100 - ISAR Requirements","source":"SA WG4","contact":"Antoine Burckard","contact-id":97796,"tdoctype":"draft TR","for":"Information","abstract":"Abstract of document: An essential architectural characteristic of XR clients is the reliance on a functional split between a set of composite pre-renderers that are implemented as parts of a presentation engine and a set of post-rendering operations implemented on a lightweight end-device (AR glasses) prior to final output. The functional split assumed in split renderer architectures is a result of stringent implementation and operational requirements applicable for rendering of XR media on XR devices. For head-tracked immersive audio, the need to rely on a split renderer architecture, may depend on various factors among which the round-trip latency between the renderer in the presentation engine and the lightweight device is a decisive parameter. There are scenarios where this latency may be substantial which may prefer a split rendering approach with pose correction in the end device for binaural audio in a similar way as for video unless decoding and head-tracked binaural audio rendering on the lightweight device does not exceed its strict complexity constraints. In other scenarios, that latency may be sufficiently low, in which case the head-tracked binaural rendering can exclusively be done in the presentation engine. It is notable that the transmission over the interface may generally be bit rate constrained and dependent on the specific physical interface. Technical solutions for the provision of immersive audio in split rendering scenarios are largely dependent on the associated properties and imposed requirements, which are identified by the present technical report TR26.865 (Immersive Audio for Split Rendering Scenarios; Requirements). The present TR contains: - A detailed description of interfaces and relevant split rendering scenarios - General design guidelines for solutions for split rendering scenarios of immersive audio - Physical design constraints applicable for IVAS split rendering scenarios - Functional design constraints applicable for IVAS split rendering scenarios - Performance requirements applicable for IVAS split rendering scenarios Changes since last presentation to SA Meeting: First presentation to SA Meeting. Outstanding Issues: Detailed design constraints applicable for IVAS split rendering scenarios still to be decided. Final review and acceptance of text sections in square brackets. Clean-up including removal of editor s notes.
