In order to address this, generic modelling considerations are introduced and for different services reference designs, simulation models and suitable quality metrics are reported. This information permits to obtain accurate information on exact bitrate and delay requirements in uplink and downlink, develop detailed traffic traces, develop suitable statistical models for media and XR traffic and to evaluate the expected media quality of such services. The information may be used by other 3GPP groups in order to assess media quality for different configuration of 5G System parameters, as well as for evaluating the requirements in terms of QoS for XR and media services.

{"name":"SP-230980","title":"TS 26.258-100 - Codec for Immersive Voice and Audio Services - C code (floating point)","source":"SA WG4","contact":"Andrijana Brekalo","contact-id":91743,"tdoctype":"draft TS","for":"Approval","abstract":"Abstract of document: The codec for Immersive Voice and Audio Services (IVAS) is part of a framework comprising besides encoder and decoder, renderer associated with the support of stereo and immersive audio formats. The IVAS codec is an extension of the 3GPP Enhanced Voice Services (EVS) codec; it provides full and bit exact EVS codec functionality for mono speech\/audio signal input. On top of that the IVAS codec is optimized for encoding and decoding of stereo and immersive audio formats, Immersive audio formats comprise multi-channel audio (5.1, 5.1.2, 5.1.4, 7.1, 7.1.4 setups), scene-based audio (Ambisonics up to order 3), metadata-assisted spatial audio (MASA), and object-based audio (Independent Stream with Metadata (ISM) up to 4 ISMs). In addition, the following combined immersive audio formats are supported: object-based audio with scene-based audio (OSBA, up to 4 ISMs with Ambisonics) and object-based audio with metadata-assisted spatial audio (OMASA, up to 4 ISMs with MASA). Rendering between many of the formats is supported, including binaural rendering for headphone reproduction with head-tracking and rendering to various loudspeaker configurations. The present technical specification TS26.258 (Codec for Immersive Voice and Audio Services; C code (floating-point)) contains: - Specification of C code structure - Specification of file formats as used by the IVAS codec, incl. normative Annex A (Metadata-assisted spatial audio (MASA) format) and normative Annex B (Binary renderer config metadata format) - Floating-point C code of the IVAS codec as electronic attachment, in IVAS Software Version 1.0. Changes since last presentation to SA Meeting: First presentation to SA Meeting. Outstanding Issues: None. Contentious Issues: None.","secretary_remarks":"This DRAFT TS was approved","agenda_item_sort_order":86,"ainumber":"6.8.4","ainame":"SA WG4 Specifications for Approval \/ for Information and Approval","tdoc_agenda_sort_order":11520,"status":"approved","reservation_date":"2023-09-03 21:57:31","uploaded":"2023-09-06 15:11:05","revisionof":"","revisedto":"","release":"Rel-18","crspec":26.258,"crspecversion":"1.0.0","workitem":[{"winame":"IVAS_Codec"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_SA\/TSG_SA\/TSGs_101_Bangalore_2023-09\/Docs\/SP-230980.zip","group":"SP","meeting":"SP-101","year":2023,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
