[{"name":"SP-231299","title":"TS 26.254-100 - Codec for Immersive Voice and Audio Services; Rendering","source":"SA WG4","contact":"Antoine Burckard","contact-id":97796,"tdoctype":"draft TS","for":"Information","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 TS26.254 (Codec for Immersive Voice and Audio Services; Rendering) contains: - A comprehensive description of the rendering functions of the decoder\/renderer for Immersive Voice and Audio Services (IVAS codec). - References to other specifications for elsewhere defined subcomponents, especially TS 26.253 (Codec for Immersive Voice and Audio Services; Algorithmic Description), and TS 26.258 (Codec for Immersive Voice and Audio Services (IVAS); C code (floating point)). Changes since last presentation to SA Meeting: First presentation to SA Meeting. Outstanding Issues: Completion of description of rendering features, in alignment with TS 26.253. Contentious Issues: None.","secretary_remarks":"Noted","agenda_item_sort_order":77,"ainumber":"6.7.4","ainame":"SA WG4 Specifications for Information","tdoc_agenda_sort_order":11810,"status":"noted","reservation_date":"2023-11-27 11:00:22","uploaded":"2023-12-06 11:05:56","revisionof":"","revisedto":"","release":"Rel-18","crspec":26.254,"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_102_Edinburgh_2023-12\/Docs\/SP-231299.zip","group":"SP","meeting":"SP-102","year":2023,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
