[{"name":"SP-240034","title":"TS 26.256-200 - Codec for Immersive Voice and Audio Services - Jitter Buffer Management","source":"SA WG4","contact":"Antoine Burckard","contact-id":97796,"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 TS26.256 (Codec for Immersive Voice and Audio Services; Jitter Buffer Management) contains: - General overview of the Jitter Buffer Management of the IVAS Codec and specification of the subcomponents - References to other specifications for elsewhere defined subcomponents, especially TS26.448 (Codec for Enhanced Voice Services; Jitter Buffer Management) and TS26.253 (Codec for Immersive Voice and Audio Services; Algorithmic Description). Changes since last presentation to SA Meeting: Updates towards specification approval at the SA Meeting. Outstanding Issues: None. Contentious Issues: None.","secretary_remarks":"This was block approved.","agenda_item_sort_order":88,"ainumber":"6.10.4","ainame":"SA WG4 Specifications for Approval \/ for Information and Approval","tdoc_agenda_sort_order":12080,"status":"approved","reservation_date":"2024-02-27 13:34:10","uploaded":"2024-03-01 17:29:37","revisionof":"","revisedto":"","release":"Rel-18","crspec":26.256,"crspecversion":"2.0.0","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_103_Maastricht_2024-03\/Docs\/SP-240034.zip","group":"SP","meeting":"SP-103","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
