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 TS26.250 (Codec for Immersive Voice and Audio Services; General overview) contains: - General overview including overview figures of audio processing functions on transmit and receiving sides - Introductions and references to major components of IVAS set of specifications such as Transcoding functions, Rendering, C-code, Test sequences, Discontinuous Transmission, Error concealment of lost frames, etc. Changes since last presentation to SA Meeting: First presentation to SA Meeting.

{"name":"SP-230982","title":"TR 26.941-100 - Network Slicing Extensions for 5G media services","source":"SA WG4","contact":"Andrijana Brekalo","contact-id":91743,"tdoctype":"draft TR","for":"Information","abstract":"Abstract of document: This technical report covers key issues, candidate solutions, and potential requirements for supporting network slicing with 5GMS architecture. The technical report reviews network slicing standardization, and describes different slice management processes that are relevant for specifying media streaming aspects of network slicing. The technical report also documents relevant scenarios and use cases related to media streaming that can be addressed using network slicing. The report specifies collaboration options for downlink media streaming based on network slicing usage scenarios by the MNOs. Further, the technical report identifies key issues related to service provisioning, migration of media flows to alternate network slices (because of slice service continuity issues) and bootstrapping application invocation on network slice. Candidate solutions to some of the above key issues are outlined. Changes since last presentation to SA#100-e: This is the first presentation to SA. Outstanding Issues: The remaining work includes the following items: 1. Impact of network slice replacement procedure on 5G Media Streaming. 2. Proposed updates to 5GMS procedures and data model definitions to support network slicing. 3. Summary of candidate solutions for each Key Issue, including assessment of feasibility. 4. Overall conclusion and recommendations for normative work. Contentious Issues: None foreseen.","secretary_remarks":"Noted","agenda_item_sort_order":79,"ainumber":"6.7.4","ainame":"SA WG4 Specifications for Information","tdoc_agenda_sort_order":11390,"status":"noted","reservation_date":"2023-09-03 22:13:36","uploaded":"2023-09-06 15:11:05","revisionof":"","revisedto":"","release":"Rel-18","crspec":26.941,"crspecversion":"1.0.0","workitem":[{"winame":"FS_MS_NS_Ph2"}],"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-230982.zip","group":"SP","meeting":"SP-101","year":2023,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0}]
