[{"name":"SP-220242","title":"New WID on Media Capabilities for Augmented Reality (MeCAR)","source":"SA WG4","contact":"Jayeeta Saha","contact-id":85340.0,"tdoctype":"WID new","for":"Approval","abstract":"Objective: This work item defines service-independent media capabilities for AR devices. In particular, the following objectives are considered: - Define at least one AR device category that addresses the constraints of an EDGAR-type AR glass o Note: Additional device categories may be defined, but with lower priority. - For each AR device category o Define a reference terminal architecture regarding media capability aspects for this AR device category o Define media types and formats produced and consumed by the AR device, including basic scene descriptions, audio, graphics and video as well as sensor information and metadata about user and environment. o Define the integration of the relevant existing 3GPP codecs into the reference terminal architecture o Define decoding capabilities, including support for multiple parallel decoders o Define encoding capabilities o Define security aspects related to the media capabilities o Define the required, recommended and optional media capabilities for this AR device category - Integrate IVAS into suitable AR device categories, once IVAS is available - Define capability exchange mechanisms based on complexity of AR media and capability of device to support EAS KPIs for provisioning of edge\/cloud resources o Note: Identify a suitable existing capability framework, or if it does not exist, we need to work with the broader industry (e.g., IETF, KHRONOS, W3C, etc.) to get this done. - Identify which QoE metrics from VR QoE metrics can be reused or enhanced for AR media (e.g., resolution per eye, Field of view (FOV), round-trip interaction delay, etc.) and define relevant KPIs that are dedicated to AR\/MR - Specify additional relevant KPIs and simple QoE Metrics for AR media - Specify encapsulations into RTP, ISOBMFF and CMAF - Specify the relevant codec-level parameters for session setup and negotiation of the media delivery and provide instantiations for SDP and DASH MPD - Enable AR media in 5G Media Streaming by defining suitable 5GMS profiles based on AR media capabilities - Define typical traffic characteristics for AR media","secretary_remarks":"CC#3: Block Approved","agenda_item_sort_order":39,"ainumber":"6.5","ainame":"New Release 18 Work Item Descriptions","tdoc_agenda_sort_order":11380,"status":"approved","reservation_date":"2022-03-04 19:46:11","uploaded":"2022-03-09 19:31:12","revisionof":"","revisedto":"","release":"Rel-18","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_95E_Electronic_2022_03\/Docs\/SP-220242.zip","group":"SP","meeting":"SP-95-e","year":2022,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
