Identify and document beyond 2D formats, that are market-relevant within the next years, generated from established and emerging capturing systems (including cameras for spatial video capturing), contribution, and usable on display technologies (smartphones, VR HMDs, AR glasses, autostereoscopic and multiscopic displays). NOTE 1: The work is expected to build upon and extend the findings documented in TR 26.928, TR 26.998 and TS 26.119. 2. Establish and document a set of beyond 2D video end-to-end reference scenarios, including real-time communication, streaming services, split rendering, and messaging and corresponding workflows (capturing, encoding, packaging, delivery, decoding, rendering, including general constraints on latency, as well as complexity) to support 3GPP network related delivery and devices leveraging the generation or display technologies. This includes identifying and defining relevant beyond 2D formats in the context of above workflows, and representation technologies to support delivery of these formats within 3GPP networks. NOTE 2: Alignment with the generalized media delivery architecture defined in TS 26.501\/506 is expected, primarily addressing reference points M2 and M4. 3. Prioritize the scenarios and the associated formats based on market relevance for further evaluation. NOTE 3: The scenario priority will be determined as the first step following the agreement on the specification skeleton and scope. 4. Define concrete evaluation framework per scenario (test conditions, KPIs, Metrics, test sequences, agreed reference signals) based on the above prioritized reference scenarios, and evaluate the feasibility and performance of existing 3GPP codecs as well as potentially new codecs to support the scenarios. NOTE 4: Reuse existing performance results from MPEG or other standard organizations, fitting in the evaluation framework defined in 3GPP may be considered and is recommended to be done. If there are no suitable existing performance results, communication with MPEG to ask for potential further evaluation on selected topics may be done, but 3GPP may also initiate the evaluation independently of MPEG. 5.

The main objectives of this study include: Refine relevant SA WG1 use cases (5.5, 5.8, 5.9, 5.10 and 5.14) in TR 22.882 in the SA WG4 context. Document existing APIs, metrics and mechanisms inside or outside 3GPP that could be used for energy measurement, reporting and exposure of media services. This includes whether and what information is exposed, how it is exposed, and at what granularity (QoE measurement and reporting, QoS measurement and reporting, audience measurement and reporting, event exposure, CMCD reporting, etc.). Study the feasibility of having implementation-independent metrics and a framework to evaluate the energy usage\/savings of multimedia standards features and proposals. NOTE 1: The study will consider the work done by SA WG2 and WG5 regarding energy consumption measurement, information collection and energy saving, and reuse it as much as possible. NOTE 2: Exchanges with other 3GPP WGs, CTA WAVE and DVB may be needed, e.g. via formal Liaison Statements.","secretary_remarks":"Revision of SP-240062.

Specifically, the following objectives are identified: 1. Document the following additional Key Issues in more detail, in particular how they relate to the 3GPP Media Delivery architecture and\/or the MBS User Service architecture: a) Common Client Metadata. b) Common Server-and Network-Assisted Streaming. c) Multi-CDN and Multi-Access Media Delivery. d) Modem Usage Optimized Media Streaming. e) DRM and Conditional Access. f) In-session Unicast Repair for MBS Object Distribution. g) MBS User Service and Delivery Protocols for eMBMS. h) Selected MBMS Functionalities not supported in MBS. i) DASH\/HLS Interoperability. j) Further harmonization of RTC and Streaming for Advanced Medial Delivery. k) Issues identified by Market Representation Partners. l) Improved QoS support. m) Impacts and opportunities of QUIC for segmented content delivery 2. Study collaboration scenarios between the Application Service Provider and the 5G System and for each of the key topics. 3. Based on existing architectures, develop one or more deployment architectures that address the key topics and the collaboration models. 4. Map the key topics to basic functions and develop high-level call flows. 5. Identify the issues that need to be solved. 6.
