The present document provides an overview of delivery of 3D graphics of games that are running on a high-performance server to client devices that would otherwise not have the resources to run these games natively. The present document describes the use cases, high level requirements and different solution approaches, and identifies the main area(s) where standardization work would be needed. Exploring the nature and content of what is going to be exchanged between servers and clients constitutes the main topic of the present document The primary aim for this technology is to enable casual gaming scenarios, and it is not the primary aim to try to satisfy hardcore gamers, since we have to be realistic about what can be achieved with the current state of networking and server technology. Because of the nature of the content and in order to focus on feasible solutions, we may exclude certain type of network connections to be used, such as using "unreliable" or high-latency wireless connections such as 802.11b/g. We expect to have a broadband connection between the client and the server, without too many intermediate hops. In the present document we do not address deployment issues, such as integration into a Content on demand infrastructure (e.g. user registration, pricing, purchasing), or integration into a QoS framework (e.g. prioritization of gaming streams compared to other types of streams). Also, use cases and synchronization issues related to multi-player gaming, whereby different connection speeds/types could result in different response times, are out of scope of the present document.

This Group Specification provides additions and corrections to the GS-009 NGSI-LD API specification, based on feedback received from developers in the linked-data, internet-of-things, mobile-apps and smart-applications communities, as well as from end users and stakeholders.

The purpose of this Group Report is to explain with examples the usage of NGSI-LD information model and API, as defined in GS-004 prelimAPI, and considering also some use cases from GR-002 for ICT professionals. Worked examples are provided, with code fragments made available in a public repository. No changes in the GS-004 prelimAPI specification can be introduced or proposed in this document.

Defining indicators (KPIs) for Smart Cities expressing city level in terms of People, Planet, Prosperity and Governance.,

This extension has been created by investigating resources from potential stakeholders of the ontology, such as standardization bodies (e.g. Open Geospatial Consortium), associations (e.g. Spanish Federation of Municipalities and Provinces), IoT platforms (e.g. FIWARE) and European projects and initiatives (e.g. ISA2 programme, as reported in ETSI TR 103 506)

The report will identify the role of existing standards relevant to augmented reality and document any interoperability gaps. This activity will analyse the standardization work done around augmented reality in various standards setting organizations.

The present document collects information on eXtended Reality (XR) in the context of 5G radio and network services. The primary scope of the present document is the documentation of the following aspects:- introducing Extended Reality by providing definitions, core technology enablers, a summary of devices and form factors, as well as ongoing related work in 3GPP and elsewhere,- collecting and documenting core use cases in the context of Extended Reality,- identifying relevant client and network architectures, APIs and media processing functions that support XR use cases,- analysing and identifying the media formats (including audio and video), metadata, accessibility features, interfaces and delivery procedures between client and network required to offer such an experience,- collecting key performance indicators and Quality-of-Experience metrics for relevant XR services and the applied technology components, and- drawing conclusions on the potential needs for standardisation in 3GPP.

The present document provides reference test material and test results for improved usability of technologies in 3GPP TS 26.118: Virtual Reality (VR) profiles for streaming applications. The specification 3GPP TS 26.118 includes several VR media profiles for video and a single media profile for audio with different configuration options. The specification focuses primarily on interoperability requirements for VR360 applications, but does not address performance characterization of the solutions. In order for content providers and the rest of the ecosystem to be able to select and configure the technologies defined in 3GPP TS 26.118 and to generate content for streaming applications, collecting such information would be most valuable.

The present document specifies a functional reference architecture for AR components, systems and services. The structure of this architecture and the functionalities of its components have been derived from a collection of use cases, ETSI GR ARF 002 (V1.1.1): Augmented Reality Framework (ARF) Industrial use cases for AR applications and services, and an overview of the current landscape of AR standards, ETSI GR ARF 001 (V1.1.1): Augmented Reality Framework (ARF); AR standards landscape. The present document introduces the characteristics of an AR system and describes the functional building blocks of the AR reference architecture and their mutual relationships. The generic nature of the architecture is validated by mapping the workflow of several use cases to the components of this framework architecture.

The present document reviews the high level Reference Point requirements between the Scene Management and External Application Support functions as they are described in ETSI GS ARF 003 (V1.1.1): Augmented Reality Framework (ARF) AR framework architecture.

The present document provides an overview and an introduction to the interface specification for the reference points "AR 16 - World Anchors" and "AR 17 - Reference Objects" of the AR framework architecture, ETSI GS ARF 003 (V1.1.1): Augmented Reality Framework (ARF) AR framework architecture, developed by the ETSI Industry Specification Group (ISG) for an Augmented Reality Framework (ARF). The actual interface specification is provided as OpenAPI™ specification, ARF005 - World Storage API, revision 1.0.0, and forms the baseline for the present document.

The present document collects information on glass-type AR/MR devices in the context of 5G radio and network services. The primary scope of this Technical Report is the documentation of the following aspects:- providing formal definitions for the functional structures of AR glasses, including their capabilities and constraints,- documenting core use cases for AR services over 5G and defining relevant processing functions and reference architectures,- identifying media exchange formats and profiles relevant to the core use cases,- identifying necessary content delivery transport protocols and capability exchange mechanisms, as well as suitable 5G system functionalities (including device, edge, and network) and required QoS (including radio access and core network technologies),- identifying key performance indicators and quality of experience factors,- identifying relevant radio and system parameters (required bitrates, latencies, loss rates, range, etc.) to support the identified AR use cases and the required QoE, and- providing a detailed overall power analysis for media AR related processing and communication.
