Standard

This document provides context, motivation, and use case descriptions for a set of MPEG standards that collectively deliver media directly to render-based applications such as game engines with a renderer component, or standalone renderers. Emerging examples where such applications are especially relevant include “metaverse” applications and immersive displays where such displays provide an interface to components (e.g., renderers) of existing game engines; e.g., Unreal Engine by Epic Games, Inc. and Unity by Unity Technologies. This document:(1) describes the motivators leading to the development of new MPEG standards that facilitate the streaming of media to render-based applications;(2) provides an overview of a media workflow from content production to content distribution;(3) provides general information on relevant components of render-based systems including game engines, and renderers;(4) differentiates between visual media distributed for video-based applications and visual media distributed to render-based applications;(5) identifies key components and resources (compute, storage, or network) comprising a heterogeneous set of immersive displays and other render-based applications; and(6) documents use cases for end-to-end interoperability, including Audio, Video, Graphics and Systems aspects for render-based systems and applications.

This document specifies the conformance and reference software implementing ISO/IEC 23093-3. The information provided is applicable for determining the reference software modules available for ISO/IEC 23093-3, understanding the functionality of the available reference software modules, and utilizing the available reference software modules. Furthermore, this document provides means for conformance testing, i.e. bitstreams - XML descriptions that conform or do not conform to ISO/IEC 23093-3.

ISO/IEC 18023-1:2005 addresses the concepts, syntax and semantics for the representation and interchange of environmental data. It specifies: - a data representation model for expressing environmental data; - specifications of the data types and classes that together constitute the data representation model; and- an application program interface that supports the storage and retrieval of environmental data using the data representation model.ISO/IEC 18023-1:2005 also specifies topological, rule-based, and other constraints that ensure appropriate data can be available for applications that rely on automatically generated behaviours when interacting with environmental data.

This document describes best practices for use case projects in terms of characterization, template, plan and maintenance. It is intended to developers of use case projects, including in the context of standardisation. The document can be used to complement existing methodology standards such as IEC 62559 or IEC Guide 125.

This document provides guidance on the integration of IoT systems and digital twins in data spaces.

This document specifies an Internet of Things (IoT) reference architecture (IoT RA). The IoT RA is a generalization of existing practice including the distinguishing characteristics of IoT systems and other 195 fundamental characteristics exhibited by IoT systems. The IoT RA addresses stakeholder concerns related to 196 the business value of IoT systems. The IoT RA also addresses the interactions between the IoT system, the 197 users, and the physical environment. Implementation of IoT systems is also addressed in this IoT RA. Among 198 the characteristics specified in the IoT RA are abstract functions within IoT systems and a variety of structures 199 that are used to construct IoT systems.

This document is the first of a family of standards. ISO 19101-1:2014 defines the reference model for standardization in the field of geographic information. This reference model describes the notion of interoperability and sets forth the fundamentals by which this standardization takes place. Although structured in the context of information technology and information technology standards, ISO 19101-1:2014 is independent of any application development method or technology implementation approach.

ISO 19103:2015 provides rules and guidelines for the use of a conceptual schema language within the context of geographic information. The chosen conceptual schema language is the Unified Modeling Language (UML). ISO 19103.2015 provides a profile of the Unified Modelling Language (UML). The standardization target type of this standard is UML schemas describing geographic information.

ISO 19104:2016 specifies requirements for the collection, management and publication of terminology in the field of geographic information. The scope of this document includes: - selection of concepts, harmonization of concepts and development of concept systems, - structure and content of terminological entries, - term selection, - definition preparation, - cultural and linguistic adaptation, - layout and formatting requirements in rendered documents, and - establishment and management of terminology registers.ISO 19104:2016 is applicable to International Standards and Technical Specifications in the field of geographic information.

This standard establishes a uniform set of definitions, and a methodology to assess the socio-technical considerations and practices regarding (“XR”) Extended Reality (Augmented Reality, Virtual Reality, Immersive Web and Spatial Web technologies) where this methodology shapes the positive design of XR systems. The Standard provides the following:a) a high-level overview of the technical and socio-technical aspects of XR;b) a set of XR definitions and classifications based on existing XR research and application verticals;c) a standardized definition of ethical assessment methodologies of XR products, services and systems; andd) a high-level ethical (where "ethical" is defined as "Supporting the realization of positive values or the reduction of negative values") assessment methodology for the design of XR products, services, or systems.The applied ethical approach utilizes IEEE's Ethically Aligned Design (EAD). “Positive” is defined as the support of improved human flourishing” (or “human wellbeing and environmental flourishing.”)

ISO/IEC 14772-1, the Virtual Reality Modeling Language (VRML), defines a file format that integrates 3D graphics and multimedia. Conceptually, each VRML file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 14772 defines the interface that applications external to the VRML browser may use to access and manipulate the objects defined in ISO/IEC 14772-1. The interface described here is designed to allow an external environment to access nodes in a VRML scene using the existing VRML event model. In this model, an eventOut of a given node can be routed to an eventIn of another node. When the eventOut generates an event, the eventIn is notified and its node processes that event. Additionally, if a script in a Script node has a reference to a given node it can send events directly to any eventIn of that node and it can read the last value sent from any of its eventOuts. The scope of this standard is to cover all forms of access to a VRML browser from external applications. It is equally valid for a database with a object interface to access a standalone browser in a presentation slide as it is for a Java applet operating within a web browser and the available services do not vary. This standard does not provide a byte level protocol description as there can be many valid ways of expressing an interaction with a browser. Instead, it represents the interface in terms of the services provided and the parameters that are passed to access these services. Individual language and protocol bindings to these services are available as annexes to this part of ISO/IEC 14772.

The structure of this document is as follows. Clauses 2-4 specify the terms, abbreviations, symbols and conventions used throughout the document. Clauses 5-11 contain definitions of the description tools standardized by 15938-3 grouped by the visual features they are associated with, starting with basic structures and containers in Clause 5, through color, texture, shape, motion, localization in Clause 10. Clause 11 contains the remaining, unclassified items. Each description tool is described by the following subclauses: - Syntax: Normative DDL specification of the Ds or DSs;- Binary Syntax: Normative binary representation of the Ds or DSs; and- Semantic: Normative definition of the semantics of all the components of the corresponding D or DS.
