Standard

Measuring quality of experience (QoE) aims to explore the factors that contribute to a user's perceptual experience including human, system, and context factors. Since QoE stems from human interaction with various devices, the estimation should be started by investigating the mechanism of human visual perception. Therefore, measuring QoE is still a challenging task. In this standard, QoE assessment is categorized into two subcategories which are perceptual quality and virtual reality (VR) cybersickness. In addition, deep learning models considering human factors for various QoE assessments are covered, along with a reliable subjective test methodology and a database construction procedure.

This standard defines a framework for the Tactile Internet, including descriptions of various application scenarios, definitions and terminology, functions, and technical assumptions. This framework prominently also includes a reference model and architecture, which defines common architectural entities, interfaces between those entities, and the mapping of functions to those entities. The Tactile Internet encompasses mission critical applications (e.g., manufacturing, transportation, healthcare and mobility), as well as non-critical applications (e.g., edutainment and events).

This standard specifies the general technical framework, components, integration, and main business processes of augmented reality systems applied to mobile devices, and defines its technical requirements, including functional requirements, performance requirements, safety requirements and corresponding test methods. This standard is applicable to the design, development, and management of augmented reality enabled applications or features of applications on mobile devices.

This standard defines an architecture required to implement a virtual reality system that can simulate responses to possible disasters in physical spaces, where users can actually move around with six degrees of freedom, for training. This reference architecture includes the physical-to-virtual component that transfers sensor data in the physical space to the virtual world, the virtual-to-virtual component that conveys the data between virtual world objects, and the virtual-to-physical component that transfers the simulated responses in the virtual world to actuators in the physical world.

This standard specifies the requirements and test methods for the motion to photon (MTP) latency that causes virtual reality (VR) sickness while users are using the virtual reality content. This standard is applicable to VR content related with software, hardware, and human factors regarding MTP latency.

This standard specifies a functional architecture that supports the energy-efficient transmission and processing of large volumes of data, starting at processing nodes close to the data source, with significant processing resources provided at centralized data centers.

ISO/IEC 18023-2:2006 specifies the abstract syntax of a SEDRIS transmittal. Actual encodings (e.g. binary encoding) are specified in other parts of ISO/IEC 18023.

This document specifies the abstract class of a media thing (MThing), which is a basic component to construct the Internet of media things. The MThing class contains the basic APIs to:(a) discover other MThing(s) in the network;(b) connect/disconnect MThing(s); and(c) support transactions (e.g. payments) using media tokens between MThings.

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.
