The technical architecture and details of three cross-chain approaches is described in this standard, including Centralized/Multi-signature Notary-based cross-chain technology, HTLC-based cross chain technology and Relay Chain-based cross-chain technology.
Blockchain-based digital assets exist in a specific system in the form of digitization. Considering the diversity of blockchain systems and applications, as well as the diversity of digital assets in these systems and applications, digital assets based on blockchain systems have typical characteristics such as intangibility, encryption verification mechanism, use of distributed ledgers, decentralization, consensus algorithms, etc. For better classification and management, this standard provides a unified classification method for blockchain digital assets for reference. This standard proposes the principles and methods for the classification of blockchain-based digital assets. This standard follows the principles of scientificity, systematicness and scalability, and proposes an attribute-based classification method for blockchain digital assets, whose classification attributes include technical attributes, economic attributes and legal attributes.
The data fields, types, and formats related to digital assets to improve digital asset identification efficiency are defined by this standard. Moreover, guidance for blockchain-based digital asset identification is provided by the definition and description of methods and data structures in this standard.
This standard defines an exchange model for blockchain-based digital assets. The exchange model includes operational processes, data security and information security requirements, and transaction rules. The standard also defines the general technical requirements of the exchange model and describes the entity functions in the exchange model.
- physical and material parameters of virtual or real objects expressed to support comprehensive haptic rendering methods, such as stiffness, friction and micro-textures; and
- a flexible specification of the haptic rendering algorithm itself.
It supplements other standards that describe scene or content description and information models for virtual and mixed reality, such as ISO/IEC 19775 and ISO/IEC 3721-1.
ISO/IEC 19775, X3D, defines a software system that integrates network-enabled 3D graphics and multimedia. Conceptually, each X3D application is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. ISO/IEC 19775-1:2013 defines the architecture and base components of X3D. The semantics of X3D describe an abstract functional behaviour of time-based, interactive 3D, multimedia information. ISO/IEC 19775-1:2013 does not define physical devices or any other implementation-dependent concepts (e.g. screen resolution and input devices). It is intended for a wide variety of devices and applications, and provides wide latitude in interpretation and implementation of the functionality. For example, it does not assume the existence of a mouse or 2D display device. Each X3D application:
(1) implicitly establishes a world coordinate space for all objects defined, as well as all objects included by the application;
(2) explicitly defines and composes a set of 3D and multimedia objects;
(3) can specify hyperlinks to other files and applications;
(4) can define programmatic or data-driven object behaviours;
(5) can connect to external modules or applications via programming and scripting languages;
(6) explicitly declares its functional requirements by specifying a profile; and
(7) can declare additional functional requirements by specifying components.
This recommendation identifies the functional requirements for the media processing services. In particular, the scope of this Recommendation includes functional requirements and application scenarios. Media processing services utilize a set of techniques including cloud computing, computing resource virtualization, and job queue processing to dynamically control and manage computing resources, which improves scalability, flexibility, and availability. This Recommendation specifies the functional requirements of general requirements, service provision requirements, service management requirements, security considerations, etc.
This document describes a visualization framework for data quality in analytics and machine learning. The aim is to enable stakeholders using visualization methods to assess the results of data quality measures. This visualization framework supports data quality goals.
This document is the first of a family of standards. This document provides an overview of the ISO 8000 series. The following are within the scope of this document:
(1) stating the scope of the ISO 8000 series as a whole;
(2) establishing the principles of information and data quality;
(3) describing the path to data quality;
(4) describing the structure of the ISO 8000 series;
(5) providing a summary of the content of each part in the ISO 8000 series; and
(6) establishing the relationship of the ISO 8000 series to other international standards.
This recommendation describes the scenarios, general framework, and requirements for a real-time interactive multimedia service (RIMS) under poor network conditions. The RIMS system plays an important role in many scenarios and situations, e.g., emergency relief, remote education and emergency communication. The RIMS requires providing measures for adjustment of coding parameters, including video and audio coding parameters, dynamically, and it requires setting maximal priority of audio communication under low-speed network conditions and configuring usage priority attributes to ensure that high-priority uses have priority of service over low-priority uses.
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.
This document analyses visualization elements that are key components of the interface between the physical asset and the avatar (digital replica of the physical asset).
