Web 4.0 and virtual worlds

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.

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.

This document describes the architecture of systems for the internet of media things.

This recommendation specifies requirements of 3D digital human system based on smart mobile devices from the dimensions of functional requirements, performance requirements and system requirements according to subjective and objective metrics. The evaluation methods of some unique requirements for 3D digital human and SMD application are also described. This recommendation applies to 3D digital human system based on smart mobile devices, including but not limited to smart phone assistants, e-commerce anchors, intelligent customer service, weather anchors, digital employees, etc.

This draft Recommendation describes the general access interface framework, including interface module description, application scenarios etc. It defines unified access interface requirements of digital human services for the developers to integrate the capabilities of digital human into different applications.

Under the stimulation of the concept of the metaverse, digital human is accelerating from technological innovation to industrial application. However, in the actual project implementation, most enterprises do not have the ability to directly develop and maintain digital human, so they often encounter the problems of high technical threshold, complex installation and deployment, and high management and maintenance cost. Therefore, there is a strong demand for reducing the cost of using digital human and simplifying the construction and operation and maintenance of digital human. By providing the service of creating, managing and maintaining enterprise-level digital human applications, digital human platform can help users reduce the development and use costs, and become an important way of digital human development, deployment, operation and maintenance. However, there are many kinds of digital human platforms on the market, and their quality is uneven. From service support to code implementation, there are huge differences. Therefore, the functionality, compatibility, reliability, scalability, time response, and ease of use of the platform need to be strictly tested and verified before large-scale deployment to the production environment. In addition, at present, the standard of requirement and test method of digital human platform is still blank. The purpose of this Recommendation is to provide technical guidance and technical specification support for the research and development, selection and testing of digital human platform, to achieve a fair, just, scientific and objective evaluation of digital human platform, and to promote the progress of digital human technology products. This Recommendation provides the requirements and evaluation methods for the digital human platform from the aspects of function, compatibility, reliability, scalability, time response, and ease of use.

This recommendation describes the concept, use cases and requirements of communication services for digital human. The scope of this recommendation includes:(a) Use cases of the communication services for digital human,(b) Requirements on the user interface for those who are creating digital humans, and(c) Requirements on the digital human creation and utilization procedures.

Media services by using digital human technology covers a wide range of application scenarios. Also, it involves a variety of key technologies, such as modeling, animation and rendering technologies. In order to meet high fidelity, real-time and high concurrency requirements for digital human services, this new work item is to propose new additional multimedia-based functional capabilities for cloud and edge computing platforms for various media services by using the existing digital human technology. This Recommendation describes typical use cases and specifies requirements for this platform including requirements for the multimedia processing, interaction and management function. And a user-eage-cloud media service platform based on requirements and existing technologies of cloud-edge computing and digital human for media service providers as a reference.

Recommendation ITU-T F.748.15 specifies a framework for digital human application systems, and proposes corresponding subjective and objective metrics for the dimensions of image, speech, animation, interactive processing and multimodal input/output. This Recommendation can be used to guide relevant parties to test, select or evaluate a digital human application system. The metrics can reflect the current state of the digital human application system by providing meaningful comparison dimensions.

This recommendation specifies the framework and requirements for the construction of 3D intelligent driven digital human application system based on multimedia services. The scope of this Recommendation includes:(a) Overview of 3D intelligent driven digital human application system.(b) Framework of 3D intelligent driven digital human application system.(c) Requirements of 3D intelligent driven digital human application system.
