7、ardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of
8、 mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this docume
9、nt and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Par
10、t 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the developm

This third edition cancels and replaces the second edition (ISO/IEC 23005-6:2013), which has been technically revised. ISO/IEC 23005 consists of the following parts, under the general title Informati

15、16(E) ISO/IEC 2016 All rights reserved v Introduction ISO/IEC 23005 (MPEG-V) provides an architecture and specifies associated information representations to enable interoperability between virtual worlds, e.g. digital content provider of a virtual world, gaming (serious), simulation, DVD, and with
16、the real world, e.g. sensors, actuators, vision and rendering, robotics (e.g. for revalidation), (support for) independent living, social and welfare systems, banking, insurance, travel, real estate, rights management and many others. Virtual worlds (often referred to as 3D3C for 3D visualization an
17、d navigation and the 3Cs of Community, Creation and Commerce) integrate existing and emerging (media) technologies (e.g. instant messaging, video, 3D, VR, AI, chat, voice, etc.) that allow for the support of existing, and the development of new kinds of, social networks. The emergence of virtual wor
18、lds as platforms for social networking is recognized by businesses as an important issue for at least two reasons: It offers the power to reshape the way companies interact with their environments (markets, customers, suppliers, creators, stakeholders, etc.) in a fashion comparable to the Internet.
19、It allows for the development of new (breakthrough) business models, services, applications and devices. Each virtual world, however, has a different culture and audience making use of these specific worlds for a variety of reasons. These differences in existing metaverses permit users to have uniqu
20、e experiences. Resistance to real-world commercial encroachment still exists in many virtual worlds, where users primarily seek an escape from real life. Hence, marketers should get to know a virtual world beforehand and the rules that govern each individual universe. Although realistic experiences
21、have been achieved via devices such as 3D audio/visual devices, it is hard to realize sensory effects only with the presentation of audiovisual contents. The addition of sensory effects leads to even more realistic experiences in the consumption of audiovisual contents. This will lead to the applica
22、tion of new media for enhanced experiences of users in a more realistic sense. Such new media will benefit from the standardization of control and sensory information which can include sensory effect metadata, sensory device (actuator) capabilities/commands, user sensory preferences, and various del
23、ivery formats. The MPEG-V architecture can be applicable for various business models for which audiovisual contents can be associated with sensory effects that need to be rendered on appropriate actuators. This part of ISO/IEC 23005 contains the data types and tools which are common to more than one
24、 tool defined in more than one part of ISO/IEC 23005. The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may involve the use of patents. ISO and the IEC take
25、 no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured ISO and the IEC that they are willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this resp
26、ect, the statements of the holders of these patent rights are registered with ISO and the IEC. Information may be obtained from the companies listed in Annex C. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those ident
27、ified in Annex C. ISO and the IEC shall not be held responsible for identifying any or all such patent rights.

28、C 23005 specifies syntax and semantics of the data types and tools common to the tools defined in the other parts of ISO/IEC 23005, such as basic data types which are used as basic building blocks in more than one of the tools in ISO/IEC 23005, colour-related basic types which are used in light and
29、colour- related tools to help in specifying colour-related characteristics of the devices or commands, and time stamp types which can be used in device commands, and sensed information to specify timing related information. Several classification schemes which are used in more than one part of ISO/I
30、EC 23005 are also defined in Annex A. Other tools to be developed are included in this part of ISO/IEC 23005, if those tools are to be used with the tools defined in more than one part of ISO/IEC 23005. Most of the tools defined in this part are not intended to be used alone, but to be used as a par
31、t or as a supporting tool of other tools defined in other parts of ISO/IEC 23005. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
