Natio
9、nal 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 mutual interest.
10、 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. International Standards are drafted in accordance with the
11、rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires
12、approval by at least 75 % of the national bodies casting a vote. 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. ISO/IEC 23005-3 was prepared
13、 by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. This third edition cancels and replaces the second edition of ISO/IEC 23005-3:2013 which has been technically revised. It also incorporates ISO/IE
14、C 23005-3:2013/Cor.1:2013. ISO/IEC 23005 consists of the following parts, under the general title Information technology Media context and control: Part 1: Architecture Part 2: Control information Part 3: Sensory information Part 4: Virtual world object characteristics Part 5: Data formats for inter
15、action devices Part 6: Common types and tools Part 7: Conformance and reference software ISO/IEC 23005-3:2016(E) vi ISO/IEC 2016 All rights reserved Introduction ISO/IEC 23005 (MPEG-V) provides an architecture and specifies associated information representations to enable interoperability between vi
16、rtual worlds, e.g. digital content provider of a virtual world, (serious) gaming, simulation, DVD, and with 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
17、estate, rights management and many others. Virtual worlds (often referred to as 3D3C for 3D visualization & 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 t
18、he support of existing, and the development of new kinds of, social networks. The emergence of virtual worlds 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 environmen
19、ts (markets, customers, suppliers, creators, stakeholders, etc.) in a fashion comparable to the Internet. 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 speci
20、fic worlds for a variety of reasons. These differences in existing metaverses permit users to have unique 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 virt
21、ual world beforehand and the rules that govern each individual universe. Although realistic experiences have been achieved via devices such as 3-D audio/visual devices, it is hard to realize sensory effects only with the presentation of audiovisual contents. The addition of sensory effects leads to
22、even more realistic experiences in the consumption of audiovisual contents. This will lead to the application 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 ef
23、fect metadata, sensory device capabilities/commands, user sensory preferences, and various delivery 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 sensory dev
24、ices. This part of ISO/IEC 23005 contains the sensory information which can stimulate other senses than vision or audition, e.g. olfaction, mechanoreception, equilibrioception, or thermoception. That is, in addition to the audio-visual content of, e.g., a movie, also other sense shall be stimulated
25、giving her/him the sensation of being part of the particular media which shall result in a worthwhile, informative user experience. The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that comp
26、liance with this document may involve the use of patents. ISO and the IEC take 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-discrimi
27、natory terms and conditions with applicants throughout the world. In this respect, the statements of the holders of these patent rights are registered with ISO and the IEC.

29、/IEC 2016 All rights reserved 1 Information technology Media context and control Part 3: Sensory information 1 Scope This Part of ISO/IEC 23005 specifies syntax and semantics of description schemes and descriptors that represent sensory information. This international standard is applicable to enhan
30、ce the experience of users while consuming media resources by stimulating human multi-sensor such as tactile, orfactory, light sense, temperature sense, etc. The system architecture is depicted in Figure 1 and the scope of this Part of ISO/IEC 23005 is highlighted. That is, only the information repr
31、esentation that acts as an input to the possible Adaptation VR as defined in ISO/IEC 23005-1 is specified in this Part of ISO/IEC 23005. The adaptation engine for Sensory Information is to adapt Sensory information to Device Command which is the actual signal to control multi-sensory devices as defi
32、ned in ISO/IEC 23005-5. This adaptation process is not mandatory incase the sensory information may directly control the actual devices. NOTE 1 The actual Adaptation VR is deliberately informative and left open for industry competition. Figure 1 System Architecture NOTE 2 Additional informative info

42、information according to the capabilities of real world devices or the preferences of the user. A specification of these capabilities and preferences can be found in ISO/IEC 23005-2. 3.2 Abbreviated terms For the purpose of this document, the abbreviated terms given in the following apply: DIA digit

In some cases though, and in particular for Clause 5,
45、 the syntax of description schemes and descriptors is provided as a collection of schema snippets imbricated with other text. In order to form a valid schema document, these schema components should be gathered in a same document with the schema wrapper provided at the head of the clause. For better
46、 readability, the relevant schema documents are provided in Annex B, but as non-normative information. In all cases, each schema document has a version attribute, the value of which is “ISO/IEC 23005-3“. Furthermore, an informative identifier is given as the value of the id attribute of the schema c
47、omponent. This identifier is non-normative and used as a convention in this specification to reference another schema document. In particular, it is used for the schemaLocation attribute of the include and import schema components. 3.4 Use of prefixes For clarity, throughout this Part of ISO/IEC 230
48、05, consistent namespace prefixes are used. “xsi:“ prefix is not normative. It is a naming convention in this document to refer to an element of the http:/www.w3.org/2001/XMLSchema-instance namespace. “xml:“ and “xmlns:“ are normative prefixes defined in 1. The prefix “xml:” is by definition bound t
49、o “http:/www.w3.org/XML/1998/namespace“. The prefix “xmlns:” is used only for namespace bindings and is not itself bound to any namespace name. All other prefixes used in either the text or examples of this specification are not normative, e.g., “sedl:”, “sev:”, “dia:”, “si:”, “mpeg7:”.
