The standard addresses a broad spectrum of multimediaapplications and requ
29、irements by providing a metadata system for describing the features of multimedia content.The following are specified in this standard: Description Schemes (DS) describe entities or relationships pertaining to multimedia content. DescriptionSchemes specify the structure and semantics of their compon
30、ents, which may be Description Schemes,Descriptors, or datatypes. Descriptors (D) describe features, attributes, or groups of attributes of multimedia content. Datatypes are the basic reusable datatypes employed by Description Schemes and Descriptors Systems tools support delivery of descriptions, m
31、ultiplexing of descriptions with multimedia content,synchronization, file format, and so forth.This standard is subdivided into eight parts:Part 1 Systems: specifies the tools for preparing descriptions for efficient transport and storage, compressingdescriptions, and allowing synchronization betwee
32、n content and descriptions.Part 2 Description definition language: specifies the language for defining the standard set of description tools(DSs, Ds, and datatypes) and for defining new description tools.Part 3 Visual: specifies the description tools pertaining to visual content.Part 4 Audio: specif
33、ies the description tools pertaining to audio content.Part 5 Multimedia description schemes: specifies the generic description tools pertaining to multimediaincluding audio and visual content.Part 6 Reference software: provides a software implementation of the standard.Part 7 Conformance testing: sp
34、ecifies the guidelines and procedures for testing conformance ofimplementations of the standard.Part 8 Extraction and use of MPEG-7 descriptions: provides guidelines and examples of the extraction anduse of descriptions.This document specifies the Multimedia Description Schemes (MDS) part of the ISO
35、/IEC 15938 standard. Thisdocument specifies the MDS description tools and provides informative examples of descriptions. The normativesyntax of the MDS description tools is specified in this document using the Description Definition Language (DDL)and the normative semantics is specified using text.C

37、ioninterface Part 5:Multimedia description schemes1 Scope1.1 Organization of the documentThis International Standard specifies a metadata system for describing multimedia content. This documentspecifies the Multimedia Description Schemes (MDS) description tools (Description Schemes, Descriptors, and
38、datatypes) that comprise ISO/IEC 15938-5. The following set of subclauses are provided for each MDS descriptiontool, where optional subclauses are indicated as (optional): Syntax: specifies the normative syntax of the description tool using Description Definition Language (DDL) (seeISO/IEC 15938-2).
39、 Binary syntax (optional): specifies the normative binary representation for the description tool, where relevant.If a binary syntax is not specified, then the binary coding method of ISO/IEC 15938-1 shall apply for thedescription tool. Semantic: specifies the normative semantics of the description
40、tool and each of its components (attributes andelements). Informative examples (optional): provides informative examples that illustrate the use or instantiation of thedescription tool in creating descriptions.1.2 Overview of Multimedia Description SchemesThe MDS description tools are organized on t
41、he basis of functionality as shown in Figure 1.BasicDatatypes Links describepartitions, views and decompositions of image, video, and audio signals in space,time and frequency; and describe the relationships between different variations ofmultimedia content.Content organizationtools (clause 14)Speci
42、fies tools that describe the organization and modeling of multimedia content.The content organization tools include collections, probability models, analyticmodels, cluster models, and classification models.User interaction tools(clause 15)Specifies tools related to user interaction with multimedia
43、content. The userinteraction tools describe user preferences pertaining to multimedia content, anddescribe the usage history of users of multimedia content.Finally, classification schemes, which organize terms that are used by the description tools, are specified inAnnex B (Classification Schemes).2
