Preface:
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Standard supersedes CSA ISO/IEC 15938-6:04 (adopted ISO/IEC 15938-6:2003). At the time of publication, ISO/IEC 15938-6:2020 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope:
The ISO/IEC 15938 series operates on and generates conformant bitstreams. This document provides a specific implementation that behaves in a conformant manner.
NOTE 1 Other implementations that conform to the ISO/IEC 15938 series are possible, which do not necessarily use the algorithms or the programming techniques of the reference software.
The software contained in this document is known as eXperimentation Model (XM) and is divided into five categories:
a) Binary format for MPEG-7 (BiM). This software converts DDL (XML) based descriptions to binary format and vice versa as explained in Clause 5.
b) DDL parser and DDL validation parser. The components of this software module are specified in Clause 6.
c) Visual descriptors. This software creates standard visual descriptions from associated (visual) media content as explained in Clause 7.
NOTE 2 The techniques used for extracting descriptors are informative, and the quality and complexity of these extraction tools has not been optimized.
d) Audio descriptors. This software creates standard descriptions from associated (audio) media content as explained in Clause 8.
NOTE 3 The techniques used for extracting descriptors are informative, and the quality and complexity of these extraction tools has not been optimized.
e) Multimedia description schemes. This software modules provide standard descriptions of multimedia description schemes as specified in Clause 9.
