This National Standard of Canada is equivalent to International Standard ISO/IEC 15938-6:2003. 1 Scope This International Standard operates on and generates conformant bit streams. This International Standard provides a specific implementation that behaves in a conformant manner. In general, other implementations that conform to ISO/IEC 15938 are possible that do not necessarily use the algorithms or the programming techniques of the reference software. The software contained in this part of ISO/IEC 15938 is known as experimentation software (XM) and is divided into five categories: a) Binary format for MPEG-7 (BiM). This software converts DDL (XML) based descriptions to the Binary
format of MPEG-7 and vice versa as explained in Clause 5 of this document. b) DDL parser and DDL validation parser. The components of this software module are specified in
Clause 6 of this document. c) Visual descriptors. This software creates standard visual descriptions from associated (visual) media
content as explained in Clause 7 of this document. 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 of this document. 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 of this document.
