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.
