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.
