An appropriate first post on this list. Let the technical MPEG-7 discussions begin! Best, Rob -----Original Message----- From: Rehatschek, Herwig [mailto:Herwig.Rehatschek@joanneum.at] Sent: Tuesday, 3 February 2024 09:23 To: mp7a_news@yahoogroups.com Subject: [mp7a_news] Free MPEG-7 library available from JOANNEUM RESEARCH ---------------------------------------------------- Free MPEG-7 library available from JOANNEUM RESEARCH ---------------------------------------------------- The MPEG-7 ISO standard to describe multimedia objects is an important prerequisite to interoperability and openness of applications and content. In the course of a series of projects, partially funded by the European Commission and by national research programs, JOANNEUM RESEARCH has developed a C++-implementation of the full MPEG-7 standard ISO/IEC 15938:2001. To promote the uptake of MPEG-7, JOANNEUM RESEARCH offers its MPEG-7 library for fee-free use. It is available for download under: http://iis.joanneum.at/MPEG-7 If you want to deal with MPEG-7 metadata, and if you do not want to struggle with complex XML DOM programming, you will benefit from our solution. MPEG-7 metadata, which are stored in a hierarchical XML representation, are made available in an object oriented hierarchical class tree. The JRS MPEG-7 library avoids the time consuming task of having to implement hundreds of necessary MPEG-7 classes before implementation of MPEG-7 functionality can start. Application developers can create and manipulate multimedia content descriptions with this library. It allows them to serialize metadata to XML and to de-serialize them - with validation - from XML. Target operating systems are Windows and UNIX systems. One major design goal was to provide simple techniques for the extension of classes. This allows the developer to enrich interface functionality for certain descriptors. Furthermore documentation on concept and source code level improves the learning curve for the programmer.

I wanted to know if MPEG-7 is backward compatible. What I wanted to know is, will a MPEG-7 decoder be able to decode a MPEG-2 or MPEG-4 video file? Because of the apparent view that MPEG-7 is a Multimedia content description standard, as against a standard which deals with coding of motion pictures and audio as other MPEGs, I am kind of confused if a MPEG-7 decoder can decode prior MPEG formats. In essence, what I see is MPEG-7 is not a superset of its predecessors. Can someone clear this up for me. Thanks in advance.

The data that MPEG-7 represents can arguably be described as 'metadata'. MPEG-7 does not seek to represent the pixels and waveforms with a representation purpose. So the answer is that MPEG-7 is not backward compatible inthe sense that the MPEG-7 standard does not defie and bitstream decoding tools that are even similar to the ones in MPEG-2 and MPEG-4.
