ISO/IEC 21000-4:2006/COR1:2012 is a corrigendum to the MPEG-21 framework for multimedia, specifically the Intellectual Property Management and Protection Components described in Part 4. It matters for teams that rely on accurate technical documentation because corrigenda are used to correct, refine, or clarify the underlying reference. For engineering, procurement, and compliance workflows, ISO/IEC 21000-4:2006/COR1:2012 helps ensure that documented evaluation and technical review are based on the corrected text rather than an unamended version.

Purpose of ISO/IEC 21000-4:2006/COR1:2012

The purpose of ISO/IEC 21000-4:2006/COR1:2012 is to support the parent MPEG-21 Part 4 document by issuing a technical correction to the Intellectual Property Management and Protection Components framework. In practice, that makes it a supporting reference for organizations performing technical assessment, conformity assessment, or specification review. When a team is validating implementation requirements, updating engineering documentation, or checking a compliance reference set, the corrigendum helps keep the document basis aligned with the corrected published content.

Compliance applications of ISO/IEC 21000-4:2006/COR1:2012

Organizations may use ISO/IEC 21000-4:2006/COR1:2012 during product evaluation, standards traceability checks, and regulatory preparation for multimedia systems that reference MPEG-21 intellectual property management and protection concepts. It is particularly relevant where documented evaluation depends on the exact wording of the parent specification and its correction record. For procurement teams and laboratories, the corrigendum can be part of a controlled technical document set used in verification activities, testing workflows, and quality workflows that require operational consistency.

Benefits of ISO/IEC 21000-4:2006/COR1:2012

Using ISO/IEC 21000-4:2006/COR1:2012 can reduce interpretation risk by directing users to the corrected technical text associated with the parent document. That supports more reliable technical validation, stronger compliance workflows, and cleaner procurement review when a project depends on precise multimedia framework references. It also helps improve consistency across engineering documentation, testing records, and conformity assessment preparation, which is valuable when organizations need a stable basis for internal review or external audit.
