ISO/IEC 14496-4:2004/AMD40:2011 is a focused amendment to the conformance testing framework for audio-visual object coding, adding ExtendedCore2D conformance material to the parent document ISO/IEC 14496. For engineering, testing, and compliance teams, it is relevant when documented evaluation must reflect a specific change to the underlying test requirements rather than the base text alone. ISO/IEC 14496-4:2004/AMD40:2011 helps support technical review, verification activities, and conformity assessment preparation where version control and precise reference handling matter.

ISO/IEC 14496-4:2004/AMD40:2011 standard overview

This amendment modifies the conformance testing part of the audio-visual object coding series and is intended to be used together with the parent reference. Its scope is centered on ExtendedCore2D conformance, so it is most useful when a team needs to confirm whether implementations align with the amended test criteria and related evaluation logic. In quality workflows, the document can serve as a controlled compliance reference for laboratory evaluation, engineering documentation, and technical validation of coded media functionality.

Applications of ISO/IEC 14496-4:2004/AMD40:2011

Organizations may use ISO/IEC 14496-4:2004/AMD40:2011 during codec verification, product evaluation, and internal test planning for audio-visual systems that depend on the ISO/IEC 14496 series. It is especially relevant for teams maintaining test suites, preparing procurement reviews, or checking whether an implementation should be assessed against an amended conformance path. In practice, it supports documented evaluation in development labs, certification-oriented testing workflows, and technical assessment activities where consistent interpretation of the parent standard is required.

Why ISO/IEC 14496-4:2004/AMD40:2011 matters

Using the correct amendment reduces risk in compliance work by ensuring that conformance testing is aligned with the intended revision level. That matters for interoperability, quality assurance, and engineering validation, particularly when results are used to justify product acceptance or technical conformity. For procurement and regulatory preparation, ISO/IEC 14496-4:2004/AMD40:2011 provides the traceability needed to confirm that the referenced test basis matches the implementation under review, helping avoid ambiguity in acceptance criteria and documented evaluations.

  • Supports amended conformance testing for ExtendedCore2D within the ISO/IEC 14496 framework.
  • Useful for controlled technical review and laboratory evaluation of implementation results.
  • Helps maintain traceable compliance workflows when the parent document alone is not sufficient.
  • Relevant for procurement, certification support, and conformity assessment documentation.
