About This Item

Legal Notices*

ISO/IEC 14496-4:2004/AMD4:2005 is a supporting amendment to the coding of audio-visual objects conformance testing framework, adding IPMPX conformance extensions to the parent document ISO/IEC 14496-4. It is relevant where engineering teams, test laboratories, and compliance reviewers need to verify that implementations align with the amended conformance requirements. For organizations handling product evaluation, technical validation, or documented evaluation of MPEG-related systems, this amendment helps clarify how the modified conformance scope should be applied in a controlled workflow.

What is ISO/IEC 14496-4:2004/AMD4:2005?

This amendment modifies the conformance testing provisions associated with ISO/IEC 14496-4, focusing on IPMPX conformance extensions. In practical terms, it serves as a technical update that must be read together with the parent reference when reviewing compliance obligations, verification activities, or test planning. ISO/IEC 14496-4:2004/AMD4:2005 is therefore useful for teams that need to assess whether an implementation meets the revised conformance rules without relying on assumptions from the base text alone.

Applications of ISO/IEC 14496-4:2004/AMD4:2005

Typical use includes conformance assessment, laboratory evaluation, and internal technical review for audio-visual coding implementations that reference the MPEG framework. It may support procurement teams and engineering groups that need a compliance reference during vendor evaluation, product acceptance, or certification preparation. Because it is an amendment to the existing conformance testing structure, ISO/IEC 14496-4:2004/AMD4:2005 is generally consulted alongside related engineering documentation, test procedures, and validation records rather than as a standalone procurement basis.

Why is ISO/IEC 14496-4:2004/AMD4:2005 important?

The value of this amendment lies in helping organizations maintain testing consistency and operational consistency when applying updated conformance requirements. For teams responsible for conformity assessment, it can reduce ambiguity in technical assessment and support more reliable verification activities. ISO/IEC 14496-4:2004/AMD4:2005 also helps align quality workflows and regulatory preparation by providing a documented basis for interpreting the amended test scope, which is important when comparing implementations, managing risk, or preparing formal compliance evidence.

  • Supports conformance testing activities connected to the parent ISO/IEC 14496-4 framework
  • Provides IPMPX conformance extensions for updated technical review and validation work
  • Useful for laboratories, implementers, and compliance teams preparing test evidence
  • Helps keep engineering documentation aligned with the amended conformity requirements
