About This Item

Legal Notices*

ISO/IEC 14496-5:2001/AMD24:2009 provides a supporting amendment to the reference software framework for audio-visual object coding, specifically adding reference software for AAC-ELD. For engineering teams and evaluators, ISO/IEC 14496-5:2001/AMD24:2009 is relevant when the goal is to understand or apply the associated reference implementation in testing, verification activities, or technical review. As an amendment to the parent series, it should be used together with ISO/IEC 14496 rather than treated as a standalone coding specification.

Purpose of ISO/IEC 14496-5:2001/AMD24:2009

The purpose of ISO/IEC 14496-5:2001/AMD24:2009 is to extend the reference software component of the MPEG-4 audio-visual object coding framework with AAC-ELD support. In practical terms, it helps organizations align implementation work with the documented reference behavior used for engineering validation and conformity assessment. This can be useful during technical assessment, code review, and product evaluation where a verified software reference supports more consistent interpretation of the parent document’s coding intent.

Compliance applications of ISO/IEC 14496-5:2001/AMD24:2009

ISO/IEC 14496-5:2001/AMD24:2009 is commonly relevant in compliance workflows involving codec implementation review, laboratory evaluation, and software-based interoperability testing. Teams may use it when assessing whether an AAC-ELD-related implementation follows the intended reference approach within the broader ISO/IEC 14496 framework. It can also support procurement decisions, technical documentation, and regulatory preparation where a documented reference software artifact is needed to compare product behavior against a known baseline.

Benefits of ISO/IEC 14496-5:2001/AMD24:2009

Using ISO/IEC 14496-5:2001/AMD24:2009 can improve operational consistency by providing a recognized reference point for implementation review and testing workflows. It may reduce ambiguity during engineering validation, help teams document assumptions more clearly, and support repeatable verification activities across development and quality assurance phases. For organizations managing compliance, it can also assist with risk management by giving reviewers a structured basis for technical evaluation and conformity assessment preparation.

  • Reference software amendment tied to the ISO/IEC 14496 family for AAC-ELD support
  • Useful for implementation comparison, technical review, and verification activities
  • Supports conformity assessment, documentation control, and testing consistency
  • Relevant to software teams working on codec evaluation or interoperability checks
