About This Item

Legal Notices*

ISO/IEC 14496-4:2004/AMD26:2008 is an amendment to the conformance-testing framework in ISO/IEC 14496, addressing conformance levels and bitstreams for Open Font Format within the broader coding of audio-visual objects series. For teams responsible for technical review, procurement, or conformity assessment, it helps clarify how implementation behavior is evaluated against defined test content. ISO/IEC 14496-4:2004/AMD26:2008 is most relevant when documented evaluation and verification activities need to follow the parent reference with an updated compliance reference.

ISO/IEC 14496-4:2004/AMD26:2008 standard overview

This amendment supports the conformance-testing part of ISO/IEC 14496 by refining the testing context for Open Font Format bitstreams and conformance levels. As a modifying document rather than a standalone technical specification, it is typically used alongside the parent framework during engineering documentation and technical assessment. Organizations may use it to align laboratory evaluation, implementation checks, and quality workflows with the amended test conditions described by the reference code and official title.

Applications of ISO/IEC 14496-4:2004/AMD26:2008

Typical use cases include product evaluation, implementation validation, and conformance assessment activities where Open Font Format-related bitstreams must be checked against a defined testing basis. It may be relevant to development teams, test laboratories, and compliance groups working on digital media systems, authoring tools, or software components that process font-related data within audio-visual object workflows. In procurement and regulatory preparation, the amendment can support clearer technical review of what evidence is needed for documented compliance.

Why ISO/IEC 14496-4:2004/AMD26:2008 matters

By updating the conformance-testing content connected to ISO/IEC 14496, this amendment helps reduce ambiguity in verification activities and supports more consistent test outcomes. That can improve interoperability, quality assurance, and risk management when organizations compare implementations against the same reference basis. For compliance teams, it may also simplify conformity assessment preparation by aligning engineering validation with a more specific set of conformance levels and bitstream expectations. ISO/IEC 14496-4:2004/AMD26:2008 is therefore useful where technical consistency and traceable evaluation are priorities.
