Full title and description

ISO/IEC 14496-4:2004/Amd 1:2005/Cor 1:2005 — Information technology — Coding of audio‑visual objects — Part 4: Conformance testing; Amendment 1 (2005) with Technical Corrigendum 1 (2005). This item updates the Part 4 conformance test specifications for MPEG‑4 implementations to include the Amendment and its Corrigendum.

Abstract

This publication is an amendment and associated corrigendum to ISO/IEC 14496‑4 (MPEG‑4 Part 4 — Conformance testing). It defines additional or corrected conformance test requirements, test vectors and reporting details intended to ensure consistent interoperability of MPEG‑4 implementations and to supplement the 2004 edition of Part 4.

Scope

The document amends ISO/IEC 14496‑4 (Part 4: Conformance testing) to add, modify or correct conformance test specifications for MPEG‑4 systems and related profiles. Its scope includes definitions of new or revised test cases, clarifications to test methodologies and any required changes to conformance reporting so that implementers and test laboratories can verify compliance with MPEG‑4 conformance requirements.

Key topics and requirements

• Specification of additional or revised conformance test cases and test vectors for MPEG‑4 implementations.
• Clarifications and corrections to test procedures and expected results to remove ambiguity in conformance evaluation.
• Updates to conformance reporting formats and required conformance statements.
• Compatibility and interoperability considerations for implementations following the 2004 Part 4 text plus the 2005 amendment and corrigendum.
• References to normative text in ISO/IEC 14496 Part 4 and cross‑references to other MPEG‑4 parts where relevant.

Typical use and users

Primary users are product implementers (codec and systems developers), independent test laboratories and conformance‑test tool vendors who must verify that MPEG‑4 systems implementations meet the published conformance criteria. Secondary users include standards bodies, certification authorities, integrators and QA teams responsible for interoperability testing.

Related standards

Closely related items include other parts of the ISO/IEC 14496 (MPEG‑4) suite — notably Part 1 (Systems), Part 2 (Visual), Part 3 (Audio) and subsequent amendments/corrigenda to Part 4. Later corrigenda and amendments to Part 4 (for example additional corrigenda after 2005) and newer editions of Part 4 should be consulted for the most up‑to‑date conformance requirements.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2005) and Technical Corrigendum 1 (2005) to ISO/IEC 14496‑4:2004 — the Part of the MPEG‑4 family that defines conformance testing requirements for MPEG‑4 implementations.

Q: What does it cover?

A: It covers additions, corrections and clarifications to the conformance test specifications for MPEG‑4 systems, including new or revised test cases, expected results and reporting requirements used by conformance test labs and tool vendors.

Q: Who typically uses it?

A: Codec and systems implementers, independent test laboratories, conformance tool developers, QA and interoperability teams, and standards/certification bodies that verify MPEG‑4 compliance.

Q: Is it current or superseded?

A: The Amendment 1 and Corrigendum 1 documents were published in 2005 (Amendment in April 2005; Corrigendum on 18 August 2005). They amend the 2004 edition of Part 4. Users should check the latest edition and any subsequent amendments or corrigenda to ISO/IEC 14496‑4 to confirm the current normative text before performing certification or testing.

Q: Is it part of a series?

A: Yes — it is part of ISO/IEC 14496 (the MPEG‑4 series). Part 4 is the conformance testing part and is published alongside other parts (Systems, Visual, Audio, etc.) and their respective amendments and corrigenda.

Q: What are the key keywords?

A: MPEG‑4, conformance testing, conformance suite, test vectors, amendment, corrigendum, ISO/IEC 14496‑4, interoperability.
