ISO/IEC 11172-2:1993/COR3:2003

ISO/IEC 11172-2:1993/COR3:2003 is a technical corrigendum to the video part of Information technology - Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s - Part 2: Video - Technical Corrigendum 3. It is relevant when teams need a controlled reference for reviewing, implementing, or verifying the corrected video coding requirements tied to the parent document ISO/IEC 11172. For engineering, testing, and procurement workflows, ISO/IEC 11172-2:1993/COR3:2003 helps ensure that documented evaluation and technical compliance activities are aligned with the amended text.

ISO/IEC 11172-2:1993/COR3:2003 standard overview

As a corrigendum, ISO/IEC 11172-2:1993/COR3:2003 functions as a supporting modification to the original video specification rather than a standalone technical framework. Its purpose is typically to correct, clarify, or refine the parent text so that implementation and verification work can rely on an updated reference. In practice, this matters for technical review, conformity assessment, and engineering documentation where precise interpretation of video coding requirements affects validation results and operational consistency.

Applications of ISO/IEC 11172-2:1993/COR3:2003

Organizations may use ISO/IEC 11172-2:1993/COR3:2003 when maintaining legacy digital video systems, reviewing codec-related documentation, or checking conformance against the corrected wording of the parent publication. It is useful in product evaluation, laboratory evaluation, and compliance workflows where video encoding behavior must be compared against the official reference set. The corrigendum can also support procurement and technical assessment activities when archived specifications, test plans, or engineering specifications need to reflect the corrected requirements.

Why ISO/IEC 11172-2:1993/COR3:2003 matters

This corrigendum helps reduce implementation risk by keeping the technical record aligned with the corrected video specification. For teams performing verification activities, it can improve testing consistency, support quality assurance, and strengthen conformity assessment preparation. In regulated or controlled development environments, using the updated wording may help prevent interpretation errors that could affect interoperability, documentation accuracy, or acceptance testing. ISO/IEC 11172-2:1993/COR3:2003 is therefore valuable wherever a reliable compliance reference is needed for legacy moving-picture coding work.

• Corrigendum to the video portion of the parent ISO/IEC 11172 document family.
• Useful for correcting or confirming implementation details in legacy moving-picture coding workflows.
• Supports technical review, test planning, and documented evaluation against the revised text.
• Helps align engineering documentation, procurement checks, and conformity assessment records.
