ISO/IEC 11172-1:1993/COR1:1996

ISO/IEC 11172-1:1993/COR1:1996 is a technical corrigendum to the information technology reference for coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s, focused here on Part 1: Systems. As a supporting document, it is used alongside the parent publication to reflect an official technical correction rather than a standalone requirement. For engineering teams, laboratories, and procurement staff, ISO/IEC 11172-1:1993/COR1:1996 helps ensure that documentation, testing, and conformity assessment activities are aligned with the corrected systems-level text.

What is ISO/IEC 11172-1:1993/COR1:1996?

This corrigendum is connected to ISO/IEC 11172 and specifically modifies the Part 1 systems framework for moving pictures and associated audio stored on digital media at up to about 1,5 Mbit/s. Its purpose is typically to clarify, correct, or refine the published text so users can rely on the most accurate version during technical review and compliance workflows. Organizations working with engineering documentation, verification activities, or product evaluation may use it to confirm that the corrected systems reference is applied consistently in specification control and test planning.

Applications of ISO/IEC 11172-1:1993/COR1:1996

ISO/IEC 11172-1:1993/COR1:1996 is relevant where teams manage archived media systems, digital storage workflows, codec-related documentation, or product requirements tied to the systems layer of MPEG-1-era implementations. It may support laboratory evaluation, documented evaluation, and technical validation when verifying conformance against the parent reference. The corrigendum is also useful in procurement and engineering review processes when a controlled technical document is needed to reduce ambiguity in system behavior, interoperability assumptions, or specification interpretation.

Why is ISO/IEC 11172-1:1993/COR1:1996 important?

Using the corrigendum version matters because even small corrections can affect technical consistency, especially when teams are preparing conformity assessment evidence or maintaining controlled design and test records. In compliance workflows, the corrected text supports more reliable technical assessment, lowers the risk of using outdated wording, and improves alignment between engineering implementation and verification activities. For organizations handling product validation or regulatory preparation, ISO/IEC 11172-1:1993/COR1:1996 helps maintain quality assurance and operational consistency across review and approval stages.

• Supporting correction for the systems part of the parent moving-picture and audio coding reference
• Useful for controlled document review, verification activities, and specification traceability
• Helps reduce ambiguity during testing workflows and conformity assessment preparation
• Relevant to engineering documentation, procurement checks, and technical validation records
