IEC 62156:2001

IEC 62156:2001 defines the technical reference for Digital video recording with video compression 12,65 mm type D-9 component format 525/60 and 625/50 (Digital S), helping engineers and procurement teams align documentation, verification activities, and product evaluation around a common format description. It is relevant when comparing recording systems, assessing compatibility, or preparing conformity assessment records for digital video equipment. For organizations working with legacy broadcast or professional video workflows, IEC 62156:2001 can support clearer technical review and more consistent compliance workflows.

Overview of IEC 62156:2001

This document is the primary technical reference for a digital video recording format based on video compression and the 12,65 mm type D-9 component format in both 525/60 and 625/50 systems. Its value lies in providing a defined basis for engineering documentation, operational consistency, and technical validation of equipment that must handle the Digital S format. In procurement and laboratory settings, it can help teams confirm that a product, subsystem, or recorded signal workflow is being assessed against the intended format reference.

Compliance applications of IEC 62156:2001

IEC 62156:2001 is commonly useful in technical assessment of digital video recorders, playback systems, and related professional media equipment where format alignment matters. It may support testing workflows for recording and reproduction behavior, documentation review during product evaluation, and regulatory preparation for devices entering controlled broadcast or production environments. Laboratories and compliance teams can use it as a reference point when checking whether equipment specifications, interface behavior, and recorded output remain consistent with the expected D-9 component format.

Importance of compliance with IEC 62156:2001

Using IEC 62156:2001 as a compliance reference helps reduce risk in engineering validation and procurement decisions by giving stakeholders a clear technical basis for comparison. It can improve testing consistency, support conformity assessment preparation, and strengthen quality workflows where digital video recording formats must be documented precisely. For manufacturers, integrators, and evaluators, aligning with the referenced format may also simplify interoperability reviews and reduce ambiguity during acceptance testing or archived media handling.
