IEC 61966-2-4:2006

IEC 61966-2-4:2006 defines the technical basis for Colour management - Extended-gamut YCC colour space for video applications - xvYCC, supporting consistent colour handling in video systems that need wider gamut representation. For engineering teams, test labs, and procurement specialists, IEC 61966-2-4:2006 is relevant when documenting colour-related requirements, reviewing compatibility expectations, or preparing technical validation activities around video equipment and workflows. Its focus on colour management makes it useful where operational consistency and reproducible visual performance matter.

IEC 61966-2-4:2006 standard overview

The official title indicates a colour measurement and management reference centered on an extended-gamut YCC colour space for video applications. In practical terms, the document is likely used to support technical assessment of how video content and equipment represent colour information beyond conventional ranges. That makes it valuable in documented evaluation, conformity assessment, and engineering documentation for systems where colour fidelity, signalling behaviour, and interoperability need to be reviewed against a defined reference.

Applications of IEC 61966-2-4:2006

This reference is most relevant in video production chains, display technology, image processing, broadcast-related workflows, and other equipment ecosystems that handle colour encoding or colour conversion. It may also support laboratory evaluation of devices intended to process or reproduce xvYCC content, particularly during verification activities and quality workflows. Organizations involved in product evaluation or technical review can use it as a compliance reference when comparing design behaviour, analysing output consistency, or preparing procurement specifications.

Why IEC 61966-2-4:2006 matters

Using a defined reference for extended-gamut colour management helps reduce ambiguity in testing workflows and technical validation. It can improve consistency across engineering teams, laboratories, and suppliers by giving them a common basis for colour-related requirements and documentation. That is especially useful in compliance preparation, where reproducible results and traceable technical criteria support risk management, conformity assessment, and procurement review. For video systems, clarity in colour handling can also help avoid interoperability issues and performance mismatches.

• Supports technical review of extended-gamut YCC colour handling for video applications
• Useful for laboratory evaluation, verification activities, and reproducible test planning
• Provides a structured reference for engineering documentation and product evaluation
• Helps align procurement and compliance workflows around colour management requirements
