Full title and description
Video systems (525/60) - Video and accompanied data using the vertical blanking interval - Analogue interface - Part 2: 525 progressive scan system. This IEC publication specifies the analogue interface and signalling method for carrying video-related identification and copy-control data in the vertical blanking interval (VBI) of 525 progressive-scan (480p) video systems.
Abstract
IEC 61880-2:2002 defines how video-associated data (such as aspect-ratio identification and copy-control information) is encoded and transmitted in the vertical blanking interval of 525/60 progressive-scan analogue video signals. It complements the base IEC 61880 specification for 525/60 systems by addressing requirements specific to progressive-scan operation and the analogue interface used to carry accompanying data in VBI lines.

Scope
This part of IEC 61880 applies to the analogue interface for 525/60 progressive-scan video systems and specifies the structure, bit assignment and method of transfer of identification and copy-control codes in the vertical blanking interval (VBI) of the luminance signal. It is intended for use where accompanying data must travel with an analogue 525 progressive-scan (480p) video signal and aligns with CGMS‑A copy‑management signalling concepts used for analogue video.
Key topics and requirements
- Definition of VBI line usage and timing for 525 progressive-scan analogue signals.
- Bit and code assignments for identification data words transmitted in VBI.
- Specification of copy-control information encoding suitable for CGMS‑A style signalling in 480p/525 progressive systems.
- Construction rules for identification signals and CRC/error-checking fields.
- Normative requirements for interoperability of analogue equipment carrying accompanying data in the VBI.
Technical details and normative assignments are specified in the standard body and normative annexes.
Typical use and users
Manufacturers of video equipment (analogue/digital interfaces), broadcast engineers, chipset and display-driver developers, system integrators for video distribution and archiving, and organizations implementing copy‑management signaling (CGMS‑A) in environments using 525/60 progressive-scan signals. It's used when analogue VBI channels must carry metadata, aspect-ratio flags, or copy-control flags interoperably between devices.
Related standards
IEC 61880 (base publication covering 525/60 analogue VBI signalling), other parts of the IEC 61880 series where applicable, and related regional standards for copy management and VBI data (for example standards covering CGMS‑A implementations and 625/50 equivalents such as IEC 62375). Implementers should also consult TC 100 work items for multimedia signalling and national adoptions where relevant.

FAQ
Q: What is this standard?
A: IEC 61880-2:2002 is Part 2 of the IEC 61880 series that specifies how video-associated data and copy-control information are encoded in the vertical blanking interval of 525/60 progressive-scan (480p) analogue video signals.
Q: What does it cover?
A: It covers the analogue interface definitions, the structure and bit assignments of identification and copy-control words transmitted in the VBI for 525 progressive-scan systems, including CRC/error checking and timing/line usage rules.
Q: Who typically uses it?
A: Video equipment manufacturers, broadcast and AV system engineers, chipset and driver developers, and anyone implementing CGMS‑A style copy‑control or embedding metadata in analogue VBI for 525/60 progressive systems.
Q: Is it current or superseded?
A: The publication date is 20 September 2002 and it is listed as the published edition; catalogues and national standards bodies list it as the active/valid edition. Users should check national adoption and any newer TC 100 outputs for updates or regional replacements when planning compliance.
Q: Is it part of a series?
A: Yes — IEC 61880 is a series addressing video systems (525/60) and VBI-based accompanying-data signalling; Part 1 covers the base analogue interface and other parts address specific signal formats such as progressive-scan (Part 2). Implementers should review the other parts of IEC 61880 for complementary requirements.
