Multimedia systems and equipment - Colour measurement and management - Part 12-2: Simple metadata format for identification of colour gamut

IEC 61966-12-1:2014(en) specifies the colour gamut metadata format for video systems intended for use in CE (Consumer Electronics) devices. The metadata specified in this part of IEC 61966 is limited to the gamut description of additive three primary colours type displays whose white and black points have the same chromaticity. It is fundamentally based on the conventional VESA-EDID format.

Systèmes et équipements multimédias - mesure et gestion de couleur - Partie 12-2: format de métadonnées simple pour l'identification de la gamme de couleurs

L'IEC 61966-12:2014 spécifie le format des métadonnées des gammes de couleurs pour les systèmes vidéo destinés à être utilisés dans les dispositifs électroniques grand public (EGP). Les métadonnées spécifiées dans la présente partie de l'IEC 61966 se limitent à la description des gammes de couleurs des écrans à trois couleurs primaires additives dont les points blancs et noirs ont la même chromaticité. Elles reposent essentiellement sur le format conventionnel VESA-EDID. Lorsqu'il est associé au contenu, le format simple des métadonnées définit la gamme de couleurs pour laquelle le contenu a été créé. Celles-ci peuvent être utilisées par l'écran pour contrôler la reproduction des couleurs, même si la gamme de couleurs de l'écran est différente de celle du contenu. Lorsqu'il est associé à un écran, le format simple des métadonnées définit la gamme de couleurs de l'écran. Celles-ci peuvent servir pendant la création du contenu, pour permettre une meilleure reproduction des couleurs. La présente norme fournit la solution la plus simple, mais sans ambiguïté, pour les dispositifs EGP types qui reposent sur la communication d'informations de gamme de couleurs.

Večpredstavnostni sistemi in oprema - Merjenje in urejanje barv - 12-2. del: Enostavni metapodatkovni format za ugotavljanje barvne lestvice (Gamut ID) (IEC 61966-12-2:2014)

Standard EN IEC 61966-12-2 določa metapodatkovno obliko zapisa barvne lestvice za video sisteme, namenjene uporabi v napravah zabavne elektronike (CE). Metapodatki, določeni v tem delu standarda IEC 61966, so omejeni na opis lestvice za vrste zaslonov s tremi aditivnimi primarnimi barvami, katerih bele in črne točke imajo enako kromatičnost. Ta oblika zapisa v osnovi temelji na konvencionalni obliki zapisa VESA-EDID. Ko je enostavna metapodatkovna oblika zapisa povezana z vsebino, ta oblika zapisa definira lestvico, za katero je bila vsebina ustvarjena. Uporabiti jo je mogoče za nadzorovano reprodukcijo barv, tudi če se barvna lestvica zaslona razlikuje od barvne lestvice vsebine. Ko je povezana z zaslonom, enostavna metapodatkovna oblika zapisa definira barvno lestvico zaslona. S to obliko zapisa je med ustvarjanjem vsebine mogoče izboljšati reprodukcijo barv. Ta standard zagotavlja enostavno, vendar nedvoumno rešitev za običajne naprave CE, temelječe na komunikaciji informacij o barvni lestvici.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61966-12-2 has been prepared by technical area 2: Colour
measurement and management, of IEC technical committee 100: Audio, video and multimedia
