IEC 61966-2-4:2006+A1:2016 is applicable to the encoding and communication of YCC colours used in video systems and similar applications by defining encoding transformations for use in defined reference capturing conditions. If actual conditions differ from the reference conditions, additional rendering transformations may be required. Such additional rendering transformations are beyond the scope of this standard. This bilingual version (2013-02) corresponds to the monolingual English version, published in 2006-01. This consolidated version consists of the first edition (2006) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.
