Definition: digital encoding of a colour space, including the specification of a digital encoding method, and an encoding range

Note 1 to entry: Multiple colour space encodings can be defined based on a single colour space where the different colour space encodings have different digital encoding methods and/or encoding ranges. (For example, 8-bit sRGB in accordance with IEC 61966-2-1, Multimedia systems and equipment – Colour measurement and management – Part 2-1: Colour management – Default RGB colour space – sRGB and 16-bit scRGB in accordance with IEC 61966-2-2, Multimedia systems and equipment – Colour measurement and management – Part 2-2: Colour management – Extended RGB colour space – scRGB are different colour space encodings based on a particular RGB colour space.)

Note 2 to entry: A colour space encoding is defined with a number of colour channels, each channel corresponding to one dimension of the colour space. Encoded colour channel data values indicate a position along the corresponding dimension in the geometric colour space representation.
