colour space encoding

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

NOTE 1 Multiple colour space encodings may 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 and 10-bit e-sRGB are different colour space encodings based on a particular RGB colour space.)

NOTE 2 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.
