Abstract
A method for determining a luminance value used to process color samples in a decoder or encoder is provided comprising determining (33, 44) a luminance sample associated with a chroma sample position in a common space; and applying (34, 492) the determined luminance sample in a process that depends on luminance that is being applied to the chroma sample.
