1. A method of processing multi-layer video data, the method comprising:

  • generating at least one three-dimensional (3D) lookup table for color gamut scalability, wherein the at least one 3D lookup table has a size that is different for a luma component than for each of a first chroma component and a second chroma component;

    performing color prediction using the at least one 3D lookup table to convert color data of a reference picture in a first color gamut for a lower layer of the video data to a second color gamut for a higher layer of the video data; and

    generating at least one inter-layer reference picture for the higher layer of the video data based on the converted color data.
