Abstract
A method of decoding a coding unit of a coding tree from a coding tree unit of an image frame from a video bitstream, the coding unit having a primary colour channel and at least one secondary colour channel. The method comprises determining a coding unit including the primary colour channel and the at least one secondary colour channel according to decoded split flags of the coding tree unit; decoding a first index to select a kernel for the primary colour channel and a second index to select a kernel for the at least one secondary colour channel; selecting a first kernel according to the first index and a second kernel according to the second index; and decoding the coding unit by applying the first kernel to residual coefficients of the primary colour channel and the second kernel to residual coefficients of the at least one secondary colour channel.
