1. A method, comprising:
decoding an information associated with a picture part, the information indicating for a chroma component of the picture part, a number of a plurality of refinement parameter tables associated to a cross-component refinement mode that applies to a reconstructed version of the chroma component of the picture part;
decoding for the picture part a flag indicating if at least one refinement parameter table is encoded for the chroma component of the picture part;
decoding the plurality of refinement parameter tables for the chroma component based on the decoded information and the decoded flag;
decoding at a block level of the picture part an indication of a refinement parameter table, wherein a given value of the indication indicates that the cross-component refinement mode is not applied to the reconstructed version of the chroma component of the block and the indication provides for selecting the refinement parameter table from among the plurality of refinement parameter tables when the cross-component refinement mode is applied to the reconstructed version of the chroma component of the block; and
refining, in the cross-component refinement mode, the reconstructed version of the chroma component of the block based on the indication.
