Abstract
Described are systems and methods for encoding or decoding a picture part of video information can include using a refinement mode per block where the refinement mode can be based on a refinement parameter. The refinement mode can include a cross-component refinement that can be a cross-component chroma refinement. The refinement mode can include enabling selection per block of a refinement parameter where the refinement parameter can include one or more chroma refinement parameters included in a chroma refinement table.

A method, comprising:
- decoding at a block level of a picture part, an indication providing for selecting for a block, a refinement parameter table from among a plurality of refinement parameter tables associated to a component refinement mode that applies to a reconstructed version of a component of the picture part;
- obtaining one or more refinement parameters for the block using the selected refinement parameter table;
- and
- refining the picture part in the component refinement mode, wherein the component refinement mode is applied to the block of the picture part based on the obtained one or more refinement parameters.
An apparatus comprising one or more processors configured to:
- decode at a block level of a picture part, an indication providing for selecting for a block, a refinement parameter table from among a plurality of refinement parameter tables associated to a component refinement mode that applies to a reconstructed version of a component of the picture part;
- obtain one or more refinement parameters for the block using the selected refinement parameter table;
- and
