1. A method comprising:
decoding a single information set signaled in a first portion of video data, the single information set containing a plurality of candidate sets of filter parameters, a filter parameter comprising an absolute value of the filter parameter and a sign of the filter parameter;
obtaining from the video data, for a current block, at least one index identifying one of the candidate sets of filter parameters in the single information set;
decoding the current block from a second portion of the video data different from the first portion; and
filtering the decoded current block using the candidate set of filter parameters identified by the at least one index.
