Device and method for decoding video data

An electronic device for decoding video data, the electronic device comprising:

• at least one processor;
• and
• one or more non-transitory computer-readable media coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the electronic device to:
• receive the video data;
• determine a block unit from a current frame included in the video data;
• determine an extrapolation merge list of the block unit, the extrapolation merge list including a plurality of extrapolation merge candidates, wherein each of the plurality of extrapolation merge candidates includes a plurality of previous extrapolation parameters used to reconstruct a corresponding one of a plurality of extrapolation-reconstructed blocks;
• select an extrapolation reference candidate from the plurality of extrapolation merge candidates for the block unit, wherein the extrapolation reference candidate is one of the plurality of extrapolation merge candidates;
• determine an extrapolation prediction filter of the block unit based on the extrapolation reference candidate;
• and
• reconstruct the block unit based on the extrapolation prediction filter.
