Claim 15:
16. The electronic device of claim 14, wherein in the determining a BDOF offset without performing any right shifting using the shifted pair of refinement parameters, the at least one memory stores further program code that is executed by the at least one processor to perform operations comprising determining the BDOF offset in accordance with:

bdofOffset=(vx*(gradientHL0[x+1][y+1]−gradientHL1[x+1][y+1]))+(vy*(gradientVL0[x+1][y+1]−gradientVL1[x+1][y+1]))

where bdofOffset is the bidirectional optical flow offset BDOF offset, vx is the first refinement parameter having an added offset, vy is the second refinement parameter having an added offset, gradientHL0[x+1][y+1] is the first horizontal gradient block, gradientHL1[x+1][y+1] is the second horizontal gradient block, gradientVL0[x+1][y+1] is the first vertical gradient block, and gradientVL1[x+1][y+1] is the second vertical gradient block.
