Claim 3:
4. The apparatus of claim 3, wherein the one or more extension offsets comprise a first offset set, a second offset, a third offset and a fourth offset, and wherein the location of the first extension block is determined by the following:

(Xe0,Ye0)=(Xi0−offset1,Yi0−offset2),

(Xe1,Ye1)=(Xi1+offset3,Yi1−offset2),

(Xe2,Ye2)=(Xi2−offset1,Yi2+offset4),

(Xe3,Ye3)=(Xi3+offset3,Yi3+offset4),

wherein (Xe0, Ye0) is a coordinate of an up-left corner of the first extension block, (Xe1, Ye1) is a coordinate of an up-right corner of the first extension block, (Xe2, Ye2) is a coordinate of a bottom-left corner of the first extension block, (Xe3, Ye3) is a coordinate of a bottom-right corner of the first extension block, (Xi0, Yi0) is a coordinate of an up-left corner of the first prediction block, (Xi1, Yi1) is a coordinate of an up-right corner of the first prediction block, (Xi2, Yi2) is a coordinate of a bottom-left corner of the first prediction block, (Xi3, Yi3) is a coordinate of a bottom-right corner of the first prediction block, and offset1, offset2, offset3 and offset4 belong to the one or more extension offsets, and are non-negative values.
