Abstract
In one aspect there is disclosed a method of applying deblocking on implicit vertical TU boundaries when the CU width is larger than the maximum TU width and applying deblocking on implicit horizontal TU boundaries when the CU height is larger than the maximum TU height. Some exemplary embodiments include HEVC deblocking and deblocking using longer filters.
Claims1
A method for decoding a coded video picture, the method comprising:
- obtaining a block B of the coded video picture, wherein the block B is of size D1×D2;
- determining that D1 is greater than a predetermined maximum transform size (N);
- after determining that D1 is greater than N, splitting the block B into at least a first sub-block B1 and a second sub-block B2, wherein the sub-block B1 is of size N×D2 or N×N, and wherein the sub-block B2 is of size N×D2 or N×N, and further wherein at least one of the sub-blocks B1 or B2 contains transform coefficients;
- and
- applying a deblocking filter to a boundary between the first sub-block B1 and the second sub-block B2, wherein the deblocking filter modifies one or more samples on a first side of the boundary and one or more samples on a second side of the boundary.
