A method of a digital processor for a low complexity transform unit partitioning structure for High Efficiency Video Coding, comprising:
- determining prediction unit size of a coding unit;
- and
- setting the size of transform unit size of Y, U and V according to the prediction unit size of the coding unit, wherein when a prediction unit and the coding unit are the same size the transform unit for Y is set to NY×NY, NY=TUsize(2N, maxTUsiz, minTUsize) and for U and V to NC×NC, NC=TUsize(N, maxTUsiz, minTUsize);
- otherwise transform unit for Y is set to =NY×NY, NY=TUsize(N, maxTUsiz, minTUsize) and transform unit for U and V are set to NC×NC, NC=TUsize(N, maxTUsiz, minTUsize).
At least one of an encoder or a decoder performing a method, comprising:
- determining prediction unit size of a coding unit;
- and
- setting the size of transform unit size of Y, U and V according to the prediction unit size of the coding unit, wherein when a prediction unit and the coding unit are the same size the transform unit for Y is set to NY×NY, NY=TUsize(2N, maxTUsiz, minTUsize) and for U and V to NC×NC, NC=TUsize(N, maxTUsiz, minTUsize);
- otherwise transform unit for Y is set to=NY×NY, NY=TUsize(N, maxTUsiz, minTUsize) and transform unit for U and V are set to NC×NC, NC=TUsize(N, maxTUsiz, minTUsize).
A non-transitory computer readable medium comprising computer instruction, when executed perform a method for a low complexity transform unit partitioning structure for High Efficiency Video Coding (HEVC), comprising:
