Abstract:
1. 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).
