APPARATUS AND METHOD FOR DETERMINING DCT SIZE BASED ON TRANSFORM DEPTH |
| 摘要 |
An apparatus and method for determining a discrete cosine transform (DCT) size based on a transform depth are disclosed herein. The apparatus for determining a DCT size based on a transform depth includes a prediction mode determination unit, a transform unit (TU) generation unit, and a DCT performance unit. The prediction mode determination unit determines a prediction mode in order to determine a DCT size at the root location of a coding unit (CU) present in a coding tree unit (CTU). The transform unit (TU) generation unit partitions the CU into transform units (TUs) based on a residual quad tree (RQT). The DCT performance unit performs a DCT based on the TUs. |
