Abstract: Embodiments of the present invention provide a video coding method for INTRA and a video coding apparatus. The method includes performing a traversal prediction on a current-layer coding unit CU, a prediction mode of a sub-Cu that is divided, from the current-layer CU, and a syntax element that is needed for coding of the current-layer CU; and if the best CU division mode is to divide the current-layer CU into four sub-CUs whose depth is N+1, and prediction modes of the four sub-CUs whose depth is N+1 are the same, performing coding, by using the current-layer CU as a coding unit, on the current-layer CU according to the best CU division mode, the prediction mode of the sub-CU that is divided from the current-layer CU according to the best CU division mode, and the syntax element that is needed for coding of the current-layer CU.
