Intraprediction-encoded video encoding method and video encoding apparatus

The video encoding method of the present invention provides a video encoding apparatus and INTRA. The method comprising: depth N of the current layer coding unit CU traverse prediction to obtain the predicted result of the current layer, CU, wherein traversing the prediction does not include the current layer CU prediction unit predicts the predicted results include traversing Prediction current best CU CU division pattern layers, the current layer is divided CU CU is divided according to the best prediction mode and the current mode sub CU CU desired layer encoded syntax elements; CU if the best mode of the current layer is divided into CU 4 is a depth of the sub-CU N + 1, and the same depth of four sub-CU N + 1 is the prediction mode, the CU is divided according to the best mode, the current is divided according to the best layer CU CU CU division patterns of prediction mode and the current required encoded syntax elements CU layer to the current layer of the current coding unit CU CU layer encoding.
