Abstract

The invention provides a block division method applied to video decoding, and the method comprises the steps: obtaining a division mode of a current node, and enabling the division mode to be used fordividing a first component block of the current node; whether the first component block meets a preset condition corresponding to the division mode or not is judged, if the preset condition is met, it is determined that a second component block of the current node is not divided or divided in the division mode of the current node, and the size of the first component block is larger than that of the second component block. The invention provides a block division method, a video decoding method, a video encoding method, a video decoder and a video encoder which are applied to video encoding soas to improve encoding / decoding performance.
