VIDEO CODING DEVICE, VIDEO DECODING DEVICE, VIDEO CODING METHOD, AND VIDEO DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/064700
Kind Code:
A1
Abstract:
In the present invention, a video coding device 10 applies prediction and conversion to coding units (CUs) segmented in a quadtree or a multi-type tree, wherein the video coding device includes a control unit 11 for controlling the positions where a screen in a video is segmented such that the vertical-position value of individual segment boundaries on the screen is a multiple of the maximum coding tree unit (CTU) size that is utilized.
