  • Publication number: 20210092367
    Abstract: Disclosed herein is a method of encoding prediction information about a current block located in a first face to be encoded in encoding each face of a 2D image onto which 360 video is projected. The method includes generating prediction information candidates using neighboring blocks around the current block; and encoding a syntax element for the prediction information about the current block using the prediction information candidates. When a border of the current block coincides with a border of the first face, a block adjoining the current block based on the 360 video rather than the 2D image is set as at least a part of the neighboring blocks.
