  • Publication number: 20190273919
    Abstract: The present invention relates to efficient signaling of an intra prediction mode for predicting a current block in intra prediction coding. According to an aspect of the present invention, a video encoding apparatus divides dozens of intra modes into groups, selects a group to which an actual intra mode of the current block to be encoded belongs, and signals a value corresponding to the group. The video decoding apparatus acquires information on the group to which the actual intra mode of the current block belongs from a bit-stream and then evaluates intra modes belonging to the group to select a final intra mode.

  • Publication number: 20190260990
    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.
