Abstract
The present disclosure provides a video encoding apparatus and encoding method thereof, video decoding apparatus and decoding method thereof, and directional intra-prediction method to be used therefor. The video encoding apparatus includes a main mode search unit for searching for main mode for a current block from among directional intra-prediction modes; a sub mode search unit for searching for sub modes formed by inclining indicated orientation of found main mode by main mode search unit by a predetermined offset in both clockwise and counterclockwise directions; a predicted block generator for generating predicted block of the current block from neighboring blocks of the current block based on found main mode by the main mode search unit and found sub modes by the sub mode search unit; a differentiator for calculating differential between the current block and the predicted block; and an encoder for encoding calculated differential by the differentiator.
