Abstract:
Provided is a video decoding method including obtaining, from a bitstream, information about a prediction mode of a current block; when the prediction mode of the current block is an intra mode, obtaining information about an intra prediction mode of the current block; obtaining a predicted sample value of the current block by using at least one sample that is from among samples included in an adjacent reference region of a plurality of lines and is located, from the current block, in an intra prediction direction indicated by an intra prediction mode. The adjacent reference region of the plurality of lines may include a plurality of lines that are in a vertical direction and located at a left side of the current block, or a plurality of lines that are in a horizontal direction and located at an upper side of the current block.

Claim (Index 9):
The video decoding method of  claim 1 , wherein, when the intra prediction direction is a specific direction based on a specific-angle directional mode, and when an angle in the specific direction from the horizontal direction is greater than an angle in a 45-degree direction from the horizontal direction and is less than an angle in a vertical direction,\n the obtaining of the predicted sample value of the current block comprises: performing filtering on a plurality of first adjacent samples located in the specific direction from a first adjacent sample adjacent to an extension line extending in the horizontal direction from an upper corner of the current block; and obtaining the predicted sample value of the current block according to the specific direction by using the plurality of filtered first adjacent samples.
