1. A video encoding method, comprising:
determining, by an encoding apparatus, that an intra prediction is applied to a current block;
constructing, by the encoding apparatus, a candidate mode list including a plurality of candidate modes for the current block;
generating, by the encoding apparatus, index information related to one of the plurality of candidate modes of the candidate mode list as an intra prediction mode of the current block; and
encoding, by the encoding apparatus, video information including the index information,
wherein the constructing the candidate mode list includes:
setting a first ordered candidate mode and a second ordered candidate mode, among the plurality of candidate modes of the candidate mode list, based on a first block adjacent to a left side of the current block and a second block adjacent to an upper side of the current block,
wherein the first ordered candidate mode is set equal to a planar mode and the second ordered candidate mode is set equal to a DC mode based on both of the first block and the second block being not available, and
wherein the firstly ordered candidate mode is set equal to the first intra mode and the secondly ordered candidate mode is set equal to the second intra mode based on the first intra mode being different from the second intra mode.
