Assignee: LG ELECTRONICS INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. A transmission method of data for a video, the method comprising:
obtaining a bitstream for the video, wherein the bitstream is generated based on determining that an intra prediction is applied to a current block, constructing a candidate mode list including a plurality of candidate modes for the current block, generating 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 the video information including the index information; and
transmitting the data comprising the bitstream,
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.
