1. A method for decoding a video signal by a decoding apparatus in intra planar prediction mode, the method comprising:
predicting, by the decoding apparatus, a video data sample included in a current block based on a bi-linear interpolation using a first reference sample, a second reference sample, a third reference sample, and a fourth reference sample, the first reference sample being a left neighboring sample of the current block and having a same y-coordinate as the video data sample, the second reference sample being an upper neighboring sample of the current block and having a same x-coordinate as the video data sample, the third reference sample being a reference sample taken from an upper-right neighboring block of the current block and positioned in the same y-coordinate as the video data sample within a rightmost column of the current block for the bi-linear interpolation, and the fourth reference sample being a reference sample taken from a lower-left neighboring block of the current block and positioned in the same x-coordinate as the video data sample within a bottommost row of the current block for the bi-linear interpolation; and reconstructing, by the decoding apparatus, the video data sample based on the predicted video data sample, wherein, a weighting factor applied for the fourth reference sample is determined based on the y-coordinate of the video data sample. |
