Claim Text:
1. A video decoding apparatus, comprising: a decoder configured to reconstruct a syntax corresponding to at least one of a first block, a second block and a third block, wherein a predictor configured to reconstruct a prediction block corresponding to at least one of the first block, the second block and the third block, wherein a prediction pixel in the prediction block is generated by averaging a horizontal prediction value of the prediction pixel and a vertical prediction value of the prediction pixel, wherein the horizontal prediction value is calculated by using a pixel adjacent to the left side of the prediction block and an upper-right pixel outside the prediction block, and the vertical prediction value is calculated by using a pixel adjacent to the upper side of the prediction block and a lower-left pixel outside the prediction block, and wherein the upper-right pixel outside the prediction block is commonly used to calculate the horizontal prediction value of each prediction pixel in the prediction block, and the lower-left pixel outside the prediction block is commonly used to calculate the vertical prediction value of each prediction pixel in the prediction block.
