Claim:
1. A video decoding method, comprising: reconstructing a syntax corresponding to at least one of a first block, a second block and a third block wherein: reconstructing 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 and a vertical prediction value, 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 of 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 low-left pixel outside of the prediction block, and wherein the upper-right pixel outside of the prediction block is shared for calculating the horizontal prediction value of each prediction pixel in the prediction block, and the lower-left pixel outside of the prediction block is shared for calculating the vertical prediction value of each prediction pixel in the prediction block.
