摘要： The present invention is related to processing a video signal. A method for decoding a video according to the present invention may comprise generating a prediction block of a current block by performing intra prediction, deriving at least one sample position based parameter based on a position of a first prediction sample in the prediction block, and obtaining a second prediction sample by weighted predicting the first prediction sample based on the at least one sample position based parameter. According to the present invention, encoding/decoding efficiency of a video signal can be improved since intra prediction is performed more accurately.
