Method and apparatus for processing video signal

A method of decoding a video, the method comprising:

• determining a prediction mode of a current block, the prediction mode being determined as one of intra prediction and inter prediction;
• obtaining a first prediction sample of the current block by performing the intra prediction or the inter prediction for the current block according to the prediction mode;
• and
• obtaining a second prediction sample of the current block based on the first prediction sample,
• wherein reference samples of the current block are derived based on reconstructed samples adjacent to the current block,
• wherein the second prediction sample is obtained by applying a first weight to the first prediction sample and applying a second weight to a value derived by at least one of the reference samples, and
• wherein the first weight and the second weight are determined based on which one of the intra prediction and the inter prediction is applied to a neighboring block adjacent to the current block.

A method of encoding a video, the method comprising:

• encoding information on a prediction mode of a current block, the prediction mode representing one of intra prediction and inter prediction;
