Abstract
Provided are a method and apparatus for decoding video signal based on weighted prediction. The method may include determining an inter prediction mode of a current block, deriving motion information of a current block according to the inter prediction mode, obtaining a first prediction block of the current block based on the motion information, and obtaining a second prediction block of the current block by applying at least one of a weight, an offset, or a first variable for explicit weighted prediction to the first prediction block.
