Abstract

Provided are a method and apparatus for encoding/decoding video. The method and apparatus of the present invention involve generating a first prediction block for a block to be decoded, calculating a filter coefficient on the basis of the block adjacent to the first prediction block, and performing filtering on the first prediction block using the filter coefficient so as to generate a second prediction block if information relating to the performance of filtering indicates that filtering should be performed. According to the present invention, accuracy in video prediction and encoding performance are improved.
