    摘要： Methods and apparatuses for encoding and decoding a video are provided. The method of encoding a video includes generating an extended corresponding block by extending a corresponding block of a reference picture; generating a filtered extended corresponding block by using a predetermined first filter; performing interpolation in sub-pixel units by using a predetermined second filter; and performing motion prediction and compensation by using the reference picture that is interpolated in the sub-pixel units. The method of decoding a video includes extracting information of a current block; generating an extended corresponding block by extending a corresponding block of a reference picture; generating a filtered extended corresponding block by applying a predetermined first filter to the extended corresponding block; performing interpolation in sub-pixel units by applying a predetermined second filter to the filtered extended corresponding block; and performing motion compensation by using the reference picture that is interpolated in the sub-pixel units.
