Abstract
Disclosed is a method for decoding a video signal, including deriving position information of an integer sample within a target block, performing non-uniform interpolation filtering on the integer sample based on the position information of the integer sample, deriving an interpolation sample value according to a result of the non-uniform interpolation filtering, and obtaining a prediction sample value using the interpolation sample value, wherein the non-uniform interpolation filtering is different in at least one of a phase interval or the number of interpolation samples, the phase interval represents an interval between interpolation samples, and the number of interpolation samples represents the number of interpolation samples generated between integer samples.
