Abstract

One embodiment of the present invention relates to a method and an apparatus for encoding/decoding video using a high-precision filter. One embodiment of the present invention provides a method and an apparatus for encoding/decoding video, and in the method for encoding/decoding video, the value of a subsample element of a reference block, which is referenced by the motion vector of a current block, is encoded and decoded by generating a predictive block from a value that is interpolated using an FIR filter and linear interpolation, so as to more accurately interpolate the current block, thereby increasing encoding efficiency by reducing the difference between the actual block and the predictive block, and thus improving compression efficiency.
