FIELD: computer technology for decoding video data.
SUBSTANCE: intra-prediction mode is one of the directional intra-prediction modes with a prediction angle greater than 0, whereas based on the size of the current block, which is greater than or equal to the first specific value, the interpolation filter for the target sample is output as a Gaussian filter, and based on the current block size being smaller than the first specific value and the prediction angle of the intra-prediction mode being smaller than the second specific value, the interpolation filter for the target sample is output as a cube filter, and whereas, based on the current block size being smaller than the first specific value and the prediction angle of the intra-prediction mode being not smaller than the second specific value, the interpolation filter for the target sample is output as a Gaussian filter.
EFFECT: increase in efficiency of video decoding.
