METHOD AND DEVICE FOR VIDEO ENCODING/DECODING AND METHOD FOR TRANSMITTING BIT STREAM Russian patent published in 2024 - IPC H04N19/117 H04N19/593 H04N19/82 

FIELD: image coding.

SUBSTANCE: image encoding/decoding by performing intra prediction using reference sample filtering and a method for transmitting a bit stream. A method includes: obtaining intra-prediction mode information of the current block from a bit stream, determining the intra-prediction mode of the current block based on the information of the intra-prediction mode and the intra-prediction mode of the neighboring block located near the current block, extracting the value of the first filter flag for use filtering the intra-prediction reference sample of the current block based on encoding parameters for the current block, selecting an interpolation filter to be used for intra-prediction of the current block based on the first filter flag, and generating an intra-prediction block of the current block using the selected interpolation filter.

EFFECT: increased efficiency of encoding/decoding.
