VIDEO ENCODING SYSTEM AND METHOD Russian patent published in 2025 - IPC H04N19/117 H04N19/82 H04N19/186 

FIELD: data processing.

SUBSTANCE: invention relates to video and image encoding/decoding, particularly for cross-component adaptive loop filtering (CCALF). Circuit, in response to the first reconstructed sample of images located outside the virtual boundary, duplicates the reconstructed sample located inside and next to the virtual boundary so as to form a first reconstructed sample of images. Circuitry generates a first coefficient value by applying a CCALF process to the first reconstructed sample of luminance component images. Circuit generates a second coefficient value by applying an adaptive loop filtering (ALF) process to a second reconstructed sample of chroma component images. Circuit generates a third coefficient value by summing the first coefficient value with a second coefficient value and encodes a third restored sample of chroma component images using the third coefficient value.

EFFECT: high efficiency of encoding/decoding.
