VIDEO ENCODING SYSTEM AND METHOD Russian patent published in 2024 - IPC H04N19/82 

FIELD: physics.

SUBSTANCE: invention relates to video encoding. Result is achieved by the fact that the encoder includes a circuit and a memory device connected to the circuit. Circuit, during operation, generates a first coefficient value by applying a CCALF (cross-component adaptive loop filtering) process to a first reconstructed sample of images of a luminance signal component, generates a second coefficient value by applying an ALF (adaptive loop filtering) process to a second recovered chroma component image sample and cuts off the second coefficient value. Circuit generates the third coefficient value by summation of the first coefficient value with the clipped second coefficient value and cuts off the third coefficient value. Circuit encodes the third reconstructed sample of the chroma component images using the clipped third coefficient value.

EFFECT: high coding efficiency.
