DEVICE AND METHOD FOR TRANSMITTING BIT STREAM Russian patent published in 2024 - IPC H04N19/82 

FIELD: video encoding.

SUBSTANCE: result is achieved by the fact that the device for transmitting a bit stream includes a circuit and a storage 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 codes the third reconstructed image sample of the colour signal component using the clipped third coefficient value and transmits a bit stream including the encoded third reconstructed image sample.

EFFECT: high efficiency of video encoding.
