Abstract

A video decoding method includes: receiving an encoded video bitstream, and decoding a first block. The encoded video bitstream includes data to be decoded as the first block of pixels in a picture, and the first block includes a luma block and at least one chroma block. Decoding the first block includes: determining whether to apply a neural network (NN) filter on the luma block and the at least one chroma block according to an NN filter mode of the luma block and at least one NN filter mode of the at least one chroma block.
