1. A video decoding method comprising:
decoding adaptive loop filter information of a coding tree block; and
applying an adaptive loop filter on the coding tree block based on the adaptive loop filter information,
wherein, for a luma component of the coding tree block, the adaptive loop filter is applied by using a 7×7 rhombus filter, and
wherein, for a chroma component of the coding tree block, the adaptive loop filter is applied by using a 5×5 rhombus filter.
