Abstract
An encoding method includes: determining a mode parameter of a chroma component of a current block; in a case where the mode parameter satisfies a first condition, determining a first transform kernel of the chroma component of the current block; and determining transform coefficients of the chroma component of the current block, and performing inverse transform on the transform coefficients of the chroma component of the current block according to the first transform kernel to determine a residual block of the chroma component of the current block.
