1. A method implemented by a processor, comprising:
obtaining a reference picture from a reference picture list of a current processing unit based on a parameter of the reference picture, wherein the parameter comprises a number of merge with motion vector difference (MMVD) blocks of the reference picture, and wherein the MMVD blocks are coded by an MMVD mode in the reference picture; and
obtaining a distance table of the MMVD mode for the current processing unit based on the reference picture.
