1. A method of coding implemented by an encoding/decoding device, the method comprising:
obtaining a parent block of a current coding block (denoted as parentCurr) and a parent block of a candidate coding block (denoted as parentCand);
obtaining the current coding block by splitting of the parentCurr; and
obtaining the candidate coding block by splitting of the parentCand, wherein the current coding block cannot use an intra prediction mode of a potential candidate coding block, when:
the parentCand and the parentCurr are the same block,
a function of a number of quadtree, ternary tree, and binary tree splitting operations that are performed to obtain the candidate coding block is greater than a threshold minus 1, and
a split mode of the parentCurr is a ternary tree split.
