Claim 12:
13. A device for use in a decoder, the device comprises:
a memory, configured to store executable intra prediction instructions; and
a processor, configured to execute the executable intra prediction instructions stored in the memory to perform operations comprising:
determining occupation information of a first number of neighbouring nodes of a current node by enabling intra prediction;
determining occupation information of a second number of neighbouring nodes of the current node according to a position relationship between at least one neighbouring node of the current node and a child node of the current node, the first number being greater than the second number, wherein the position relationship comprises that the at least one neighbouring node of the current node adjoins the child node of the current node by a face, edge or corner; and
determining an occupation prediction result of the child node of the current node based on the occupation information of the first number of neighbouring nodes of the current node and the occupation information of the second number of neighbouring nodes.
