Decoding methods and equipment

Abstract

The invention relates to a decoding method in which the encoded information of a block is received from an encoded vector bit stream. The encoded information indicates that the block is partitioned based on a geometric partition modulus (GPM) of first and second components and is externally predicted based on a merge mode with motion vector difference (MMVD). The motion vector for the first part of the block, partitioned by GPM, is not identical to the motion vector for the second part of the block, partitioned by GPM. The block is then reconstructed based on the motion vector for the first part and the motion vector for the second part.
