1. A video decoding method, comprising:
configuring a list for a target block using prediction information of a plurality of reference blocks comprising a first reference block and a second reference block which are determined using a position of the target block; and
determining prediction information of a plurality of sub-blocks in the target block using a plurality of candidates in the list configured for the target block,
wherein the plurality of candidates in the list configured for the target block comprise a first candidate and a second candidate,
wherein prediction information of the first candidate is derived from prediction information of the first reference block which is adjacent to the target block,
wherein prediction information of the second candidate is derived from prediction information of the second reference block which is adjacent to the target block,
wherein the plurality of sub-blocks comprise a first sub-block, a second sub-block, a third sub-block and a fourth sub-block,
wherein the prediction information of the first candidate in the list is used as prediction information of the first sub-block,
wherein prediction information of the second sub-block is determined based on the list,
wherein prediction information of the third sub-block is determined based on the list, and
wherein the prediction information of the second candidate in the list is used as prediction information of the fourth sub-block.
