1. A video decoding method, comprising:
acquiring, from a bitstream, block partitioning information of a current block having a tree-based partitioning structure;
performing block partitioning on the current block by using the acquired block partitioning information;
generating a prediction signal of a current sub-block among sub-blocks resulting from the block partitioning on the current block; and
reconstructing the current sub-block based on the prediction signal,
wherein the block partitioning information includes first partitioning information indicating whether or not to partition a block into four sub-blocks, second partitioning information indicating whether or not to partition a block into two sub-blocks, and partitioning direction information indicating whether a direction of the block partitioning into the two sub-blocks is a horizontal direction or a vertical direction,
wherein the second partitioning information and the partitioning direction information is acquired from the bitstream, respectively,
wherein acquiring the block partitioning information comprises:
parsing the first partitioning information from the bitstream;
determining whether additional block partitioning information is parsed from the bitstream; and
parsing the additional block partitioning information from the bitstream, in response to the determination that the additional block partitioning information is parsed,
and
wherein the additional block partitioning information includes at least one of the second partitioning information or the partitioning direction information.
