Claim 5:
6. A video encoding method, comprising:
encoding quad-partitioning information of a block;
encoding non-quad-partitioning information of the block in case the block is not divided into four partitions;
dividing, based on the non-quad-partitioning information, the block into a plurality of partitions;
generating a prediction partition of a current partition among the plurality of partitions by performing prediction for the current partition; and
reconstructing the current partition based on the prediction partition,
wherein the non-quad-partitioning information includes partitioning direction information indicating whether a partitioning direction of the non-quad-partitioning for the block is a vertical direction or a horizontal direction and partitioning number information indicating whether the non-quad-partitioning for the block is a bi-partitioning or a tri-partitioning,
wherein the bi-partitioning is a partitioning type of dividing the block into two partitions of a same size and partitioning depth and the tri-partitioning is a partitioning type of dividing the block into three partitions of a same partitioning depth,
wherein a center partition of the three partitions has a size equal to a sum of a size of the other two of the three partitions, and the other two of the three partitions have a same size,
wherein the partitioning number information is acquired after acquiring the partitioning direction information, and
wherein the partitioning direction information and the partitioning number information are both 1 bit flags, respectively.
