摘要

1. A video decoding method, comprising the steps of: receiving a bitstream regarding an encoded video; obtaining a minimum size information indicating a minimum size of an encoding block from a bit stream; encoding blocks obtained by hierarchical partitioning from a maximum encoding block are determined using partition information of said coding block syntactically analyzed from a bitstream; at least one prediction block is obtained from said coding block with edi coding blocks using a coding section The block type syntax parsed from the bitstream; and performing intra-frame prediction with respect to said at least one prediction block, wherein: when the size of said coding block is equal to a minimum size of a coding block, the section type indicates one of a first type for a prediction block having the same size as said coding block, a second type for prediction blocks obtained by dividing the heights of said coding block, a third type for prediction blocks obtained by dividing the widths of said block encoding, and a fourth type of prediction blocks obtained by dividing the heights and widths of said coding block, when the size of said coding block is larger than the minimum size of the coding block, the partition type indicates one of the first type, the second type and the third type. 2. The method of claim 1, further comprising the steps of obtaining depth information from the bitstream indicating changes
