Method and apparatus for encoding/decoding image using variable-size macroblocks
A video decoding apparatus using a tree structure, includes: a decoder to decode, from a bitstream, a partition flag indicating whether each block, starting from a block corresponding to an uppermost layer of the tree structure, is divided into four blocks of a lower layer, and thereby identify a block which is not further divided, and decode prediction type information on the identified block from the bitstream; and a reconstructor to reconstruct the identified block by using a prediction mode indicated by the prediction type information, wherein, when a block of a first layer is divided into four blocks of a second layer which is a lower layer of the first layer, the decoder is configured to decode the partition flag for each of the four blocks of the second layer in a predetermined order.
