VIDEO CODING AND DECODING METHOD AND APPARATUS

摘要

A video decoding apparatus includes: a decoder to reconstruct a syntax corresponding to at least one of a first block, a second block and a third block, the first block being generated by dividing a frame for decoding, the second block corresponding to a unit of a prediction and is generated by dividing the first block, and the third block corresponding to a unit of transformation and is generated by dividing the first block in a tree structure; and a predictor to reconstruct a prediction block corresponding to at least one of the first block, the second block and the third block.
