METHOD AND APPARATUS FOR ENCODING/DECODING VIDEO USING SPLIT LAYER

摘要

The present invention relates to a method and an apparatus for encoding/decoding a video using a split layer. The video encoding/decoding method generates an encoded image data by encoding a current block partitioned into a plurality of subblocks, generates an encoded partition information data by encoding partition information of the current block, generates a bitstream including the encoded image data and the encoded partition information data, and then reconstructs the video image from the generated bitstream. According to the present disclosure, when encoding a high resolution video with variable sized blocks, various block shapes may be used for the encoding, and efficient encoding and decoding of the block partition information can improve the compression efficiency.

1. A method of encoding a video in the unit of blocks, the method comprising:
encoding a first information on a minimum block size and a second information on a difference between a maximum block size and the minimum block size; dividing a square current block having the maximum block size into one or more subblocks which are equal to or larger than the minimum block size by a tree structure, and encoding partition information of the current block divided by the tree structure; encoding a prediction mode of each of the subblocks, the prediction mode indicating whether a subblock is inter-predicted or intra-predicted; and encoding residual signals of each of the subblocks by predicting each of the subblocks according to a corresponding prediction mode.
