Abstract

The present invention discloses a method and an apparatus for encoding and decoding video. A video decoding method comprises reconstructing a residual value by entropy-decoding received bitstream and dequantizing and inverse-transforming residual value information, generating a final prediction unit by performing inter prediction on a prediction unit which is partitioned from a coding unit into at least two prediction units by asymmetric motion partitioning (AMP), the two partitioned prediction units comprising a first partitioned prediction unit and a second partitioned prediction unit, and reconstructing a picture by adding the final prediction unit to the residual values.

Description

[0001] This patent application is a divisional application of a patent application with an international filing date of November 2, 2012, a national application number of 201280066253.8, and an invention title of "Image Coding Method and Device and Image Decoding Method and Device". technical field [0002] The present invention relates to image processing, and more particularly, to an inter prediction method and device, and a method of decoding a video signal having a current block to be decoded. Background technique [0003] Recently, demands for high-resolution and high-quality videos such as high-definition (HD, high-definition) and ultra-high-definition (UHD, ultrahigh-definition) videos have increased. [0004] In order to provide video with higher resolution and higher quality, the amount of video data increases. Therefore, the cost of transferring and storing video data rises in order to provide high-quality video compared to conventional video data processing method...
