Abstract

An image decoding method according to the present invention may comprise the steps of: generating a first prediction block for the current block on the basis of a first prediction mode; generating a second prediction block for the current block on the basis of a second prediction mode; and generating a final prediction block for the current block on the basis of the first and second prediction blocks.

Description

technical field [0001] The present invention relates to methods and apparatus for processing video signals. Background technique [0002] Recently, demands for high-resolution and high-quality images such as high-definition (HD) images and ultra-high-definition (UHD) images have increased in various application fields. However, the data amount of image data with higher resolution and higher quality increases compared to conventional image data. Therefore, when image data is transmitted by using a medium such as conventional wired and wireless broadband networks or when image data is stored by using a conventional storage medium, the cost of transmission and storage increases. In order to solve these problems that arise as the resolution and quality of image data increase, efficient image encoding / decoding techniques can be utilized. [0003] Image compression techniques include various techniques including: an inter-frame prediction technique for predicting pixel values ​​...
