Abstract

A method for processing a video signal according to the present invention comprises: acquiring at least one palette entry for a current block from a palette map for a previous block; configuring a palette map for the current block comprising the palette entry; inducing a palette index for the current block using at least one of palette index information and palette index run for the current block; and restoring the current block using the palette map and the palette index for the current block.

Description

technical field [0001] The present invention relates to methods and devices for processing video signals. Background technique [0002] Recently, demands for high-resolution, high-quality images such as high-definition (HD) images and ultra-high-definition (UHD) images have increased in various application fields. Since video data has higher resolution and higher quality, video data is larger in volume than conventional video data. Therefore, if video data is transferred through existing media such as wired / wireless broadband circuits or stored in existing storage media, transfer costs and storage costs increase. To avoid these problems encountered with higher resolution, higher quality video data, efficient video compression techniques can be used. [0003] Various video compression techniques exist, including: inter-picture prediction in which pixel values ​​included in a current picture are predicted from pictures before or after the current picture; pixel values ​​incl...
