Abstract
(EN)
A method for decoding a video according to the present disclosure may comprise: a step for configuring a current palette table on the basis of a previous palette table; a step for determining a palette index in units of pixels in the current block; and a step for restoring the pixels in the current block on the basis of the palette table and the palette index.
