Method and apparatus for predicting and restoring a video signal using palette entry and palette mode

Abstract:

Provided is a method for decoding a video signal. Such a method may include constructing a palette map related to a current block encoded in a palette mode, determining, based on a mode identifier of a current sample included in the current block, a palette index mode of the current sample, the mode identifier is used to determine one of an index mode or a copy mode, deriving a palette index of the current sample based on the palette index mode, and reconstructing the current sample by using the palette map of the current block and the palette index.
