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

Abstract:

Provided is a method for decoding a video signal. Such a method may include constructing a palette map for a current block encoded in a plate mode, the palette map comprises at least one palette entry and a map index that for identifying the palette entry, deriving a palette index according to a predetermined scan order of the current block on a sample-by-sample basis, and reconstructing each sample of the current block by using a palette entry having a map index of the same value as the derived palette index from the palette map.
