Abstract
A video signal processing method according to the present invention is characterized by constructing a palette map related to a current block encoded in a palette mode, determining, based on a mode identifies of a current sample included in the current block, a palette index mode of the current sample, deriving a palette index of the current sample based on the palette index mode, reconstructing the current sample by using a palette map of the current block and the palette index.
Claims15
A method of decoding a video signal, the method comprising:
- constructing a palette map related to a current block encoded in a palette mode;
- determining, based on a mode identifies of a current sample included in the current block, a palette index mode of the current sample;
- the mode identifier specifying 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 a palette map of the current block and the palette index.
An apparatus for decoding a video signal, the apparatus comprising:
- a prediction unit for constructing a palette map related to a current block encoded in a palette mode, determining, based on a mode identifies of a current sample included in the current block, a palette index mode of the current sample, deriving a palette index of the current sample based on the palette index mode, and reconstructing the current sample by using a palette map of the current block and the palette index,
- wherein the mode identifier specifies one of an index mode or a copy mode.
