Abstract
A video signal processing method according to the present invention is characterized by obtaining at least one palette entry of a current block from a palette map of a previous block, constructing a palette map of a current block including the obtained palette entry, deriving a palette index in a unit of a sample of a current block, and reconstructing a current block by using a palette map of a current block and a palette index.
Claims15
A method of decoding a video signal, the method comprising:
- obtaining at least one palette entry of a current block from a palette map of a previous block;
- constructing a palette map of the current block including the obtained palette entry;
- deriving a palette index in a unit of a sample of the current block;
- and
- reconstructing the current block 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 obtaining at least one palette entry of a current block from a palette map of a previous block, constructing a palette map of the current block including the obtained palette entry, deriving palette index in a unit of a sample of the current block, and reconstructing the current block by using a palette map of the current block and the palette index.
