An apparatus and method for screen content encoding includes deriving a palette table and a color index map based on a coding unit (CU). The method also includes encoding the palette table and encoding the color index map. The method further includes combining the encoded palette table and the encoded color index map for transmission to a receiver, where the palette table and index map are decoded to reconstruct a pixel block.

Advanced screen content coding with improved color table and index map coding methods

A method and device for coding screen content into a bitstream by selecting a color palette table for a coding unit (CU) of screen content, creating a color index map having indices for the coding unit (CU), and encoding the selected color palette table and the color index map for the CU into a bitstream.
