ADVANCED SCREEN CONTENT CODING WITH IMPROVED PALETTE TABLE AND INDEX MAP CODING METHODS

摘要

An apparatus is configured to perform a method for screen content coding. The method includes deriving a color index map based on a current coding unit (CU). The method also includes encoding the color index map, wherein at least a portion of the color index map is encoded using a first coding technique, wherein a first indicator indicates a significant distance of the first coding technique. The method further includes combining the encoded color index map and the first indicator for transmission to a receiver.
