TWO-DEMENSIONAL PALETTE CODING FOR SCREEN CONTENT CODING

摘要

Video data, e.g., screen content video data may be palette coded. A palette table including one or more color indices may be produced. A color index may correspond to one color. A palette index map may be created that maps one or more pixels of the video data to a color index in the palette table, or a color that may be explicitly coded. A palette index map prediction data may be generated that includes data that indicates values in the palette index map associated with at least some portions of the video data that are generated in a traverse scan order in which a scan line is scanned in an opposite direction of a preceding parallel scan line.
