Abstract
A method for decoding a bitstream, including compressed pictures of a video, wherein each picture includes one or more slices, wherein each slice includes one or more blocks of pixels, and each pixel has a value corresponding to a color, for each slice, first obtains a reduced number of colors corresponding to the slice, wherein each color is represented as a color triplet and the reduced number of colors is less than or equal to a number of colors in the slice. Then, for each block, a prediction mode is determined, wherein an independent uniform prediction mode is included in a candidate set of prediction modes. For each block, a predictor block is generated, wherein all values of the predictor block have a uniform value according to a color index when the prediction mode is set as the independent uniform prediction mode. Lastly, the predictor block is added to a reconstructed residue block to form a decoded block as output.
