Abstract
The invention is: A method for decoding a bitstream comprising: (a) decoding at least one pictures from the bit-stream; and (b) partitioning each of the at least one pictures into a plurality of slices, wherein each of the plurality of slices includes at least one coding units, wherein (c) palette table predictor size of a coding unit of the at least one coding units is set equal to 0 at start of a slice of the plurality of slices.
Claims1
A method for decoding a bitstream comprising:
- (a) receiving the bitstream including at least one picture which includes a plurality of titles, wherein each of the plurality of tiles comprises a plurality of coding units;
- (b) receiving a new palette entry in the bistream;
- (c) generating a palette table predictor by using a previous palette table which includes a set of pixel values of a previous coding unit;
- (d) generating a current palette table by using the palette table predictor and the new palette entry;
- and
- (e) decoding pixel values of a current coding unit by using the current palette table, wherein
- a size of the palette table predictor, specifying a number of entries of the palette table predictor, being set equal to 0 at start of each of the plurality of tiles, and
- the palette table predictor is not used for generating the current palette table when the size of the palette table predictor is equal to 0.
