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.

Claims

1. A method for decoding a bitstream comprising:

(a) decoding at least one pictures from the bitstream; 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.

2. The method according to claim 1, wherein

(a) receiving a palette_mode_flag, wherein the palette_mode_flag is equal to 1 specifies a current coding unit is coded using a palette mode.

3. The method according to claim 1, wherein

the palette table predictor size specifies the size of the palette table predictor.
