Description

(1) On page 160 of JVET-O2001-vE.docx, under 7.4.9.6, Palette coding semantics, after the paragraph of copy_above_palette_indices_flag, there are two conflicting sentences:

The value of PaletteIndexMap[ xC ][ yC ] shall be in the range of 0 to ( MaxPaletteIndex – 1), inclusive.

The value of PaletteIndexMap[ xC ][ yC ] shall be in the range of 0 to MaxPaletteIndex, inclusive

One of them should be removed.

(2) Variable palette_max_size and PaletteMaxPredictorSize are referred in the draft text, but they are never defined or signaled. In VTM6 software, they are defined as 31 (MAXPLTSIZE) and 63 (MAXPLTPREDSIZE).
