Description

The range of PaletteEscapeVal never exceeds (1 << Bitdepth)- 1 as the minimum Qp for the escape values is 4 in the current spec. Therefore, the following sentence should be changed from :

It is a requirement of bitstream conformance that PaletteEscapeVal[ cIdx ][ xC ][ yC ] shall be in the range of 0 to (1 << ( BitDepth + 1 ) ) − 1, inclusive, for cIdx equal to 0, and in the range of 0 to (1 << ( BitDepth + 1 ) ) − 1, inclusive, for cIdx not equal to 0.

to :

It is a requirement of bitstream conformance that PaletteEscapeVal[ cIdx ][ xC ][ yC ] shall be in the range of 0 to ( 1 << BitDepth ) − 1, inclusive, for cIdx equal to 0, and in the range of 0 to (1 << BitDepth ) − 1, inclusive, for cIdx not equal to 0.
