Typos in JVET-O2001

[Tomohiro Ikai]

In the latest JVET-O2001-vB, the followings would be typos.

1. In 7.3.4.1 General HRD parameters syntax ¶

HDR would be HRD.

7.3.4.1	General HDR parameters syntax
would be
7.3.4.1	General HRD parameters syntax

2. In 7.3.8.2 and others ¶

MODE_ALL would be MODE_TYPE_ALL

3. In 7.4.9.7 Merge data semantics ¶

"merge_subblock_flag[ x0 ][ y0 ] is equal to 0." is duplicated, please remove one of them.

When ciip_flag[ x0 ][ y0 ] is not present, it is inferred as follows:
–	If all the following conditions are true, ciip_flag[ x0 ][ y0 ] is inferred to be equal to 1:
–	sps_ciip_enabled_flag is equal to 1.
–	general_merge_flag[ x0 ][ y0 ] is equal to 1.
–	merge_subblock_flag[ x0 ][ y0 ] is equal to 0.
–	regular_merge_flag[ x0 ][ y0 ] is equal to 0.
–	merge_subblock_flag[ x0 ][ y0 ] is equal to 0. **here**

4. In 8.5.2.7 Derivation process for merge motion vector difference ¶

mMvdL10 would be mMvdL1

mMvdL10[ 0 ] = Sign( currPocDiffL0 )  = =  Sign( currPocDiffL1 )  ?	
	mMvdL1[ 0 ]  :  −mMvdL1[ 0 ]	(8 372)

would be

mMvdL1[ 0 ] = Sign( currPocDiffL0 )  = =  Sign( currPocDiffL1 )  ?	
	mMvdL1[ 0 ]  :  −mMvdL1[ 0 ]	(8 372)

5. In 8.6.3 Decoding process for IBC blocks ¶

xVb would be yVb and % would be &

xVb = ( y + bv[ 1 ] >> 4 ) ) % ( CtbSizeY − 1 )		(8 874)

would be

yVb = ( y + bv[ 1 ] >> 4 ) ) & ( CtbSizeY − 1 )		(8 874)

6. In 8.7.4.2 Low frequency non-separable transformation process ¶

There're duplicated "of" after "a list".

–	a list of of scaled non-zero transform coefficients x[ j ] with j = 0..nonZeroSize − 1,

7. In 6.5.2 Up-right diagonal and raster scan order array initialization process ¶

Here I'm not so sure, but rasterScan's parameter (x, y) is swapped, isn't it?

			rasterScan[ x * blkWidth + y] = i
could be
			rasterScan[ y * blkWidth + x] = i

Plus, the rasterScan's naming can be confusing since this is not a usual rasterScan but rasterScan2DiagonalScanPos or something.
The variable is used as RasterScanOrder[] for scaling list.

I would like to report some other typos.

7.4.3.1 Decoding parameter set RBSP semantics
In (7-7), missing ']' at the end of line (bold text)

if ( i = = 0)

SubPicTop[ subpic_grid_idx[ i ][ j ] ] = 0

else if( subpic_grid_idx[ i ][ j ] != subpic_grid_idx[ i – 1 ][ j ] )
{

SubPicTop[ subpic_grid_idx[ i ][ j ] ] = i
SubPicHeight[ subpic_grid_idx[ i − 1][ j ] ] = i − SubPicTop[ subpic_grid_idx[ i − 1 ][ j ]

}

8.5.2.1 equation (8-268)

hpelIfIdx = AmvrShift = = 3 : 1: 0

whould be

hpelIfIdx = AmvrShift = = 3 ? 1: 0
