Typos in the Text

Description

In ITU-T H.265 (10/2014) as well as JCTVC-R1013_v6 I found some typos:

In F.7.3.2.3.3:
"if( resample_phase_set_prsent_flag[ i ] ) {" sould be "if( resample_phase_set_present_flag[ i ] ) {"

In F.7.3.2.3.5:
"idxShiftY = idxY + ( ( i << ( cm_octant_depth − inpDepth ) )". There is one too many open brackets "(".

In H.8.1.4.2:
... "where xPb = xB << 4 and xPb = xB << 4, for" ...
I guess the correct version is:
... "where xPb = xB << 4 and yPb = yB << 4, for" ...

Also in H.8.1.4.2:
In steps 4 and 5 the index "xP" and "yP" are used multiple times. However, these indices were not defined in this context. I guess the correct indices are "xPb" and "yPb".

  • Milestone set to v5
  • Version set to v4 (12/2016)
  1. The typo ‘resample_phase_set_prsent_flag’ is fixed in the 2016/12 release of the HEVC specification.
  2. Agreed by the authors of the AHG2 report JCTVC-AD0002. The redundant ‘(‘ in subclause F.7.3.2.3.6 is still present in the 2016/12 release of the HEVC specification.

Fix:
In F.7.3.2.3.6, change

idxShiftY = idxY + ( ( i << ( cm_octant_depth − inpDepth ) )

to

idxShiftY = idxY + ( i << ( cm_octant_depth − inpDepth ) )

  1. The issue regarding xPb/yPb is fixed in the 2016/12 release of the HEVC specification (note: now affected clause is H.8.1.4.3 and the variables were renamed to xP/yP).
  2. xP/yP are now the correct names to use (so no action needed).
