Besides editorial bugs, all the four equations are not complete by missing one value for each array not covered. Suggested changes are as follows.

1. In the following sentence, replace "num_tile_columns_minus1" with "num_tile_columns_minus1 + 1":

"The vector columnWidth[ ], specifying the width for every of the num_tile_columns_minus1 columns in units of treeblocks, is derived as follows."

2. In the equation for derivation of columnWidth[] (BTW, the equation number is incorrect, therefore citing the equation number does not work - same for many other equations), replace "for( i = 0; i < num_tile_columns_minus1; i++ )" with "for( i = 0; i <= num_tile_columns_minus1; i++ )".

3. In the following sentence, replace "num_tile_rows_minus1" with "num_tile_rows_minus1 + 1"

"The vector rowHeight[ ], specifying the height for every of the num_tile_rows_minus1 rows in units of treeblocks, is derived as follows."

4. In the equation for derivation of rowHeight[], replace "for( i = 0; i < num_tile_rows_minus1; i++ )" with "for( i = 0; i <= num_tile_rows_minus1; i++ )".

5. Replace the equation for derivation of colBd[] with the following:

colBd[0] = 0 for( i = 0; i <= num_tile_columns_minus1; i++ )

colBd[i+1] = colBd[i] + columnWidth[i]

6. Replace the equation for derivation of rowBd[] with the following:

rowBd[0] = 0 for( i = 0; i <= num_tile_rows_minus1; i++ )

rowBd[i+1] = rowBd[i] + rowHeight[i]

Context: Page 60, section 7.4.3 'Slice Header semantics'

The description of 'num_ref_idx_l0_active_minus1' still has wording that's taken from H.264, including (shudder) MBAFF. There are no field, frame or any other kind of macroblocks.

I believe that all the text starting with 'The range of num_ref_idx_l0_active_minus1 is specified as ..' should be replaced with:

The range of num_ref_idx_l0_active_minus1 shall be in the range of 0 to 15, inclusive.

Context: page 56, section 7.4.2.2 'Picture Parameter set semantics'

Description for num_ref_idx_l0/l1_default_active_minus1 says that the range is 0 to 31, inclusive. As confirmed at the last meeting, the maximum number of reference pictures is 16, so this range should be 0 to 15, inclusive. Note that this is in two places (one for l0, one for l1).
