1) entropy_coding_synchro is specified as “u(v)” coded, but the semantics does not say how. It should be “ue(v)” coded instead.

2) It is said that “The value of entropy_coding_synchro shall be in the range of 0 to tileWidthInLCUs−1, inclusive.” However, what if there are no tiles? What if tiles are of different widths?

3) cabac_istate_reset_flag is about CABAC flushing for wavefront parallel processing. It should not be present if entropy_coding_synchro is equal to 0.

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]

The following sentence at the end of step 3 in C.1:

When BitstreamToDecode is a Type II bitstream and NalHrdModeFlag is equal to 0, all non-VLC NAL units except for filler data NAL units are discarded from BitstreamToDecode, and the remaining bitstream is assigned to BitstreamToDecode.

Should be changed to

When BitstreamToDecode is a Type II bitstream and NalHrdModeFlag is equal to 0, all non-VLC NAL units except filler data NAL units and all leading_zero_8bits, zero_byte, start_code_prefix_one_3bytes, and trailing_zero_8bits syntax elements, when present, are discarded from BitstreamToDecode, and the remaining bitstream is assigned to BitstreamToDecode.
