Description

The typo "for for" appears twice: first in the semantics of vps_temporal_id_nesting_flag and then in semantics of general_reserved_zero_16bits.

The typo "the the" appears twice: first in 8.5.2.1 and then in 9.3.3.1.4.

Preceding is misspelled as "preceeding" in semantics of dependent_slice_flag.

Other typos in the specification (D8 (J1003) d7)

[1] Semantics of entry_point_offset[i] - " ...Subset 0 consists of bytes 0 to entry_point_offset[ 0 ] − 1, inclusive, of the coded slice data, subset k, with k in the range of 1 to num_entry_point_offsets − 1, inclusive, consists of bytes entry_point_offset[ k − 1 ] to entry_point_offset[ k ] + entry_point_offset[ k − 1 ] − 1, inclusive, of the coded slice data, and the last subset (with subset index equal to num_entry_point_offsets) consists of the remaining bytes of the coded slice data."

entry_point_offset[i] only denotes the difference from the previous entry point for i > 0. In that case, the description of subset k, i.e. the range of bytes contained in subset k, should be described by some cumulative variable, that sums entry_point_offset[i] from i = 0 to k - 1.

[2] Definition of tile scan and z-scan - typo "seqential"

[3] Semantics of nal_unit_type - type "same vlaue of TemporalId"

[4] In section 7.4.1.4.4, the following sentence has a typo:
TileId[ CtbAddrRStoTS[ sliceAddrA] ] is equal to TileId[ CtbAddrRStoTS[ sliceAddrB ] ] and sliceCtbAddrA is less than sliceAddrA.

[5] For the syntax structure of Sub-picture timing SEI message, one occurrence is "sub_pic_timing()" and other one is "subpic_timing()".

[6] Typo in semantics of active_vps_id : "active_vps_id identivies"

[7] In syntax table of profile_tier_level(), the syntax element sub_layer_tier_flag is missing "[i]"

In 7.4.1.4.2, access is misspelled as "acces"

  • Resolution set to fixed
  • Status changed from new to closed

Regarding entry_point_offset[i], I replaced
"consists of bytes entry_point_offset[ k − 1 ] to entry_point_offset[ k ] + entry_point_offset[ k − 1 ] − 1, inclusive, of the coded slice data"
by
"consists of bytes firstByte[ k ] to lastByte[ k ], inclusive, of the coded slice data with firstByte[ k ] and lastByte[ k ] defined as:
firstByte[ k ] = ∑n( entry_point_offset[ n − 1 ] ) with n = 1..k (7 40)
lastByte[ k ] = firstByte[ k ] − 1+entry_point_offset[ k ] (7 41)
"

This will be fixed in JCTVC-K0030_v3 (to be released).
