o Modified check for equal reference pictures to be always based on POC difference
o
o
o Correct the description of (forward increment only) modulo wrapping calculation for CPB removal delay

Took care of some editor's notes.
Fixed several minor issues (#955, #698, #956, #894, #964, #957, #944, #966)
Increased bit expansion limit ratio from 4/3 to 5/3 (regardless of profile) according to the decision noted under
JCTVC-L0292.
Draft ISO/IEC 23008-2 : 201x (E)
Conditioned the presence of the syntax elements low_delay_hrd_flag[ i ] and cpb_cnt_minus1[ i ] on
fixed_pic_rate_within_cvs_flag[ i ] and low_delay_hrd_flag[ i ], respectively, according to JCTVC-L0372
Corrected the condition for the "memorization" process for context variables when dependent slice segments are
supported, and changed the syntax element entry_point_offset[ i ] to entry_point_offset_minus1[ i ], according to the
decisions noted under JCTVC-L0116.
Removed profilePresenceFlag from the profile_tier_level( ) syntax structure according to the decision noted under
JCTVC-L0227.
Integrated the following decisions noted under JCTVC-L0043:
allowed value range as 0..4095
o Classify NAL unit types 48–55 (the first 8 of the 16 NAL unit types that have "unspecified" usage) as
"prefixes" (i.e. may start a new access unit)
o Remove bit_rate_pic_rate_info( ) from VPS
o Change the coding of the min_spatial_segmentation_idc syntax element from u(8) to ue(v), and specify the
o Require that the TemporalId of any non-VCL NAL unit shall not be less than the TemporalId of the access
unit containing the NAL unit (which implies that a VPS, SPS or PPS NAL unit is disallowed to be present
in access units with TemporalId greater the TemporalId of the VPS, SPS or PPS NAL unit)
Signal clock tick value outside of HRD parameters (so that it will be available for use with indication of
POC proportional to timing) and make the syntax structure for this the same in the VPS as in the SPS
(nesting HRD parameters within the timing presence if statements, and adjusting semantics such that when
POC is indicated to be proportional to timing in the VPS, this shall also be indicated in the SPS)
o
Removed frame_packing_arrangement_type = 0, 1, 2 (interleaved types) and 7 ("tiled" frame packing) without
renumbering the remaining one, according to the decision noted under JCTVC-L0444.
Updated list of HEVC applications based on the HEVC requirements N11096.
Moved output_flag_present_flag and num_extra_slice_header_bits up to immediately after
dependent_slice_segments_enabled_flag in the PPS according to the decision noted under JCTVC-L0255.
Integrated updated text of the SOP description SEI message (JCTVC-L0208).
Requirement to set delta_poc_msb_present_flag[ i ] equal to 1 in a problematic corner case (option 2 of JCTVC-
L0443 w/ later cleanup).
Integrated changes for num_ref_idx_lX_(default_)active_minus1 and *_max_dec_pic_buffering and according to
the decision noted under (JCTVC-L0323).
Copied scene information SEI message syntax and semantics from AVC.
Copied film grain characteristics SEI message syntax and semantics from AVC.
Integrated changes to the scene information SEI message to limit its scope to be within a CVS (JCTVC-L0431).
Integrated the following decisions noted under JCTVC-L0328 (w/ later cleanup):
Integrated the following decisions noted under JCTVC-L0044:
RASL, RADL or sub-layer non-reference pictures.
o Restrict buffering period SEI messages to be sent only for pictures with temporal ID equal to 0 that are not
o Concatenation flag and associated CPB removal delay delta for bitstream splicing.
o Addition of the cpb_delay_offset and dpb_delay_offset syntax elements in the buffering period SEI
message, and their use in derivation of CPB removal times and DPB output times, respectively.
o Modified CPB removal time calculation to remove dependence of AU removal time on DU CPB
parameters while maintaining alignment of nominal CPB removal time of AU and last DU.
Integrated the following decisions noted under JCTVC-L0045:
o When non-nested, the BP, PT, DU SEI message would apply to the whole bitstream. The version 1 decoder
would ignore all NAL units with NR6 > 0. The encoder for version 1 would be required to set NR6 = 0.
The sub-bitstream extraction process would remove SEI NAL units with NR6 = 0 that contain non-nested
BP, PT, DU SEI messages when the actual max layer ID = 0 and the target temporal ID is less than the
highest actual temporal ID in the bitstream.
unit and cannot be nested.
o Restrictions would apply on nesting of SEI messages (listed in contribution, as modified in discussion).
o The APS SEI message, when present, is required to be in the first SEI NAL unit and to be alone in the NAL
o Non-nested BP, PT, DU SEI cannot be in the same NAL unit as any other SEI message. Their order
immediately follows APS SEI (if present) and precedes all others. Between these the order is required to be
BP, then PT, then DU (when each is present).
the same NAL unit as any SEI message other than these three.
o Nested BP, PT, DU SEI must immediately follow the non-nested ones (when present) and shall not be in
o An SEI message of a given type cannot be used as both a prefix and suffix SEI message in the same AU.
o Allow suffix SEI NAL units between VCL NAL units of an AU (in general).
o
If it's a prefix with whole-picture or higher scope, repetitions may be present between, but they must be
repetitions. Similarly, if it's a suffix … it may be preceded by repetitions between VCL NAL units.
o
Improved semantics for recovery point SEI – adopted (needs some editorial refinement).
o
Improved semantics for region refresh information SEI – adopted (needs some editorial refinement).
ii
Draft Rec. ITU-T H.HEVC (201x E)
Draft ISO/IEC 23008-2 : 201x (E)
o Modified syntax and semantics of progressive refinement segment start SEI message (w/ later cleanup).
o
For all five SEI messages with this type of persistence, convert the "repetition period" into a persistence
flag, such that 0 and 1 are supported and >1 is not.
o Copied syntax and semantics of the post-filter hint SEI message from the AVC spec, and clarified the
o
persistency scope of the post-filter hint SEI message to be just the picture that contains the SEI message.
Picture timing SEI, condition the presence of some syntax elements on CpbDpbDelaysPresentFlag.
Integrated bounding redundant SEI messages (JCTVC-L0325).
Integrated indication of parameter sets properties in active parameter sets SEI (JCTVC-L0047).
Fixed matrix_coefficients semantics.
Removed frame_packing_arrangement_type = 6 according to the decision noted under JCTVC-L0454.
Integrated the following decisions noted under JCTVC-L0046 (w/ later cleanup):
o Renamed progressive_source_idc to source_scan_type
o
In profile/tier/level syntax structure (general_ and sub_layer_ prefixed), specify progressive_source_flag
and interlaced_source_flag (these two go first among the four), as follows:
both zero indicates that the source scan type is unknown or unspecified
both equal to 1 indicates that the source type is indicated at picture level in source_scan_type
o These two bits are followed by the following two bits (general_ and sub_layer_ prefixed):
non_packed_constraint_flag equal to 1 specifies that FPA SEI, if present, has frame_packing_type
equal to 6. non_packed_constraint_flag equal to 0 indicates that this constraint is not applied.
frame_only_constraint_flag equal to 1 specifies that field_seq_flag is equal to 0.
frame_only_constraint_flag equal to 0 indicates that field_seq_flag may or may not be equal to 0.
Integrated the following decisions noted under JCTVC-L0219 (w/ later cleanup): In bumping HRD operation, the
bumping process should be invoked until there are no detected constraint violations rather than just until there is an
empty frame buffer, and the checked conditions should checking immediately after decoding and should include
checking both maximum picture reordering and maximum picture latency.
Copied syntax and semantics of the filler payload SEI message, the user data registered by Rec. ITU-T T.35 SEI
message, the user data unregistered SEI message, the full-frame snapshot SEI message, and the progressive
refinement segment end SEI message from the AVC spec.
Fixed the following:
o Dropped the extension flag in the syntaxes of the post-filter hint SEI message and the display orientation
SEI message, and fixed the syntax of the post-filter hint SEI message related to chroma_format_idc equal
to 0.
o Updated the list of normative references.
Fixed editorial issues from NB comments JP15, JP27 and JP23 (#875).
Fixed several issues (#797, #914, #971, #975, #978).
Moved the bumping process one level up.
