Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Part 2:
High efficiency video coding
AMENDMENT 3: Additional supplemental enhancement
information
General
Throughout the specification, replace all single-word instances of "nested" with "scalable-nested" (e.g.,
there is no single-word instance of "nested" in "non-nested"), and all instances of "non-nested" with
"non-scalable-nested", except in 3.158 (which is kept unchanged) and Table F.4 in F.14.3.1 (for which a
change is provided below).
Clause 3
Add the following term definitions (in alphabetical order within the current list) and correct all term
numbering sequentially:
3.X
azimuth circle
circle on a sphere connecting all points with the same azimuth value
Note 1 to entry: An azimuth circle is always a great circle like a longitude line on the earth.
3.X
constituent picture
part of a spatially frame-packed stereoscopic video picture that corresponds to one view, or a picture
itself when frame packing is not in use or the temporal interleaving frame packing arrangement is in use
3.X
elevation circle
circle on a sphere connecting all points with the same elevation value
Note 1 to entry: An elevation circle is similar to a lattitude line on the earth. Except when the elevation
value is zero, an elevation circle is not a great circle like a longitude circle on the earth.
3.X
global coordinate axes
coordinate axes associated with omnidirectional video that are associated with an externally reference-
able position and orientation
Note 1 to entry: The global coordinate axes may correspond to the position and orientation of a device
or rig used for omnidirectional audio/video acquisition as well as the position of an observer's head in
the three-dimensional space of the omnidirectional video rendering environment.
3.X
great circle
intersection of a sphere and a plane that passes through the centre point of the sphere
© ISO/IEC 2018 – All rights reserved 1

ISO/IEC 23008-2:2017/Amd.3:2018(E)

Note 1 to entry: A great circle is also known as an orthodrome or Riemannian circle.
3.X
local coordinate axes
coordinate axes having a specified rotation relationship relative to the global coordinate axes
3.X
omnidirectional video
video content in a format that enables rendering according to the user's viewing orientation, e.g., if
viewed using a head-mounted device, or according to a user's desired viewport, reflecting a potentially
rotated viewing position
3.X
packed region
region in a region-wise packed picture that is mapped to a projected region according to a re-
gion-wise packing
3.X
projected picture
picture that uses a projection format for omnidirectional video
3.X
projected region
region in a projected picture that is mapped to a packed region according to a region-wise packing
3.X
projection
specified correspondence between the colour samples of a projected picture and azimuth and elevation
positions on a sphere
3.X
region-wise packed picture
decoded picture that contains one or more packed regions
Note 1 to entry: A packed picture may contain a region-wise packing of a projected picture.
3.X
region-wise packing
transformation, resizing, and relocation of packed regions of a region-wise packed picture to remap the
packed regions to projected regions of a projected picture
3.X
sphere coordinates
azimuth and elevation angles identifying a location of a point on a sphere
3.X
sphere region
region on a sphere, specified either by four great circles or by two azimuth circles and two elevation
circles, or such a region on a rotated sphere after applying yaw, pitch, and roll rotations
3.X
tilt angle
angle indicating the amount of tilt of a sphere region, measured as the amount of rotation of a sphere
region along the axis originating from the sphere origin passing through the centre point of the sphere
region, where the angle value increases clockwise when looking from the origin towards the positive
end of the axis
3.X
viewport
region of omnidirectional video content suitable for display and viewing by the user

the range of −1.0 to 1.0, inclusive, with an output value in the range of −π ÷ 2 (5-2)
to π ÷ 2, inclusive, in units of radians
Atan( x ) the trigonometric inverse tangent function, operating on an argument x, with
(5-3)
an output value in the range of −π ÷ 2 to π ÷ 2, inclusive, in units of radians

Sin( x ) the trigonometric sine function operating on an argument x in units of radians (5-19)
Renumber the prior Formulae 5-19 through 5-20 as 5-20 to 5-21 to account for the added formulae.
Add the following function definition:
Tan( x ) the trigonometric tangent function operating on an argument x in units of
(5-22)

7.4.2.4.4, NOTE 2
Delete the sentence that says “Consequently, hypothetical reference decoder (HRD) parameters carried
in non-nested buffering period, picture timing and decoding unit information SEI messages apply to
access units based on such access unit boundary detection.”
7.4.4
Replace paragraph 6 (directly after NOTE 1) and NOTE 2 with the following:
general_non_packed_constraint_flag equal to 1 specifies that there are no frame packing
arrangement SEI messages, segmented rectangular frame packing arrangement SEI messages,
omnidirectional projection indication SEI messages, or cubemap projection SEI messages present in
the CVS. general_non_packed_constraint_flag equal to 0 indicates that there may or may not be one or
more frame packing arrangement SEI messages, segmented rectangular frame packing arrangement
© ISO/IEC 2018 – All rights reserved 3

ISO/IEC 23008-2:2017/Amd.3:2018(E)

SEI messages, omnidirectional projection indication SEI messages, or cubemap projection SEI messages
present in the CVS.
NOTE 2 Decoders could ignore the value of general_non_packed_constraint_flag, as there are no decoding
process requirements associated with the presence or interpretation of frame packing arrangement SEI
messages, segmented rectangular frame packing arrangement SEI messages, equirectangular projection SEI
messages, or cubemap projection SEI messages present in the CVS.
8.7.2.1
Replace paragraph 4 (directly after the NOTE) with the following:
The deblocking filter process is applied to all prediction block edges and transform block edges of a
picture, except the following types of edges:
— Edges that are at the boundary of the picture;
— Edges that coincide with tile boundaries when loop_filter_across_tiles_enabled_flag is equal to 0;
— Edges that coincide with upper or left boundaries of slices with slice_loop_filter_across_slices_
enabled_flag, equal to 0 or slice_deblocking_filter_disabled_flag equal to 1;
— Edges within slices with slice_deblocking_filter_disabled_flag equal to 1;
— Edges that do not correspond to 8 × 8 sample grid boundaries of the considered component;
— Edges within chroma components for which both sides of the edge use inter prediction;
— Edges of chroma transform blocks that are not edges of the associated transform unit.
C.1
Add the following NOTE 1 immediately before the sentence that says “Figure C.1 shows the types of
bitstream conformance points checked by the HRD.”, and renumber the existing NOTEs in the clause
accordingly:
NOTE 1 Decoders conforming to profiles specified in Annex A do not use NAL units with nuh_layer_id greater
than 0 (e.g., access unit delimiter NAL units with nuh_layer_id greater than 0) for access unit boundary detection,
except for identification of whether a NAL unit is a VCL or non-VCL NAL unit. Consequently, hypothetical reference
decoder (HRD) parameters carried in non-scalable-nested buffering period, picture timing and decoding unit
information SEI messages apply to access units that are identified based on such access unit boundary detection.

Add the following paragraph immediately after Table D.1:
The values of some SEI message syntax elements, including pan_scan_rect_id, scene_id, second_scene_
id, snapshot_id, progressive_refinement_id, tone_map_id, frame_packing_arrangement_id, mcts_id[ i ],
knee_function_id, colour_remap_id, ilcts_id[ i ], and regional_nesting_id, are split into two sets of value
ranges, where the first set is specified as "may be used as determined by the application", and the
second set is specified as "reserved for future use by ITU-T | ISO/IEC". Applications should be cautious
of potential “collisions” of the interpretation for values of these syntax elements belonging to the first
set of value ranges. Since different applications might use these IDs having values in the first set of
value ranges for different purposes, particular care should be exercised in the design of encoders that
generate SEI messages with these IDs having values in the first set of value ranges, and in the design of
decoders that interpret SEI messages with these IDs. This Specification does not define any management
for these values. These IDs having values in the first set of value ranges might only be suitable for use
in contexts in which "collisions" of usage (i.e., different definitions of the syntax and semantics of an SEI
message with one of these IDs having the same value in the first set of value ranges) are unimportant,
or not possible, or are managed – e.g., defined or managed in the controlling application or transport
specification, or by controlling the environment in which bitstreams are distributed.

Replace paragraph 1 with the following:
The temporal motion-constrained tile sets SEI message indicates that the following constraints apply:
— No sample values outside each identified tile set or outside the picture are referenced for inter
prediction.
— For PUs located directly left of the right tile boundary of each identified tile set except the last one
at the bottom right, the following applies when CuPredMode[ xPb ][ yPb ] is equal to MODE_INTER,
where ( xPb, yPb ) specifies the top-left sample of the corresponding luma prediction block relative
to the top-left sample of the current picture:
—  With the number of spatial merging candidates numSpatialMergeCand derived as follows:
numSpatialMergeCand = availableFlagA + availableFlagA +
0 1
(D-42)
availableFlagB + availableFlagB + availableFlagB
0 1 2
where availableFlagA , availableFlagA , availableFlagB , availableFlagB , and availableFlagB
0 1 0 1 2

where availableFlagLXA, availableFlagLXB, mvLXA, and mvLXB are the output of the
derivation process for motion vector predictor candidates from neighbouring prediction
unit partitions specified in subclause 8.5.3.2.7, the following applies:
—  If numSpatialMvpCand is equal to 0, mvp_l0_flag[ xPb ][ yPb ] and
mvp_l1_flag[ xPb ][ yPb ] is equal to 1.
—  Otherwise (numSpatialMvpCand is greater than 0), mvp_l0_flag[ xPb ][ yPb ] and
mvp_l1_flag[ xPb ][ yPb ] is in the range of 0 to numSpatialMvpCand − 1, inclusive.
NOTE 1 The first constraint restricts motion vectors to point to full-sample locations inside each identified
tile set and to fractional-sample locations that require only full-sample locations inside each identified tile set for
interpolation. The second constraint restricts the usage of motion vector candidates derived from blocks outside
each identified tile set.

one or more tiles in any particular temporal motion-constrained tile set shall not be a dependent slice
segment of an independent slice segment that contains one or more tiles that do not belong to that
temporal motion-constrained tile set.
For purposes of referencing a particular temporal motion-constrained tile set that is identified in a
temporal motion-constrained tile sets SEI message (e.g., for use with a motion-constrained tile sets
extraction information sets SEI message or a motion-constrained tile sets extraction information
nesting SEI message), an MCTS index is defined as follows:
— If the value of each_tile_one_tile_set_flag of the temporal motion-constrained tile sets SEI message is
equal to 0, the MCTS index is the value of the variable i within the loop of the num_sets_in_message_
minus1 + 1 sets of MCTS information specified by the temporal MCTS SEI message.
— Otherwise, the MCTS index of each MCTS is the tile position of the tile in tile raster scan order.

D.3.40  Content colour volume SEI message semantics
The content colour volume SEI message describes the colour volume characteristics of the associated
pictures. These colour volume characteristics are expressed in terms of a nominal range, although
deviations from this range may occur.
The variable transferCharacteristics is specified as follows:
— If an alternative transfer characteristics SEI message is present for the CLVS, transferCharacteristics
is set equal to preferred_transfer_characteristics;
— Otherwise, (an alternative transfer characteristics SEI message is not present for the CLVS),
transferCharacteristics is set equal to transfer_characteristics.

ISO/IEC 23008-2:2017/Amd.3:2018(E)

The content colour volume SEI message shall not be present, and decoders shall ignore it, when any of
the following conditions is true:
— Any of the values of transferCharacteristics, colour_primaries, and matrix_coeffs has a value defined
as unspecified.
— The value of transfer_characteristics is equal to 2, 4, or 5.
— The value of colour_primaries is equal to 2.
The following applies when converting the signal from a non-linear to a linear representation:
— If the value of transferCharacteristics is equal to 1, 6, 7, 14, or 15, the Rec. ITU-R BT.1886-0 reference
electro-optical transfer function should be used to convert the signal to its linear representation,
where the value of screen luminance for white is set equal to 100 cd/m , the value of screen
luminance for black is set equal to 0 cd/m , and the value of the exponent of the power function is
set equal to 2.4.
— Otherwise, if the value of transferCharacteristics is equal to 18, the hybrid log-gamma reference
electro-optical transfer function specified in Rec. ITU-R BT.2100-1 should be used to convert the
signal to its linear representation, where the value of nominal peak luminance of the display is set
2 2
equal to 1 000 cd/m , the value of the display luminance for black is set equal to 0 cd/m , and the
value of system gamma is set equal to 1.2.
