D.2.27 Mastering display colour volume SEI message semantics
This SEI message identifies the colour volume (the colour primaries, white point, and luminance
range) of a display considered to be the mastering display for the associated video content, e.g. the
colour volume of a display that was used for viewing while authoring the video content. The described
mastering display is a three-colour additive display system that has been configured to use the
indicated mastering colour volume.
This SEI message does not specify the measurement methodologies and procedures used for
determining the indicated values or any description of the mastering environment. It also does not
provide information on colour transformations that would be appropriate to preserve creative intent
on displays with colour volumes different from that of the described mastering display.
The information conveyed in this SEI message is intended to be adequate for purposes corresponding
to the use of Society of Motion Picture and Television Engineers ST 2086.
The following constraints apply for the presence of mastering display colour volume SEI messages in
IDR access units:
— when a mastering display colour volume SEI message is present in any access unit of a coded video
sequence and the mastering display colour volume SEI message is not contained within any other SEI
message, a mastering display colour volume SEI message that is not contained within any other SEI
message shall be present in the IDR access unit that is the first access unit of the coded video sequence;
— when a mastering display colour volume SEI message is present in any access unit of a coded
video sequence and the mastering display colour volume SEI message is contained in a scalable

nesting SEI message applying to dependency_id dId, quality_id qId, and temporal_id tId, a mastering
display colour volume SEI message that is contained in a scalable nesting SEI message applying to
dependency_id equal to dId, quality_id equal to qId, and temporal_id equal to tId shall be present in
the IDR access unit that is the first access unit of the coded video sequence;
— when a mastering display colour volume SEI message is present in any access unit of a coded video
sequence and the mastering display colour volume SEI message is contained in an MVC scalable
nesting SEI message applying to view_id vId and temporal_id tId, a mastering display colour volume
SEI message that is contained in an MVC scalable nesting SEI message applying to view_id equal to
vId and temporal_id equal to tId shall be present in the IDR access unit that is the first access unit of
the coded video sequence;
— when a mastering display colour volume SEI message is present in any access unit of a coded video
sequence and the mastering display colour volume SEI message is contained in an MVCD scalable
nesting SEI message applying to texture views with view_id vId and temporal_id tId, a mastering
display colour volume SEI message that is contained in an MVCD scalable nesting SEI message
applying to texture views with view_id equal to vId and temporal_id equal to tId shall be present in
the IDR access unit that is the first access unit of the coded video sequence.
The mastering display colour volume SEI message persists in decoding order from the current access
unit until the end of the coded video sequence.
When a mastering display colour volume SEI message is not contained within any other SEI message, it
pertains only to VCL NAL units with nal_unit_type in the range of 1 to 5, inclusive.
NOTE When the bitstream is a scalable video bitstream according to Annex G, a mastering display colour
volume SEI message that is not contained within any other SEI message applies only to the base layer bitstream.
When the bitstream is a multiview video bitstream according to Annex H, a mastering display colour volume SEI
message that is not contained within any other SEI message applies only to the base layer bitstream. When the
bitstream is a multiview video bitstream with depth according to Annex I or Annex J, a mastering display colour
volume SEI message that is not contained within any other SEI message applies only to the base texture view.
The following constraints apply for the content of mastering display colour volume SEI messages:
— all mastering display colour volume SEI messages that apply to the same coded video sequence and
are not contained within any other SEI message shall have the same content;
— all mastering display colour volume SEI messages that apply to the same coded video sequence and
are contained in a scalable nesting SEI message applying to particular values of dependency_id,
quality_id, and temporal_id shall have the same content;
— all mastering display colour volume SEI messages that apply to the same coded video sequence and
are contained in an MVC scalable nesting SEI message applying to particular values of view_id and
temporal_id shall have the same content;
— all mastering display colour volume SEI messages that apply to the same coded video sequence and
are contained in an MVCD scalable nesting SEI message applying to texture views with particular
values of view_id and temporal_id shall have the same content.
display_primaries_x[ c ] and display_primaries_y[ c ] specify the normalized x and y chromaticity
coordinates, respectively, of the colour primary component c of the mastering display in increments of
0.00002, according to the CIE 1931 definition of x and y as specified in ISO 11664-1 (see also ISO 11664-3
and CIE 15). For describing mastering displays that use red, green, and blue colour primaries, it is
suggested that index value c equal to 0 should correspond to the green primary, c equal to 1 should
correspond to the blue primary, and c equal to 2 should correspond to the red colour primary (see also
Annex E and Table E-3). The values of display_primaries_x[ c ] and display_primaries_y[ c ] shall be in
the range of 0 to 50 000, inclusive.
white_point_x and white_point_y specify the normalized x and y chromaticity coordinates,
respectively, of the white point of the mastering display in normalized increments of 0.00002, according
© ISO 2015 – All rights reserved 5
---------------------- Page: 8 ----------------------
ISO/IEC 14496-10:2014/Amd.1:2015(E)
to the CIE 1931 definition of x and y as specified in ISO 11664-1 (see also ISO 11664-3 and CIE 15). The
values of white_point_x and white_point_y shall be in the range of 0 to 50 000.
max_display_mastering_luminance and min_display_mastering_luminance specify the nominal
maximum and minimum display luminance, respectively, of the mastering display in units of 0.0001
candelas per square metre. min_display_mastering_luminance shall be less than max_display_
mastering_luminance.
At minimum luminance, the mastering display is considered to have the same nominal chromaticity as
the white point.

Replace the semantics of transfer_characteristics with the following:
transfer_characteristics indicates the opto-electronic transfer characteristic of the source picture as
specified in Table E-4 as a function of a linear optical intensity input L with a nominal real-valued
c
range of 0 to 1. For interpretation of entries in Table E-4 that are expressed in terms of multiple curve
segments parameterized by the variable α over a region bounded by the variable β or by the variables
β and γ, the values of α and β are defined to be the positive constants necessary for the curve segments
that meet at the value β to have continuity of value and continuity of slope at the value β, and the value
of γ, when applicable, is defined to be the positive constant necessary for the associated curve segments
to meet at the value γ. For example, for transfer_characteristics equal to 1, 6, 14, or 15, α has the value
1 + 5.5 * β = 1.099 296 826 809 442. and β has the value 0.018 053 968 510 807.
When the transfer_characteristics syntax element is not present, the value of transfer_characteristics is
inferred to be equal to 2 (the transfer characteristics are unspecified or are determined by the application).
Values of transfer_characteristics that are identified as reserved in Table E-4 are reserved for future use
by ITU-T | ISO/IEC and shall not be present in bitstreams conforming to this version of this Specification.
Decoders shall interpret reserved values of transfer_characteristics as equivalent to the value 2.

Replace the semantics of matrix_coefficients with the following:
matrix_coefficients describes the matrix coefficients used in deriving luma and chroma signals from
the green, blue, and red, or Y, Z, and X primaries, as specified in Table E-5.
matrix_coefficients shall not be equal to 0 unless one or more of the following conditions are true:
— BitDepth is equal to BitDepth ;
C Y
— chroma_format_idc is equal to 3 (4:4:4).
The specification of the use of matrix_coefficients equal to 0 under all other conditions is reserved for
future use by ITU-T | ISO/IEC.
matrix_coefficients shall not be equal to 8 unless one of the following conditions is true:
— BitDepth is equal to BitDepth ;
C Y
— BitDepth is equal to BitDepth + 1 and chroma_format_idc is equal to 3 (4:4:4).
C Y
The specification of the use of matrix_coefficients equal to 8 under all other conditions is reserved for
future use by ITU-T | ISO/IEC.
When the matrix_coefficients syntax element is not present, the value of matrix_coefficients is inferred
to be equal to 2 (unspecified).

The interpretation of matrix_coefficients, together with colour_primaries and transfer_characteristics,
is specified by the formulae below.
NOTE 3 For purposes of YZX representation when matrix_coefficients is equal to 0, the symbols R, G, and B are
substituted for X, Y, and Z, respectively, in the following descriptions of Formulae (E-1) to (E-3), (E-7) to (E-9), (E-
13) to (E-15), and (E-19) to (E-21).
E , E , and E are defined as “linear-domain” real-valued signals based on the indicated colour
R G B
primaries before application of the transfer characteristics function. The application of the transfer
characteristics function is denoted by ( x )′ for an argument x. The signals E′ , E′ , and E′ are
R G B
determined by application of the transfer characteristics function as follows:
E′ = ( E )′ (E-1)
R R
E′ = ( E )′ (E-2)
G G
E′ = ( E )′ (E-3)
B B
The range of E′ , E′ , and E′ is specified as follows.
R G B
— If transfer_characteristics is not equal to 11 or 12, E′ , E′ , and E′ are real numbers with values in
R G B
the range of 0 to 1, inclusive.
— Otherwise, [transfer_characteristics is equal to 11 (IEC 61966-2-4) or 12 (Rec. ITU-R BT.1361
extended colour gamut system)], E′ , E′ and E′ are real numbers with a larger range not specified
R G B
in this specification.
Nominal white is specified as having E′ equal to 1, E′ equal to 1, and E′ equal to 1.
R G B
Nominal black is specified as having E′ equal to 0, E′ equal to 0, and E′ equal to 0.

The interpretation of matrix_coefficients is specified as follows.

— Otherwise, if matrix_coefficients is equal to 2, the interpretation of the matrix_coefficients
syntax element is unknown or is determined by the application.
