Introduction
SMPTE ST 2094-10 [4] HDR dynamic metadata provides and describes dynamic information about the video signal.
The usage of this information can be employed by the display to adapt the delivered HDR imagery to the capability of
the display device. The information conveyed in the SEI message carrying SMPTE ST 2094-10 [4] HDR dynamic
metadata is adequate for purposes corresponding to the use of Society of Motion Picture and Television Engineers
SMPTE ST 2094-1 [3] "Dynamic Metadata for Color Volume Transform - Core Components" and SMPTE
ST 2094-10 [4] "Dynamic Metadata for Color Volume Transform - Application #1".

1 Scope
The present document specifies the format of the HEVC SEI message for the carriage of SMPTE ST 2094-10 [4] HDR
dynamic metadata.
The present document provides the guidelines for the carriage and signalling the presence of SMPTE ST 2094-10 [4]
HDR dynamic metadata (carried in SEI messages defined in the present document) for DVB systems, using private data
signalling methods compatible with those defined in ETSI TS 101 154 [8], ETSI TS 103 285 [9] and ETSI
EN 300 468 [6].

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
display mapping: adapting the signal to the dynamic range and the colour gamut of the target display
dynamic range: the ratio of the maximum light intensity to the minimum light intensity [i.1]
NOTE: In digital cameras the dynamic range is normally measured in terms of stops, which describe the total
light range by power of 2.
extended display mapping metadata: subset of the ST2094_data() structure
high dynamic range: typically, a dynamic range of more than 10 stops is referred to as high dynamic range
standard dynamic range: typically, a dynamic range of up to 10 stops is referred to as standard dynamic range
3.2 Symbols
3.2.1 Arithmetic operators
For the purposes of the present document, the following arithmetic operators apply:
+ Addition
- Subtraction (as a two-argument operator) or negation (as a unary prefix operator)
x Multiplication, including matrix multiplication
÷ Used to denote division in mathematical equations where no truncation or rounding is intended
/ Integer division with truncation of the result toward zero
EXAMPLE: 7/4 and - 7/- 4 are truncated to 1 and - 7/4 and 7/- 4 are truncated to - 1.
3.2.2 Relational operators
For the purposes of the present document, the following relational operators apply:
> Greater than
>= Greater than or equal to
< Less than
<= Less than or equal to
== Equal to
!= Not equal to

3.2.3 Assignment operators
For the purposes of the present document, the following assignment operators apply:
= Assignment operator
++ Increment, i.e. x is equivalent to x = x + 1; when used in an array index, evaluates to the value of
the variable prior to the increment operation
-- Decrement, i.e. x- - is equivalent to x = x - 1; when used in an array index, evaluates to the value
of the variable prior to the decrement operation
+= Increment by amount specified, i.e. x += 4 is equivalent to x = x + 4, and x += (-4) is equivalent to
x = x + (-4)
-= Decrement by amount specified, i.e. x -= 4 is equivalent to x = x - 4, and x -= (-4) is equivalent to
x = x - (-4)
3.2.4 Mathematical functions
For the purposes of the present document, the following mathematical functions apply:
;≥0
Abs(x) =
−;<0
;<
Clip3(x, y, z) = ;>
; ℎ
Floor(x) the largest integer less than or equal to x.
Round(x)=Sign(x)*Floor(Abs(x)+0,5)
1 ; x > 0
Sign(x) = 0 ;=0
−1 ;<0

4.1 Introduction
This clause specifies the syntax and semantics of ST2094-10_data() structure.
Clause 4.1 defines the syntax of the ST2094-10_data() structure.
Clause 4.2 defines the semantics of the ST2094-10_data() structure.
NOTE: The metadata elements of the ST2094-10_data() structure are defined according to the SMPTE standards
ST 2086 [2], ST 2094-1 [3] and ST 2094 -10 [4].
4.2 ST2094-10_data() structure syntax
The parsing process of each syntax element by the descriptor u(n) is described in Recommendation ITU-T H.265 [5].

  dm_alignment_zero_bit f(1)
  for( i = 0; i < num_ext_blocks; i ++ ) {
  ext_dm_data_block(i)
  }
 }
}
while( !byte_aligned() )
 dm_alignment_zero_bit f(1)
