New key features and benefits
Firmware Version 2.9.x introduces a new HDR (High Dynamic Range) tool set for
assisting camera operators and editors to adjust their content to the correct levels.
The new HDR features and functions are described on the following pages.
NOTE. Option PROD is required to access HDR features.

Waveform display Dynamic Range setting. The pop-up menu for the Waveform display now
contains a selection for setting the Dynamic Range as shown below (Option
PROD required).
NOTE. When HDR, HDR Full, SDR Narrow, or SDR Full is selected, you can use
the Left / Right arrow keys to toggle the vertical scale of the graticule between
NITS, STOPS, REFLECTANCE, CODE VALUE, and PERCENT. The selected
scale is shown at the bottom of the display. (See Figure 3.)

Release notes
The following settings are available:
SDR (Standard Dynamic Range). Use this setting for conventional SD,
HD and 3G signals using ITU-R BT.709/2020 with OETF (Optical to
Electrical Transfer Function) gamma of 0.45 and with a display gamma EOTF
(Electrical to Optical Transfer Function) of 2.4 as defined in ITU-R BT.1886.
When SDR is selected as the dynamic range, the CONFIG > Graticules and
Readouts menu contains the following graticule settings:
STD. The Standard graticule is available in either millivolts (Normal) or
Percent and can be configured within CONFIG > Graticules and Readouts
> SDI Waveform Graticules.
NARROW. The Narrow graticule uses a Nits graticule scale and code
values, which is the traditional signal representation. This setting provides
a signal representation using a code value of 64 decimal (10-bit) equal to
0 mV or 0%, and a code value of 940 decimal (10-bit) equal to 700 mV
or 100%.
FULL. The Full graticule uses a NITs graticule scale and code values that
provides signal representation with a code value of 4d decimal (10-bit)
equal to 0%, and a code value of 1019 decimal (10-bit) equal to 100%.
NOTE. In SDI signals, the code words 0-3d and 1020-1023 are excluded and
clipped from a file that uses 0-1023 as the full range as definedinITU-R
BT.2100.
HDR (High Dynamic Range). Use this setting to change the graticule
scale of one of the selected curves. When HDR is selected as the dynamic
range, the CONFIG > Graticules and Readouts menu contains the following
graticule settings:
HLG(1000). The Hybrid Log Gamma (HLG) graticule is configured for a
maximum value of 1000 Nits as defined by standard ITU-R BT.2100-0.
HLG(1200). The Hybrid Log Gamma graticule is defined in standard
ARIBSTDB-67andwasdevelopedbytheBBCandNHK.
ST2084(1K). This graticule uses the ST 2084 curve with a maximum
value of 1000 Nits using the narrow range.
ST2084(2K). This graticule uses the ST 2084 curve with a maximum
value of 2000 Nits using narrow range.
ST2084(4K). This graticule uses the ST 2084 curve with a maximum
value of 4000 Nits using narrow range.

Release notes
ST2084(5K).Th
is graticule uses the ST 2084 curve with a maximum
value of 5000 Nits using narrow range.
ST2084(10K).This graticule uses the ST 2084 curve with a maximum
value of 10000 Nits using narrow range. SMPTE standard ST 2084
defines High Dynamic Range Electro-Optical Transfer Function of
Mastering Reference Displays also know as Perceptual Quantization (PQ).
NOTE. Narrow range is defined by ITU-R BT.2100 as signal representation
with code value 64 decimal (10-bit) equal to 0 mV or 0%, and code value 940
decimal (10-bit) equal to 700 mV or 100%.
NOTE. HLG(1000), HLG(1200) and ST2084(10K) are the preferred
configurations for HDR. ST2084(1K), ST2084(2K), ST2084(4K), and
ST2084(5K) settings are intended for future use or legacy modes.
NOTE. For compatibility between HDR configurations, a reference point of
203 Nits is displayed in HLG1000 and ST2084(10K) modes.
HDR Full (High Dynamic Range Full). Use this setting if you need the
High Dynamic Full Range defined by ITU-R BT.2100, which provides signal
representation with code value 4d decimal (10-bit) equal to 0%, and code
value 1019 decimal (10-bit) equal to 100%.
NOTE. In SDI signals, the code words 0-3d and 1020-1023 are excluded and
clipped from a file that uses 0-1023 as the full range as defined in ITU-R BT.2100.
When HDR Full is selected as the dynamic range, the CONFIG > Graticules
and Readouts menu contains the following graticule settings:
ST2084(1K) Full. This graticule uses the ST 2084 curve with a maximum
value of 1000 Nits using full range.
ST2084(10K) Full. This graticule uses the ST 2084 curve with a
maximum value of 10000 Nits using full range.

Camera Log.Use
this setting to use a graticule with a curve based on the
camera manufacturers specification. When Camera Log is selected as the
dynamic range, the CONFIG > Graticules and Readouts menu contains the
following graticule settings:
SLog. This graticule uses the Sony S Log curve.
SLog2. This graticule uses the Sony S Log2 curve.
SLog3.Thisgraticule uses the Sony S Log3 curve.
CLog. This graticule uses the Canon C Log curve.
Log C.ThisgraticuleusestheARRILogCcurveat(ISO)El800.
BT.709. This graticule uses the traditional ITU-R BT.709 representation.
HDR graticule selection. The CONFIG > Graticules and Readouts menu now
contains a setting for selecting the HDR graticule to be used by the Waveform
display: HLG(1000), HLG(1200), ST2084(1K), ST2084(2K), ST2084(5K), or
ST2084(10K).

Release notes
HDR graticule vertical scale setting. When an HDR graticule is selected for the
Waveform display, you can use the Left / Right arrow keys to toggle the vertical
scale units between NITS, STOPS, or REFLECTANCE. Camera operators can
use the graticule lines at 2%, 18% or 90% Reflectance to properly setup camera
exposure with a camera test chart of 2% black, 18% gray and 90% white.
Figure 3: Waveform display showing the HDR graticule with NITS selected as the vertical scale
Gain adjustment. When the ST2084(1K) or ST2084(10K) HDR graticules are
selected, a fixed zoom mode from 100 Nits to maximum scale is available by
using the Up arrow key to enable Zoom Mode and the Down arrow key to disable
Zoom Mode. When Zoom Mode is enabled, the Gain function and the Vertical
Position controls are locked in a fixed configuration. When in HDR modes,
Variable Gain will be enabled by default to facilitate the Zoom mode function.
Voltage cursors. When HDR or HDR Full mode is selected as the Dynamic
Range setting, the mV voltage measurement cursors are replaced by a set of Nits
measurement cursors.

Picture display brightup
settings
The CONFIG > Display Settings > Picture Brightup on Luma/Specular Gamut
Error menu has new selections for HDR monitoring:
Off. For this setting, the highlight overlay is turned off in the picture display.
Luma. For this setting, the highlight overlay is turned on for Luma values
that exceed signal levels based on gamut thresholds for Luma settings.
HDR Specular On. For this setting, the highlight overlay is turned on for
selected HDR settings and produces HDR zebra highlights in the picture for
large areas of the trace that exceed 100 nits. HDR zebra highlighting allows
users to verify the location and the size of the specular highlights.
NOTE. The Specular Gamut Error selection is only displayed on the Picture
Brightup menu when option PROD is installed.
HDR Specular Full On. For this setting, the highlight overlay is turned on
for HDR Full settings and produces HDR zebra highlights in the picture for
large areas of the trace that exceeding 100 Nits.
