IP input settings. The following settings are the same for ST2022-6, ASPEN,
and ST2110 (Preview). The Gamma and Color Gamut settings define the
characteristics of the video signal.
1. Choose the appropriate Gamma selection from the drop-down menu. The
selection characterizes the video signal on each virtual input.
SDR Narrow. The reference OETF (Optical to Electrical Transfer
Function) is defined in ITU-R BT.709 with gamma of 0.45 and the
reference EOTF (Electrical to Optical Transfer Function) is defined in
ITU-R BT.1886 with gamma of 2.4.
The scaling places the extrema of the nonlinear color value from zero to
unity at code words 40h(64) and 3ACh(940) in a 10-bit representation.
PQ Narrow. The reference OETF with a high luminance range capability
of 0 to 10,000 cd/m2 standardized in SMPTE2084. The EOTF is the
inverse of OETF.
The scaling places the extrema of the nonlinear color value from zero to
unity at code words 40h(64) and 3ACh(940) in a 10-bit representation.
HLG. The reference OETF is standardized in ARIB B67 and the reference
EOTF is standardized in ITU BT.2100 at the nominal display peak
luminance of 1000 nits.
S-Log2. The reference OETF is defined as Sony S-Log2. The EOTF is
the inverse of OETF.
S-Log3. The reference OETF is defined as Sony S-Log3. The EOTF is
the inverse of OETF.
2. Select the color space of the video signal using the Color Gamut drop-down
menu.
Rec. 709. Standard for HD.
Rec. 2020. Standard for 4K.
NOTE. Rec. 601 gamut is automatically selected when the SD format is detected /
selected in the video signal.
