Video Pattern Generator 2238 User’s Manual
2-36
HDR ENABLE: It sets if executing the HDR function that is to output the HDR InfoFrame
and Metadata. It is the same as general SDR pattern if the HDR pattern is disabled.
HDR INFOFRAME: It sets if displaying the HDR InfoFrame in the test pattern. (If the
HDR Enable is ON and the HDR InfoFrame is OFF, the HDR InfoFrame and Metadata
will still be sent except the frame is not displayed in the test pattern.)
HDR INFO AUTO: It sets if automatically outputting the HDR parameters based on the
TIMING settings.
ex: If this item is enabled, the MAX_CLL , MIN_FALL and POINT RGBW will follow the
output content and color space to do the setting. It can manually input the desired
parameters if disabled.
HDR EOTF: It sets to EOTF.
00: Traditional gamma - SDR Luminance Range
01: Traditional gamma - HDR Luminance Range
02: SMPTE ST 2084
MAX_DISP_LUM: It sets the maximum display luminance (nits) of the HDR IC under
testing. The range is 0- 65535; 1/Step.
MIN_DISP_LUM: It sets the minimum display luminance (nits) of the HDR IC under
testing. The range is 0- 65535; 1/Step.
MAX_CLL: It sets the Maximum Content Light Level as the brightest point in the pattern.
The range is 0- 65535; 1/Step.
MIN_FALL: It sets the Maximum Frame-average Light Level as the maximum average
brightness point in the pattern. The range is 0- 65535; 1/Step.
POINT R_X: It sets color space chromaticity coordinates - R (X value), range 0.001-1;
0.001 / Step.
POINT R_Y: It sets color space chromaticity coordinates - R (Y value), range 0.001-1;
0.001 / Step.
POINT G_X: It sets color space chromaticity coordinates - G (X value), range 0.001-1;
0.001 / Step.
POINT G_Y: It sets color space chromaticity coordinates - G (Y value), range 0.001-1;
0.001 / Step.
