In situations where the accuracy of incoming ST-352 packets cannot be relied upon, the instrument can
be forced to ignore the ST-352 packets, and image parameter overrides can be set by the user. To
ignore incoming ST-352 packets enable ‘Ignore Payload Identifier Packets (ST-352)’ in the submenu.
l Ignore Payload Identifier Packets (ST 352) > [Enabled, Disabled]
Payloads with ignored ST 352 packets are indicated within the ‘Analyzer - Video Standard’ window.
Transfer Curve and Colorimetry Overrides
HDR content may still contain the SMPTE payload ID for SDR and Rec.709 color space (as ‘standard’).
Therefore, when analyzing HDR and WCG (Wide Color Gamut) content, overrides can be enabled for the
appropriate HDR transfer curve and color space:
l Enable Transfer Curve Override > [Enabled, Disabled]
l Transfer Curve Override > [SDR-TV, HLG, PQ, S-Log3]
l Enable Colorimetry Override > [Enabled, Disabled]
l Colorimetry Override > [Rec.709, Rec.2020]
Sub Image Pixel Mapping Format Override
Where sub image format signals are delivered without ST-352 packet payload IDs or with mislabeled sub
image mapping information, e.g. if 2 sample interleave (2-SI) signal content is delivered incorrectly as square
division (SQ), it is necessary to be able to override the erroneous mapping in order to display the content
correctly.
l Enable Sub Image Pixel Mapping Format Override > [Enabled, Disabled]
l Sub Image Pixel Mapping Format Override > [2 Sampl...erleave, Square Division]
Note: The resulting effects of enabled overrides will be reflected in other image analyzer instruments within
the Qx Analyzer instrument toolset.
