OmniTek OTR 1001 User Guide, v3.1a T-5
Luminance
Works in a similar way to the above Motion specification to set the conditions under which the
OTR will report a luminance error.
Chrominance
Works in a similar way to the above Motion specification to set the conditions under which the
OTR will report a chrominance error.
Average Picture Level (APL)
Defines the maximum acceptable average signal level over the active part of the frame. If the
APL is above this figure, an error will be reported.
Error Checking Section
It is important to ensure that the data ranges specified reflect the type of data you are expecting.
Gamut Range: Error Mask
Sets the number of lines from both the top and bottom of the display, and the number of the
pixels from each edge to be omitted from the error checking process. This is intended to handle
video in which the edges near the sync are corrupted. The mask has no other effect on the data,
which continue to be grabbed, displayed on the waveform views etc, in their entirety.
Gamut Range: YCbCr
Specifies the conditions under which a YCbCr Range Error will be reported.
The first line specifies the percentage of the image which needs to be out of range before an error is
reported. This is followed by the minimum and maximum acceptable values, expressed in the
amplitude measurement units selected on the System page of the Config window (see Section T.4).
The Polarity Outside setting determines whether an error is reported when the value is outside
the specified range (tick box checked) or inside the specified range (tick box clear).
The other two settings control whether the error is flagged on copies of the video that are
mapped to the SDI output ports and/or on the OTR’s own Picture display.
Gamut Range: RGB
Specifies the conditions under which an RGB Range Error will be reported, in a similar way to
the above YCbCr Range Error.
Gamut Range: Composite
The Composite Matrix Type sets whether composite waveform displays are generated using a
composite matrix that is selected automatically (based on the current input video standard) or
generated using the particular composite matrix selected here.
The other settings specify the ‘rules’ to be followed in generating a Composite waveform, in
particular the maximum and minimum values to apply when using the different composite
matrices. The other two settings control whether the error is flagged on copies of the video that
are mapped to the SDI output ports and/or on the OTR’s own Picture display.
Physical
This section is concerned with data embedded in the video signal that may be present/absent or
otherwise in error. In most cases, a value is set which gives the number of such errors that can
happen per frame before an error should be reported. In the case of EDH values, selections can
be made for the number of consecutive frames containing an error in
either the Full frame EDH
value or the Active frame EDH value after which an error is reported (the Full/Active setting), or
for Full frame EDH errors and Active frame EDH errors counted separately.
