Output Menu
This menu controls features relating to the output video.
OmniTek XR can display a crosshair on the output. The crosshair is always centred over
the sample currently displayed in the dataview. The crosshair can appear on the
analogue (monitoring) output, or the serial digital output, or on both outputs.
XR can detect when the incoming video is out of range, based on the range thresholds
set up in the Engineering menu (see page 20 for details), and key out any erroneous
pixels and replace them with a flashing black and white pattern. This error display can be
included on the analogue output, the digital output, or both outputs. The menu selection
determines which output is used to display the flashing pattern. Note that range errors
can also be highlighted onto the YUV waveforms. The same thresholds are used to
determine out of range, but the choice of highlighting is set on the Options/Data menu,
from within the waveform window.
Similarly, XR can detect when the incoming video (YUV data) is outside of valid RGB
colour space. Again out of gamut pixels can be highlighted on either output with the
flashing pattern. In the same way, out of gamut pixels can also be shown on the RGB
waveforms. Note it is not possible to highlight pixels with range errors and pixels with
gamut errors simultaneously on the waveforms, as pixels with range errors can only be
seen when displaying YUV waveforms, and pixels with gamut errors can only be seen
when displaying RGB waveforms.
