Calibrating the Kaleido-X
Multiviewer Input Calibrations
4 In the Properties pane, set the reference levels to the appropriate values (in dBFS, and
in dBu), using the Zero VU sliders, under Calibration. Alternatively, type the values
directly in the Zero VU boxes.
Calibrating Aspect Ratio Decoding
Aspect ratio information can be encoded following different standards: AFD 2016, AFD VI,
or WSS. The following table shows the different standards and their availability according to
the signal type:
AFD VI information can be encoded as 4 bits or 3 bits (legacy).
To select the AFD source for an SD signal
1 In the main window, click the System tab, and then click Description/Calibrations on
the second-level tab bar.
A hierarchical list representing the current system appears.
2 In the list, expand the multiviewer whose inputs you wish to calibrate.
3 Expand the appropriate input, and then click AFD & WSS.
Note: This section applies to multiviewers that are used to monitor
SD signals. In the case of HD signals, since the AFD information always
follows AFD 2016, no calibration is needed. No calibration is needed for the
Kaleido-IP either, since it supports decoding of a signal’s aspect ratio from
AFD metadata only. See
page 125 for more information.
