Configuring Sources for Dolby E Audio Metadata
To configure sources for Dolby E audio metadata
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 Dolby E selection.
Target Type your organization’s reference dialnorm value in the box, or set
it using the slider. The default value is -27 dB, on a scale of -60 dB to
0 dB. This value can then be compared against the measured
loudness, and against the encoded dialnorm found in the VANC
audio metadata (SMPTE ST 2020-A).
Max. lower
deviation The Max. lower deviation parameter determines the tolerated
excursion range below the reference value. The measured levels and
the encoded dialnorm can be compared against each other and
against your organization's target, and alarms triggered in case of
too much deviation. The default value is -5.4 dB, on a scale of -64 dB
to 0 dB.
Note: Setting this parameter to its lowest value (-64 dB) will
prevent the Loudness/Target alarm from being triggered when
silence is detected.
Max. upper
deviation The Max. upper deviation parameter determines the tolerated
excursion range above the reference value. The measured levels and
the encoded dialnorm can be compared against each other and
against your organization's target, and alarms triggered in case of
too much deviation.The default value is 2.4 dB, on a scale of 0 dB to
15 dB.
Note: This section applies to the Kaleido-X and Kaleido-X16 multiviewer
models only.
