User’s Manual
Router Output Calibrations
• Based on recent standards (EBU R128, ATSC A/85, ARIB TR-B32) and
provide two measures (short term, and momentary) per audio
program. This applies to Kaleido-IP, Kaleido-X16, and Kaleido-X with
second-generation input cards (KXI-16SV rev. 600 and later, KXI-16HS3,
and KXI-16HSV3). See
Calibrating Loudness Measurement on
page 138.
• The Kaleido-IP supports loudness probing of audio streams with a
sampling rate of 48 kHz only.
• For the Kaleido-X and Kaleido-X16, although two audio programs
can be defined per video input, there is a limitation on the number of
concurrent measurements that can be made. See
Calibrating
Loudness Probe Assignments on page 140.
Dolby E selection In the case of the Kaleido-X, and Kaleido-X16 multiviewers, Dolby E
audio can be decoded from two of eight AES pairs within a signal’s
embedded audio stream. The Dolby E selection parameters determine
which AES pairs will be used. See
Configuring Sources for Dolby E Audio
Metadata , on page 143 for details.
Notes
• Dolby E decoding requires the Dolby E option. In the case of a
Kaleido-MX, Kaleido-MX 4K, Kaleido-Modular-X, or Kaleido-X
multiviewer model, one license is needed per input card. See
Enabling
Options on page 491.
• Kaleido-MX, Kaleido-MX 4K, and Kaleido-Modular-X support decoding
of Dolby E metadata from all eight embedded pairs within a video
source.
• Dolby E decoding is not supported on the Audio Bridge Terminal (ABT).
Switch field
selection The switch field parameter determines whether the router module will
perform clean crosspoint changes on the odd (field 1) on the even
(field 2) field, or on any field. See
Calibrating Switch Field Selection on
page 155. Available for Kaleido-X16, Kaleido-X (7RU), and Kaleido-X
(14RU) expansion systems only.
SDI output
reclocking The SDI output reclocking parameter determine whether digital video
signals will have their timing restored at the selected output, to
eliminate jitter. Reclocking is typically used in installations with large
routing devices or long cables in the signal path. See
Calibrating SDI
Signal Reclocking on page 156. Available for Kaleido-X16, Kaleido-X
(7RU), and Kaleido-X (14RU) expansion systems only.
