Calibrating the Kaleido-X
A Kaleido-X system includes a number of cards or modules that process a variety of signal
types. This section explains how to calibrate features related with the different signal types.
Key Concepts
Profiles
IMPORTANT
Calibration changes are applied immediately
Unlike other elements in a multiviewer configuration, system calibrations do
not need to be saved.
• When using XEdit in online mode, calibration changes become
immediately effective.
• When using XEdit in offline mode, calibration changes are applied to the
system representation in your local workspace.
Calibration changes are synchronized
When you export a database to a multiviewer, the latest calibrations prevail
(i.e., if the database you export is from a backup that included earlier
calibration changes, or if calibrations were changed by using XEdit in offline
mode, then any calibrations that were also changed in the meantime on the
multiviewer itself, by using XEdit in online mode, will remain effective after
the export).
Profile With the current version of the Kaleido-X software, profiles are available
for Kaleido-IP multiviewers only. A profile is a group of calibrations that
you configure for a specific purpose, and then apply to specific
elementary streams as needed. A default audio profile, a default video
profile, a default teletext profile, and a default SCTE 35 profile are
available with set calibrations. You may add custom profiles to your
system, and configure them as needed. See
Managing Calibration
Profiles on page 128.
Video profile Video profiles include video input calibrations: alarm debouncing,
metadata holding time, and presence timeout parameters.
Audio profile Audio profiles include audio input calibrations: a zero VU reference level
calibration, alarm threshold calibrations, alarm debouncing, and
loudness calibrations.
