Any two of the inputs can be selected as processing channels. The FS1 and XD1 can automatically detect
input video formats; error monitoring (EDH) is performed when the input format is SD-SDI. HD-SDI
inputs are monitored by Cyclic Redundancy Checks (CRC). For any input video format that is not
supported by the module, the video signal is treated as an unknown format and the module switches to
LOV
(Loss of Video)
Mode
. You can choose to allow unknown or unstable video to
Pass Through
,
Freeze
,
or be replaced with
Black
.
Auto Routing
The FS1 and XD1 make it possible to select three different video sources in descending order of
preference. In the event that one source fails, the module switches to the "next best" choice. The
options are:
•
EXT Vid 1 (from external SDI 1 In)
•
EXT Vid 2 (from external SDI 2 In)
•
CTR SDI (the currently operating controller)
Using the
Auto Switch Delay
parameter, you can set the amount of delay before the module switches to
the next best video source (default is 2 seconds). If the
Primary Choice
signal returns after the modules
are routed to one of the other inputs, the FS1 and XD1 revert back to the
Primary Choice
signal. (You
must set
Auto Fallback
to
Yes
for this to occur.)
If you want to be able to
manually
return to the
Primary Choice
(instead of allowing it to happen
automatically), leave
Auto Fallback
set to
No,
and then manually return to the primary signal by setting
Force Fallback
to
Yes
.
When
Auto Routing
occurs, the module triggers an
Input Routing Auto Switched
fault.
EDH-CRC-SQM 1 and 2
When enabled, these parameters report EDH/CRC errors. Additional status parameters report low/peak
Y and C levels.
Audio De-Embedding (DMB)
DMB 1
and
DMB 2 Grp x De-embedding Control
parameters provide the ability to either repeat or mute
the last audio sample when the de-embedder encounters an error. Using the
DMB 1 and DMB 2 Grp x
DBN Error Reporting
parameters, you can configure the module so that these errors are either ignored
or trigger a fault.
The status of the audio de-embedders is reported in the
Audio Input Status
block.
