5.7.2. Reference Monitor
Reference Status:
The
Reference Status
reports the current source of reference for the video path. If the
video path is currently locked to a reference signal, it will report the source of the reference signal as
Card
ref
,
Frame ref 1
, or
Frame ref 2
. If the card is actively locked to input video, it will report
Video
. If the video
path is currently free-running, it will report
None.
Reference Type:
The
Reference Type
reports the type of reference for the video path. If the video path is
currently locked to a reference signal, it will report the type of the reference signal as either
Bi-phase
or
Tri-level.
If the card is actively locked to input video, it will report
Video
. If the video path is currently
free-running, it will report None.
Genlock Standard: External Genlock Standard
reports the video standard of the detected reference
signal. If a signal has been detected, but the module determines the video standard, it will report
Unknown
. If no reference signal is present on the selected reference input, it will report
Not present
.
5.7.3. Auto Reference Fail-over
Auto Reference Fail-over:
The
Auto Reference Fail Over Enable
is used to set a Priority Genlock
sequence. When enabled the module will automatically fail-over to the next priority reference input
selected in the reference priority controls.
Priority Reference Select:
This section allows the user to set the desired first, second and third priority
reference point.
•
To select locking to the incoming video, select Video (none).
•
To select the REF IN BNC, choose External genlock.
•
To select Frame Ref 1 on the 7700FR-G or the 7800FR, choose Frame reference 1
•
To select Frame Ref 2 on the 7700FR-G or the 7800FR, choose Frame reference 2
•
To select No reference input select None
Auto Reference Valid Timeout:
This control sets a user specified time that the reference input return to
the Priority 1 reference when a valid genlock signal is re-asserted.
Auto Reference Invalid Timeout:
This control allows the user to set a timeout length when a reference
signal is lost on the Priority 1 Reference input. Once the module confirms that, the genlock input is no
longer valid.
Auto Reference Status:
The Auto reference Status Monitor is used to see what the current Priority the
module is under. It will report either Priority 1 or Priority 2 and the source of the current genlock input.
Auto Reference Reset Button:
The Reference Reset Button allows the user to reset the
Prioritized
Reference Fail Over
back to original settings.
