• Program Video Output Mode Select Provides a convenient location to select between card program video
output and other technical outputs from the choices shown to the left and
described below.
• Input Video – card outputs input program video (or loss of signal
choices described below).
• Flat Field – card outputs flat field.
• Freeze – card outputs last frame having valid SAV and EAV codes.
• Format on Startup Select
Selects a frame sync format/rate to be invoked in the time preceding
stable lock to external reference.
Setting this control to that of the intended external reference helps ensure
smoothest frame sync locking. This control also sets the card format
where the card’s initial output at power-up is the internally generated flat
field instead of program video.
• Format on Loss of Input Select
Selects a frame sync format/rate to be invoked in case of loss of input
video.
Set this control to that of the input video (which can be done by setting to
Maintain Last Format), or set to other alternate format as desired. This
control also sets the card freeze or flat field format in cases of LOS.
• Loss of Input Signal Mode Select In the event of program input video Loss of Signal (LOS), determines
action to be taken as follows:
• Disable Outputs: Disable program video SDI output.
• Flat Field – go to flat field on program video output.
• Freeze – go to last frame having valid SAV and EAV codes on
program video output.
