BBG1003UDXADDA-OM (V1.2)
Framesync
Provides video frame sync/delay offset control and
output control/loss of program video failover selection
controls.
• Framesync Enable/Disable Control
Provides master enable/disable of all framesync functions/controls.
• Lock Mode Select
Selects Frame Sync functions from the choices shown to the left and
described below.
• Lock to Reference: Output video is locked to external reference.
Note: If valid reference is not received, the
indication appears, indicating invalid
frame sync reference error.
• Lock to Input: Uses the program video input video signal as the
reference standard.
Note: If Lock to Input is used for framesync, any timing instability
on the input video will result in corresponding instability on
the output video.
• Free Run: Output video is locked to the device’s internal clock.
Output video is not locked to external reference.
• Output Rate Select
Allows frame rate to be outputted same as input video, or converted to
from the choices shown to the left and described below.
• Auto – output video frame rate tracks with input video.
• 23.98/29.97/59.94 – forces standard North American frame rates.
Can be used to convert 24/30/60 Hz camera frame rates to
corresponding 23.98/29.97/59.94 standard North American frame
rates.
• 24/30/60 – forces 24/30/60 frame rates. Can be used to convert
23.98/29.97/59.94 Hz frame rates to corresponding 24/30/60 Hz
frame rates.
• Initial Startup Format Select
Selects a synthesized frame sync format/rate to be invoked (from the
choices shown to the left) in the time preceding stable lock to external
reference.
Set this control to that of the intended external reference to help ensure
smoothest frame sync locking. This control also sets the device test
pattern format where the device’s initial output at power-up is the internal
pattern instead of program video.
