BBG-1040-ACO Function Menu List and Descriptions
Provides video frame sync/delay offset control and
output control/loss of program video failover selection
controls.
Provides master enable/disable of all framesync functions/controls.
Selects Frame Sync functions from the choices shown to the left and
described below.
• Lock to Reference: Output video is locked to external reference
received on the device REF LOOP input.
Note: If valid reference is not received, the
status portion of DashBoard™, 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.
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.
Selects a 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 test pattern
format where the device's initial output at power-up is the internal pattern
instead of program video.
