(continued)
With framesync enabled, provides the following controls for offsetting the
output video from the reference:
• Vertical (Lines) – sets vertical delay (in number of lines of output
video) between the output video and the frame sync reference.
(Positive values provide delay; negative values provide advance)
(Range is -1124 thru 1124 lines; null = 0 lines.)
• Horizontal (µs) – sets horizontal delay (in µs of output video) between
the output video and the frame sync reference. (Positive values provide
delay; negative values provide advance)
(Range is -64 thru 64 µsec; null = 0.000 µsec.)
Note: Offset advance is accomplished by hold-off of the
reference-directed release of the frame, thereby effectively
advancing the program video relative to the reference.
When Framesync is enabled, specifies the smallest amount of latency
delay (frames held in buffer) allowed by the frame sync. The frame sync
will not output a frame unless the specified number of frames are
captured in the buffer. The operational latency of the frame sync is
always between the specified minimum latency and minimum
latency plus one frame (not one field).
Note: Due to device memory limits, the maximum available Minimum
Latency Frames is related to the output video format selected.
When using this control, be sure to check the Report Delay
display to make certain desired amount of frames are delayed.
Displays the current input-to-output video delay (in msec units) as well as
in terms of Frames/fractional frame (in number of lines).
Status display shows total input-to-output video delay, along
with any framesync delay.
Displays the current framesync status and reference source.
