• Pattern
• Capture Controls
Sets TSG output pattern (as shown from choices to the left) when TSG is
invoked either automatically of manually.
For User Captured selection, first capture an input video frame as
follows:
Note: • Output video freeze and momentary interruption occurs when
an image is captured. Do not perform this step using live OTA
video.
• HD captures take longer than SD captures to fully acquire
frame.
1. Set Video Output Mode to Input Video.
2. Roll video containing image to be captured.
3. When segment containing desired image appears, set Freeze to
Capture to On.
4. Click/confirm Capture User Pattern: Confirm. Wait until the Progress
bar indicates 100%. Image is now captured.
5. When capture is 100%, set Freeze for Capture to Off; the live input
video resumes.
Note: User captured frame displays properly only when Generator
Output Format setting matches format of captured frame; the
capture function does not cross-convert formats.
• Vertical Delay Control When Reference 1 or Reference 2 framesync is enabled, sets vertical
delay (in number of lines of output video/format) between the output
video and the frame sync reference.
(Range is -1124 thru 1124 lines.)
Note: Lines refer to lines in the output video format, and not to the
reference format.
• Horizontal Delay Control When Reference 1 or Reference 2 framesync is enabled, sets (in µsec of
output video timing) horizontal delay between the output video and the
frame sync reference. (Range is -64.000 thru 64.000 µsec)
Note: When an external framesync reference is used, the card will not
produce a framesync reset until the variance between framesync
reference and output video exceeds ± 2 clock periods. Therefore, a
framesync reset will not result if offsets within this window are
applied. To apply an offset/framesync reset within this window, first
apply a relatively large offset, then apply the target smaller offset.
Example: To apply a 1-period offset, first apply a 10-period positive
offset and then apply a 9-period negative offset. This results in the
target 1-period offset being applied to the output video.
