allows additional frames to be added after/before the frame sync. As an example,
a frame phasing of 4 will produce a delay between 4 and 5 frames.
When there is no reference and the phasing is done on the video, the frame
phasing adjustment adds a delay in frame increments between the input and
output video (
Frame Delay/Frame Buffer
mode). A zero phasing (H & V) is not
possible because of the processing delay of the card.
To adjust frame phasing perform the steps below:
1. Press SELECT to enter the menu.
PROC
is displayed.
2. Depress the “+” push-button until
TIMG
is displayed.
3. Press SELECT to enter the Timing menu.
FRAM
is displayed.
4. Press SELECT to enable the frame phasing menu. The current value is
displayed.
5. Use the “+” or “–“ push-button to set the required frame phasing value. Press
the “+“ and “–“ push-buttons simultaneously to set frame phasing to default.
6. Press SELECT to store the new frame phasing value.
7. Press ESC to return to
TIMG
.
8. To return to normal mode, press ESC.
3.5.2 Vertical Timing Delay
The vertical timing delay adjustment is made in increments of 1 video line up to
524 lines in 525-lines format and 624 lines in 625-lines format. Follow these steps
in order to adjust vertical timing delay:
1. Press SELECT to enter the menu.
PROC
is displayed.
2. Depress the “+” push-button until
TIMG
is displayed.
3. Press SELECT to enter the Timing menu.
FRAM
is displayed. Depress “+”
until
VERT
is displayed.
4. Press SELECT to enable the vertical timing delay menu. The current timing
delay in video lines is displayed.
5. Use the “+” or “–“ push-button to set the required vertical timing delay. Press
the “+“ and “–“ push-buttons simultaneously to set vertical timing delay to 0
video lines.
6. Press SELECT to store the new vertical timing delay.
7. Press ESC to return to
TIMG
.
8. To return to normal mode, press ESC.
3.5.3 Horizontal Timing Delay
The horizontal timing adjustment is made in increments of 37 ns up to a range of
one video line (63.5 µs in 525-lines format and 64.0 µs in 625-lines format).
Follow these steps in order to adjust horizontal timing:
1. Press SELECT to enter the menu.
PROC
is displayed.
2. Press the “+“ push-button until
TIMG
is displayed.
3. Press SELECT to enable the timing menu.
FRAM
is displayed.
4. Press the “+” or “–“ push-button to display
HORZ
.
5. Press SELECT to enable the horizontal timing menu. The current timing delay
in µs is displayed.
6. Use the “+” or “–“ push-button to set the required horizontal timing delay.
Press the “+“ and “–“ push-buttons simultaneously to set the timing to 0 µs.
