3.4.11 The Reference panel
NOTE: The OPT-FS option must be purchased in order to
enable this panel. Otherwise the reference is always taken
from the input signal.
The IRD-3811 output signals should always be genlocked to
some reference source. The genlock source is selected in
the Reference control panel. Use the radio buttons in the
Reference Source area to select from the following options:
•
Auto – this mode selects the first source detected in this
order of priority:
o
External
o
URS
o
Selected Input signal
•
External – selects the signal connected to the rear-panel
REF IN connector
•
525 from URS (Universal Reference Signal) – selects the
internal reference (525) from the backplane
•
625 from URS (Universal Reference Signal) – selects the
internal reference (625) from the backplane
•
Input – uses the currently-selected input signal.
The
Used Reference
box shows the reference currently in
use, which is helpful in Auto mode
Vertical (lines)
With this adjustment, a value ranging from
0
to
+200
lines, compared to the reference or the processing delay, may
be set. This adjustment can be used in conjunction with the horizontal timing adjustment.
Horizontal (
µ
sec)
With this adjustment, a value ranging from zero to the equivalent of 1 horizontal line in the current operating format
(e.g. ranging from
0
to
63.46
µs for 525-line operation;
0
to
64.00
µs for 625-line operation; etc) compared to the
reference or the frame boundary, may be set.
Additional Frame Delay
Use the pulldown to select an extra frame delay to be added to the output.
•
Choices: 0, 1, 2 or 3 frames
NOTE: if the output format is interlaced, only 1 frame can be added. In progressive 720p, up to 3 frames are allowed.
