Black Timing Settings
Use these settings to adjust the timing offset of the selected Black output
relative to the internal reference signal. The range of the timing adjustment
depends on the format of the selected Black output .
Vertical Delay Enter the Vertical Delay in 1 - line increments for the selected Black output.
Horizontal Delay
Enter the Horizontal Delay in increments based on the format of the selected
Black output.
Note : If you are using the 50, 59.94 or 60 Hz progressive sync as a genlock
source and LTC as a time - code source, there are two possible alignments for
the resulting system. Alignment can be checked by looking at the LTC timing
status screen. If the timing is near zero, then it is aligned. If the timing is near a
frame of offset, then it is not aligned.
You must unlock and relock the reference to obtain the needed alignment if
this is important to the application you are using. Alternatively, you can use a
lower frame rate video reference like NTSC, PAL, or 1080i tri - level.
Table 7 shows the Vertical Delay line settings and Horizontal Delay adjustment
ranges.
