6. SD / HD Video Generator Settings
The nanosyncs HD generates one SD video sync standard and one
HD tri level standard simultaneously.
You can set the frame rates and formats independent for the SD and
HD generator section.
Both standards are always frequency locked to the selected video
reference, also when the frame rates are different.
When using the same frame rate (or double/ half rates) the standards
will also be phase locked together (phase locked means both v-sync
patterns start exactly at the same position).
Enter the setup mode and select the SD STD. section.
Press the SELECT button to set the SD generator to NTSC, PAL 25
or PAL 24.
NTSC :
525 lines 29,97 fps, SD used in the US, Japan
PAL 25: 625 lines 25 fps, SD used in Europe …
PAL 24: 625 lines 24 fps, used for film postpro
PAL 23.98: 625 lines 23,98 fps, indicated by LEDs PAL 24
and NTSC simultaneously
Note: the generated PAL 24 signals do not insert a colour burst.
Select the HD STD. section to edit the generated HD tri level
standard, whereas "x2" indicates double frame rate as on display in
the FPS field (L8):
1080 I/PSF x2:
1080 lines, interlace or progressive
segmented frame
47.95, 48, 50, 59.94, 60 fps rates
Note: For a sync signal there is no difference between both standards.
A progressive segmented frame means progressive scanned picture
contents are transferred within an interlace frame format.

and FPS the hd video outputs are switched off and the FPS LEDs will
extinguish.
