Genlock Tab Screen
Genlock
The Genlock tab offers the following options:
• Auto – use Ref if present, then Input signal if valid, then free-run
• Free-run – no reference lock
• Ref In – Lock to the Video Reference input
• HDMI – Lock to the DVI/HDMI Input (if valid video rate)
NOTE:
Currently, ROI can only lock to HDMI formats that have a SMPTE raster and frame rate and are
within 50 ppm of the SDI output format.
NOTE:
The actual resultant Genlock status is reported to the right of the selection menu.
H- and V-Delay
The controls let you adjust H and V delay from the sync input, by dragging the slider or
entering values in the windows on the right. Horizontal delay is entered in pixels, while
Vertical delay is entered in lines.
NOTE:
H and V delay adjustments are only available when the SDI Out Format is compatible with the
current sync input reference.
