Genlock/AFL
—
•
AFL
(Accu RATE Frame Lock) locks the output vertical refresh rate to be to that
of the applied HDMI input signal.
•
Genlock
locks the output vertical refresh rate to that of an applied reference sync
signal.
NOTE:
Genlock and AFL lock the output refresh rate to
similar
reference or input
rates. If the input reference or the vertical refresh rate of the HDMI input signal
do not adhere to SMPTE frequencies, the DSC may not output a signal, or the
image may blink.
To select the genlock or AFL mode, select
Genlock/AFL
from the
Output
submenu,
then press any of the arrow buttons to step through the items. The choices are:
•
Off
— The output runs at the selected output frame rate using an internally
generated clock. This selection is the default.
•
Input AFL
— The output is locked to the vertical sync of the HDMI input signal.
This is valid only if HDMI input frame rate matches that of the DSC scaled output
rate.
•
SDI Genlock
— The genlock input and loop-out are used for sync reference. The
Genlock input supports bi-level and tri-level sync.
SDI Genlock locks the output vertical refresh rate to the applied analog genlock
input on the DSC HD-3G A. In the SDI Genlock mode, the output resolution and
refresh rate of the scaler must be set to exactly match the applied analog genlock
signal to ensure a true genlock to the applied SDI Genlock signal.
If the applied SDI Genlock signal does not exactly match the resolution and
refresh rate of the DSC HD-3G A output resolution, the scaler locks its output
vertical refresh to that of the applied SDI reference (frame lock), which may result
in more jitter and may not work for some interlaced signals.
If no SDI Genlock signal is detected, or if the detected SDI Genlock signal would
result in a greater than 165 MHz pixel clock, the DSC generates a free running
pixel clock.
