Selecting the Reference
The XVC-1001-DC card provides four sources for referencing the outgoing
video signal. At the bottom of the Card Setup window, the reference
selection can be chosen from a drop down menu. The reference selection
is automatically saved and will be restored after power-up.
The XVC-1001-DC accepts tri-level, bi-level and black burst reference
signals.
Reference Selection
The Reference Selection function allows the user to select from 4
possible synchronization signals.
Select from:
Internal Channel 1: Extracts the reference from the channel 1 (input 1)
video signal. The input 1’s reference signal can be independent from the
house sync signal and be of a different frame rate.
External 1 (Frame Ref 1): The openGear frame has a distributed
frame reference, allowing a single incoming reference sync signal to
feed information to all modules in a frame. External 1 uses the reference
signal from the openGear frame’s REF 1 input. The XVC-1001-DC’s video
input 1 must be genlocked with the openGear’s REF 1 input to use that
selection.
External 2 (Frame Ref 2): External 2 uses the reference signal from the
openGear frame’s REF 2 input. The XVC-1001-DC’s video input 1 must be
genlocked with the openGear’s REF 2 input to use that selection.
