Selecting the Reference
The FRS-1002 card provides four methods for referencing the incoming
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 FRS-1002 accepts tri-level, bi-level and black burst reference signals.
The video inputs can be synchronized with the house sync signal.
The FRS-1002 card synchronizes the video input 1 and the video input 2
with the same reference signal. Therefore, it is mandatory for input 1 and
input 2 to be of the same video format.
Reference Selection
The Reference Selection function allows the user to select from 4
possible synchronization signals.
Select from:
Internal Ch1: Extracts the reference from the channel 1 (input 1) video
signal. With this selection, the FRS-1002 card needs a valid video signal
at input 1 to properly synchronize. If you are only connecting one video
signal to the FRS-1002 card’s rear module, use input 1.
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.
External 2 (Frame Ref 2): Uses the reference signal from the openGear
frame’s REF 2 input.
