Notes
The DME1 input reference signal is common to the
switcher.
In the <Ref Input Format> group of the Engineering Setup
>System >Format menu (7313), select one of the
following.
Tri Sync: Tri-level sync for an HD system
BB (Black Burst): Black burst or sync
The following table shows the relation between signal
format and the frequency of a signal that can be used as the
input reference signal.
Setting Conversion Formats
The format conversion is valid only when [BB] is selected
in the <Ref Input Format> group.
The format conversion is assigned to primary inputs and
outputs in advance.
For details about the assignment,
1 “Selecting the
Primary Input to be Used in the Format Converter”
(p. 348) and
1 “Selecting the Output to be Used as the
Format Converter” (p. 353) .
Format converter
The following video signal conversion formats are
supported by the format converter.
•
Up-conversion: SD (4:3) to HD (16:9)
•
Down-conversion: HD (16:9) to SD (4:3)
•
Cross-conversion: HD (720P) to HD (1080i), or HD
(1080i) to HD (720P)
The number of format converter inputs and outputs can be
set to one of the following in “FC Config”
(
1
p. 322) .
•
8 inputs, no outputs
•
4 inputs, 2 outputs
Notes
After format conversion, input and output signals have
one-frame delays with respect to the reference signals. To
synchronize converted input signals and unconverted input
signals, it is possible to delay the unconverted input signal.
For details,

“To delay unconverted input signals
(frame delay function)” (p. 315) .
Conversion format combinations
The combinations of switcher signal formats and
supported format converter formats are as follows.
