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. 243) and 1 “Selecting the Output to be
Used as the Format Converter” (p. 248) .
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. 216) .
• 8 inputs, no outputs
• 4 inputs, 2 outputs
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, 1 “To delay unconverted input signals
(frame delay function)” (p. 213) .
