Location and Function of Parts and Controls
3
ANALOG I/O block
REF. VIDEO (reference video input) connectors
(BNC type) and 75-ohm termination switch
Connect a composite video signal, such as a black
burst. The two connectors are in the loop-through
condition. When the loop-through output is not used,
set the 75-ohm termination switch to ON.
MONITOR OUT (monitor output) connector
(BNC type)
Outputs the composite video signal for monitoring.
Connect to the composite video inputs of the DLE-
110 system or a monitor.
4
DIGITAL I/O block
PROGRAM OUT 1/2/3/4 (serial digital video/
audio output) connectors
Outputs four channels of the serial video/audio
signals (program signals) to which effects have been
added.
The audio signal is output delaying by one frame
from the audio input signal from the MAIN
connector.
DSK INPUT (down stream key input) connector
(BNC type)
KEY (key source signal input) connector: Inputs
the serial digital video signals. Connect to the
external output connector of the character
generator to input the key source signal of the
down stream key.
FILL (fill signal input) connector: Inputs the serial
digital video signal
Connect to the external video output connector of
the character generator to input the fill signal of
the down stream key. When the key source signal
connected to the KEY connector is not used, the
luminance signal of the fill signal input from this
FILL connector is used as the key source signal.
SDI INPUT (serial digital video/audio input)
connector (BNC type)
SUB (sub serial digital video input) connector:
Inputs the serial digital video signal to be used as
the video signal when the picture-in-picture effect
is added to the signal from the MAIN connector.
Connect to the SDI output connector of the
hybrid recorder. However, the audio signal is not
input to this connector.
MAIN (main serial digital video/audio input):
Inputs the serial digital video/audio signal.
Connect to the SDI output connector of the hybrid
recorder. The signal is processed with the effects
and output from the PROGRAM OUT connectors.
Depending on the switch position of the IF-643 board,
the connector accepts either 525- or 625-component
serial digital signals.
5
Mouse connector (D-sub 9-pin, conforming to
RS-232C standards, male)
Connect a commercially available mouse.
You can control the effect such as the size and position
of the mosaic pattern.
