will affect the Chroma or Luma Keying, so it may be necessary to re-adjust your keying
settings if you have changed the colour processor settings of a channel.
If the Colour Processor button LED is not lit any adjustments will be applied to the
Background (BG) video image
Select the parameter that you want to alter (Colour Saturation, Brightness, Contrast,
Tint (Tint is only necessary for NTSC)) by pressing the relevant button. The button of
the selected parameter will be illuminated red.
N.B. The colour processor adjustments will not function if you are holding a
freeze frame.
Use the Adjustment Knob to set the level you require. You will see the effect on the
output monitor. Once you are happy with the setting you can choose another
parameter and set it in the same way.
If you need to reset any of the parameters to factory default, simply push the
adjustment knob in; after a second the parameter will reset to factory default.
Still – Freeze Frame
The DVK-200 has a still image grab feature that enables you to grab a freeze frame image on both the
Foreground (GREEN or BLUE) and Background video channels.
To grab a still image first press the Colour Processor button.
If the Red LED is illuminated the Foreground (GREEN or BLUE, whichever is active) will
become a freeze frame, if the LED is not lit the Background Video channel will become
a freeze frame.
To grab the freeze frame image press the Still button. The Still button will be illuminated
red, it will remain red while the freeze frame is being held. You will see the Foreground
or Background image freeze on the output monitor.
N.B. The colour processor adjustments will not function if you are holding a
freeze frame.
To release the freeze frame and return to running video, press the Still button again –
the LED should go out.
GPI Control
The DVK-200 has a GPI In and Out port. The GPI In will allow remote switching between the GREEN and
BLUE Inputs. This feature works well with the Datavideo CKL-200 LED light ring. The GPI In Socket is based
on a 3.5mm jack socket. If you wish to make your own GPI solution wire a cable as follows:
If the switch is closed the DVK-200 will switch to BLUE, if the switch is open it will switch to GREEN.
The GPI Out Socket will replicate the GPI In socket, like a loop through. You could use this to control a
second device simultaneously; or maybe to remotely monitor which channel is active (GREEN or BLUE)
The GPI Out will also switch when the GREEN or BLUE buttons are pressed, GREEN is open circuit, BLUE
is closed circuit. It could be possible to also use the GPI Out to start / stop a device each time you switch
from GREEN to BLUE, or possibly switch devices.
