DSK function (CG / LUMA KEY)
The SE-2800 has two Down Stream Keyers (
DSK1, DSK2
). This means it is able to take a key source video input and
replace the white or black parts of this image with the video from another source. If the input video carries an alpha
channel it is also possible to key in this way too.
DSK Settings
Before trying to activate the DSK function it is best to understand how to set up or choose the right options for your
production well in advance of the production.
Press the
ENTER Key
in the
MENU
area of the SE-2800 keyboard. Navigate to the
DSK Settings
option using the
down arrow key. The DSK menu options provided here are:
DSK Settings

Luma Key mode
Luma Key Level

DSK Preset and DSK Program
When looking at the top right corner of the SE-2800 Control Panel / Keyboard
there are four DSK keys. These are labelled Program and Preset.
The upper DSK1 and DSK2 keys relate to activating Down Stream Keying on
the Program outputs.
The lower DSK1 and DSK2 keys relate to activating Down Stream Keying on
the Multi-view or Preview outputs.
Assigning an input to a DSK channel for keying
Using the lower DSK1 or DSK2 buttons you can assign a selected video input to
the chosen DSK video layer.
1. First press and hold down the required DSK button on the lower row. The
Preset row of input sources will light.
2. While still holding down the DSK button, press to select the required input
from the Preset row.
3. The input will flash to confirm it is selected.
This selection will also be confirmed on the HDMI Multi-view, with a T1 or T2
label shown next to the selected input image.
