Using the Downstream Keyer (DSK)
1.
Choose the background picture.
Use the three BACKGROUND buttons to choose the background video. If you want to use the results of the A/B mix as 
the background, press the [A/B MIX] button to make it light up. If you want to use source video directly from channel 6 
or channel 7 as the background, choose [6] or [7/PC1].

2.
Choose the foreground picture.
Use the three FOREGROUND buttons to choose the video you want to composite and display on the foreground. If you 
want to composite a logo, text, or other such element from a computer, press either the [7/PC1] button or the [8/PC2] 
button to make it light up. The picture you selected using FOREGROUND is output to the preview monitor via the PGM 
PVW connector.
Before you perform composition, check whether the picture from the computer is being output correctly to the LVS-800. Send the output 
from channels 7 or 8 to a monitor or projector, and check the picture. The output might not look correct if the proper settings have not 
been made on the computer.

3.
Decide how the keyed material appears and disappears.
Decide how the picture you selected in step 2 to appears and disappears. Select either [CUT] or [MIX]. Selecting [CUT] 
makes the foreground picture appear and disappear instantly. Selecting [MIX] makes it fade in and fade out. You can set 
the time for the fade-in and fade-out (from 0 to 4 seconds) by turning the [TIME] dial.
