4.1.3.9 Classifying- Keyer Control

Keyers are a powerful tool that arrange visual elements from different sources on the
same video image. There are two types of keyers available on the switcher, upstream
keyer and downstream keyer, that KEY button is assigned as upstream keyer, while
DSK button is assigned as downstream keyer, as shown in Figure 4.1-43.
In keyer control, multiple layers of video or graphics are stacked on top of the
background video. Altering the transparency of parts of these keyer layers allows the
background layer to be visible. This process is called keying. Take downstream keyer
for example, push DSK on air in next transition, the caption, Logo or other accessory
images keying by DSK control will not disappear with the background exchanging.
The layers relationship from up to down is upstream keyer, downstream keyer and
background source, as shown in Figure 4.1-42:
