Block diagram of scaling and keying
This unit has 2 scaling engines and 3 keyers. The outputs from the scaling engines and keyers are mixed
together to form a single image.
Lock source Z
As the diagram shows, the two DVI-I inputs are available for use by either of the scalers, or as a lock
source, also known as window Z, where the output is synchronized to an input.
Read more on page 11.
Windows A and B can be scaled, and then each window can be keyed to remove any color, or nearby
range of colors.
Read more on page 20.
The resulting windows are merged together into a single output, according to your chosen layer priority.
Read more on page 14.
Not shown in the block diagram:
nStill image stores SIS1 and SIS2, which provide a static source for windows A or B.
nBorder generators, which can place borders of any color or opacity around each window.
