In this application, the DVI-Ramp
2
extracts two windows from the DVI source(s): a FILL window and a KEY
window (window-A is the FILL while window-B is the KEY). The FILL window is converted to an SD/HD SDI
"Foreground" output. The KEY window is converted to an SD/HD SDI "Alpha" output. These outputs with an
appropriate background signal can be fed to a downstream keyer.
For a clean presentation, the DVI-Ramp
2
and the computer’s graphic card should be locked on the same
reference signal to achieve the highest quality.
For this application, the DVI-Ramp
2
can be controlled by software available at
www.miranda.com
or by using
third party software.
