outputs simultaneously

4 VP-747 - Overview
•Dual scalers—for “live” seamless transitions from one source to another—
with two independent outputs: a PREVIEW OUT and a PROGRAM OUT
(see Section 7.2
The PREVIEW output—including an OSD menu for making adjustments—is for
determining how the scaled output looks before displaying live during a presentation, as
well as for setting the special effects that harmonize the transition when changing
between sources.
Both outputs have separate sets of connectors for DVI/HDMI, VGA (a 15-pin HD
computer graphics video connector), and RGBHV/YPbPr (on BNC connectors)
).
•Eight PREVIEW input buttons for switching a selected input to the PREVIEW
output and eight PROGRAM input buttons for switching a selected input to
the PROGRAM output

Follow mode. When pressing the TAKE button in the Swap mode, the
preview and program inputs switch positions; when pressing in the Follow
mode, the program input follows the preview input
•Scaling and zooming (to up to 400% of the original size)
•High quality de-interlacing 3:2/2:2 pull down
•The frame-rate of a converted movie (24 frames per second) to video
frequencies (25 frames per second (PAL); 30 frames per second (NTSC)
•K-IIT XL™ Picture-in-Picture Image Insertion Technology with ultra stable
picture-in-picture, picture-and-picture, and split screen capability for both the
PREVIEW and the PROGRAM outputs. Any video source can be inserted
into or positioned next to a computer graphics video source or vice versa
