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

• Two transition modes (accessible via the OSD): the Swap mode and the

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

with window positioning and sizing controls

• Saving of all settings in non-volatile memory in the unit

• Support for firmware upgrade via USB

• A sophisticated front panel lockout (see

Section 7.5

• A Take button for executing preview to program switching (with transition

effects, which include cuts, fades, and wipes The direction of the wipe may

be selected by the user. The speed of each transition can be adjusted)

)

• ProcAmp controls for both outputs (processing amplification enables

adjustment of different video and audio signal parameters)

• Multi-standard video support: PAL, SECAM, and NTSC (3.58/4.43)
