Scales the selected sources to DVI, RGBHV and VGA simultaneously. It
switches seamlessly between 2 live sources using the selected special
effects, which include cuts, fades, and wipes
3
Has dual scalers—for “live” seamless transitions from one source to
another—with two independent outputs: a PREVIEW OUT and a
PROGRAM OUT (see section 8.2). The PREVIEW output—including an
OSD menu for making adjustments—is for determining how the scaled
output will look 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
(DVI-D on a DVI-I connector), VGA (an HD15F connector), and RGBHV /
YPbPr (BNC connectors)
Features 8 PREVIEW input buttons for switching a selected input to the
PREVIEW output and 8 PROGRAM input buttons for switching a selected
input to the PROGRAM output
Includes 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
Scales and zooms (to up to 400% of the original size)
Offers high quality de-interlacing 3:2/2:2 pull down

1 Recommended for advanced users only – non-standard settings may not be recognized by the display device
2 Sometimes called YUV, or Y, B-Y, R-Y, or Y, Pb, Pr. The component input type (HDTV or YCbCr) may be set as HD or SD
3 The wipe can be from left to right, right to left, up or down, and the corner wipe can start from any corner. The speed of
each transition can be adjusted
4 Accommodates the frame-rate of a converted movie (24 frames per second) to video frequencies (25 frames per second
(PAL); 30 frames per second (NTSC)
