8 Understanding the VP-727
This section describes the:
UNIVERSAL inputs, see section 8.1
PREVIEW/PROGRAM outputs, see section 8.2
Switching/Scaling of an input, see section 8.3
PIP feature, see section 8.4
Panel Lock, see section 8.5
8.1 Understanding the UNIVERSAL Inputs
The
VP-727
has 8 sets of inputs
1
. Each set can be programmed to operate as
composite video, s-Video, component video, RGB/YUV, RGBS, RGsB, or
RGBHV.
The
VP-727
is a
universal
presentation matrix switcher / scaler: you choose
what type of source to connect to each input. You can connect different video
types or the same or similar video types. See the examples in Figure 3 and
Figure 4 in section 6.
8.2 Understanding the PREVIEW/PROGRAM Outputs
The
VP-727
has 2 outputs: a PREVIEW output, and a PROGRAM output.
Each of these outputs functions independently and has DVI connectors and
VGA connectors, as well as sets of 5 BNC connectors

: R/P

, G/Y, B/P
B
, H
S
,
and V
S
. Using the
PREVIEW
output, you can:
See how the scaled output will look before displaying live during a presentation.
As the example in Figure 8 illustrates, after seeing how the RGB source looks
when scaled to DVI, it can be interchanged with the YUV source, seamlessly,
using an elaborate (in this case chessboard) transition effect
Harmonize transition to the PROGRAM output after determining the look
and feel when in the PREVIEW output
Use the OSD menu to make adjustments and choose the settings
Set the transition, choosing one of any eight special effects
Using the
PROGRAM
output, after pressing the TAKE button, you can see the
transition

.
1 Each set consists of 5 BNC connectors: R/Pr, G/Y/CV, B/Pb/C, Hs/Cs, and Vs
2 Used to output one of the following: RGB, RGBHV, or component video
3 After making some changes in the unit (for example, selecting a new input to the PREVIEW output), the TAKE button will
be turned off (not illuminated) momentarily (until the unit successfully locks to this input). The TAKE button should not be
pressed until it lights up again, otherwise there will be a period of black during the transition
