For example, on Roadster and
HD models the Dual SD/HD-
SDI module is factory-installed
at (Option 1). The
INPUT 5
Option 1 Card submenu
provides controls for
configuring the various
connections on this multi-
input, multi-output module. As desired for your application, you can define 1) which
physical input loops through to which output, and 2) which functional input (main or
PIP signal) loops through to which output.
PIP (Picture-in-Picture) and Seamless Switching are independent but related
projector features that both utilize two image-processing paths within the projector.
In the case of Picture-in-Picture, this double processing enables you to display two
different images simultaneously – typically a smaller "secondary" image within a
large "primary" background. In a seamless switch, the double processing essentially
occurs between displays so that a full image relayed from one source can smoothly
transform into a full image from another source. This change can be virtually
instantaneous, or slowed as desired so that the current image appears to dissolve or
"fade" into the new image.
Options for enabling and controlling PIP and Seamless Switching all reside in the
same menu. Note, however, that because both features utilize the projector's double
processing capability, PIP and Seamless Switching cannot be used together. For
example, fading a pair of PIP images into a new display from a different source is not
possible.
For best PIP or Seamless Switching results, use two different signal types* as defined
below. Do not mix two signals of the same type.
Signal Type Description (Input Location)
#1 5 BNCs (RGBHV or YPbPr)
#2 DVI - I (analog or digital)
#3 Decoded signals (Input 3, Input 4, Composite video, S-Video, or any video
signal via Input 1 BNC connectors or via an analog option card).
#4 Analog Option Cards
#5 Digital Option Cards
#6 Digital Option Cards
*
HD interlaced sources are not recommended for the PIP window.
Other PIP or Seamless Switching tips to keep in mind include:
•
When using two digital signals or one analog and one digital, each must be ≤ 165
mega pixels.
•
When using two analog signals, each must be ≤ 90 mega pixels.
•
Avoid using an interlaced source in the PIP window
•
Seamless switching may affect image quality in some cases
