BlendPRO – Wide Screen Image Processor
Manual # 26-0206000-00 / Revision A
BlendPRO
TM
Overview
Description
BlendPRO accepts RGB video from up to 4 high-resolution video sources and processes the video for display in
multi-projector widescreen format. Processing includes data doubling to generate overlapped projected regions as
well as edge-feathering of the overlapped images. The amount of data overlap and the edge-feather transfer function
are user-programmable. BlendPRO allows standard high-resolution images generated with applications such as
Microsoft Powerpoint or Macromedia Director to be displayed in a multi-projector widescreen format. Standard multi-
head graphics cards can be utilized for output. The product completely eliminates the need to precondition source
material during the content creation phase. BlendPRO is compatible with all Folsom Research seamless
switcher/scaler products, including ScreenPRO, ScreenPRO PLUS, VFC-2200, VFC-2200DE and controllers
manufactured by Folsom Research.
Typical Operation
BlendPRO allows you to easily transition from presentations involving independent screens to those where multiple
projectors are used to create seamless widescreen presentations. Typical widescreen applications are illustrated in
the BlendPRO connectivity diagrams in Figures 2.2, 2.3, and 2.4. Input source selection, seamless switching, image
processing and operator control functions are performed by a Multi- Screen Presentation System such as
ScreenPRO PLUS. The outputs from the ScreenPRO PLUS system are processed by BlendPRO, which performs
data doubling and edge-feathering on the images to drive multiple projectors. BlendPRO makes data overlap and
edge-feathering functions completely transparent to the operator. Test patterns are provided to support projector
alignment. BlendPRO simplifies the entire process of preparing for a widescreen event including content generation,
set-up, and real-time control.
