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.
The complete widescreen system consists of the BlendPRO-II, up to four ScreenPRO-II seamless switchers, and the ScreenPRO-II controller. The ScreenPRO-II accepts up to eight (8) universal analog inputs and two DVI signals that can be utilized as unscaled background sources or DSK (Down-Stream-Key). ScreenPRO-II HD also accepts HDSDI signals for scaling. A MatrixPRO router connected in front of the ScreenPRO-II increases the input source capability of the system to 16.
Applications
BlendPRO-II allows easy transition from presentations involving independent screens to multiple projector wide-screen presentations. Input source selection, seamless switching, and image processing control functions are performed by multiple ScreenPRO-II units. The outputs from the ScreenPRO-IIs are fed to a BlendPRO-II which creates data overlap and edge feathering completely transparent to the operator. Test patterns are provided to support projector alignment.

Used Video Processors and Mixers
A video processor, sometimes called a vision mixer, is used for professional compositing of video sources or the selection of video sources, in a similar fashion to the way audio streams are mixed and matched with a mixing console.
This video processor technology is normally used in TV studios, video editing bays and production trucks or studios, in the production of TV shows, theatrical shows and concerts. Video processor is actually a term more commonly used in the United States â?? in Europe and other English speaking countries, the terms video or vision mixer are preferred. The operator of a video processor will generally be called a technical director in all countries however.
The technical director will use the video processor to generate multiple transitions of video sources, such as pattern swipes or dissolves. The video processor can also be used to create color signals (or mattes) and carry out keying operations. As such, most video processors are geared towards professional use, and feature either a Serial Digital Interface (in the case of digital models) or component video connections (in the case of analog models).
A digital video processor is normally used for linear video editing in live TV, in conjunction with video servers and video tape recordings. For other uses, such as video presentations, VJing and small productions involving the use of multiple cameras, an analog video processor is still fairly common.
