NEXIS VW44BVIDEO WALL EDGE BLENDING PROCESSORNEXIS Video Wall Edge blending processor is a curved screen edge blending processor with the ability to provide multiple processing modules to control from 1 to 4 projectors based on user’s requirements. Can provide single processing module for one projector, VW22B for 2 projectors, VW33B for 3 projectors and VW44B for 4 projectors. It was designed for sophisticated edge blending as well as image warping, stacking, projection mapping, irregular video wall and passive 3D…etc. One VW44B can execute 4 projector edge blending without any additional equipment or splitter. Two VW44B can control up to 8 projectors.Each processing module has 3 input ports to support 5 input formats and one HDMI output port. One 4K HDMI loop out port is for raw signal daisy chain connection. Input ports support up to 3840x1080 @60Hz and 4k UHD @30Hz resolution with 4:4:4 full color sampling. It is integrated with 10-bit high end processor, motion adaptive de-interlace and 3:2/2:2 pull-down.PIP (picture in picture) and POP (side by side) are standard functions in each processing module. In one VW44B, user can display up to 8 different input contents on the screen. If user requires PIP or POP image across entire screen, user can use the first module as PIP/POP processor and connect the output to other processing module input port to get PIP/POP image across entire screen.Advanced warp technology is embedded in NEXIS Video Wall Edge blending processor. User can use front panel keypad, IR controller or PC to perform edge blending and sophisticated geometry alignment up to 17x17 grids through user friendly operation interface. Geometry adjustment range is big enough for most of the applications. By remote controller, user can adjust corner position up to H=+_600 pixels and V=+_400 pixels in full HD output resolution. If PC tool is used, geometry alignment range will be double. .It can perform color and white balance adjustment in individual projector. Edge blending region gamma correction and non-edge blending area black level uplift are also standard function in NEXIS Video Wall Edge blending processor.HDMI loop out supports daisy chain connection up to 3840x1080 @60Hz or 4k/2k @30Hz and allows large display with multiple NEXIS Video Wall Edge blending processor cascaded without video distributor. Video wall function in NEXIS Video Wall Edge blending processor is to crop and allocate source image for each projector. Complete curved edge blending can be achieved without PC, video distributor and splitter.NEXIS Video Wall Edge blending processor is an ideal solution for simulation. It can connect with inputs from multiple PC and combine them into one seamless image. It also provides flexible displays in edge blending system. For a 3x projector edge blending system, user can configure as 1+1+1 independent display, 1+2 (two edge blends) and all-in-one (three edge blends). User can also execute edge blending with projector at portrait position to increase image height. It is a good fit with laser projector without the limitation in installation angle.In order to optimize video performance, NEXIS Video Wall Edge blending processor is designed to support non-VESA standard input timing and allow user to create any EDID timing in the range between 1024x768 and 3840x2160.With NEXIS Video Wall Edge blending processor, users can replace high end projector with low cost projector without lens shift, warp and edge blending. It provides easy configuration, low entry barrier, cost effective, reliable and flexible solution.
APPLICATION CASE STUDY
