GeoBox G-700 Quad CH edge blend processor
GeoBox G-700 is high end edge blending processor to control up to 4 projectors in one box. It can be cascaded with multiple box to perfom large scale edge blending system. PIP/POP and image flip and rotation is standard function to provide multiple display windows in each box. It can support multiple PC input sources for high end simulation system and edge blending with projector at portrait position. Flexible display is one of the important function to provide discrete content displayed in each projector or shows one content across all projectors.

        GeoBox G-700 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. G-701 can provide single processing module for one projector, G-702 for 2 projectors, G-703 for 3 projectors and G-704 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 G-704 can execute 4 projector edge blending without any additional equipment or splitter. Two G-704 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 G-704, 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 G-700. 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 G-700.

       HDMI loop out supports daisy chain connection up to 3840x1080 @60Hz or 4k/2k @30Hz and allows large display with multiple G-700 cascaded without video distributor. Video wall function in G-700 is to crop and allocate source image for each projector. Complete curved edge blending can be achieved without PC, video distributor and splitter.

       G-700 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, G-700 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 G-700, 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.
