The EZwindow4KE™ UHD video combiner provides video combining for 4K displays up to 4096×2400 @ 60 Hz. Designed for applications that require combining of low latency UHD video with up to 4 additional video streams, to produce a single UHD video output with overlays and/or windows.
Video combining for 4K displays up to 4096×2400 @ 60Hz resolution
(1) low latency UHD DisplayPort or HDMI input plus (4) input board slots that may house various input boards
RGB, Luma, or HSV Keying inside user-defined key area with programmable foreground & background alphas when key is true or false. Separate user-defined foreground and background alphas outside the key area
Windowing, split screen, top-bottom, PIP, and more
Combining multiple display images into a single instructor operator station (IOS) monitor feed in training and simulation environments
Combining HUD image with Out-the-Window video for a single projector
Combining multiple modalities
Any application that combines multiple video sources in real-time, with minimal latency and minimal video artifacts
Supports the following inputs: DVI-D, RGBHV, RGBsog, RS170, RS343, composite (NTSC/PAL). Any one of these inputs may be selected. Type A supports resolutions up to WUXGA with pixel rates up to 162MHz.
Supports DisplayPort 1.1a resolutions up to WUXGA with pixel rates up to 165MPixels/sec.
Supports a dual DVI input, for resolutions such as 2560×1600 and 2560×1440.
Supports DisplayPort 1.1a resolutions up to 2560×1600 @ 60Hz, and pixel rates up to 330MPixels/sec.
* Type A and C boards can be installed in any one of 4 slots for up to 4 cards per unit. Type BB and DD boards can be installed in slots 1-2 or 3-4 for up to 2 cards per unit.
Supports DisplayPort (up to 600 MPixels/sec) / 4Kx2K @ 60 Hz.
Supports HDMI (up to 600 MPixels/sec) / 4Kx2K @ 60 Hz.
Two video sources are mixed per a user defined ratio. Alpha blending is the most common video blending technique.
Two video sources are mixed, based on RGB content of one of the video sources. Allows Up to (4) different levels of mixing based on If-Then-Else logic statements for RGB content.
Two video sources are mixed, based on the calculated HSV value of each RGB pixel in one of the video sources.

Use Westar’s EZwindow4KE configuration utility to define the input timing, output timing, keying scheme, and the area-of-interest within the source video and where to map the AOI within the output resolution. The remote interface can be used for initial setup or operational control and supports user-defined:
In this example, an EZwindow4KE-A###M6 fuses a standard resolution HUD image (1920×1200 or less) into a HDMI 2.0 video stream. An RGB key with programmable alpha values (separately programmable foreground and background alpha values outside the key area, when Key= TRUE, and when Key = FALSE) results in a realistic HUD overlay. This enables a single projector to be used for both the OTW image and the HUD overlay.
Alternately, a EZwindow4KE-C###M2 would be applicable for DP I/O.
