EZwindow
Video Combiner
The EZwindow™ video combiner converts analog or digital video from up to 5 inputs into a common, synchronized output, using one of a variety video combining or blending methods. EZwindow™ is designed for minimal latency while providing broad area-of-interest control on inputs and outputs. In addition, EZwindow™ supports video overlays for specialty simulation applications.
The EZwindowHR™ video combiner provides a variety video combining or blending functions for one high resolution (up to 2560×1600 @ 60 Hz) input channel, and from 1 to 5 standard resolution (up to1920x1200 @ 60 Hz) input channels.
Features
Up to 6 input channels
Combine up to 5 standard inputs with the EZwindow or combine up to 6 inputs (5 standard plus 1 low latency) with the EZwindowHR
Video keying with blending
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
Video combining
Windowing, split screen, top-bottom, PIP, and more
Applications
Training and simulation environments
Combining multiple display images into a single instructor operator station (IOS) monitor feed in training and simulation environments

Real-time, minimal latency video combining applications
Any application that combines multiple video sources in real-time, with minimal latency and minimal video artifacts
Introduction to EZwindow
Designed for applications that require multiple video feeds to be windowed or combined into a single output, EZwindow is the perfect solution for training and simulation environments, command and control centers, or real-time video monitoring applications.
Input Features
Up to 5 Standard Resolution Inputs
- DVI-I standard (TMDS and Analog RGB) Inputs
- Digitization of computer-generated video sources with separate sync, composite sync, or sync-on-green

- Fine phase clock adjustment for pixel sampling
1 Additional High Resolution Input (EZwindowHR)

- Accepts RGBHV analog or DVI video at the desired output
- Output timing tied to high-res input if used
Output Features
- DVI-I standard (TMDS and Analog RGB) Outputs
- Resolutions up to 2560×1600 with pixel rates up to 330
MPixels/sec with EZwindowHR. Resolutions up to 1920×1200 with pixel rates up to 166 MPixels/sec with EZwindow - Digital contrast and brightness adjustments on output
Video Combining Capabilities
Alpha blend
Two video sources are mixed per a user defined ratio. This is the most common video blending technique.
RGB keying
HSV keying
Stereo mixing
Two video sources are synchronized, and then output as alternating fields. This is used for creating active stereo outputs from separate left and right sources. The output is synchronized to one of the inputs. 120 Hz operation is possible, at up to 165 MPixel/sec.
Windowing
Split screen
Powerful Configuration Utility
Use Westar’s EZwindow 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 configuration utility supports user-defined:
- Input Timing and Output Timing
- Video Scaling and Area-Of-Interest (AOI)
- “Key” Processing
- Border Colors
- Image Flip (Horizontal and Vertical)
Example Applications
Keying on a video input to combine with 2nd input
In this example, an EZwindow-2 is used to key a live video feed (in the foreground) over the map graphic (in the background). Using HSV keying, the greenish area (as well as the black, non-active area) becomes transparent, thereby passing the background.
Combine three different video feeds with a text overlay using luma keying
In this example, an EZwindow-4 is used to combine 3 different video feeds into the background layer. A 4th input is mapped to the foreground layer, where luma keying is used to overlay the text over the combined imagery.
Combine 3 video inputs using alpha blending and luma keying
In this example, an EZwindow-3 a) maps Input #2 to the background layer as a lower priority, b) uses a synthesized channel to alpha blend Inputs 2 and 3 in a specific area-of-interest within the background layer as a higher priority, and c) overlays Input 1 via a luma key atop the background layer.
Combine 4 video inputs for a high resolution dual DVI monitor
In this example, an EZwindow-4 uses a special high resolution output mode, allowing (4) 1280×800 windows to be combined onto a 2560×1600 Dual DVI monitor.
Combine 4 video feeds and downsize into one feed for a standard monitor
In this example, an EZwindow-4 is used to capture 4 1024×2400 slices of a 4K projector to combine and downsize these feeds to display on a standard 1920×1200 monitor. This is useful while generating content for the 4K projector, as well as for Instructor viewing of the 4K projector feed.
Combine 2 video feeds (left and right) into a alternating line 3D video
The EZwindow-2 is used to combine 4 a left image and a right image in an alternating line 3D image, appropriate for monitors using alternating line 3D optical films and passive 3D glasses.
Combine four different video feeds with a high res input using luma keying
In this example, an EZwindowHR-4 is used to combine 4 different video feeds into the background layer. The HR input is a 2560×1600 video stream mapped to the foreground layer, where luma keying is used to overlay the symbology over the combined imagery.
Synchronize a monochrome video input with a second overlay video input
In this example, a EZwindow-2 synchronizes a monochrome video input with an overlay video input, then allows 3 monochrome outputs, each selectable between the monochrome video, the overlay video, or a combined image of overlay video + the monochrome video
