Video Combiner - EZwindow

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.

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.

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

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.

HSV keying

Two video sources are mixed, based on the calculated HSV value of each RGB pixel in one of the video sources.

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

A window is defined within a background region, where the window may exhibit either the foreground or a mix of foreground and background.

Split screen

A portion of the display (top or left) displays one image or a portion of an image, while the other portion (bottom or right) displays the other image, or portion of an image.

EZwindow 121 /221

Do you need interlaced outputs or 2 inputs in a benchtop box or 2 sets of 2 inputs in a 1U rack, consider the EZwindow 121 or the EZwindow 221

EZwindow4K

If you need to work with higher resolution video and displays, the EZwindow4K can handle up to 4K@60Hz

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
