Standalone ultra high definition 4K video combiner - EZwindow4KE front view

EZwindow4KE 
4K UHD Video Combiner

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.

Input Board Options* (Channels 1 - 4)

Type A: Multi-Format

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.

Type C: DisplayPort

Supports DisplayPort 1.2 resolutions up to WUXGA with pixel rates up to 165MPixels/sec.

Type BB: Dual DVI

Supports a dual DVI input, for resolutions such as 2560×1600 and 2560×1440.

Type DD: DisplayPort

Supports DisplayPort 1.2 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.

Low Latency I/O Options

M2: DisplayPort 1.2 I/O

Supports DisplayPort (up to 600 MPixels/sec) / 4Kx2K @ 60 Hz.

M6: HDMI 2.0 I/O

Supports HDMI (up to 600 MPixels/sec) / 4Kx2K @ 60 Hz.

Video Blending with Keying

Alpha blend

Two video sources are mixed per a user defined ratio. Alpha blending 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.

Independent windowing: 4K @ 60Hz

Examples (not exhaustive) of independent windowing with up to four video feeds (Windows 1-4) and a low latency 4K background channel

Independent windowing: 4K @ 30Hz

Examples (not exhaustive) of independent windowing with up to four video feeds (Windows 1-4) and a low latency 4K background channel

Powerful Configuration Utility

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:

  • Input timing and output timing
  • Video scaling and area-of-interest (AOI)
  • “Key” processing
  • Border colors
  • Image flip (horizontal and vertical) and rotate
  • Digital contrast and brightness adjustments

Example Applications

Combine standard resolution HUD overlay into a HDMI 2.0 video stream using RGB keying

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-A###M2 would be applicable for DP1.2 I/O.

Recommended windowing mode:  Independent Windowing (IW)

Fuse (4) Multi-function display feeds with a high resolution overlay for a part task trainer

In this example, an EZwindow4KE-AAAAM2 fuses (4) Multi-function display feeds with a high resolution overlay for a part task trainer. The overlay is generated in a 4kx2k DisplayPort 1.2 format. The output device is a 4k x 2k DisplayPort 1.2 monitor.

Recommended windowing mode:  Regional Windowing (RW) at 4K @ 60Hz or Independent Windowing (IW) at 4K @ 30Hz

Implement a (4) Multi-Function Display (MFD) solution

In this example, a single EZwindow4KE-CC##M6 implements a (4) Multi-Function Display (MFD) solution.  Each of (4) windows is assigned to a specific MFD. The symbology is created in 4 windows by a COTS image generator. In the background plane, each window’s associated input can be selected independently as sensor 1 or sensor 2.  A window can also be independently selected to show symbology only, by reducing the background window’s (1, 2, 3, and/or 4) gain to 0. To show “sensor only” requires the IG to drive the specific MFD overlay to black.  Westar LCD controllers are used in many simulated MFD’s.  The LCD controller can be individually configured to select the appropriate area of interest from the full 1920×1200 video stream.

Note:  Higher display resolutions than 600×600 are possible.  Please contact Westar for more details.
