* 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-C###M2 would be applicable for DP 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. *Regional Windowing is an optional feature
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.
Recommended windowing mode: Independent Windowing (IW)
