EZwindow4K+
4K UHD Video Combiner
The EZwindow4K+ combines multipe video streams to drive a display up to 4096×2400 @ 60 Hz. Video combining includes keying, overlays, and windowing. Window combinations include Quad, Side-by-Side, Top/Bottom, PIP or your custom window configuration.
Features
Supports 4K displays
Video combining for 4K displays up to 4096×2400 @ 60Hz resolution.
Up to 4 input channels
(2) UHD DisplayPort or HDMI inputs are standard. Optional input mezzanines support up to 2 more inputs, including DisplayPort or HDMI (up to UHD) and several 1080P input types (RGB, DVI, SDI, etc).
Video keying with blending
RGB, Luma, or HSV Keying inside user-defined key area with programmable foreground & background alphas for key = TRUE and key = FALSE. Separate user-defined foreground and background alphas outside the key area.
Video combining
Windowing, side-by-side, top-bottom, PIP, Quad, and more.
Applications
Training and simulation environments
Combines multiple 4K sensor feeds into one fused image; Combines multiple video feeds into one high resolution output for Wide Area Displays; Combines multiple display images into a single instructor operator station (IOS) monitor feed in training and simulation environments.
Combining HUD and out-the-window video
Combining HUD image with Out-the-Window video for a single projector.
Medical environments
Combines a sensor or camera input with PC-Generated text and symbol overlay; Combines multiple modalities.
Real-time, minimal latency video combining applications
Any application that combines multiple video sources in real-time, with minimal latency and minimal video artifacts.
Display Interfaces and Control
Standard I/O
2 inputs / 1 Output Each is selectable between:
DisplayPort 1.2 up to 4K/60Hz or
HDMI 2.0 up to 4K/60Hz.
Optional Inputs
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: 3G-SDI up to 1080P
Type D: DisplayPort 1.2 up to 4K/60Hz or HDMI 2.0 up to 4K/60Hz
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.
Powerful Configuration Utility
Use Westar’s EZwindow4K+ 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
Implement a (3) display instructor monitor
In this example, a EZwindow4K+/AA implements a (3) Display Instructor monitor, where the top window is a wide-area display, and the (2) lower windows are multi-function displays. The EZwindow4K+ captures the dedicated display feeds and places them in an appropriate location on the 4K monitor. A seperate image generator creates the display multi-function buttons for the 2 lower displays.
Combine standard resolution HUD overlay into a 4K video stream using RGB keying
In this example, an EZwindow4K+ fuses a standard resolution HUD image (1920×1200 or less) into a 4K 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.
