EZwindow4K-LL Specifications EZwindow4K-LL TM Ultra HD Video Combiner Synchronizes 1 to 4 standard video inputs with a UHD video stream, to produce a UHD video output with overlays and/or windows. EZwindow4K-LL Video Processor The EZwindow4K-LL video combiner provides video combining for 4K displays up to 4096x2400 @ 60 Hz. Up to 4 input cards are used to populate windows in the Scaler Plane Visual. A standard 4 x Single Link (SL) low latency input channel (or an optional low latency mezzanine input) forms a Low Latency Plane Visual. The Scaler Plane and the Low Latency Plane are combined to create the Display Plane Visual. The standard UHD output is 4 x SL. Optional UHD outputs are supported by mezzanine boards. Order Configuration The EZwindow4K-LL has (1) low latency UHD 4xSL DVI input and (1) 4xSL DVI output, plus (4) input board slots that may house various input boards, plus (1) mezzanine location that may house various I/O boards. These slots are populated and configured at the factory. Table 1 shows the available I/O boards. The I/O boards and their location are defined directly in the part number, in the following format: EZwindow4K-LL-wxyzm, where w is the input board type in Slot 1 x is the input board type in Slot 2 y is the input board type in Slot 3 z is the input board type in Slot 4 m is the mezz board type I/O Board A BB M2 Function RGBHV,, NTSC/PAL, Component Input Card (only 1 input processed at a time) Dual DVI input (Dual Card occupies Slot 1 and Slot 2) DisplayPort 1.2 I/O Location(s) Any of Slots 1-4 Slot 1-2 or Slot 3-4 Mezz M6 HDMI 2.0 I/O Mezz Note: Table 1: Available I/O boards DisplayPort I/O supports RGB 4:4:4 mode only HDMI Input supports RGB 4:4:4 mode only HDMI output supports RGB 4:4:4, YCbCr 4:2:0 modes If a slot is unpopulated, then a # is placed in that location. For example, an EZwindow4K-LL-A#### has the following configuration: Slot 1 input board Slot 2 Not populated Slot 3 Not populated Slot 4 Not populated Mezz Not Populated I/O Board BB takes 2 slots, and is always in slot 1-2 or slots 3-4.
Part number: EZwindow4K-LL-AABBM2 describes a unit with: Slot 1 input board Slot 2 input board Slot 3/4 Type BB input board Mezz Type M2 Low Latency Plane Visual Inputs The EZwindow4K-LL has standard and optional low latency inputs. The standard low latency input is 4xSL, compatible with many computer graphics cards and projectors with stripe configurations, and resolutions up to 4096x2400. The optional low latency inputs are identified in Table 1 as type M boards. If a low latency input is utilized, it forms the Low Latency Plane Visual, and is the basis for the output timing. No re-sizing or retiming is supported on low latency inputs. Scaler Plane Visual Inputs The following (2) boards types provide inputs for windows that are sized and placed in the Scaler Plane Visual. : Multi-Format Input Board Supports the following inputs:, RGBHV, RGBsog, RS170, RS343, component, composite (NTSC/PAL). Any one of these inputs may be selected. Resolutions up to WUXGA with pixel rates up to 162MHz. Type BB: Dual DVI Input Board Supports a dual DVI input, for resolutions such as 2560x1600 and 2560x1440. Scaler Plane Segments The scaler plane is divided into segments for processing. The number of segments is 1 to 4, depending on output resolution and timing. The configuration application shows the segment boundaries within the output resolution. The segment sizes are based on output resolution and timing. Segments are generally vertical slices of the overall output resolution. Examples: a 3840x2160 output resolution at 60 Hz requires 4 segments, each 960x2160 a 3840x2160 output resolution at Hz requires 2 segments, each 1920x2160 a 2560x1440 output resolution at 60 Hz requires 2 segments, each 1280x1440 Scaler Plane Visual Windows Up to 4 windows can be placed in the Scaler plane. Each window is populated with an area-of-interest from any input card in Slots 1-4. Scaler Plane Methodology and Limitations Windowing within the scalar plane is accomplished by one of two modes: 1. Independent Windowing (IW) 2. Regional Windowing (RW) The mode determines how internal scaler assets are allocated, resulting in unique capabilities and limitations. The user will decide the windowing mode via the configuration application. Independent Windowing (IW): With this mode, up to 4 windows can be placed in the Scaler plane. The following constraint (IWC#1) is enforced by the configuration application: # of windows (segments utilized by window n) <= 4 n=1 IW allows each window to have independent horizontal and vertical scaling. Windows can be placed anywhere in the output resolution, tempered by IWC#1. IW supports rotation in 90 degree increments. IW also supports robust background fill colors. Figures 1 and 2 show several windowing possibilities for 4K 60 Hz and 4K Hz operation.. In most use models, Westar recommends Independent windowing. Regional Windowing (RW): With this mode, up to 4 regions can be defined in the Scaler plane (see Figure 3). Regions are not windows, but areas in the scaler plane. One or more windows can be placed in a region. A region is defined with the following parameters: Region[1-4] = Scaler Offset, Line Offset, Scaler Width, Line Height, Fill Color. A segment may include one region in the upper portion and another region in the lower portion. Upper and lower regions may have different zoom rates (or no zoom) but not shrink and zoom. RW has the following constraints (RWC): RWC# Description 1 A window resides in a single region. The window cannot span across multiple regions. 2 Windows cannot overlap within a region. 3 Horizontally, regions align with segment boundaries. 4 All windows within a region must zoom at the same rate. (Note 1) 5 Rotation is not supported 6 Window Fill Color (border) is drawn with the region fill color, so visible active video window borders are not currently possible. 7 The Video Lost Display Color is drawn with the region fill color, so a window disappears when video is lost at the input. 8 Windows within upper or lower regions of a segment cannot require both shrink and zoom. Note 2 Notes: 1. Windows within a region may shrink at different rates or stay pixel-forpixel. 2. In other words, there cannot be one window in a segment that is zooming while another window in the segment is shrinking. Display Plane Visual The EZwindow4K has both a foreground and a background layer. Each of these layers is selectable from the Scalar Plane, the Low Latency Plane, or a fixed RGB color. The Display Plane Visual (or output) is created by combining the foreground and background layer in one of several ways. A key can be applied to each pixel of the foreground. Based on the key result, the foreground, background, or any alpha combination of the 2 layers may be displayed.

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. Note: If single link outputs are used, then optional DP 1.2 or HDMI outputs are unavailable.

The SP2 (available separately from Westar) converts the 1080P image into a 3840x2160 image via to 4x Single Link DVI streams (each 960x2160), for input into the EZwindow4K. The HUD is created as a 1280x1024 image (or similar). This approach allows the HUD to be displayed in its native resolution on a 4K display device for maximum fidelity. For a given sized HUD, this approach allows 4x the pixel density for the HUD versus using a 1080 display device. This is an excellent method to upgrade projectors or display devices without changing the OTW IG.

Configuring the EZwindow4K The EZwindow4K is primarily used in applications where video is combined into a 4Kx2K image. The figure below shows the steps in setting up the EZwindow4K: Step 1 Set up Low Latency Plane Visual: Select I/O form, resolution, and timing of low latency pipe Step 2 Define inputs: video type, resolution If Low Latency input is used, it defines the Low Latency Plane Visual. Otherwise, a free-running output timing is generated. Display Origin 0,0 1024 Segment width Resolution and timing will define # of segments used. Input #1 800x600 Window origin V offset Segment height H offset 600x 600 2400 Step 4: Set up the Display Plane Visual: 600 x 600 Step 3 Set up Scaler Plane: Visual: Define windows (Input, area-of-interest, window size and location) Foreground will be Scaler Plane, LL input, or programmable color will be Scaler Plane, LL input, or programmable color. Display Plane Visual is the selected blending approach between foreground and background, such as RGB key, luma key, etc. Approach: 1. User sets up the Low Latency Plane Visual (if used) and Output formats. # of segments (stripes) required is calculated from format. Examples include: HDMI 2.0 Input, HDMI 2.0 Output, 3840x2160 60 Hz (4 Stripes) HDMI 2.0 Input, HDMI 2.0 Output, 3840x2160 Hz (2 Stripes) DP1.2 Input, DP1.2 Output, 3840x2160 4 Stripes DP1.2 Input, DP1.2 Output, 2560x1600 2 Stripes 4xSL DVI Input, 4xSL DVI Output 4096x2400 4 Stripes No input, HDMI 2.0 Output, 3840x2160 4 Stripes 2. User configures all Scaler Inputs in slots 1-4. Video type, resolution, etc. 3. User defines windows within the Scaler Plane Visual: User selects Independent Windowing (IW) or Regional Windowing (RW) approach. For each window, user selects an area-of-interest from an input and then defines the size and location of the corresponding window in the Scaler Plane Visual. For IW mode: The summation, from n = 1 to the # of windows, of segments utilized by window n must be less than or equal to 4: # of windows (segments utilized by window n) <= 4 n=1 4. The user creates the Display Plane Visual as a blended version of the Scaler Plane Visual and the Low Latency Plane Visual.
