4K Video Splitter - EZsplitter4K

EZsplitter4K-HD4 
4K DisplayPort to DVI Video Splitter

The EZsplitter4K-HD4 is the ideal solution for creating multiple DVI-D Display Output video streams of 1080P or less from a high resolution (up to 4K) DisplayPort source.

Features

Z

Input resolutions up to 4K

Supports DisplayPort input resolutions up to 3840×2160
Z

4 DVI display outputs plus repeater

4 DVI Display Outputs (DDO) up to 1920×1200 (Single link, including 1080P). For applications requiring more than 4 outputs, the EZsplitter4K-HD4 includes a DisplayPort video repeater output.

Z

Define up to 4 output windows

Up to 4 output windows can be defined. Some or all of the output window content can be mapped to any area-of-interest within the Input Plane (IP) via upscaling or 1:1 pixel mapping. View Block Diagram

Applications

Splitting a single IG channel into multiple display heads.

If your image generator is creating content for multiple display devices, the EZsplitter4K-HD4 can separate out individual video windows within the stream to drive different displays. View Example Applications

Seamless content switching for multiple displays driven by a single image generator

The EZsplitter4K-HD4 can be configured to a map and seamless switch content for (4) DVI-compliant Multi-Function Displays (MFD) up to 1080P from a single IG channel. View Example Applications

Input Features

  • DisplayPort input resolutions up to 3840 x 2160 forms the Input Plane
  • The DisplayPort input is available on a DisplayPort repeater output, for further processing by downstream components

    Optional Keying

    • Optional keying (:Key) allows any Keyed Content x over Content y, where x and y may be any output window or alpha combination of output windows. (Requires option :Key)

      *Features that are not yet integrated but will be in field upgradable future revision

      Output Features

      • (4) DVI Display Outputs (DDO) up to 1920×1200 (Single link, including 1080P). DDOs have a common resolution and timing
      • Image content of each DDO is an alpha combination of one or more Output Windows (OW)
      • Up to four OWs. Each OW resolution is less than or equal to the DDO resolution
      • The image content of an OW is a scaled Area-of-Interest from the input plane (up-scaled or 1:1). Balance is a programmable fill color.
      • *Scaled DisplayPort output for specialty applications. If enabled, DVI outputs are not available.

      Example Applications

      Multiple displays driven by one Image Generator

      In the figure below, a single IG channel is used to create content for (3) DVI-compliant displays up to 1080P, plus additional content for
      specialty conversion, such as NTSC or PAL (for a recorder) or a Stanag format for a specialty display. Content for each display is a fixed
      location in the IG image.

      The specialty video formats are created with the standard EZsplitter (input up to 1080P)

      Seamless content switching for multiple displays driven by one Image Generator

      In the figure below, a single IG channel is used to create content for (4) DVI-compliant Multi-Function Displays (MFD) up to 1080P.
      Content does not need to be a fixed location in the IG image, Instead, each of the 4 output windows are available to any of the 4 displays. A
      display may be mapped to an output window instantly via an alpha command for each EZsplitter4K DVI output. An alpha command selects 1
      output window or an alpha blend combination of any of the output windows.

      Seamless content switching for multiple displays driven by one Image Generator, with keying

      Content does not need to be a fixed IG image, Instead, each of the 4 output windows are available to any of the 4 displays. A display may be mapped to an output window instantly via an alpha command for each EZsplitter4K DVI output. An alpha command selects 1 output window or an alpha blend combination of any of the output windows. Note: Keying is an optional feature.

      With keying, the display content is formed from a foreground layer and a background layer for each DVI output, as follows:

      • The foreground layer can be 1 output window, or an alpha blend combination of any of the output windows.
      • The background layer can be 1 output window, or an alpha blend combination of any of the output windows.
      • The display content is then formed by RGB keying or luma keying on the foreground layer.

      A key calculation is performed on each foreground pixel. The programmable key area has programmable foreground and background alpha
      values for key = true and key = false. Outside the key area also has a programmable foreground alpha value and background alpha value.

      Re-sizing or Rotating High Resolution DisplayPort

      *The EZsplitter4K supports upscaling, downscaling and rotation of DisplayPort video at resolutions up to 4K 60 Hz. When using the DisplayPort output, DDO1-4 outputs are inactive. Please contact the factory to discuss your specific application.

      EZsplitter4K-HD4

      DisplayPort up to 4K @ 60Hz
      Up to (4) DVI Display Output (DDO) streams
      Each DDO resolution and timing are identical
      DDO resolution up to WUXGA @ 60Hz). Note: Customer may use readily-available HDMI-to-DVI cables.

      (1) DisplayPort repeater output (same timing and resolution as DisplayPort input)

      *Scaled DisplayPort mode supports (1) Scaled DisplayPort Output (up to 4K @60Hz).
      [If this mode is used, DDO streams are not available]
      Up to 4 output windows (OW) may be defined. Each OW resolution is less than or equal to the DDO resolution.

      A scaled AOI (SAOI) can be assigned to an OW. The SAOI is mapped to any area-of-interest (AOI) in input resolution as a 1:1 mapping or an upscaled image (No downscaling). Balance of OW (non SAOI area) is a programmable fill color.

      Each DVI Display Output (DDO) is an alpha combination of 1 or more OW’s. Note: If the alpha combination of 1 or more OW’s does not cover the entire DDO resolution, then the unused pixels are black.

      Optional: Keying between a foreground layer and background layer for each DVI output, where each layer can be any output window or an alpha combination of output windows.
      DC Power Connector, 12 VDC +/- 10%, less than 40 Watts with ac/dc adapter
      USB
