Video Features

DVI Video Converter Features - SP2

Scaling, Combining, Windowing, & Area-of-Interest

  • Unlimited, independent horizontal and vertical scaling
  • Program image position within a larger background or foreground for each input
  • Reverse image left/right or flip top/bottom
  • Rotate image 90, 180, or 270 degrees
  • PIP performed by mapping each input to a location within the background. Z-ordering priority by input

Optional Video keying

  • RGB, Luma, or HSV Keying inside user-defined key area with programmable foreground & background alphas when key is true or false
  • Separate user-defined foreground and background alphas outside the key area


Combine 4 different video feeds (inputs 1-4) into a single 1080P video feed

The SP2 DVI converter is used to combine 4 different video feeds (inputs 1-4) into a single 1080P video feed. Each layout is easily configured by a hotkey command, making SP2 ideal for viewing multiple video sources. This can be performed on a SP2_C001.

Rotate and combine 3 different video feeds into a 1080P display

In this example, a SP2 is used to capture 3 different video feeds from a normal landscape raster, rotate and combine to allow a normal landscape 1080P display to be used as a portrait display. This can be performed on a SP2_C001.

Crop or scale 2560×1440 to 1920×1080 (1080P)

In this example, a SP2 is used to either take a 1920×1080 window out of a 2560×1440 image, or down-size a 2560×1440 image to 1920×1080. This allows a standard 1080P TV / monitor to be used to view hi resolution content. This can be performed on a SP2_C002.

Multi-IG Compositor combines 2 single link streams into one dual link DVI stream

In this example, an SP2 is used to ombine (2) image generator outputs into a single dual DVI output for a projector or monitor. This can be performed on a SP2_C005.

Multi-IG Compositor combines 2 dual link streams into one

In this example, a SP2 is used to combine (2) dual link DVI image generator outputs into (1) dual DVI output for a projector or monitor. This can be performed on a SP2_C006.

Taking portion of rotated dual DVI video and displaying on a standard monitor

Using an SP2, take a center portion of a 2560×1600 image, rotate it, and display on a standard UXGA or 1080P monitor. This can be performed on a SP2_C002.

Combining (2) Dual DVI projector feeds for Instructor Operator Station (IOS) monitor viewing

In this example, a SP2_C004 is used to combine a left projector feed and a right projector feed, each 2560×1600.  The two video feeds are combined and down-sized for viewing on a 1080P TV.

(Optional Feature) Keying on a video input to combine with 2nd input

In this example, a SP2_C001:Key is used to key a live video feed (in the foreground) over the map graphic (in the background). Using HSV keying, the greenish area (as well as the black, non-active area) becomes transparent, thereby passing the background.

Powerful Configuration Utility

Use Westar’s SP2 configuration utility to define the input timing, output timing, keying scheme (optional feature), and the area-of-interest within the source video and where to map the AOI within the output resolution. The configuration utility supports user-defined:

  • Input Timing and Output Timing
  • Video Scaling and Area-Of-Interest (AOI)
  • “Key” Processing (optional feature)
  • Border Colors
  • Image Flip (Horizontal and Vertical)
  • Image Rotate
