The DVI-Ramp 2 is a DVI to HD/SD video interface which can operate in one of the following four modes:
- Single Extraction — Pixel-to-Pixel mode, the DVI-Ramp 2 can process up to 16 bits per component when Dual Head or Dual Link DVI is used.
- Dual Extraction — Pixel-to-Pixel mode, the two channels are supplied using a Dual Head DVI connection to two SDI outputs resulting in two separate video streams. Pixel-to-Pixel extraction enables the highest possible quality by eliminating any perceptible scaling artifacts.
- Single Extraction — Scaling mode, a sizable and positionable window is used to specify which section of the original PC graphic image will be scaled up or down to fit the targeted SDI resolution. Built-in anti-flicker circuitry eliminates most of the flickering when the SDI output is interlaced.
- Dual Extraction — Fill & Key mode, the DVI-Ramp 2 can process and supply Fill & Key signals to an external keyer using up to 12 bits per component for professional, high-resolution color depths. Fill and alpha (key) graphics content are provided by the PC through the two DVI inputs of the unit (Dual Head operation). Preferably, DVI should be genlocked.
