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
• Single Extraction - Scaling
• Dual Extraction - Pixel-to-Pixel
• Dual Extraction - Fill & Key (using external keyer)
In
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. With
the Dual Extraction - Pixel-to-Pixel mode, the 2 channels are supplied
using a Dual Head DVI connection to two SDI outputs resulting in 2
seperate video streams. Pixel-to-Pixel extraction enables the highest
possible quality by eliminating any perceptible scaling artifacts.
In
Single Extraction - Scaling mode, a sizeable 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
In
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 2 DVI
inputs of the unit (Dual Head operation). DVI should be genlocked
preferably.
The unit can be externally synchronized with an
analog reference (SD or HD) or can free run on its internal
frequency-accurate time base.
For convenience and flexibility,
configuration and control of the DVI-Ramp 2 can be done via USB, RS-232
or Ethernet. Firmware updates are performed by USB or RS-232 only.
The
DVI-Ramp 2 is packaged in a free-standing case, suitable for
installation on a desk. Two units can be installed side-by-side on a
1RU tray for rack mounting, using TRAY-120.
Key Features and Benefits
- Graphic to HD/SD video interface with four operating modes
- Built-in Scaler
- Uto 16 bits per component when using 2 DVI channels for high-resolution color depths
- Genlockable to an external analog reference signal (SD or HD)
- Platform/OS independent
- External-to-the-PC design: will not consume any precious CPU/GPU cycles from the PC to perform video processing
- Rack-mountable (half-rack unit) or desktouse
Typical applications
Graphic to video in post-production
DVI-Ramp 2 can perform pixel-to-pixel extraction for high quality graphic to video conversion.
Broadcast keying of 3D animation using character generation and virtual set
DVI-Ramp 2 provides elegant interfacing for keying HD/SD 3D animations over a background using a mixer.
Web graphics to video for broadcast
Broadcasters can quickly and easily extract web graphics and take them on-air with DVI-Ramp 2.
Digital Cinema (4K projection)
Four DVI-Ramp 2 interfaces can be used to feed a 4K Digital Cinema projector.
