• Image Manipulation — Any portion of an input image can be
extracted and expanded to fill the output raster. Image characteristics
such as brightness, saturation and gamma can be adjusted. The system
also enables you to zoom, pan and freeze an input source, and if the
size of the output image is reduced, the background can be black, a
solid color, or a shaded color.
• Remote control — Using a command line interface, complete system
control is supported via the RS-232 serial port or the 10/100 BaseT
Ethernet port. Many control parameters can be stored in non-volatile
memory for later use.
• High-resolution output — The format for each channel’s high-
resolution RGB and DVI outputs is independently adjustable (up to
1600 x 1200 pixels). Each output channel can be set to a different
resolution, depending upon your application requirements.
• Auto sync — Quadra automatically detects and locks to all computer
sync signals. Industry standard and custom video timings are
supported.

Each Quadra input channel accepts any one of the component, composite, RGB
and (optionally) digital inputs. Using control commands, users can
dynamically switch between any one of the input sources, but the limit of one
source per channel remains in effect.
For example, you could connect RGB from a PC, S-Video from a camera and
Composite video from a VHS tape deck — all to input 1’s input connectors,
and then switch between them using control commands.
Please note the following important points regarding inputs:
• Video inputs can originate from devices such as TV cameras, video
cassette recorders, DVD players or video teleconferencing systems.
• Analog RGB inputs typically originate from a computer. These inputs
can be interlaced or non-interlaced, up to 1600 x 1200 pixel resolution,
and refresh rates (or frame rates) up to 200 Hz.
• The system’s computer inputs can be configured with any sync format
(sync on green, composite sync, or separate H- and V-drive).
• Because the Component and RGB input signals use the same 15-pin
“D” input connector, you can not connect both RGB and component
inputs to a given channel simultaneously.
