Quantum processors for videowalls

Extron Electronics has shown off a line of multi-image display processors, featuring scalable input, output and windowing capabilities as well as image scaling technology.

The Quantum Elite is designed for large videowalls of up to 28 screens and larger, while the Quantum Connect is ideal for small to medium-sized videowalls, up to 14 screens.

Both processors are card cage designs that support various combinations of 12-input video cards, dual DVI/RGB input cards, and dual DVI/RGB output cards. The Quantum Connect features eight slots and can accommodate up to 84 video inputs or 14 DVI/RGB inputs, and up to 14 outputs, depending on the input and output card configuration. The Quantum Elite, designed for larger videowall systems, is available in 15-slot and eight-slot models. The 15-slot version supports up to 168 video or 28 DVI/RGB inputs, and up to 28 outputs. Multiple Quantum Elite units can be cascaded for accommodating display arrays of more than 28 screens. Both the Quantum Elite and Quantum Connect can display up to 126 windows per output. They feature a dedicated high-bandwidth video/graphic bus, maintaining real-time performance with no reduction in frame rate, even when the inputs are heavily loaded.

In addition to the input cards, the Quantum Elite supports RGB or DVI inputs streamed over IP networks from an Extron QGE-100 Quantum Graphics Encoder. The QGE-100 captures RGB or DVI computer-video images and streams them to Quantum Elite videowall processors. It is ideal for capturing text or data displays, or graphics with medium to low motion. Lossless compression applied in the QGE-100 enables the capture and interfacing of hundreds of computer-video inputs to the Quantum Elite, using low network bandwidth while preserving image quality.
