Extron electronic QGE 100 manual Features, Functional Overview, Image Capture and Distribution

Features

The QGE 100 features the following:

•Allows simple connection of a DVI or RGB source to an IP network.

•Streams standard, routable IP packets on an existing network or a dedicated media network.

•Lossless compression with 4:4:4, 24-bit color source reproduction maintains image fidelity while minimizing network bandwidth.

•Is compatible with DVI input resolutions up to 1920x1200 and analog RGB input resolutions up to 1600x1200.

•Auto-sensing and flexible signal acquisition circuitry simplify installation for both standard and non-standard sources.

•Operates independently of the source computer operating system and hardware and imposes no additional load on the computer CPU performance.

•Image compression and user-defined bit rate settings limit network traffic.

•Provides keyboard and mouse control over the source computer from a PC equipped with the QGE 100 Viewer software when the QGE 100 is streaming in unicast mode.

•Can interface hundreds of DVI or RGB inputs into a Quantum Elite Videowall Processor.

•If used with a Quantum Elite processor, decodes up to 28 QGE 100 streams per Quantum Elite card frame.

•Provides scalability by multicasting graphic inputs to multiple Quantum Elite card frames or computers running QGE 100 Viewer software.

•Can be used on LANs or managed private networks that support multicast traffic.

Functional Overview

The QGE 100 connects between a source computer and its monitor. A connection is made from the source computer to the DVI-I input on the QGE 100 (as either a DVI or analog signal), and the local monitor is connected to the active loop-out connector on the QGE rear panel.

Image Capture and Distribution

After the source computer is connected to the QGE 100, any changes to the computer screen content are captured and then compressed using a lossless compression algorithm. The compressed source data then leaves the QGE 100 via the 100-BaseT Ethernet connector, and is streamed across the network to a remote viewing device (see “Viewing the QGE 100 Data Stream” on the next page).

The QGE 100 Data Stream

The data stream originating from a QGE 100 is standard IP network data. This data can be routed, encrypted, decrypted, and so on, using standard networking peripheral devices.

The proprietary QGE 100 data stream cannot be viewed unless an Extron decoding application or processor (such as the Quantum Elite) is used.

By default, QGE data is sent using UDP unicast protocol, which allows only one viewing device to view the source at a time.
