DXP PRO SERIES MATRIX SWITCHERS - DVI HDMI
Digital Matrix Switcher Solutions
By Marc Booth, RGB Integration
With the increasing migration towards digital video systems many integrators are experiencing difficulty in adapting to the signal format.
Extron's DXP HDMI and DXP DVI Pro are Matrix Switchers designed to help minimise challenges of integrating digital through innovative features. Typically the three primary areas of concern for digital video integration are signal integrity, device compatibility and content protection. There is also the added consideration of the collective time these areas can add to the bottom line.
For digital video the first speed bump is always going to be the integrity of the signal. The Factors affecting signal quality are much harder to identify with digital compared to analogue systems and variations in product brands and quality can exasperate the problem. The DXP HDMI and DXP DVI Pro Matrix Switchers feature digital video signal conditioning for optimum performance.
The shape of RGB channels when viewed through a digital communications analyzer forms what is widely termed as an "eye pattern" when performance is at an optimum. As signal errors increase due to long cable runs, cable or termination quality the "eye pattern" begins to collapse resulting in video artefacts or in most cases no video at all. The DXP Matrix Switcher Series condition the video signal on each input by reshaping and restoring the RGB channels to correct levels while regenerating the clock channel to provide proper alignment.
DXP Series Matrix Switchers also offer extensive device compatibility through two exclusive features EDID Minder® and Key Minder™. In the digital video world EDID (Extended Display Identification Data) is a set communications that allow a display to identify to a source device its operational capabilities. The source is then able to generate signal that match the needs of the display for optimal performance. Matrix Switching presents the most challenging operational environment for EDID since the displays connected are likely to be of various models and native resolutions. Extron's EDID Minder manages the simultaneous EDID communications for inputs and outputs to ensure consistent and reliable switching performance. Key Minders responsibilities are very similar. HDCP (High-bandwidth Digital Content Protection) is an encryption protocol used by Blu-ray players to copy-protect the digital media being played. This protocol involves the swapping of unique keys that are validated between each switch to a source that requires HDCP authentication from a display. Key Minder continuously communicates the HDCP compliant information between the DXP Matrix for quick, reliable switching between inputs and outputs.
The DXP HDMI and DXP DVI Pro feature an immediate visual confirmation when devices that are connected to the Matrix Switcher are not HDCP compliant. Typically non-compliant devices display no image, unless quickly identified it can lead to a significant loss of time diagnosing a problem. DXP Matrix Switchers simply display a green screen to visually confirm that copy protected content cannot be viewed.
