DigitalMedia thoughtfully manages all of the disparate AV signals and devices to deliver a transparent user experience, and to ensure an optimum video image and audio signal at every location.
Integrated Ethernet networking and USB distribution provide a complete connectivity solution combined with built-in Crestron control  for managing the displays and other room devices without necessitating any additional wiring. Support for 4K video also ensures support for the latest generation of computers and monitors with native resolutions beyond p and WUXGA. Engineered for ultra high-bandwidth and ultimate scalability, DM 8G provides a true one-wire lossless transport for moving high-definition video, audio, Ethernet, and control signals over a choice of twisted pair or fiber optic cable.
All signals are transported over one CAT type twisted pair cable or one strand of multimode or single-mode fiber. Streaming expands the capabilities of DM to remove all distance limitations and allow distribution to virtually any device — anywhere in the world. Streaming is an essential component of any complete DM system, allowing for high-definition signal routing to Crestron touch screens, digital signage displays, remote buildings, and global offices without requiring any new or dedicated wiring.
DigitalMedia with streaming affords the ability to distribute any combination of sources to virtually any device anywhere. Each streaming output supports resolutions up to HD p at bitrates up to 25 Mbps.
Built-in scaling enables fast, trouble-free switching between sources of any type or resolution up to p or WUXGA. Audio support includes stereo signals, as well as multichannel audio signals downmixed to stereo via any "DSP" type input card. HDCP management ensures that protected content cannot be distributed via streaming. Each streaming output is actually fed internally by two separate switcher outputs, allowing any two input sources to appear picture-in-picture or side-by-side in a single stream.
Instant, single-frame switching between two full screen images is also possible. The audio signals from both input sources can also be mixed, allowing both signals to be heard simultaneously. Streaming input capability enables IP cameras and other H. It also allows DM switchers to be bridged together across a campus or around the world, enabling simplified routing of HD content between buildings and global offices.
Streaming connections can be configured to stream directly to one or more specific IP addresses, or to use RTSP to manage the configuration of numerous connections automatically. Each card slot on the DM-MD8X8 is field-installable, allowing for easy and flexible system configuration with the ability to make changes to the system as needs change.
Viewing HDCP encrypted content requires a source device to "authenticate" each display and signal processor in the system and issue it a "key" before the content can be viewed.
Ordinarily this causes a complete loss of signal for up to 15 seconds each time a new source or display is selected anywhere in the system. To make matters worse, every source device has a limited number of keys available, so connect too many displays and the source will simply stop outputting a signal without warning. Not to worry — Crestron QuickSwitch HD manages the keys for every HDCP-compliant device in the system, maintaining continuous authentication for each device to ensure fast, reliable routing of any source to any number of display devices.
Whether switching between sources or TV channels, Auto-Locking significantly reduces the time it takes each device to sense the new signal and configure itself to handle the changes, virtually eliminating any noticeable gap while switching.
Such conflicts can wreak havoc any time you route one source to more than one display or audio component. The media source feeding your p or Ultra HD projector in the theater may restrict itself to a lower resolution, or even shut off completely, if someone decides to view the same signal on a smaller TV in another room. Via Crestron Toolbox software, the format and resolution capabilities of each device can be assessed, allowing the installer to configure EDID signals appropriately for the most desirable and predictable behavior.
By placing an independent scaler at every display device, DigitalMedia truly delivers the most flexible and user-friendly solution for routing multiple disparate sources to many different display devices. This "Distributed Scaler Approach" ensures an optimal image on every screen no matter what sources are selected.
Distributed scaling allows a high-res computer source to be viewed on any display in the building. It also allows an SD, HD, or Ultra HD video source to be viewed simultaneously on the 4K display in your theater and on lower-resolution displays throughout the house. Great for your high-end home theater, but how do you share that same source with other audio zones in the house?
DigitalMedia provides the answer, allowing for the simultaneous distribution of multichannel surround sound and two-channel stereo signals from the same HDMI source. Using a choice of "DSP" type input cards, the DM-MD8X8 employs onboard digital processing to derive a stereo downmix from the original multichannel signal.
Ethernet is also utilized internally by the Crestron control bus to manage the DM devices in the system and provide display control in each room. Crestron also offers USB extenders to enable the routing of virtually any type of USB peripheral to any host device, all managed through the DigitalMedia system. Every module communicates with the DM switcher over the local Ethernet network or via a direct connection to the LAN port of a DM transmitter or receiver.
CEC Embedded Device Control The primary objective of every Crestron system is to enable precisely the control desired for a seamless user experience. The switcher even tests and measures the length of each DM cable, automatically making the appropriate calibrations for optimal signal transmission to every room. With DigitalMedia, an entire 8x8 system can be commissioned in under an hour.
To configure a DM switcher complete with input and output cards, cables, and other peripherals, please use the DigitalMedia Switcher Configuration Tool. Delivers a unified HD signal distribution solution incorporating both point-to-point wired and IP streaming technologies Provides lossless HD AV signal routing over twisted pair copper wire or fiber Integrates video, audio, networking, and control over one wire or fiber strand Enables high-performance H.

The switcher can also route any USB-capable input to any output. The output remains high for as long as video is detected. This is especially true if resolutions or video wall modes change during the route change. When the input is low, the analogs have no effect. This allows audio to be routed independently from video. If audio breakaway is not enabled, the audio routes will follow the selected video routes. The output remains high for as long as audio breakaway is enabled.
