DigitalMedia 8G™
You can’t talk about AV and home entertainment today without
talking about high-definition, and creating a professional HD AV
distribution system means handling the challenges that come with HDMI.
HDMI is the standard for interfacing high-definition AV equipment, but
despite its many benefits, wasn’t developed with multi-room distribution in
mind. So, as the leader in HDMI and control system technologies, Crestron
developed DigitalMedia (DM) to deliver the first complete HD AV
distribution system to take HDMI to a higher level. DigitalMedia allows
virtually any mix of HDMI and other AV sources to be distributed throughout
a room, building, or campus.
DigitalMedia 8G is the latest generation of DM, providing a true one-wire
transport for moving high-definition video, audio, and Ethernet over lowcost twisted-pair or fiber optic cable without any compression or
DM-MD8X8 8x8 DigitalMedia™ Switcher
repeaters. Engineered for ultra high-bandwidth and ultimate scalability,
DM 8G® handles uncompressed video beyond high-definition with support
for HDCP, Deep Color, and 3D. Audio capabilities include simultaneous
stereo and multichannel surround sound signals, with support for highbitrate 7.1 audio formats like Dolby® TrueHD and DTS-HD Master Audio™
as well as uncompressed linear PCM. All signals are transported over one
8-conductor twisted-pair wire or one strand of multimode or single-mode
fiber. DM 8G enables wire distances up to 330 feet (100 m) via DM 8G+™
(DM 8G over CAT5e)[1,6], 1000 ft (300 m) via DM 8G Fiber (DM 8G over
multimode fiber)[2,6], or 7.5 miles (12 km) via DM 8G SM Fiber (DM 8G over
single-mode fiber)[3,6].
The DM-MD8X8 provides full support for Crestron DigitalMedia 8G devices
as well as all first-generation DM CAT[4,6] and DM Fiber[5,6] products, letting
you take advantage of the latest Crestron DM technology without
compromising your existing investment.
Modular Architecture
The DM-MD8X8 features a modular architecture with 8 input card slots,
and 2 quad output card slots. Each card slot on the DM-MD8X8 is fieldinstallable, allowing for easy and flexible system configuration with the
ability to make changes to the system as needs change.
A wide selection of input cards is offered to support a complete range of
digital and analog AV signal types including HDMI, DVI, DisplayPort Multimode[7], SDI, RGB and analog video, SPDIF and analog audio,
and DigitalMedia.
One or two output cards may be installed to feed up to 8 DM Receivers/
Room Controllers using your choice of DM 8G+, DM 8G Fiber, DM CAT, or
DM Fiber. Output cards may also be used to feed additional switchers in
other rooms or buildings using any form of DM including long-distance DM
8G SM Fiber. HDMI outputs are available as well for direct connection to
centralized audio processors and video monitors.
Output Expansion
An HDMI “pass-thru” output is provided on every input card to allow the
inputs of up to 5 DM switchers to be daisy-chained, enabling the
configuration of very large distribution systems with many DM and HDMI
outputs. Using five DM-MD8X8 switchers, it is possible to support an
incredible 40 separate outputs.
surround sound, you may find yourself limited to 5.1 or even plain
old stereo.
DigitalMedia eliminates such conflicts by managing the EDID (Extended
Display Identification Data) that many devices use to communicate their
capabilities. 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.
A Scaler for Every Display
Scaling capability can be added to any DM system using select DM
receivers with built in high-definition scalers.[8] Through a distributed scaler
approach, DigitalMedia delivers an incredibly flexible and user-friendly
solution for routing multiple disparate sources to many different display
devices. By placing an independent high-performance scaler at every
display device, DM 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 a highdefinition 3D source to be viewed on lower-resolution 2D displays without
compromising the original signal, letting you share your theater’s full HD
1080p 3D image with smaller, lesser displays in the kitchen, bathroom,
and bedrooms.
QuickSwitch HD® Technology
Handling high-definition digital media means handling HDCP (Highbandwidth Digital Content Protection), the encryption scheme that content
providers use to protect their DVDs, Blu-ray discs, and broadcast signals
against unauthorized copying. 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.
Computer Compatibility
Besides handling every available HD video format supported by HDMI,
DigitalMedia also supports the distribution of DVI, DisplayPort Multimode[7],
and RGB computer sources, and is fully compatible with DVI computer
monitors up to 1920 x 1200 WUXGA.
Versatile Audio Routing
HDMI is the key to handling all the latest 7.1 surround sound formats like
Dolby TrueHD and DTS-HD Master Audio. Great for your high-end home
theater, but how do you share that same source with other audio zones in
the house?
EDID Format Management
With all of today’s varied AV sources comes a multitude of confusing video
and audio formats to keep track of, and chances are not every device in
your system supports all of the same formats. Such conflicts can wreak
havoc any time you route one source to more than one display or audio
component. For instance, the Blu-ray player that’s feeding your 1080p
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 the 20”
TV in the kitchen. And, instead of enjoying your theater’s incredible 7.1
DigitalMedia provides the answer, allowing for the simultaneous
distribution of multi-channel surround sound and two-channel stereo
signals from the same HDMI source. Using a choice of DSP-based input
cards, the DM-MD8X8 employs onboard digital processing to derive a
stereo down-mix from the original multi-channel signal. Both signals can
be routed separately or simultaneously from any of the switcher’s DM
outputs, allowing either signal to be selected for output at each DM
receiver location.
| 800.237.2041
DM-MD8X8 8x8 DigitalMedia™ Switcher
Back at the switcher, the digital stereo signal is also converted to analog to
enable sharing with every other room in the house via a Sonnex™, Adagio®,
or other multi-room audio distribution system. The DM-MD8X8 also allows
bulky surround sound processors and amplifiers to be located centrally
instead of at the display location via optional local HDMI outputs.
Built-in Ethernet Switch
In addition to transporting digital video and audio, DigitalMedia can also
extend 10/100 Ethernet out to each display and source device via DM
room controllers and select DM transmitters, providing high-speed
connectivity for any room device that requires a LAN connection.
Ethernet is also utilized internally by the Crestron control bus to manage all
of the DM devices in the system and provide display control in each room.
Through its Gigabit Ethernet port, the DM-MD8X8 provides a single-point
connection to a corporate LAN or home network, requiring just one IP
address for the complete DM system.
USB HID Switch
DigitalMedia lets you centralize ALL of your HD sources - not just
television receivers and DVD changers, but also media servers and
computers. Built-in USB HID (Human Interface Device) signal routing allows
USB HID compatible keyboards and mice to be connected at a remote
display location, conference table or presentation lectern, extending their
signals through to the centralized equipment via USB HID ports provided on
select switcher input cards.
CEC Embedded Device Control
The primary objective of every Crestron system is to enable precisely the
control desired for a seamless user experience. DigitalMedia provides an
alternative to conventional IR and RS-232 device control by harnessing the
CEC (Consumer Electronics Control) signal embedded in HDMI. Through its
connection to the control system, the DM-MD8X8 provides a gateway for
controlling many devices right through their HDMI connections, potentially
eliminating the need for any dedicated control wires or IR probes. Through
proper CEC signal management, DigitalMedia allows you to take control of
each device as you like.
Easy Setup
Via the front panel or using Crestron Toolbox software, every step of the
DM-MD8X8’s setup process is designed to be quick and easy, configuring
inputs and outputs automatically while letting the installer make intelligent
design decisions along the way. 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 as little as 15 minutes.
