HDBaseT Certified
Crestron DigitalMedia 8G+™ technology is designed using HDBaseT Alliance
specifications, ensuring interoperability with third-party HDBaseT products.
Via DM 8G+, the DM switchers can be connected directly to any HDBaseT
compliant device without requiring a DM transmitter or receiver. HDBaseT
connectivity through the DM switchers converges uncompressed full HD digital
video, audio, Ethernet, power and control signals through a single CAT5e or CAT6
cable over distances up to 330 feet (100 meters).

Modular Architecture
The DM-MD64X64 features a modular architecture with 8 input blade slots and 8
output blade slots; the DM-MD128X128 features a modular architecture with 16
input blade slots and 16 output blade slots. Each blade slot on the DM switchers are
field installable, allowing for easy and flexible system configuration with the ability
to make changes to the system as needs change. The input and output blades are
hot-swappable to facilitate servicing without shutting down the whole switcher. I/O
blades are offered to support the choice of HDMI, HDBaseT, analog audio,
DM 8G+, DM 8G fiber, and DM 8G single-mode fiber. Each blade provides 8 inputs
or outputs of any one type.

QuickSwitch HD
Handling high-definition digital media means handling HDCP, 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. In addition, every source device has a limited
number of keys available; therefore, if too many displays are connected, the source
stops outputting a signal without warning. Crestron QuickSwitch HD, however,
manages the keys for every HDCP-compliant device in the system, maintaining
continuous authentication for each device to ensure fast and reliable routing of any
source to any number of display devices.
Auto-Locking Technology
Crestron Auto-Locking technology enables super fast signal switching by
instantaneously configuring every device in the signal path as soon as the signal hits
the first device. 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.
EDID Format Management
DigitalMedia manages the EDID (Extended Display Identification Data) that modern
digital devices use to communicate their capabilities. Through the DM switchers, the
format and resolution capabilities of each device can be assessed, allowing the
installer to configure EDID appropriately for the most desirable and predictable
behavior.
1. DM 8G+ and HDBaseT input is a future feature that will be enabled through a future input blade.
2. Onboard HDMI output and analog audio input and output are future features that will be enabled
through a future output blade and other components.
