QuickSwitch HD
Handling high-definition digital media means handling HDCP (High-bandwidth
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. 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-MD64X64,
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.
A Scaler for Every Display
Scaling capability can be added to any DM system using select DM receivers (sold
separately) with built-in high-definition scalers. By placing an independent
high-performance scaler at every display device, DigitalMedia 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 regardless of the sources that are selected. Distributed scaling
allows a high-resolution computer source to be viewed on any display in the
building. It also allows a high-definition 3D source to be viewed on lower resolution
2D displays without compromising the original signal, letting a theater’s full HD
1080p 3D image be shared with smaller, lesser displays in other rooms.
Built-In Ethernet Switch
In addition to transporting digital video and audio, DigitalMedia can also extend
10/100 Ethernet to each display and source device via select DM receivers and
transmitters (sold separately), 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-MD64X64 provides
a single-point connection to a corporate LAN or home network, requiring just one IP
address for the complete DM system.
