HDCP Key Management
Another aspect to HDCP is its use of “keys” to manage the handshaking that occurs
between any two devices. Every HDMI source device has a limit to how many
downstream devices it can support, determined by the number of HDCP keys it has
available. Rarely is that limit advertised or specified by the manufacturer or service
provider, so connect too many displays or processors and the source will simply stop
outputting a signal without warning.
To prevent such surprises, DM switchers test the HDCP limits of each HDMI source,
allowing the installer to configure the system around any limitations, or substitute a
different component.
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 switcher 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 switcher’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 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 switcher system can be commissioned in
as little as 15 minutes.
