Enova DGX HDMI Boards
77
Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Supported Number of Sinks
HDCP Source Device
The number of sinks that the source device supports is not relevant when using Enova DGX Switcher boards that support
HDCP because the input connector on the board is the only sink that the source device needs to authenticate.
Enova DGX Switcher
The HDMI outputs in an Enova DGX Switcher each support a maximum of 16 downstream devices (repeaters and/or
destination devices).
Unsuccessful Transmission in System
If an Enova DGX Switcher does
not
successfully transmit the protected content to any of the routed sinks, it may
indicate one of the following conditions:
Non-compliant device – The sink device is not HDCP compliant or has had its authentication key revoked.*
HDMI output sink support limit exceeded – The output is actively routed to more than 16 downstream
devices (display devices and/or repeaters) from a single output connector on an Enova DGX Switcher.
* Key revocation is handled strictly by the Enova DGX Switcher. The source does not take any action with respect to
revoked keys.
Important:
Keep in mind that a “failure condition” (in which HDCP authentication fails to occur) is verified by
the Enova DGX Switcher not the source device
and will result in the image being a dark red.
Note:
Be aware that even when you are playing un-encrypted content on a Blu-Ray player, most Blu-Ray
players play all content as encrypted content. Normally the Enova DGX Switcher switches non-encrypted
content without problems if the display is non-HDCP compliant. However, when encrypted content is sent
from a Blu-Ray player to the Enova and is switched to an output board (e.g., SC Optical Board) or a device
that does not support HDCP, the content will not display and the image will be red.
InstaGate Pro
®
Technology
InstaGate Pro Technology eliminates latency (time required for authentication) in the switcher for HDCP negotiations
with the displays in a system. The latency is typically experienced when HDCP authenticates HDMI source and
destination devices every time a new switching combination between a source device and display occurs.
With InstaGate
Pro Technology, when a source requires HDCP encrypted content, the inputs and compliant downstream devices are
automatically authenticated – it just works. Key limitations on source devices are also eliminated by allowing them to
see only a single sink key from the HDMI Input Board’s input connection.
Note:
Some destination devices have a longer lag time than others between receiving a signal and displaying
that signal. Although InstaGate Pro significantly reduces the latency associated with HDCP authentication, it
cannot reduce the inherent lag time of a device as it syncs up to the newly switched video image.
