USER MANUAL
The
VIO 4K
is compliant with the HDCP specification for DVI, HDMI and DisplayPort input and output plugs.
INPUT DETECTION
On DVI, HDMI and DisplayPort input plugs, the HDCP detection is automatically managed by the input
components.
OUTPUT DETECTION
On DVI-I (digital part only), HDMI and DisplayPort output plugs, the HDCP detection is automatically
managed according to one of the following criteria:
•
Hot plug
•
3-second period attempt
By default, the HDCP detection is enabled on all input and output plugs that support the HDCP specification
(SEE:
HDCP detection
).
If an input source is HDCP-encrypted, the output availability is then negotiated according to the following
criteria:
HDCP source
(*)
Non-HDCP source
HDCP output
peripheral
Output content is available only if HDCP
is enabled on both the input and output
plugs.
Output content is available,
whichever the status on the
output plug.
Non-HDCP
output
peripheral
Output is blackened even if HDCP is
enabled on the output plug.
(*) Only on video plugs standard that support HDCP (HDMI, DisplayPort, DVI).
By enabling and disabling HDCP, you can thus relatively control the whole HDCP stream:
Input control
•
With HDCP enabled (default), the HDCP negotiation is maintained even if the DVI, HDMI or
DisplayPort plug is not the current plug (active input).
•
With HDCP disabled, none of the HDCP sources can be displayed (the sources will see the VIO 4K
inputs as non-HDCP compliant).
