6.4.2.4 Managing the HDCP detection

The VIO 4K is compliant with the HDCP specification for DVI, HDMI and DisplayPort inputs.

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).

Output control

• With HDCP enabled (default), the HDCP encryption is maintained whether the screen is compliant or

not.

• With HDCP disabled, all screens are seen as non-HDCP compliant.

TIP: Disable HDCP as much as possible, especially if not using HDCP-encrypted sources.
