6.2.5 DVI signals with copyright protection
The HDC does not support the long-distance transmission of DVI signals that are protected by HDCP
(hereafter referred to as “DVI signals with HDCP”).
Use IDK’s HDBaseT product supporting DVI signals to transmit DVI signals with HDCP.

[Fig. 6.3] Configuration example of DVI signals with HDCP
If both source and sink devices have an HDMI connector, HDMI signals are output; if either or both have a
DVI connector, DVI signals are output. However, even if both connectors are for HDMI, sometimes DVI
signals will still be output. Note that signal type to be output cannot be determined only by connector shapes.
Example: DVI signals are output even when a projector with an HDMI connector is connected.
Some source devices will check the EDID of the projector, and if the audio is not compliant, DVI signals will be
output instead of HDMI.
