5.2.5 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 our HDC-D100 extender that supports DVI signals for transmission over twisted pair cable signals
providing HDCP support.

HDMI signals Supported Supported
DVI signals Not supported Supported
* Depends on the combination of source and sink devices
[Figure 5.5] 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.

5.2.6 Cascade connection
Distribution amplifiers and multi switchers that are HDCP-compliant repeaters can be connected, and can be
configured in a cascade connection using IDK’s HDC-D100 twisted pair cable extender that supports DVI
signals. However, cascade connection is not available in the following cases:
● HDC-TH/RH100 and another set of HDC-TH/RH100 (IDK’s twisted pair cable extender supporting
HDMI signals)
● A repeater that only supports HDCP pass through (Example: Switchers, boosters)
