HDCP Management
The switcher allows transmitting HDCP encrypted and unencrypted signals. The devices will be still HDCP
compliant as they will never output an encrypted signal to a non-HDCP compliant display device. If an
encrypted signal is switched to a non-compliant output, a red screen alert or muted screen will appear.
Protected and Unprotected Content
Many video sources send HDCP protected signal if they detect that the sink is HDCP capable – even if
the content is not copyrighted. This can cause trouble if an HDCP capable device is connected between
the source and the display. In this case, the content cannot be viewed on non-HDCP capable displays and
interfaces like event controllers. Rental and staging technicians often complain about certain laptops, which
are always sending HDCP encrypted signals if the receiver device (display, matrix router, etc.) reports HDCP
compliancy. However, HDCP encryption is not required all the time e.g. computer desktop image, certain
laptops still do that.
detect that the sink is not HDCP capable, and turn off authentication.
Disable Unnecessary Encryption
HDCP Compliant Sink
All the devices are HDCP-compliant, no manual setting is required, both protected and unprotected contents
are transmitted and displayed on the sink.
Not HDCP-compliant Sink 1.
Not-HDCP compliant sink is connected to the switcher. Some sources (e.g. computers) always send HDCP
encrypted signals if the receiver device reports HDCP compliancy, however, HDCP encryption is not required
all the time (e.g. computer desktop image). If HDCP is enabled in the switcher, the image will not be displayed
on the sink.
Setting the HDCP parameter to Auto on the output port and disable HDCP on the input port, the transmitted
signal will not be encrypted if the content is not protected. Thus, non-HDCP compliant sinks will display non-
encrypted signal.
Not HDCP-compliant Sink 2.
The layout is the same as in the previous case: non-HDCP compliant display device is connected to the
switcher but the source would send protected content with encryption. If HDCP is enabled on the input port
of the switcher, the source will send encrypted signal.
If HDCP is disabled on the input port of the switcher, the source will not send the signal. The solution is to
replace the display device to an HDCP-capable one.
