HDCP-compliant sink
HDCP-compliant sink
All the devices are HDCP-compliant, no manual setting is required, both protected and
unprotected content is transmitted and displayed on the sink.
Non-HDCP compliant sink (HDMI/DVI) 1.
Non-HDCP compliant sink displaying unprotected content
Non-HDCP compliant sink is connected to the receiver. 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 transmitter, 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.
Non-HDCP compliant sink (HDMI/DVI) 2.
Non-HDCP compliant sink and protected content
The layout is the same as in the previous case: non-HDCP compliant display device is
connected to the receiver but the source would send protected content with encryption. If
HDCP is enabled on the input port of the transmitter, the source will send encrypted signal.
The sink is not HDCP-compliant, thus, it will not display the video signal (but blank/red/
muted/etc. screen). If HDCP is disabled on the input port of the transmitter, the source will
not send the signal to the transmitter. The solution is to replace the display device to an
HDCP-capable one.
