10.1 HDCP
10. APPLICATIONS NOTE AND TIPS
HDCP is a content protecon mechanism which uses encrpyon to prevent high value content from being
delivered to non-authorized devices. For example, Blu-ray players use HDCP on their HDMI outputs to ensure
that the HDMI output cannot be routed to a digital recording device.
The QuickMatriX is fully HDCP compliant, meaning that you will be able to use the QuickMatriX to accept
HDCP protected sources and route them to any HDCP protected outputs. As Analog Way is a licenced HDCP
adoptor, this also means that the QuickMatriX is prevented from displaying any HDCP protected images on
any non-HDCP compliant outputs (as is the case for all licenced HDCP compliant devices).
HDCP can only be used on certain connecon formats, including DVI, HDMI, and Displayport. Keep in mind
that simply because a connecon is using a DVI, HDMI, or Displayport connecon, it does not guarentee
that the devices connected are maintaining an acve HDCP connecon. For example, you may nd video
recording or capture devices equipped with an HDMI input, however HDCP licencing forbids these devices
from capturing HDCP protected content.
HDCP is not supported on connecon formats such as composite, component, Svideo, SD-SDI, HD-SDI,
3G-SDI, or VGA. This means that any source which becomes protected by HDCP cannot be converted to
these formats. For example, while you may nd a Blu-ray player which can directly output a composite video
signal, HDCP licencing forbids converng the HDCP protected HDMI signal back to composite or any other
non-protected format.
To help troubleshoot HDCP in your installaon, each input and output page is equiped with HDCP status
informaon to indicate in realme when HDCP encrypon is being used.
Certain devices such as Macintosh computers can be misleading to use in conjuncon with an HDCP compliant
presentaon switcher such as the QuickMatriX. This is because devices like the Mac computers can be used
to output both HDCP protected content (such as a movie downloaded from iTunes) as well as non-HDCP
protected content (such as a Keynote presentaon or the desktop). When a computer rst connects to an
HDCP compliant device such as the QuickMatriX, it learns the capabilies of the device through the EDID
connecon. Upon seeing the HDCP compability of the aached QuickMatriX, devices like the Mac computers
will immediately aempt to use HDCP encrpyon at all mes, despite the content currently displayed on the
computer screen. Since this source would now be considered an HDCP protected source, the QuickMatriX
would be required to prevent it from being displayed on VGA or SDI outputs and only allow it to be displayed
on outputs protected by HDCP. To work around this problem, the QuickMatriX allows the HDCP features of
a parcular input to be disabled, which in turn informs the Mac computer to avoid using HDCP, and allows
content such as Keynote and the desktop to be displayed, as this input will no longer use HDCP protecon.
Please note that disabling the HDCP features of the input do not circumvent HDCP protecons, and thus do
not allow you to view any content which requires this protecon.
