These input cards are HDCP-compliant when used with HDCP-compliant displays. They
provide down-scaling of sources as required, and full source auto-detection.
NOTE: The HDMI connectors also support DVI signals with appropriate HDMI to DVI
cables or adapters.
HDCP authorization
HDCP authorization allows the unit to appear HDCP compliant or non-compliant to the
connected source. This is useful if the source automatically encrypts all content when
connected to an HDCP compliant device, if the displays in the system are not HDCP
compliant, or if the source is being shared to capture devices that do not support HDCP.
In a video system that should not transmit HDCP encrypted data, such as broadcast or
streaming environments, HDCP authorization should be disabled at the input to ensure
that the source content remains unencrypted when possible.
With HDCP authorization disabled, protected material is not passed. Each input can be
set to enable or disable the support of HDCP signals. If HDCP authorization is disabled,
the input does not negotiate with the source device and forces the source to transmit only
unencrypted video.
Input rotation
Sources that have their content pre-rotated can be rotated within the Quantum Ultra
Series processor to be displayed on standard, landscape formatted displays. This type
of content traditionally would originate from desktops that have portrait formatted local
displays, or custom graphics media that has portrait content rotated to fit into a standard
resolution.
Figure 16. Input Rotation
The Quantum Ultra Series HDMI input card can support rotation of two 1920x1080
sources at 60 Hz or one 3840x2160 source at 30 Hz. Additional sources can be rotated,
but the processing frame rate is reduced in half to remain within the available bandwidth
of the card (see the following examples).
The HDMI 4K PLUS input cards can support rotation of four 4K sources at 60 Hz.
Additional instances of the rotated sources can be produced, but at a lower frame rate.
