HDCP
Input
The HDMI inputs negotiate and authenticate HDCP with the source device if the source
requires HDCP encryption. The authentication process is repeated whenever the stored
EDID is changed or updated, which is indicated by pulling HPD low.
HDCP support can be disabled for each input independently using the SIS command (see
HDCP Commands
Outputs
The output is pre-authenticated and encrypted, in accordance with the configured HDCP
output mode using SIS commands (see
the DTP2 T 204 PCS Help File).
If the output requires encryption but the connected sink device cannot be authenticated, the
output displays a green or black screen (see "HDCP notification," below).
HDCP output modes
Follow input — Output is encrypted only when the input signal is encrypted.
•
•
Always encrypt output — Output encrypts the video regardless of whether the input
video is encrypted or not.
HDCP notification
HDCP Notification provides an indication that the unit is trying to display encrypted content
on a non-HDCP compliant sink or display device. These requirements apply to the HDMI
output.
•
HDCP Notification enabled — When the input signal is encrypted and the connected
display is not HDCP compliant, a green screen is displayed on the output.
HDCP Notification disabled — When the input signal is encrypted and the connected
•
display is not HDCP compliant, a black screen is displayed on the output.
HDCP Authorized setting
The HDCP Authorized setting, configurable via SIS commands, is for devices such as Mac
computers, iPhones, iPads, and some Windows sources that always encrypt their output, if
the downstream sink is HDCP compliant.
•
HDCP Authorized On — The HDMI inputs indicate to the sources that they are
capable of handling HDCP content.
When an encrypted or unencrypted source is connected, the video is passed through
the system.
HDCP Authorized Off — The HDMI inputs indicate to the sources that they are not
•
capable of handling HDCP content.
When a Macbook, or any of the other devices listed above, is connected, the output
video is unencrypted.
When a source playing content that requires video encryption (for example, Blu-ray) is
connected, the source does not output video.
