Auto‑switching
The transmitter can automatically select an active, connected input based on a configured priority using
auto-switching.
When auto switch is enabled, it can be configured via SIS commands (see
PCS (see the DTP3 T 212 D Help File):
Disabled
•
Auto-switch disabled. Inputs must be manually selected.
Enabled (default)
• Highest Active Input — By default, priority is given to the highest active input.
•
Lowest Active Input — Priority is given the lowest active input.
HDCP
Input
The HDMI and USB-C 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.
Outputs
The output is pre-authenticated and encrypted, in accordance with the configured HDCP output mode using SIS
commands (see Output HDCP Mode
HDCP output modes
•
Follows input (default) — Output is only encrypted when the input signal is encrypted.
• Always encrypt — Output encrypts the video regardless of whether the input video is encrypted or not.
HDCP Authorized setting
The HDCP Authorized setting, configurable via SIS commands (see
or PCS (see the DTP3 T 212 D PCS Help File), is for devices such as Mac computers, iPhones, iPads, and some
Windows 7 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.
