HDCP Encryption
The HDCP Encryption status can be viewed via SIS command and the front panel HDCP
LED Indicators.

HDCP Notification
HDCP notification provides an indication that encrypted content is trying to be displayed on
a non-HDCP compliant sink device. The requirements for the notification can be configured
for each output via SIS command (N HDCP).

Color Bit Depth
There are two options for color depth and deep color support. Color bit depth is
configurable for each output via SIS commands:

USB-C Input
The USB-C input supports USB data, audio, video, and USB power delivery. This input is a
USB 3.2 port, supporting up to 10 Gbps and backwards compatible with USB 2.0, 1.1, and
1.0.
DisplayPort Alt Mode
The DP Alt Mode is required for signal conversion to DisplayPort. After USB-C has been
converted to DP via DP Alt Mode, four DisplayPort lanes are available. The DisplayPort
signal is then converted to TMDS.
The USB-C input host controller can be configured to operate in one of two modes to
support a combination of high resolution video and USB via SIS. The four data lanes used
and shared by USB 3.x data and DP Alt Mode can be configured to operate in one of the
two modes:
•
Inputs — All inputs support content encrypted using HDCP 1.
Output — The output supports encrypting content using HDCP 1.x or HDCP 2.2.
HDCP Notification Enabled — A green screen is displayed on the output when the
input signal is encrypted and the display is not HDCP compliant.
HDCP Notification Disabled — A black screen is displayed when the input signal is
encrypted and the display is not HDCP compliant.
Automatic — By monitoring the EDID of the sink, the UCS 303 switcher determines
the best color depth that is supported by the sink. If the color bit depth of the signal is
supported, the signal passes unaltered. If the color bit depth is not supported, then the
signal is truncated to the maximum supported by the sink.
Force 8‑bit — When output is set to force 8-bit color bit depth, the unit always outputs
8-bit color bit depth.
This can also be disabled via SIS commands (see the
commands
on page 31) or PCS (see the UCS 303 Help File).
USB 3.x + USB 2.0 + 4k/30 video — Mode 1 (default)
The USB-C input host controller is configured so that two high speed data Lanes
operate in HBR2 mode (5.4 Gbps x 2 lanes = 10.8 Gbps). The two other high speed
data lanes are used for USB 3.2 (5 to 10 Gbps) operation.
