HDCP output modes
• Follow input — Output is always authenticated but only encrypted when required by
input. HDMI authentication is continuous. DVI authentication occurs for a maximum of
10 seconds, then fails. This is the default mode.
•
Always encrypt output — Output is always authenticated and encrypted.
HDMI authentication is continuous. DVI authentication occurs for a maximum of
10 seconds, then fails.
• Follow Input (with continuous DVI trials) — Output is always authenticated
but only encrypted when required by input. Both HDMI and DVI authentication are
continuous.
• Always encrypt output (with continuous DVI trials) — Output is always
authenticated and encrypted. Both HDMI and DVI authentication are continuous.
TMDS output format
The TMDS output format has three components:
• Video format — either DVI or HDMI
• Color space — RGB, YCbCr 4:2:2, or YUV 4:4:4
•
Quantization range — either full (0‑255) or limited (16‑235)
By default, the input format is configured for Auto, which automatically forces RGB 4:4:4
Full, with the video format dependent on the source signal and the sink capabilities.
This can be forced using SIS commands (see
TMDS Output Format on page 30) or
PCS (see Output Configuration on page 20).
NOTE: If the input signal is YUV 4:2:0, it is passed through unaltered, regardless of the
TMDS output format setting.
Color depth and deep color support
There are two options for color depth and deep color support:
•
Automatic — By monitoring the EDID of the sink, the DA HD 4K PLUS device
determines the best color depth that is supported by the sink.
• Force 8-bit
This can be changed using SIS commands (see Video Color Bit Depth on page 29)
or PCS (see Output Configuration on page 20).
