Video settings
Conversion
mode
Passthrough:
no signal conversion.
4:4:4 to 4:2:0 :
the signal is converted to the the
indicated color depth.
LEFT part
and
RIGHT part
: The device supports
vertical splitting of an HDMI 2.0 4k@60Hz 4:4:4
input signal to left and right halves allowing for
the transmission of a 18Gbps HDMI2.0 signal
over two HDMI1.4 compliant links. The two
halves can then be recombined at the signal
destination. To apply the feature route the same
input signal to 2 output ports. Set the conversion
to
Left
on one output port and
Right
on the other
output port. See the application diagram in the
chapter.
Scrambling
HDMI 2.0 standard introduced scrambling to the
TMDS encoding which helps to decrease the
energy peaks and hence the Electro Magnetic
Interference (EMI). To maintain backwards
compatibility, HDMI 2.0 only requires the use
of scrambling with data rates of above 3.4
Gbps per lane. The feature can be set on the
output ports to
Forced On / Forced Off
,
or
Auto
(recommended).
TMDS clock rate Setting the value to
1:10, 1:40,
or
Auto
(recommended).
Factory defaults
Resetting the default values:
HDCP
= auto,
Signal type
= auto,
Conversion mode
= passthrough,
Scrambling
= auto,
TMDS clock rate
= auto.
Audio settings
Mute analog
output
The analog audio output signal can be muted by
this option.
Analog output
volume
Setting the value between -95.62 dB and 0 dB.
Analog output
balance
Setting the value between -100 and +100 (0 =
center).
Factory defaults
Resetting the default values:
Analog output
= unmuted,
Analog output volume
= 0,
Analog output balance
= 0 (center).
Video status and Embedded audio
The signal format and the detected parameters are described in
these sections.
HDCP status
The currently applied HDCP encryption level (e.g.
HDCP 1.4).
HDCP stream
type
non HDCP signal:
the signal is not encrypted.
HDCP 1.4 stream:
the signal is encrypted with
HDCP v1.4
HDCP 2.2 stram (HDCP 1.4 convertable):
the signal is
encrypted with HDCP 2.2 but can be converted
to be encrypted with HDCP v1.4. See the
corresponding section section in
(the
first figure).
HDCP 2.2 stream (non HDCP 1.4 convertable):
the
signal is encrypted with HDCP 2.2 and not
allowed to convert and encrypt with HDCP v1.4.
In this case the signal can be displayed only on a
HDCP v2.2 compliant sink device.
