Parameters
Identifier Parameter description
<sig_type> The video signal type
Example

æ pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.ForcedSignalType=HDMI
9.9.2. 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 backward compatibility, HDMI 2.0 only
requires the use of scrambling with data rates of above 3.4 Gbps per lane.
Command and Response

#scrambling

SET·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.ForcedScrambling=<scr_mode>
ç
pw·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.ForcedScrambling=<scr_mode>
æ
Parameters
The option can be set on the output ports to AUTO / ON / OFF.
Example
ç SET /MEDIA/PORTS/VIDEO/O1/SETTINGS.ForcedScrambling=AUTO
æ pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.ForcedScrambling=AUTO
Parameter values
DVI: the outgoing signal format is forced to be DVI.
HDMI: the outgoing signal format is forced to be HDMI.
AUTO: the outgoing signal format is set automatically according
to the audio presence in the video stream: if audio is present,
the signal format is HDMI.

9.9.3. Setting the Signal Conversion Mode

ATTENTION! The signal conversion can be set on the input and output ports as well, but setting the
desired signal at the output port is recommended. The signal conversion on the input side is mainly for
testing purposes.
Conversion #colorspace
The outgoing signal can be routed to the outputs with or without conversion as follows:
Command and Response
SET·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.Conversion=<conv_mode>

Parameters
Identifier Parameter description
<conv_mode> The video conversion
mode
*The availability of this property depends on the hardware version of the output board (V1x_) of the HDMI
port. The hardware version can be found in the
Info submenu in the LCD.
** The availability of 4:4:4 to 4:2:2 conversion depends on the hardware version of the output board (V2x_). The
hardware version can be checked in the
submenu in the LCD.
Example
ç SET /MEDIA/PORTS/VIDEO/O1/SETTINGS.Conversion=OFF
æ pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.Conversion=OFF
#colorspace
Parameter values
OFF: there is no signal conversion.
420 *: the signal is converted to the indicated color depth.
422**: The signal is converted to the indicated color depth. The
matrix switcher accepts video signals in 8, 10 and 12 bit color depth,
but the sampling pattern conversion is always made in 8 bit.
LEFT and RIGHT *: The device supports vertical splitting of an
HDMI 2.0 4K@60Hz 4:4:4 input signal to left and right halves,
allowing the transmission of an 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.
