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.

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 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.
*The availability of this property depends on the hardware version of the output board (V1
x
_) of the HDMI
port. The hardware version can be found in
in the LDC or in the
submenu in the LCD.
