The receiver is able to subsample the video stream in
YCbCr colorspace from 4:4:4 to 4:2:0.
HDMI 2.0 to 2x HDMI 1.4 Splitting
The device supports left and right column processing
of an HDMI 2.0 4K@60Hz 4:4:4 input signal, allowing
for the transmission of an 18 Gbps HDMI 2.0 signal
over two HDMI 1.4 compliant links. The two halves can
then be recombined at the signal destination.

Receiver 1..3 represent three applications of the output modes:
▪transparent mode (no conversion mode), the sinks are
stacked projectors. The video signal is HDMI 2.0 4K@60Hz
4:4:4 on the Output 1A and the Output 2 ports.
▪downsample convert mode (convert to YCbCr 4:2:0). The
LED screen 2 is 4K compatible and connected to the Output 2
port. LED screen 1 is not HDMI 2.0 4K@60Hz 4:4:4 compliant, so
the video processor in the receiver converts the HDMI signal from
4:4:4 to 4:2:0, and this way the sink will be able to accept the signal
on the Output 1B.
▪split mode. The receiver supports vertical splitting of
the HDMI 2.0 4K@60Hz 4:4:4 input signal to left and right halves

are not in use. Neutrik opticalCON DUO receptacle with 2x LC connector.
WARNING! Avoid eye exposure to beam! Direct intrabeam viewing normally hazardous.
INFO: Fiber optic cables can be easily damaged if they are improperly handled or installed. Handle the
optical cables with care to avoid damage.
LC Connector
One channel of the Neutrik connector is not used by the extenders for signaltransmission
and it is internally connected to the LC break-out connector. For more information about
break-out connector see Application Example with Break-out Connector section.
HDMI Input and Output Ports
The extender provides standard 19-pole HDMI connector with screw lock.
ATTENTION! Always use high-quality HDMI cable for connecting sources and displays.

The HDMI20-OPTC series transmitter can receive signal from two types of sources:
▪

The HDMI20-OPTC series receiver can output HDMI video signal (with embedded audio).

Receiver Side
The video and the embedded audio signal arrives via optical cable into the HDMI splitter. It duplicates HDMI
stream and transmits the signal without modifying it to the HDMI Out 2 port. The HDMI splitter transmits the
same signal into the video converter where three output conversion modes can be set.
Output Conversion Modes
In Transparent mode (no conversion mode), the video signal is transmitted to the HDMI Output 1A and the
HDMI Output 1B without any changing.
INFO: Maximal data transmission capacity of Output 1B is 9 Gbps, so the video signal is above, there will
be no picture on the display.
Split mode means splitting of the original video signal into left and right halves and sending the split signal to
the HDMI Output 1A and the HDMI Output 1B.
In Downsample convert mode (convert to YCbCr 4:2:0) the video converter subsamples the 4:4:4 signal to 4:2:0
on the 1A and 1B Output port.

Besides manual crosspoint selection you can
choose the Autoselect option on the video
ports. There are three types of Autoselect as
follows:
▪First detect mode: selected input port is
kept connected to the output while it
has an active signal
▪Priority detect mode: always the highest
priority active input is selected to
transmit.
▪Last detect mode: always the last attached
input is selected to transmit.

same type of port. The command is not processed by the CPU. Incoming serial data is forwarded from one
port to another port inside the extender.

The Concept
You can control the Projector over the extenders with the System controller. The controller is connected to
the local RS-232 port of the Transmitter which transmits the signal toward the Receiver
line. The Projector is connected to the local RS-232 port of the Receiver. The serial connection is bidirectional
which means the controller gets back the responses of the projector.
In this case the RS-232 port of the transmitter and receiver has to be set to Pass-through mode.
