1. Introduction HDMI20-OPTC series – User's Manual 9
Standalone Application
Typical Application Description
The two Ethernet connectors on each extender make possible to daisy
chain the devices and build a local network where all the transmitters
(1..3) and receivers (1..3) are available via LAN.
They can be controlled by Lightware Device Controller (LDC) software
audio, Ethernet, and RS-232 signal to the receivers, so in this case,
the sinks can be controlled by Ethernet commands from the control
device (laptop).
signal to the transmitters which extend the stream to the receivers via
Receiver 1..3 represent three applications of the output modes:
▪ RX1 is in 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.
▪ RX2 is in 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.
▪ RX3 is in split mode. The receiver supports vertical splitting of
the HDMI 2.0 4K@60Hz 4:4:4 input signal to left and right halves
allowing for the transmission of a 18Gbps HDMI 2.0 signal over
two HDMI1.4 compliant links. The sink is a projector which is
able to recombine two half signals. Video signal is transmitted
to the Output 2 without any changing.
