5.1.4. HDMI Signal Transmission - Example for TX-RX Pair
The Concept
Two source devices are connected to the UBEX transmitter: a 4K laptop built with a 4K graphic card (output
signal: 4K60) and an HD laptop (output signal: 1080p60). Two sink devices are also connected to the local
output ports of the transmitter: a local 4K TV and a local monitor.
The two streams from the 4K laptop and the HD laptop are transmitted to the UBEX receiver via the fiber
optical line.
Two local source devices are connected to the UBEX receiver: a Playstation and a Blu-ray player. The signals
can be only transmitted over the output ports of the receiver.
The receiver is able to copy the signal of the HDMI out 1 to the HDMI out 2. If any signal modification
(scaling, color space changing, etc) has been applied, the modified stream will be copied.
The receiver transmits the selected streams toward two sink devices: a 4K TV and a full HD (1080p) monitor.

The local output ports of the transmitter are fixed: the HDMI out 1 transmits the HDMI in 1 stream, the
HDMI out 2 transmits the HDMI in 2 stream.
The streams coming from the transmitter can be switched between the two output ports of the receiver. For
example the HDMI in 1 stream can be switched to the HDMI out 1 and out 2 as well.
Scaling Options
If the stream of the 4K laptop is switched to the HD monitor on the HDMI out 1, it cannot display the high-
resolution video. The solution is the stream transmitted on the HDMI out 1 can be scaled for the sink device
which supports lower resolutions only. For example the 4K60 video is scaled to 1080p60 and the stream can
be displayed on the HD monitor as well.
The scaler is available on the receiver and transmitter side either. The stream of the HDMI in 1 can be re-
scaled and the transmitter transmits the optimized stream toward the receiver.
