Application of Timing Mode Settings - Example
The Concept
The two PCs play the same content and the playing time is in the same moment (Frame #4) in both cases.
The HDMI output ports of the upper UBEX receiver are set to free run. The differences between the actual
content of the connected monitors might be noticeable.
The HDMI output ports of the lower UBEX receiver are set to source locked so the video stream is generated
in the receiver which does not engage any delay compared to the original stream.

4.1.7. Bandwidth Limitation
The UBEX endpoints can transmit two video streams at the same time up to 20 Gbps bandwidth. When the
bandwidth limit is exceeded, the priority of the streams is the following:
Transmitter Side
The stream of the HDMI in 1 has the higher priority and the stream of the HDMI in 2 will not be transmitted
until the bandwidth limit problem is solved (the parameters of the video is still received by the receiver). In
that case the stream tile of the disabled stream become amber in the LDC software.
Status
Transmitter side
Enabled
Receiver Side
The switched stream of the HDMI out 1 has the higher priority and the stream of the HDMI out 2 is going to
be disabled (the parameters of the video is still received). In that case the stream tile of the disabled stream
become amber in the LDC software.
Status
Receiver side
Enabled
Transceiver Side
Thanks to the 20G full-duplex SFP+ interface the transceiver has no bandwidth limitation on the input and
output sides either. The device is able to receive and transmit 2x 4K60 Hz 4:4:4 24bit streams on both HDMI
ports.
Status
Transceiver side
Enabled
