The Concept
The UMX-TPS-TX140K transmitter device has two video sources: a PC which sends analog video signal over
VGA; and a Blu-ray player which sends digital video signals over HDMI. The transmitter transmits one of the
video signal over TPS interface to the receiver. The transmitted signal is always converted to digital HDMI
with embedded audio signal.
The HDMI-TPS-RX220AK receiver has has two source devices: the transmitter over TPS; and a laptop over
HDMI. The two video signals can be routed to any sink devices which are connected to the device: the HDTV
and the projector.
