Yes it does, but their own advertising specifically disclaims that, eg:

"Not an HDMI Balun, but an HDMI over IP system. This means you can
create your own A/V Ethernet network and all of the recievers will
find the transmitter automatically. It may even be used over smaller
existing house networks and low cost LAN switches and routers."

BUT

"Video Bandwidth:  2.25Gbps (HDM1.3)
LAN Bandwidth: Maximum 50Mbps ~ 60Mbps for 1080p"


Its all rather confusing.

Never mind, I have no use for one so I'll forget about it now.
