Re: Hi-Def video senders (long post, sorry!)

[Jamie Whitehorn <jamie@xxxxxxxxxxxxxxx>]

I could be wrong about this, but I think the systems that use two
ethernet =
cables are simply dumping the HDMI signals down the wires (possibly with
am=
plification), hence they need 2 cables and are largely point to point. The
=
Just Add Power guys  (http://www.automatedhome.co.uk/New-Products/Just-Add-=
Power-HDMI-over-IP-2G-European-Launch.html) actually convert the HDMI
signa=
l and wrap it up in TCP/IP packet to send to the destination across the
sta=
ndard gigabit Ethernet network. Several advantages to it - you can
"broadca=
st" to several receivers, you can "group" receivers together
etc.

Usual disclaimer: Not connected to any of the companies, would love to use
=
Just Add Power, but can't afford it ...... yet.
