Hi All,
Happy Holidays. Got a whole house application to share one FIOS STB/DVR (w/HDMI out) to 4 displays, hundreds of feet apart - ideally over single Cat5e.  Looking to avoid pulling add’l cable of I can. Anybody using any of the new HDBAseT stuff with any success?  oh, and need an IR back channel to the STB. Any pointers? Thx!

Audio Authority HD-IP. Works over IP similar to the Spatz/Just-Add-Power stuff but lacks the video switching. GREAT way to distribute a single HDMI source long distances over a single cat5/6. Includes IR back channel too

Infrared Resources has an excellent low cost HDMI over HDbaseT Extender Kit with Full HD support,IR,3D,4Kx2K over single CAT5e/6 up to 330ft
It does not have ethernet port but who even has equipment that needs it. Why pay for something you dont use currently or anytime soon.

Thanks all for the replies. Since I have to distribute 1 source to 4 destinations, is there an off the shelf way to do this via some HDBAseT headend, so I don’t have to buy 4 separate device pairs? Thx again.

Take a look at this Atlona piece - very positive feedback from our integrator clients on the Atlona extenders.  http://www.atlona.com/Atlona-1X4-HDMI-Splitter-with-CAT5-6-Outputs-and-3D-support-transmitter-ONLY-AT-HD-V14SS.html

Hey thanks Curt. That Atlona 4-way splitter would be totally perfect if it had integrated IR back channel.  Probably great for signage. 
I’m a bit leary with handling the IR returns separately over the same cable as the main feed, ESP with different vendors. That’s just begging for interop issues.
Thanks though for the heads up.
