No. Not really. (unfortunately)<br>
<br>
The full bandwidth of HDMI (HDMI 1.3 can send up to 10.2Gbit/s although<br>
1080p is only around 4Gbs.) is higher than even wired ethernet. I've<br>
been thinking of doing something like myself , but it would probably<br>
require a clever FPGA, (getting a UDP/IP stack and compression inside an<br>
FPGA is I think doable) But that isn't remotely cheap - and I haven’t<br>
seen anything on the market similar to it.<br>
<br>
I think your best bet is sending the video stream while it is still in<br>
it compressed container and using a cheap computer - say a Raspberry Pi<br>
+ codecs to decompress at each (if there is more than one) display.<br>
Small form factor computer which can sit neatly behind the TV display<br>
are really good here. There are even full PCs small enough for this.<br>
