Distance, data rate required, bandwidth (like RF signals), analog signals and timing that Ethernet does not provide. I suppose that you cable box could encode everything as Ethernet/IP to send it to your TV but it would take lots of processing horsepower to encode/decode. Your stereo could take the analog output going to your speakers and encode it as a digital Ethernet/IP signal but then you would need to decode and amplify it at the speaker. Some signals are better off as analog or RF end to end. Your FM radio antenna is going to be pretty expensive if you want to use Ethernet between it and your stereo receiver.

I'd turn this back the other way though: in this day and age, why do we have any interconnection/bus that isn't just ethernet/IP?
The need for isochronous transmission and more bandwidth. Tony. -- f.anthony.n.finch <dot () dotat at> http://dotat.at/ Forties, Cromarty: East, veering southeast, 4 or 5, occasionally 6 at first.
