Yes, but let's not go around in a circular argument.
There is no question that a broadcast protocol is simple. There is no question
that piping, simultaneously, even 100s of HD streams, via broadcast, into every
home, is technically the easiest way to go. That's why a broadcast scheme that
is already in place. Simple and elegant.
The question is, once you have a way to use the ISPs' routed IP nets to do this
same job, along with the other stuff they can do, and once you have the
congloms willing to work over these ISP nets directly to customers, won't that
change everything, potentially? It's still possible to use carburetors to mix
air and fuel in an engine, and it's the simplest way to get the job done
(ignoring emissions), but does anyone care?
Take a traditional cable company with an HFC infrastructure. What would prevent
this cable company from dedicating all of their 6 Mhz channels, in the coax
parts of their nets, to IP (DOCSIS), and none to the TV broadcast channels?
The coax parts of the system, which are used to fan out to some ever shrinking
number of individual homes, is still capable of carrying over 4 Gb/s of
download traffic. Not half bad. No so different from the FTTH systems, in
practice.
No worries, though. History has shown, with cable and DBS, that the balance
happens because people get overly greedy. Even if the congloms allow direct
access to their content, trust the ISPs to begin charging an arm and a leg for
their part of the service. So just like now, broadcast can bypass the
bottlenecks.
