Dunno about that, Mark. I read in there the same old tired generalities that 
I've heard from some on this list, for the past 10 years or so.
 
Of course the OTA spectrum can be turned into two-way video on demand service. 
And you can even mix in some IP multicast streams in there. Seems to be what 
he's advocating. But there's absolutely no silver bullet that will create more 
spectral efficiency out of it. The whole spectrum can be repurposed to cellular 
wireless instead of broadcast. The cost of infrastructure goes way up, and the 
service becomes another telco-like service. AND the spectrum now used by 
broadcasters won't be capable of carrying as many "broadcast" or IP multicast 
streams as it now can, as a purely broadcast service.
 
(A cellular infrastructure is not an SFN. *And*, even if by some unpsecified 
magic we create an SFN out of only some towers, the ones used in IP multicast 
streams, the single-market aspect that US TV requires prevents any spectrum 
savings from SFNs anyway. Not to mention, just creating the SFN eats up 
spetcrum.)
 
Just state it in simple terms, rather than the "unleashing" and the "more 
efficient schemes out there" vaguaries.
