IBOC is a temporary compromise. Eventually analog will be turned off and
HD Radio will be all digital.

Ah, yes... yet another denial of service to rural users of the media, just
like HD(?*)TV has been. I guess if you don't live in a core city area, you
just don't count (sort of like if you're over 50).

* Quite a bit of supposed HDTV, isn't. Stations that have multiple channels
cannot use full bandwidth for their main channel. Most don't use 1080p,
opting for 720p with an additional channel or two. The ones with 5 side
channels can't even use 720p, and run mostly 480p, which is only marginally
"better" than good old NTSC analog (and you could still receive the analog
signal at a distance, which you cannot do with ATSC.)

Ah Yes Indeed ) !

But Then "All Advertising Is Local" {Protecting the
Revenue Stream} and Rural {Local} AM/MW Radio
Stations will then have a 'captive' audience of rural
AM Radio Listeners who will only hear the IBOC

Rural residents willingly give up certain services because the cost of
providing the services is prohibitive. No piped natural gas, often no
cable TV, often no sewers. There are workarounds at higher cost. For
radio there is satellite radio versus terrestrial radio.

Rural radio stations can provide digital service if they desire.

What's lost with digital AM is the ability to receive distant stations,
but that was never guaranteed to either the stations or the listeners.

The "standard" for North American terrestrial transmissions is
1080i not 1080p, or as you say 720p@60.

The bandwidth of the UHF channels (6 MHz) is inadequate for 1080p@60.

A possible compromise is 1080p@30, or for movies 1080p@24
but not terrestrial TV transmissions in North America use
this mode.
See the list of official ATSC modes at

http://www.hdtvprimer.COM/ISSUES/what_is_ATSC.html

In Europe where the mains frequency is 50 Hz as opposed to the
North American 60 Hz, the TV norm is similarly 50 Hz, and the
equivalent resolutions are 1080p@25 and 1080p@50.

Again because there is not sufficient bandwidth for 1080p@50,
broadcasters use either 720p@50 or 1080i. The BBC on terrestrial
transmissions has started dynamically switching the transmission mode
on their BBC HD station from 1080i to 1080p@25 and back when it is
appropriate for picture content (material recorded on location
as opposed to studio content).

This caused a problem for some SONY televisions.

http://www.engadget.com/2011/05/23/bbc-hd-quietly-begins-broadcasting-in-1080p-but-not-all-sony-hd/

A check on Wikipedia reveals that some North American stations
on satellite do broadcast 1080p@24 or 1080p@30 as appropriate.

Please note that the maximum resolution supported by BluRay
is 1080p@24, or 1080i@50 or 1080i@60, bit *not* 1080p@50 or 1080p@60.
