Yes, granted. I was only responding to the more current mantra that
COFDM "was designed for" SFNs, which it was not originally, and that
SFNs would save untold 100s of MHz of spectrum for the FCC, which
they would not. At least, not without other changes.
And who has been delivering this mantra?
I have not seen anyone ever say that COFDM "was designed for SFNs."
But it is an option that was enabled by the manner in which the
standard was implemented.
And those choices can change over time without obsolescing
existing equipment in the field.
Heh. Tell that to the folks who need to buy DVB-T2 STBs just to watch HDTV!!
Nobody ever told these folks that they would get HDTV via DVB-T. What
they were told, AND GIVEN, was a viable standard that exploited the
investment made by Euro broadcasters in ITU-R BT 601 digital video
equipment, including widescreen video. They were given VERY
AFFORDABLE DTV receiver boxes that have served their purpose well.
The need to upgrade is not an evil thing if you are getting a new
generation product that offers enough advantages to justify the
upgrade. And it is not like the existing DVB-T systems are shutting
down - those Freeview boxes are still quite useful, especially for
the smaller TV that most Europeans own.
Now that HD is a viable industry Euro consumers have the option to
buy new displays and receivers that are still backward compatible
with the DVB-T system.
This is exactly the business model that many advocated when the U.S.
DTV standard was created. But we got a government mandate for ATSC
receivers that most folks do not use instead.
By the way. I think people are going to need new receivers for ATSC MHP...
