John, this still sounds absurd.
CE companies, and all manner of other companies making
consumer products, have no problem whatever accommodating
different standards and different laws for the different
markets they want to serve. Look at auto companies, for
example, and the considerable extent they go to. As to CE
companies, they have accommodated different power
standards and different analog TV standards forever, with
no major problem. Modulation differences for DTT is a
piece of cake, especially since March of 2002, when decent
equalizers that work were first demoed.
The market for ATSC is huge, compared with the market for
DVB-T in the UK alone, which CE companies met quickly and
gladly for many of the initial years of DTT.
I'm sorry, but this idea that DVB-T would resolve this
state of affairs just sounds like a fairy tale.
