John, Frank,
 
I cannot help but think though, that because (a large portion of or
all?) the patent revenues may go to Korea, AND there have been
performance difficulties AND the relative cost of silicon to build an
ATSC receiver that performs well is expensive, then it looks like a 3
way loss situation. This is ironic as I understand that the US
originated COFDM modulation. Why wasn't there an effort to ditch the
ATSC modulation at the earliest opportunity if (a) the revenue was
likely to go overseas, and (b) there were strong indications of
performance limitations and (c) there was an opportunity to use a US
version of COFDM that you could get patent royalties from?

You are absolutely correct, and you are the only one on this list who
has talked publicly about THAT. The IP licensing cost of an ATSC
receiver/decoder will soon exceed the silicon + software cost, and a
chunk of that will go to LGE for the 8-VSB patents. We have discussed
this on OpenDTV many times in the past, including some news articles
that put a dollar figure on the IP windfall that LGE expects from the
ATSC tuner mandate.
