And it would have been offered ala USDTV ventures in 2001 if COFDM had 
been allowed. And it will be offered when and if there is a solid receiver.

Because they are not paying attention. If COFDM had been allowed others 
would have badgered broadcasters to pay attention. USDTV has gotten the 
attention some broadcasters who have invested in it. But again if we had 
a working modulation with inexpensive plug and play receivers all this 
would have/will happen. Would have happened in 2001, will happen whenever.

Broadcasters will start paying a lot more attention now that the 
deadline is set and will pay even more attention after multicast must 
carry is finally buried by Congress or the Supreme Court.

Problems are not solved. STB's that we know we can get today that are 
not as good as the prototype we have a possible business plan, with 
unavailable prototype quality receivers we have a better but 
uninteresting plan with receivers that are probably $100 to $150 more 
than what COFDM would cost but with COFDM today we have a very exciting 

Whatever the difference with the prototype only one thing matters, it 
doesn't exist.

We assume they will cost too much and they definitely don't exist. So 
that is why nothing is happening. So call LG and ask them why.
