[opendtv] Re: Italian mobile TV provider has signals covered

I would like to correct the tone of my last post.
Over the last years a number of fixes or advances have been made to 8-VSB.
Most have been disapointments. In the little research I have done on A-VSB I
have made notes. I am not an engineer.

My last post was an attempt to list the potential for A-VSB, as I understand
it, and to elicit responses. Learn more about it.

I have been informed that I am way off base. Probably am since people and
companies that I respect are excited about its potential.
