I have an LG TV with a 3.0 Tuner. I don't know if my local broadcasts are in true ATSC 3.0 but I get pixelization, where as I do not have any issues on the 1.0 broadcasts.
I can't see 1.0 going away until every television sold has a 3.0 tuner, and then it will be another 10 years after that. Its going to be the same transition we went through from Analog to digital
Whatcha smokin' to give you such dreams?
