Anyone have a list of those 22 cities yet? I can't wait to watch TV while stuck in traffic. I can watch the news about the traffic jam being caused by some idiot watching TV on his phone. :D

So I'm confused, why couldn't you simply get an ATSC broadcast on a mobile device? Is it simply b/c the hardware to tune and decode it is too expensive/cpu hungry? If so, won't that not be the case in a few years (as hardware gets better and prices go down)? Seems like a short term solution to a non-existant problem.

The serious issue with regular ATSC is that it has poor resistance to things like movement. If you're trying to watch an ATSC broadcast in, say, a car, it's going to regularly break up due to the excessive doppler effect and changing multipath interference dynamics.
The ATSC has proposed two standards, E-VSB and ATSC-M/H, to fix these issues, although the former never took off. The standard does take bandwidth away from the regular ATSC HD channels for use with the mobile versions.

Thanks for that clarification. I never knew regular ATSC broadcasts has such issues with moving antenna.
