I wonder how the Limo's will deal with DTV in motion.


Ahah! Presently they don't. A big issue for opponents of 8VSB modulation
was poor performance in mobile/handheld (M/H) applications. Straight 8VSB
does not handle "dynamic multipath" well.

However ...

Development of the ATSC-M/H Standard for mobile
and handheld applications is moving forward at a
rapid pace. A critical element of that effort is the
Independent Demonstration of Viability (IDOV).
The goal of IDOV is to ensure that the technical
proposals under consideration can meet the goal
of enabling mobile and handheld services in early
2009.

per http://www.atsc.org/communications/n...r_standard.pdf -

I read some news accounts of supposed successful tests (the "IDOV" ?) this
past spring. We'll see.

BTW, alt.video.digital-tv newsgroup is doing a good job with the TV
transition. Also,
http://www.avsforum.com/ has news, like
