while words are important, Frank, we're in complete agreement on this point,
which I've made for about 30 years.

Thanks John for correcting Bob's misstatement about XM & Sirius' terrestrial
repeater network. They use (C)OFDM systems, but not DVB-T. Just as 802.11a &
802.11g are (C)OFDM systems, designed to a different set of specifications than
either DVB-T or XM or Sirius.
Leave it to you, the closet lawyer, to make all this noise about the precise
definition of "broadcasting." I submit that American consumers don't care about
your definition, or mine, or the FCC's. They know "television programming" when
they see it, and they know "wireless" services when they see those -- and they
don't routinely think of "television programming" as being a "wireless"
service. That view may change when enough laptops and cellphones are enabled
for wireless video via DVB-H. It is extremely unlikely that such portable
devices will ever be enabled with ATSC receivers, for technical and economic
reasons. The phrases "low power," "low cost" and "reliable" simply don't apply
to ATSC receivers, and probably never will.
