I guess I've been following this closer than all but a few members of this
list.
E-VSB is likely to be the only mobile broadcast standard approved by the
U.S, to the extent that it 1) is a MOBILE broadcast standard and 2) exists
at all.
As a practical matter, E-VSB required changes in the A/53 standard. Alas,
M/H doesn't require or involve any changes in A/53 to operate as planned,
hence ATSC M/H doesn't require any approval by the FCC. Basically, the
transmission involves data encapsulation on null packets. No FCC permission
is required to transmit null packets, and the maximum bandwidth that one can
devote to M/H still leaves ample room to send an SDTV-quality signal (plus
audio), plus PSI + psip).
To the best of my knowledge, no petition to start the process of FCC
approval has even been considered by the relevant parties.
The potential holdups are on the receiver/cell phone vendor side, not in the
realm of regulation.
"Game changer" in several regards.
Something is happening here ...
Or, I can throw it back to you. Just what in the candidate standard makes
you think that FCC approval is necessary?

conclusión vis a vis FCC approval in mid-summer, 2008.

year
Seeing as the only mobile standard thus far approved by the FCC for use is
E8-VSB, I wish all the best to the OMVC.

Sixty-three TV stations to launch mobile DTV service this year
Jan 13, 2009 8:12 AM
The first wave of mobile digital television broadcasting will break in 2009
with the commitment of broadcasters to launch mobile DTV across 63 stations
in 22 markets, covering 35 percent of U.S. television households, the Open
Mobile Video Coalition said.
During an OMVC press conference Jan. 8 at the International Consumer
Electronics Show in Las Vegas, the alliance of broadcasters backing mobile
DTV announced that 14 of the stations will be NBC affiliates, nine ABC
affiliates, nine CBS affiliates, five FOX affiliates, nine ION Television
affiliates, four CW affiliates and four MyNetworkTV affiliates. Nine
additional PBS stations are in discussions with the OMVC to join the 2009
launch.
The OMVC put on a live demonstration of mobile DTV broadcasting to show the
feasibility of the ATSC Mobile DTV Candidate Standard. Several Las Vegas TV
stations broadcast a variety of programming using transmission equipment
from Harris to ATSC-compliant mobile devices made by LG Electronics and
Samsung Electronics.
The OMVC and ATSC recently announced acceptance of a Candidate Standard for
mobile DTV that will be tested in multiple market trials during 2009,
revised as needed and proposed as a final standard by midyear.
