It is, although I really can't see much of a use for it (other than
maybe for stills). See
http://www.hdtvprimer.com/ISSUES/what_is_ATSC.html for a list of all 18
formats that are included in the ATSC specification (listed under the
column "Format name").

Wow. So--factoring in JDS's response (
http://www.gossamer-threads.com/lists/mythtv/users/131855#131855 )--does
that mean that local affiliates choose the format? It would make a lot
more sense for the major networks to choose a format and for their
affiliates to use that same format (i.e. NBC chooses 1080i and all
affiliates broadcast in 1080i). If the affiliates choose the format,
does that mean the networks provide both formats to affiliates? (I
can't see re-encoding of the real-time feeds actually working--not to
mention it doesn't make sense to re-encode from 720p to 1080i or vv.)
