I met with the developers and faculty advisor of this
board several months ago at the IEEE consumer
electronics conference in Los Angeles. The
capabilities of the board were impressive. They set up
a small demo playing back MPEG2 video from a hard
drive, converting it to 8VSB then to an RCA consumer
DTV receiver feeding the hotel room TV. The boards are
also able to do a number of other standards such as
DVB-S (the receivers for which are far cheaper that
the 8VSB units).

It looks like promising technology. Cost for their
initial build of 100 units (too late to get one if
you're not on the list already) is expected to be
about $700.  While out of reach of many home ATVers,
it might make a good club investment for an
experimental repeater output. Consumer 8VSB receivers
are going for about $300+, DVB-S set top boxes are
going for about $100-200. They are also talking about
OFDM and other modulation methods which would put high
quality video in bandwidths much less than 6MHz.
