Which brings up the point of QAM on the pcHDTV. I emailed support, and
they said that the OREN OR1211 chip that they're using supports QAM. They
haven't gotten it to work, but I don't know how hard they've tried. I also
don't know the development environment (anything proprietary in the drivers or
hardware?).
I suspect that with the broadcast flag enforced for copy "protection,"
and QAM for closed-circuit bandwidth conservation, cable companies might start
broadcasting unencrypted QAM channels. I thought that FCC et al. wanted to
have consumer-grade "HD cable-ready" TV's and such to work without magic settop
boxes. The broadcast flag allows for unencrypted, but "protected" streams to
come down the wire to a cable-ready tv. Of course I could be all wet and
they'll require a magic box to get *anything* over the cable soon.
