Markey and Barton would be the two we should talk to.
This should be driven by the need for OTA to keep up with cable and
satellite by being able to using the latest MPEG4 like they are using.
This will be hard to refute on its face and harder to refute when it is
clear that this increases the value of the spectrum at issue by two to
three times. If it is worth a hundred billion now it will be worth three
hundred billion with MPEG4. Follow up by showing that the current
transition disaster is a blessing in disguise since little has been
invested by the public in receivers so far. Also if the government is
considering buying millions of receivers in bulk for those who still
depend on OTA analog then why not increase this number a bit to handle
the current 8-VSB early adopters also. The increase in value of the
spectrum makes any such investment seem very small.
And then the suggestion that since we are considering a new compression
codec and since that will obsolete all current receivers it only makes
sense to put everything on the table again including modulation. Might
as well take this opportunity to re-examine everything. Including DMB-T IMO.
