Bob,
I would testify that:
1) The advantages of use of H.264 over MPEG-2 warrant a reexamination of
the US Digital Television specifications, where a single 6MHz channel could
now support multiple HD signals or many more SD channels.
2) That a COFDM variant (DVB-T or the more robust emerging Japanese COFDM
based standard) would best serve the USA
3) That the new specification would provide for native IP handling, to
easily facilitate data broadcasts to home users.
4) That the new standard would include Emergency Broadcast modes, such as
in DVB-T, where the effective data rate is reduced from the normal mode
18Mbps (or so) down to 6Mbps (or so) to deliver a very, very robust signal
strong enough to punch through any possible storms, reaching into
basements, etc.
5) That broadcasters would use the same frequencies as already allocated
6) That all diverse repeater frequencies be canceled, and require the use
of on-channel repeaters (easy to do under COFDM/DVB-T)
7) And maybe suggest that the VHF spectrum be closed out / reallocated to
public use, putting all broadcasters in the same power consumption mode
(level the playing field).
8) That low cost receivers be made available, including subsidizing, for
citizens below the poverty line, financed from the spectrum fees
9) That low cost COFDM to 8VSB translators be made available (sort of like
the RF CH3 adapters that use to be sold with VCRs) to allow any existing
built-in 8VSB receiver be able to be used as part of the switrchover to COFDM.
10) That broadcasters would be allowed to do a one-time single year
depreciation of their 8VSB transmitter exciters, so that they may purchase
COFDM exciters.
This list off the top of my head. I would clearly put more effort into any
requested expert testimony.
