Frank,
First of all, both cable and broadcasters have access to the Terayon Cherry
Picker which can "groom" bitstreams to any bitrate you wish, so it is very
easy for cable headends to lower the HD bitrate of broadcasters.
Secondly, digital must carry rules state that if a cable company carries a
broadcaster in HD, they must carry that broadcaster in the same resolution
that they carry other HD services, but not necessarily in the same
resolution and/or bitrate the broadcaster is using. So if a cable company
squeezes Discovery HD to 12 Mbps, they can squeeze CBS HD to 12 Mbps.
From FCC R&O FCC01-22:
"From our perspective, the issue of material degradation is about the
picture quality the consumer receives and is capable of perceiving and not
about the number of bits transmitted by the broadcaster if the difference is
not really perceptible to the viewer. Such an interpretation is consistent
with the language of the Act, which applies to material degradation, not
merely technical changes in the signals."
Third, as far as our PBS station goes, we are required to simulcast 75% of
our OTA signal on the DTV channel, and at the same time our digital viewers
want the PBS HD service. Therefore we have no choice but to multicast both
an HD and an SD.

local broadcaster who deteriorates the quality of the network HD feed, just
so he can multicast an HD and an SD program on his DTV channel.
