When I heard it, I thought that the possible help from AVC was just

So I don't think the argument against AVC is only a matter of
installed base, important as that certainly is. Seems to me, it just
won't help as much as the hype was suggesting, for SD or HD TV.
Once again, Bert has missed the forest for the trees.
Setos et al were not making a technical argument about the efficiency
of AVC, WHICH IS being deployed for IPTV BECAUSE of the efficiency
advantage.
They were making a political argument about protecting the castle
that they built with ATSC and MPEG-2. You know the castle that is
surrounded with moats filled with nasty lawyers and bureaucrats...
It took more than a decade to build the industry and political
consensus needed to replace an outdated NTSC system. In the end they
managed to replace it with a digital system all wrapped up in
protected IP and a government mandate to deploy millions of
ATSC/MPEG-2 receivers that are for the most part NOT being used.
It should come as NO SURPRISE, that broadcasters would now use the
very limitations of this infrastructure to PROTECT it.
Andy (Setos) is probably being conservative in saying that it would
take a decade to replace all of the ATSC receivers that are now in
place (and the tens of millions that will be sold in the next few
years).
The bottom line, according to broadcasters, is that the FCC proposal
would require ANOTHER DTV transition...
How convenient.
