The major problem facing Hollywood in protecting their HD content is that
it runs smack up against an installed base of millions of HDTVs with only
ACV (analog component video), including mine. These consumers were
promised by the FCC that they would not be left to twist in the wind when
newer set-top-box to TV connections evolved and it does not appear
technically practical to retrofit these sets to accommodate encrypted DVI
or Firewire inputs. The FCC has already stated they do not support
broadcast flags for pay content and unless they back-peddle on this
Hollywood appears to have only three other options: restrict the
availability of HD content to cable broadcasters, prevent the sale of
devices that can capture HD quality content from ACV, or insist that the
resolution of ACV signals be degraded when "copy restricted" content is
being broadcast.
The first will bring great howls from existing HDTV owners with only
ACV. The second is probably impractical since illegal devices (little more
than 3-channel A-D converters on a PCI card) are sure to be produced and
only a small number in the hands of skilled movie releasing groups are
required to widely disseminate their content via the Internet. The third
option is also sure to bring major complaints from existing set owners.
