A little way back, I remarked that I believe one of the aims of digital
TV is to provide a trojan by which DRM can be brought into the home.
It seems the EFF agrees:

> scheme called Content Protection and Copy Management (CPCM). Its
> unparalleled restrictions include:
> * *Enforcing severe home recording and copying limitations.* CPCM
> will allow content providers to apply copy restriction labels to
> broadcast streams. For example, a program could be marked as
> "Copy Never." In turn, your DVRs and others devices receiving
> the signal will have to obey and forbid copying even for home
> use. A content provider could opt to allow recording but still
> enforce a multitude of restrictions on copying to other devices.
> * *Imposing controls on where you watch a program.* Even if you
> are given permission to move a program to your laptop or other
> portable devices, "geography controls" may kick in and stop
> playback once you leave home or a particular locale. These
> restrictions may be enforced using tamper-proof GPS receivers
> built in to your devices. CPCM can also be used to block sending
> video to yourself over your own home network or the Internet,
> among other things.
> * *Dictating how you get to share shows with your own family.*
> CPCM can be used to examine, for instance, the frequency with
> which devices are connected to a personal network and determine
> whether your sharing is within an "Authorized Domain" Absurdly,
> DVB spent significant time arguing over what happens to a
> digital video in case of a divorce!
> * *Breaking compatibility with your devices.* You may have already
> invested in new high definition displays and receivers that rely
> on component analog connections or unrestricted digital outputs,
> but CPCM will allow the studios to arbitrarily block these
> connections. In other words, individual copyright holders can
> turn your gadgets into oversized paperweights. CPCM- restricted
> media will also be able to carry blacklists and revoke
> compatibility with particular devices that don't enforce
> Hollywood's restrictions sufficiently.
So; the consumer is merely a participant in a cargo cult. Dress up the
technology as an "upgrade" and any sucker will buy anything, with a
conga line of ... reviewers ... to say "it's wonderful, you get better
pictures, the sound is crystal clear!" and so on.
Some 'digital dividend'.
