<p><a hreflang="ja"
href="https://ja.wikipedia.org/wiki/B-CAS">B-CAS</a> <a
href="#m1">[1]</a> is the digital restrictions management (DRM) system
used by Japanese TV broadcasters, including NHK (public-service TV).
It is sold
by the B-CAS company, which has a de-facto monopoly on it. Initially
intended for pay-TV, its use was extended to digital free-to-air
broadcasting as a means to enforce restrictions on copyrighted
works. The system encrypts works that permit free redistribution
just like other works, thus denying users their nominal rights.</p>
<p>On the client side, B-CAS is typically implemented by a card
that plugs into a compatible receiver, or alternatively by a tuner
card that plugs into a computer. Beside implementing drastic copying
and viewing restrictions, (追記ここまで) this (削除) harassment, (削除ここまで) (追記) system gives broadcasters full power
over users, through back doors among other means. For example:</p>
<ul>
<li>It can force messages to the user's TV screen, (追記ここまで) and the (削除) fundamental wrong (削除ここまで) (追記) user
can't turn them off.</li>
<li>It can collect viewing information and send it to other
companies to take surveys. Until 2011, user registration was
required, so the viewing habits of each customer were recorded. We
don't know whether this personal information was deleted from the
company's servers after 2011.</li>
<li>Each card has an ID, which enables broadcasters to force
customer-specific updates via the back door normally used to update
the decryption key. Thus pay-TV broadcasters can disable decryption (追記ここまで)
of the (削除) DRM in DVDs, (削除ここまで) (追記) broadcast wave if subscription fees are not paid on time.
This feature could also be used by any broadcaster (possibly
instructed by the government) to stop certain persons from watching
TV.</li>
<li>As the export of B-CAS cards (追記ここまで) is (追記) illegal, people outside Japan
can't (officially) decrypt the satellite broadcast signal that may
spill over to their location. They are thus deprived of a valuable
source of information about what happens in Japan.</li>
</ul>
<p>These unacceptable restrictions led to a sort of cat-and-mouse
game, with some users doing their best to bypass (追記ここまで) the (削除) requirement (削除ここまで) (追記) system, and
broadcasters trying (追記ここまで) to (追記) stop them without much success: cryptographic
keys were retrieved through the back door of the B-CAS card, illegal
cards were made and sold on the black market, as well as a tuner for
PC that disables the copy control signal.</p>
<p>While B-CAS cards are still in (追記ここまで) use (削除) nonfree (削除ここまで) (追記) with older equipment, modern
high definition TVs have an even nastier version of this DRM (called
ACAS) in a special chip that is built into the receiver. The chip
can update its own (追記ここまで) software (追記) from the company's servers, even when
the receiver is turned off (but still plugged into an outlet). This
feature could be abused (追記ここまで) to (削除) play (削除ここまで) (追記) disable stored TV programs that (追記ここまで) the (削除) DVD. Fortunately we have (削除ここまで) (追記) power
in place doesn't agree with, thus interfering with (追記ここまで) free (削除) replacement software.
</p> (削除ここまで) (追記) speech.</p>
<p>Being part of the receiver, the ACAS chip is supposed to be
tamper-resistant. Time will tell…</p>

translated this article from Japanese, and shared his experience of

<p>DRM does more nastiness to published works than merely stopping
people from looking at and/or copying them. Even when it allows you to
look, it harasses you in many ways. Cory Doctorow's article presents
<a href="https://boingboing.net/2010/02/18/infographic-buying-d.html">
DVDs as an example</a>.</p>
<p>We condemn the propaganda term “pirate” when it
is applied to people that share copies. Many of these DVDs are
made and distributed commercially; in reference to that practice,
“pirate” might be partly justified. But not when they
protect users from harassment.</p>
<p>The fundamental cause of this harassment, and the fundamental
wrong of the (追記ここまで) DRM in (削除) Cars Will Drive Consumers Crazy</a>.
