Some hobbyists have built CC decoders to do other
things. Back in the nineties when O. J. Simpson was so much in
the news, somebody on the PIC microcontroller list built an O.
J. muter. Every time that name came up, it triggered the mute
function on the TV via the IR remote. I imagine this was more of
a joke because there wouldn't be any way to know exactly when to
un-mute the TV.
Also, somebody tried to market a similar device with all
the curse words programmed in to it. When a caption contained
four-letter words such as work, the TV would mute.
That was an actual product but I bet it went nowhere
because on live shows, the captioners are typing it
in as fast as their fingers will fly but it still lags the
actual speech you hear so one probably would hear the bad word
followed shortly by a break in the sound. The kids would still
be warped for life and the audio would then have a blank spot in
it so you could better hear the kid repeating what he or she
just heard. Then, you have a speech-recognition chip in the mute
box that listens for a child's voice saying whatever word was
just censored and a motorized paddle shoots out and delivers
automated punishment.
Bet you never thought technology could be so clever.
